Dear Support,

I have a drop-list cell of type CExtGridCellDropListComboBox, and when the user changes the selection I need to reset several depending cells. However, if the user selects the same item that was selected before, I do not need to do anything.

The problem is that I use OnGridCellInputComplete as my event handler for the drop-list change, and even if the user re-select the same item this event is called.

Is there a way to prevent this at the cell level, so that if the same item is selected it will not call OnGridCellInputComplete? or do i need to implement such mechanism to remember lat selected item?

Thanks,

Ron.

The CExtGridCell::OnPopupListBoxSelEndOK() virtual method handles the selection of a list box item and invokes CExtGridWnd::OnGridCellInputComplete() . We assume the selection of the same list box item can be useful because it can be interpreted as an event for refreshing some data views in your application. For your convenience, we added the following grid cell style which makes all the CExtGridCell***::OnPopupListBoxSelEndOK() virtual methods not invoking the the CExtGridWnd::OnGridCellInputComplete() virtual method if the text of the selected list box item is equal to grid cell text:

Hi,



We have a bunch of dialogs that draw custom stuff in OnPaint(), but now with ProfUIS, much of it doesn’t appear.



Some of this is because Prof-UIS has filled group boxes, instead of empty (why is this?  Shouldn’t the skinned background come from the dialog itself?).  How do I ensure OnPaint() stuff is drawn after other controls?



But there’s also other stuff that isn’t showing up, even though those dialogs have no group boxes.  Any ideas?



Thanks,

Rob.

So is this the simplest/recommended way even for drawing stuff in the foreground?  I don’t need what I draw to show through other transparent controls for the most part.  I just need a way to draw stuff that won’t overlap other controls.

Rob.

If you don’t need to draw compound inherited background, then you should simply handle the WM_PAINT message in the WindowProc() virtual method:

virtual LRESULT WindowProc( UINT message, WPARAM wParam, LPARAM lParam ) 
{
            if( message == WM_PAINT )
            {
                        CRect rcClient;
                        GetClientRect( &rcClient );
                        CPaintDC dcPaint( this );
                        CExtPaintManager::stat_ExcludeChildAreas( dcPaint, m_hWnd, CExtPaintManager::stat_DefExcludeChildAreaCallback );
                        CExtMemoryDC dc( &dcPaint, &rcClient );
                        //
                        // First of all we will paint default themed background.
                        //
                        if( ! ( g_PaintManager->GetCb2DbTransparentMode(this) && g_PaintManager->PaintDockerBkgnd( true, dc, this ) ) )

Dear Support,

Any news when 2.84 will be released?

Thanks,

Ron.

First of all, this problem is well known as principally never fixed issue of Windows XP and later versions:

http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=354617

It appeared many years ago with release of Windows XP and still not fixed. Probably, it’s easier to code new OS than fix this problem. The fixes like the following one are incorrect:

http://www.codeproject.com/KB/bugs/MDIFlick.aspx

Now the good news. It looks like we fixed it. Here is the ZIP file with compiled sample MDI applications:

http://www.prof-uis.com/download/forums/tmp/MdiFlickerFreeTests284.zip

The problem appeared when you are activating MDI child frames via menu because the CMDIFrameWnd::OnCommand() virtual method handles these menu commands in a special way when Prof-UIS expects to intercept classic WM_MDIACTIVATE messages. Now Prof-UIS also handles the MDI window menu commands in the overriden OnCommand() virtual method of the code>CExtNCW < CMDIFrameWnd ></code> specialized template class.

It also looks like all the other known problems with skinned MDI child frame windows are gone because Prof-UIS 2.84 implements most of the MDI interface features manually (window tiling and cascading for instance). We had no chance to avoid this.

Does it fix the bug in view swithcing in MDI I reported?

http://www.prof-uis.com/prof-uis/tech-support/support-forum/any-progress-with-this-bug-where-you-able-to-reproduce-it-62608.aspx#@lt;/p>

This is very important to us that this bug is fixed for swithcing to 2.84

Thanks,

It is scheduled for December 15. We are sorry for the delay.

My grid window contains some editable CExtGridCellDateTime cells. I’ve added __EGWS_BSE_BUTTONS_IN_FOCUSED_ROW style to grid to see dropdown buttons of selected rows only.

Is it possible to set dropdown button of some datetime cell individually to be always visible?

It seems that cell->ModifyStyle(__EGCS_BUTTON_DROPDOWN ) does not help.

Thank you

I’m just learning Prof-UIS so I created an application that uses toolbars, the statusbar and a few controls.  When I compile it in Release mode with static libraries, the executable is 6.7MB.

I followed your instructions on size reduction, un-commenting all the Prof-UIS.h defines except:

//#define __EXT_MFC_NO_DYNAMIC_BAR_SITE

//#define __EXT_MFC_NO_SCROLLWND

//#define __EXT_MFC_NO_STATUSBAR

//#define __EXT_MFC_NO_NC_FRAME

I also excluded all the foreign languages.  And yes, I did rebuild the libraries.

Why is it still so huge?

Prof-UIS currently does not support pre-processor macros variables for excluding particular paint manager classes from the build. But, if you don’t need the Office 2007 themes, you can comment out the following line in the ...\Include\Resources\resource.rc file:

#include "Res2007\\Res2007.rc"

Is there a way to include just ONE of the themes?

Hello.

I want to delete the line of the place that I surrounded in a red circle

  ---->  

I’m having lots of problems putting controls on toolbars successfully.  Sorry if I’ve missed something obvious.



(1) None of CExtBarLabelButton, CExtBarCheckBoxButton or CExtBarRadioBoxButton appear in any of the sample code.  A label is put on a toolbar in the ProfUIS_Controls sample, but it is done differently, by creating a CExtLabel and adding it with SetButtonCtrl().  One problem with this approach seems to be that it disappears when the toolbar is resized (to split over multiple lines).  Why is that?  Can it be avoided?  Should the CExtBar*Button classes avoid that problem?



(2) When attempting to use CExtBarLabelButton, how do I set the text for the label?  Nothing I’ve tried has worked.  Same question for CExtBarCheckBoxButton.



(3) Is the only way to set the width of a label or check-box in a toolbar to derive new classes and override CalculateLayout()?



(4) Some reason when I create a CExtBarCheckBoxButton in your ProfUIS_Controls sample code and add it with InsertSpecButton() to a toolbar, it works (but without showing any text).  However when I do the same thing in my own code, it fails, just leaving the original icon button there.  One thing that’s slightly different is that in my code I am replacing existing buttons, first with InsertSpecButton() to add the new one, then with RemoveButton() to remove the original one.  They have the same ID though, so is it possible the customization module is changing my check box back to whatever it thinks the button should be?  Any other suggestions?



(5) I understand what you mean about making the label part of the combo box, and see that it would be a better option, but haven’t tried that yet.  That may circumvent my problems with CExtBarLabelButton, but I still have all the same problems with CExtBarCheckBoxButton.



(6) I tried using SetButtonCtrlVisibleVertically() for various controls, but they just appear as wide blank areas when docked vertically.  Eg edit and combo boxes behave that way.  Am I doing something wrong or is this just a known limitation?



Maybe you could add some sample code to demonstrate creation of labels and check boxes on toolbars, via the CExtBar*Button and InsertSpecButton() method, which seems preferable?  Showing how to control the width and text on such controls.



Thanks,

Rob.

Hello.

Scenery becomes black as follows when I use CExtWFF.

I decide to just use CListBox.

Is there a problem?

Hello.

When Bar was done Show of, please teach a called virtual function.

Thanks, 

Please process a WM_WINDOWPOSCHANGED message in the WindowProc() virtual method so that you can check if the control bar is visible using the CControlBar::IsVisible() method.

You should handle a WM_WINDOWPOSCHANGED message for your control bar and determine whether the control bar contains the WS_VISIBLE style . It should be created without the WS_VISIBLE style.

Hello.

What kind of message should I judge it by?

The window displayed from auto-hide tabs using the sliding animation is called the auto-hide slider control. This window looks like control bar but it’s not a control bar. The bar’s child window (color picker on your screen shot) is temporarily moved into the auto-hide slider window when it should be displayed from auto-hide tabs. So, the bar’s child window can simply handle the WM_WINDOWPOSCHANGED message and detect whether it’s parent is the CExtControlBar window. If the parent of color picker window is not the CExtControlBar window, then the color picker is displayed from auto-hide area.

I want to catch WM_SHOWWINDOW.

In WindowProc, I cannot catch it

There is a CExtControlBar::OnControlBarPositionChange() virtual method ,which is invoked when the window visible state and/or window position the control bar has changed.

<![endif]-->Hi!

I have a question regarding menus, actually it’s for all kind of GUI resources but we stick to menus for convenience.

We have split up an application in smaller parts with several dll:s with different resurcs like menus, dialogs etc. We’re not really sure how to get it to work with ProfUIS though. We have a base application which holds the main menu that every application got. For each dll they could add their own menus to the application. The main menu is loaded according to your specifications in samples and tutorials.<o:p></o:p>

The question is how to correctly load more than one menu during runtime (created in the VS resource editor) and merge it with a previously created CExtMenuControlBar.

Thanks in advance!

I’m sorry, I didn’t explain the problem as clearly as I should have.

We have everything setup with MFC extension DLLs containing MFC resources as menus for instance. We load the DLLs at runtime without problem but we’re not sure how we correctly merge the menu in a  DLL with the CExtMenuControlBar declared in our application. With correctly I mean how it’s supposed to be done to work as it should with ProfUIS. I’ve seen functions that merge two HMENU:s but I guess we need to do something with statBasicCommands for instance, and if so is it possible to do it at runtime?

You can invoke the CExtCmdManager::UpdateFromMenu() method many times for updating the command manager from all the menu resources in your DLLs. Of course, all the commands in all the menu resources must have unique command identifiers. If you need to display menu in the menu bar which is combination of several menu trees, you need to code your own recursive function which will merge menu trees. This is a very specific feature. Please provide us with more details.

You should create your DLL projects as MFC extension DLLs rather than MFC regular DLLs. The MFC extension DLLs cannot be used from non-MFC-based EXE modules. This should not be a problem. The most important thing is that you can use MFC class instances and resources of MFC extension DLL from EXE’s source code. If you need to load MFC extension library dynamically, you should use the AfxLoadLibrary() function from MFC instead of the LoadLibrary() Win32 function.

Hello.

 The anchor of the dialogue that I assigned to a bar does not work when I do following how to use 

 m_pRitsumenBar->SetRedraw(false); 

 m_pRitsumenBar->FloatControlBar( CPoint(480, 200) );

 m_pRitsumenBar->HideBar();

 m_pRitsumenBar->SetRedraw(true);

I have a CExtToolControlBar in a CWnd in a CExtControlBar (like the Open GL sample app). The CExtControlBar is docked in an MDI child window.

When the CExtControlBar is docked in the child window, the enabled/disabled state of the toolbar buttons is determined by the corresponding ON_UPDATE_COMMAND_UI functions in the child window (like normal). However, when the CExtControlBar is undocked, the buttons all go disabled.

It seems unusual that the buttons go disabled when the control bar is undocked. Any idea how to fix this?

Thanks.

Please add the following properties into your CWnd-derived class:

protected:
            bool m_bEnabledControlBarUpdate:1, m_bInConrolBarUpdate:1;

   : m_bEnabledControlBarUpdate( false )
            , m_bInConrolBarUpdate( false )

void CExtResizableDialog::PreSubclassWindow() 
{
            CWnd::PreSubclassWindow();
            m_bEnabledControlBarUpdate = true;
}

void CExtResizableDialog::PostNcDestroy()
{
            m_bEnabledControlBarUpdate = false;
            CWnd::PostNcDestroy();
}

LRESULT CExtResizableDialog::WindowProc(UINT message, WPARAM wParam, LPARAM lParam) 
{
bool bUpdateBarsOnThisMsg = false;
            if( m_bEnabledControlBarUpdate )
            {
                        CWinApp * pApp = AfxGetApp();
                        ASSERT( pApp != NULL );
                        BOOL bIdleMsg = pApp->IsIdleMessage(
#if _MFC_VER < 0x700
                                    &pApp->m_msgCur
#else
                                    &(::AfxGetThreadState()->m_msgCur)
#endif
                                    );
                        if( bIdleMsg )
                                    bUpdateBarsOnThisMsg = true;
            }

HWND hWndThis = m_hWnd;
LRESULT lResult = CWnd::WindowProc(message, wParam, lParam);
            if(                     hWndThis == NULL
                        ||           ( ! ::IsWindow(hWndThis) )
                        )
                        bUpdateBarsOnThisMsg = false;

            if(                     bUpdateBarsOnThisMsg
                        &&        ( ! m_bInConrolBarUpdate )
                        )
            {
                        m_bInConrolBarUpdate = true;
                        CExtControlBar::DoCustomModeUpdateControlBars( this );
                        m_bInConrolBarUpdate = false;
            }
            return lResult;
}

I take that back - that didn’t completely fix the problem.

Now, at least the command routing (of the buttons in the CExtToolControlBart) goes to its parent CWnd. However, it doesn’t go beyond that. For example, when handling the OnUpdateCommandUI for the toolbar buttons, any change to the state of the buttons in the rest of the app doesn’t change the state of the buttons in the said toolbar.

Figured it out - I needed to add the line:

(CExtToolControlBar).m_bPresubclassDialogMode = true;

Yes, that’s right. The improvement we suggested in our previous answer will do the guaranteed command processing in the same way like MFC does in frame windows.

Hello.

Please teach a part equivalent to CTabCtrl in Prof-uis.

We have three types of tabs:

1)    The CExtTabWnd class implements a single line tab window. There is a set of different styled versions of this class: CExtTabFlatWnd, CExtTabButtonsWnd, CExtTabWhidbeyWnd, and CExtTabOneNoteWnd. It’s not difficult to create a new themed version as it is demonstrated in the following test project: http://www.prof-uis.com//download/forums/TestIE7Tabs.zip

2)    The CExtTabMdiWnd class implements a single line MDI tabs window. There is a similar set of styled MDI tabs.

3)    The CExtTabPageContainerWnd implements a container window which uses CExtTabWnd single line tabs to change the selected window. There is also a similar set of styled tab page containers.

All classes are not based on the CTabCtrl class.

Hello.

When I want to use CTabCtrl by all means.

Should I just use CTabCtrl?

I use EnableWindow(FALSE) to set the state of a CExtComboBox in a CExtToolControlBar to disabled. Immediately after the call, the combo box goes disabled. However, whenever I move the cursor over the box, it becomes enabled again.



How do I keep it disabled?

I have a CExtToolControlBar and I put a CExtComboBox into it. How can I make a text label show up next to it like it would for a regular button?

I discovered a little more regarding my problem posted earlier.  The default width for a CExtBarTextFieldButton is 100 pixels.  However, in our derived classes we specify other widths in the constructor, eg 30 in this example:

MyTextField::MyTextField() : CExtBarTextFieldButton(false, 30)
{
}

So onto my label field.  Remember I said that with method (2) the label came out in the wrong place, part-way through a text field earlier in the toolbar?  Well, measuring distances, it appears that it would be in the right place IF the other text fields had appeared in their appropriate widths.  So I guess the only problem here is that those text fields don’t come out in the width I set.

Any thoughts?

Thanks,

Rob.

I’m also trying to insert a label on a toolbar, but am having trouble getting it to work.

It seems there are two ways:

1. Create a CExtBarLabelButton and insert using InsertSpecButton()


2. Create a CExtLabel and replace a place-holder button with SetButtonCtrl()

Is there any reason to use one over the other?

Method (1) is not used in any of the sample code and I can’t get it to work.  How do I specify the text for the label?  What about the width?

Method (2) I did get to work, sort of, but the label appears on the wrong part of the toolbar!  It starts half way through another edit control.  This toolbar already has other edit-boxes and similar appearing on it, using custom classes derived from CExtBarButton.  Is it necessary to derive a new class just to insert a label?  Is there a problem mixing methods (1) and (2)?

Thanks,

Rob.

It is not the best option to insert a label as a standalone button. A combo box and its label then may turn out to be in two different rows in a floating toolbar, which is resized for displaying its buttons into more than one row. So, we think the best way is to code a custom CExtBarTextFieldButton-derived class which implements the CalculateLayout(), PaintCompound() and OnInplaceControlCalcRect() virtual methods. Make the CalculateLayout() and PaintCompound() similar to the original ones, but reserve some space for the label and paint it. The OnInplaceControlCalcRect() virtual method should return the correct rectangle for text/combo area inside the toolbar button. You can use this combo box button in toolbars by overriding the CExtToolControlBar::OnCreateBarCommandBtn virtual method, in which your button class should be instantiated with an appropriate command identifier. If you are using customizable toolbars and menus, you should override the CExtCustomizeSite::OnCreateToolbarButton() virtual method.

We guess the text/combo button has different widths because you are using customizable toolbars and menus. Please set text/combo field width in the command tree node using the CExtCustomizeCmdTreeNode::TextFieldWidthSet() method. Please also do not forget to remove control bar and customize site state data of your program or invoke the reset command for toolbar with combo/text field to see changes.

I have found that after the call to CExtCustomizeSite::EnableCustomization(), any custom buttons I have replaced using InsertSpecButton() are changed back again.  I would like this toolbar to be customizable, but how?  Rather than inserting the custom button into the toolbar, shouldn’t I be inserting it into the CExtCmdItem somehow?

Thanks,

Rob.

You should use the CExtToolControlBar::InsertSpecButton() method only with non-customizable toolbars. The customizable toolbars and menus are based on the CExtCustomizeCmdTreeNode command tree nodes and each toolbar button and menu item should have its own command node. The initial command trees are constructed inside customize site. You can specify the command tree flags for each node and ask customize site to create appropriate toolbar buttons. If you need to create your own button classes, then you should implement the CExtToolControlBar::OnCreateBarCommandBtn() virtual method. Please take a look at the CMainFrame::OnCreate() method in the DRAWCLI sample application. It configures several command nodes near invocation of the CExtCustomizeSite::EnableCustomization() method invocation.

OK, I can see that OnCreateBarCommandBtn() works, although if I customise and create a new toolbar, then it is not of my derived type, so if I drag one of my controls onto it, it won’t draw it right.  Can I tell it to always use my class instead of the default?

Also, I found that the reason I couldn’t get text to display next to the check box (and maybe in labels too but haven’t tested that yet) is simply because the flag to always display text is not set (__ECTN_DISPLAY_TEXTONLY_ALWAYS).  But how do I set this flag?  Before EnableCustomization() there’s no CExtCustomizeCmdTreeNode for the button.  Afterwards I can set the flag, but it doesn’t take, presumably because the control is updated from the CExtCmdItem.  But I can’t see how to tell the CExtCmdItem that this item should always show text.  Any advice?

Thanks,

Rob.

If you cannot implement the OnCreateBarCommandBtn() virtual method for some of your toolbars,you can implement the CExtCustomizeSite::OnCreateToolbarButton() virtual method instead.

The __ECTN_DISPLAY_TEXTONLY_ALWAYS style can be applied using the CExtCustomizeCmdTreeNode::ModifyFlags() method. The command tree node of toolbar button is returned by the CExtBarButton::GetCmdNode() method. To update any changes of visual styles you did you should re-compute layout of toolbar’s parent frame window using the pToolbar->GetParentFrame()->RecalcLayout(); or pToolbarButton->GetBar()->GetParentFrame()->RecalcLayout(); code.

Oh, yes OnCreateToolbarButton() looks more useful.  I’m not sure why OnCreateBarCommandBtn() would ever be used instead.  I’ll try it out.

Yes, I know about ModifyFlags().  I should have asked when to set that flag rather than how, or how to make it stick.  Setting before EnableCustomization() was not possible, and setting after didn’t work.

I found a solution however.  I found CExtBarButton::OnCustomizeUpdateProps() and overrode that, using it to set the __ECTN_DISPLAY_TEXTONLY_ALWAYS flag.  At last I have text showing up for labels and check boxes!

It really is weird though that the default flags for labels are set so that text is not visible!  Took a long time to figure that out, given it was so unexpected.  Maybe you should change the default flags for labels and check-boxes, or ignore the flag and always display text anyway.

The CExtCustomizeSite class allows you to implement customizable toolbars and menus similar to that you can see in Visual Studio and some of MS Office applications. The main idea was to provide the customizable toolbars and menus with the set of basic command items, split buttons, menu trees, edit fields and combo box like fields. These set of basic UI elements should be automatically clone-able via drag-n-dropping in the customize mode and drag-n-dropping with the ALT key pressed. All the multiple copies of each element should be automatically synchronized. This is the main idea of the CExtCustomizeSite class. It’s possible to use other toolbar buttons with the customization subsystem like label buttons in toolbar, but such label buttons assumed as advanced elements and we agree they may require some improvements in the CExtCustomizeSite class.

Please add a command updating method for the button which was used for attaching a combo box control in the toolbar and enable this command. Alternatively you can add a command hander method for this button.

Toolbar buttons are controlled by MFC’s command updating mechanism. If a toolbar button has no handler/updating methods, it will be disabled. If some window is attached to a toolbar button, the window’s enabled state is automatically synchronized with the state of the toolbar button.

You should insert a CExtBarLabelButton into your toolbar near the combo box button using CExtToolControlBar::InsertSpecButton() and CExtToolControlBar::CommandToIndexMethod() allows you to determine the position of the combo box button by its command identifier.

Hi,

I’m using at my code the CExtGridWnd control, and the problem I have is that sometimes I want some of the cells to be disable in particular row when the user choose something at particular cell(meaning that cells are connected to each other), so I changed the cell’s style to read only, this works fine and the cell is truly read only but the problem is that I want it to LOOK like disable data, so the user know it’s read only, and if I only changed the style, the cell is read only, but looks the same.(user know it’s read only only when trying to type something. This problem is mainly seen in cells that are from type number or edit cells.

I will be very happy to get some help,

Thanks,

Osnat Silberberg

Hello.

I made a large icon of 32x32 for ribbonnodeLarge.

Even if I set an icon of 32x32 in RibbonNodeSmall.

Is the icon done displaying compactedly of?

If you have only a 32x32 icon, then you can create a very smoothly resized 16x16 version of this icon using highest quality resizing algorithms provided by the CExtBitmap class and not based on Win32 API. Here is the part of the CMainFrame::_InitRibbonNode_Home_Clipboard() method in the RibbonBar sample application which initializes the always big Paste ribbon button and loads the 32x32 ID_EDIT_PASTE_BIG bitmap icon into it:

. . .
CExtRibbonNode * pNodePaste =
                        new CExtRibbonNode( ID_EDIT_PASTE, 0, NULL, 0, _T("Paste") );
            pNodePaste->CmdKeyTipSet( new CExtCustomizeCmdKeyTip( __EXT_MFC_SAFE_TCHAR( _T(’V’) ) ), false );
            pNodePaste->RibbonILE_RuleArrayGet().RemoveAll();
            VERIFY( pNodePaste->m_iconBig.m_bmpNormal.LoadBMP_Resource( MAKEINTRESOURCE(ID_EDIT_PASTE_BIG) ) );
            pNodePaste->m_iconBig.m_bmpNormal.Make32();
            pNodePaste->m_iconBig.m_bmpNormal.AlphaColor( RGB(255,0,255), RGB(0,0,0), 0 );
                                                                                    pCmdScreenTip = new CExtCustomizeCmdScreenTip;
                                                                                    pCmdScreenTip->CaptionMainSet( _T("Paste") );
                                                                                    pCmdScreenTip->TextMainSet( _T("Paste the contents\nof the Clipboard.") );
                                                                                    pCmdScreenTip->BmpMainGet().LoadBMP_Resource( MAKEINTRESOURCE(ID_EDIT_PASTE_BIG) );

                        );

For ribbon buttons use 16x16 icons in small layout without text and normal layout with text on right. The 32x32 icons are used only in the large layout with text at bottom. If you need something else, you should use custom ribbon button and ribbon node classes.
