Hi!
I am writing an MDI app using CExtTabMdiWhidbeyWnd
I just face 3 problems (one bigger than the others):

- Why the size of the document is not stored? for instance, if I open a new MDI doc, maximize it, close it, then open another new document, the new one will appear windowed and not maximized.
is there anything I can do, or do I have to implement this "memory" mechanics by myself?

- when I open many document and maximize them, and when I use the tabs to switch from one to another, I can see clearly the "soon to be the active doc" in a windowed state before it is displayed as maximized. Of course, it’s short, but it is really bothering. (this is my bigger problem)

- is there an automated way to hide the tabs when the MDI docs are displayed in a windowed mode?

Actually, I could solve the first and the third problem by myself, but i am quite stucked by the 2nd.

Best regards,

Raph

I am developing an application which has a dialog. On that dialog, I created a tab container. This tab container has two tabs. One has the tree control (CExtWFF<CTreeCtrl>) on it. The dialog box is not getting any notification message (like TVN_SELCHANGED, NM_CLICK) from the tree control. If I use the tree control directly on the dialog then it works. Could you please suggest any solution. Is it a problem? is there any other way of doing. Here is an example how I am using. Please let me know what is wrong.

Thanks.

Hi:
I’m very new to Prof-UIS (like this week!). I’m trying to convert an existing application to use Prof-UIS. I’ve got the tabbed windows working for my MDI Clients. Before any documents are opened, how do I paint the background of the clients? e.g. how do I make the "interior" of the Mainframe show up a company logo? I have taken a look at the TabbedBars example and it is quite overwhelming. I don’t need the bitmap to be consistent across toolbars, or work with any theme, etc. -- just to show up! The bitmap should be tiled.

I have implemented the OnMsgPaintInheritedBackground registered message in my CMDIChildWnd class -- but since it is never even called I’m clearly doing something wrong. Please, can you start from the beginning on changing my CMDIChildWnd class and pretend I’m an idiot? Many thanks.

Is there a wrapper class for CListView and CTreeView to give them proper look and feel?

Thanks,

Hello

Is there a notification message when the autohide pin is pinned or unpinned?

Thank you

Thomas

Please create a CExtControlBar-derived class and override AutoHideModeSet() virtual method in it. This method turns on/off the auto-hide mode for the control bar. Do not forget to invoke the base class’s method.

Hello

I noticed that by selecting/activating certain MDI tabs the order of the tabs is not left->right anymore. In the following screenshot

http://www.ierax.ch/download/taborder.jpg

If I press Ctrl-Tab the order is a.tif->c.tif->d.tif->b.tif->a.tif... instead of a->b->c->d

Why does this happen? Can I prevent this?

Thanks in advance

Thomas

Actually we do not change the default behavior of the Ctrl+Tab key. We just handle the WM_MDIACTIVATE message to synchronize the active child widow with currently selected tab item. So this is standard behavior of the MDI application.

Thank you for your answer. Of course you are right, I came to the same conclusion when I thought about it. Pressing Ctrl-Tab twice should get you back to the original document and so this order has to be modified.

However, in our scenario we would be glad if we could get our hands onto the physical list of mdi tabs. If I have a tab is there an easy way to find out which tab lies left/right of it? Or do I have to maintain this list myself?

You can override the WindowProc() virtual method and handle the Ctrl+Tab click event to implement custom window switching. Just get an index of the currently selected tab using the SelectionGet() method, increase the index, and activate the next tab using the SelectionSet() method.

Please note that each tab item has an HWND handle associated with it. This handle is a window handle of the child frame window. You can retrieve this handle with the ItemLParamGet() method.

Hi, is possible to draw the text of a CExtButton vertically?

Is there any simple way to add a png picture tool a toolbar button and also a menu item?
Any source code to how to do this?

Ok how much more easy quetion can i ask how to you change tooltips for toolbar and menu so they are balloon tooltips?

You need to override the CExtControlBar::OnAdvancedPopupMenuTipWndDisplay() method in this way:

void CYourToolbar::OnAdvancedPopupMenuTipWndDisplay(

            CExtPopupMenuTipWnd & _ATTW,

            const RECT & rcExcludeArea,

            __EXT_MFC_SAFE_LPCTSTR strTipText

            ) const

{

            ASSERT_VALID( this );

            ASSERT( strTipText != NULL && _tcslen( strTipText ) > 0 );

            _ATTW.SetTipStyle( CExtPopupMenuTipWnd::__ETS_BALLOON );

            _ATTW.SetText( strTipText );

            _ATTW.Show( (CWnd*)this, rcExcludeArea );

}

Hi,

I am trying to use a CExtGridWnd.
I need to allow my users to add, remove and insert rows and columns. All the cells are text based, and all must be editable

while it works quite well when adding or removing, all the inserted cells are read only. the only exception is the header cell when i insert columns.
I used exactly the same code to add and to insert, but adding will create editable cells, unlike inserting.

does anyone have an idea about this?

regards,
Raph

We need to take a look at your code so that we can find out what is wrong. You can send us either a piece of code or the entire project.

Please note that to make the cell editable, you need to remove the __EGCS_READ_ONLY and __EGCS_NO_INPLACE_CONTROL cell styles. Of course, the grid should have the __EGWS_BSE_EDIT_CELLS_INNER style applied.

1) In OnPaint method, of CForm view derived class, I have g_PaintManager->PaintDocumentClientAreaBkgnd( dcPaint, this ), the windows in not paint correctly when I scroll it.

2) I have inserted CTreeCtrl derived class in CExtControlBar, I’m not able to display icon and, when I compile in release, I don’t see mouse during movement.

Coult you have any suggestions?

tx a lot

1) The g_PaintManager->PaintDocumentClientAreaBkgnd() method doesn’t support scrolling.

2) It is not completely clear what the problem is. Which icon is not displayed? Would you send us some screenshot(s) or a test project?

HI, I solved the problem about icon in CTreeCtrl, was my problem.

The problem of the mouse persist and I not understand why. I’m using VC8 - ProfUIS 2.5.4. I have a CTreeCtrl*** inside of CExtControlBar.
If I start my exe inside of VC, the mouse is display correctly (when is over CTreeCtrl), indipendently if I compile in Debug or in Release. If I start the program outside af VC (double click on exe icon), the mouse in not displayed when is over CTreeCtrl. Have you experience of similar error in ProfUIS?
Unfortunately I cannot send you my proyect because is very big and it has integration with database and other object.


***
I have created CTreeCtrl as a child window of CWnd derived class, this class is created as child of CExtControlBar.

I appreciate any help.

Tx a lot

No, we have never encountered the similar problems before and no our customers reported about these problems. We have several samples in Prof-UIS and they are working correctly. Would you try to create a small project and reproduce the problem?

I seen g_PaintManager->PaintDocumentClientAreaBkgnd() method doesn’t support scrolling. There is a method I can use to implement it?

Hi,
I’m using a CExtStatusControlBar status bar and the Office 2007 (Luna-Blue) theme.
The gradient on the first pane ("Ready" text) is a light blue and all the other panes have a dark blue gradient.

Is there a way to make the rest of the panes have the same gradient as the first pane?

Thanks,

John Kiernan

Yes, you can set any of two backgrounds for the status pane when Office 2007 themes are applied. All the supported status pane backgrounds are defined by the CExtStatusControlBar::e_StatusPaneBackgroundAccent_t enumeration:

    enum e_StatusPaneBackgroundAccent_t
    {
        __ESPBA_AUTOMATIC    = 0,
        __ESPBA_LIGHT        = 1,
        __ESPBA_DARK         = 2,
    };

    int GetPaneCount() const; 
    virtual e_StatusPaneBackgroundAccent_t OnQueryPaneBackgroundAccent(
        int nIndex
        ) const;
    e_StatusPaneBackgroundAccent_t GetPaneBackgroundAccent(
        int nIndex
        ) const;

Alright, now I have a related question. I just made my dialog resizable and now the gripper on the status bar has a dark accent.
Is there a way to change the gripper background accent to be light also?

Thank you for the interesting question. We would like to ask you to update the source code for the CExtPaintManagerOffice2007_Impl::StatusBar_EraseBackground() method in the ../Prof-UIS/Src/ExtPaintManager.cpp file. This update will make the gripper consistent with the background style of the last status pane:

bool CExtPaintManagerOffice2007_Impl::StatusBar_EraseBackground(
    CDC & dc,
    const RECT & rcClient,
    const CExtStatusControlBar * pStatusBar,
    LPARAM lParam
    ) const
{
    ASSERT_VALID( this );
    ASSERT_VALID( pStatusBar );
    lParam;
    if(    m_bmpStatusBkLight.IsEmpty()
        || m_bmpStatusBkDark.IsEmpty()
        )
        return false;
bool bLastIsDark = true;
INT nPaneIdx, nPaneCount = pStatusBar->GetPaneCount();
    if( nPaneCount > 0 )
    {
        CExtStatusControlBar::e_StatusPaneBackgroundAccent_t eSPBA =
            pStatusBar->OnQueryPaneBackgroundAccent( nPaneCount - 1 );
        if( eSPBA == CExtStatusControlBar::__ESPBA_LIGHT )
            bLastIsDark = false;
    }
    if( bLastIsDark )

            CExtBitmap::__EDM_STRETCH
            );
    for( nPaneIdx = 0; nPaneIdx < nPaneCount; nPaneIdx++ )
    {
        CExtStatusControlBar::e_StatusPaneBackgroundAccent_t eSPBA =
            pStatusBar->OnQueryPaneBackgroundAccent( nPaneIdx );

Excellent. Works great!
Thank you very much for your time.

THERE SHOULD BE A METHOD TO CALL TO CHANGE THE TOOLBAR BACKGROUND

Prof-UIS supports 9 built-in UI themes and skins. There is little point in using the term "background color for toolbar" independently from other ui elements. Although you can colorize some controls for some theme (e.g. as it is shown in the ThemeColorizer sample), it is not possible to colorize the toolbar universally for any given theme unless you paint the toolbar window’s background manually yourself.

If a right mouse click is applied to a button on the toolbar derived from CExtToolControlBar a popmenu appear, how does on disable that.

Have you received our reply with the project attached by e-mail? We described how to remove and/or modify any built-in Prof-UIS menu in it.

THE CODE YOU SENT NEVER WORKED , IF I APPLY A RIGHT MOUSE CLICK ON A TOOLBAR BUTTON THE POP UP MENU APPEARS

I want a Toolbar that is not Dock.

Hi,

I have noticed that each time that a sub-menu is opened (even of the menu bar - a top level menu), a thread is created and exits.
Why is this? how can I remove this?

I had some weird hang-ups when opening menus in my application, which is heavily multi-threaded, and i think it has to do with this thread.

Thanks.

We have just posted a FAQ How to customize or disable sounds used in pop-up menus?, which covers what you are looking for.

Use the SND_ASYNC flag, for example:

    PlaySound("MailBeep", NULL, SND_ALIAS|SND_ASYNC);

This should remove the need to create a thread.

For consistency reasons, in my project I need to create icons from bitmaps found in toolbars. A couple of years ago, you helped me with the following function:

int
iGetIconFromToolbar( int iToolbarId, int iBitmapIx, CExtCmdIcon& rIcon)
{
// Recover the bitmap list
HBITMAP hBmp = CExtPaintManager::stat_LoadBitmapResource(
MAKEINTRESOURCE( iToolbarId ) );

ASSERT( hBmp != NULL );
BITMAP bmpInfo;
::memset( &bmpInfo, 0, sizeof(BITMAP) );
::GetObject( hBmp, sizeof(BITMAP), &bmpInfo );
ASSERT( bmpInfo.bmWidth > 0 && bmpInfo.bmHeight > 0 );

INT i = iBitmapIx;
CRect rcPart( 16*i, 0, 16*(i+1), bmpInfo.bmHeight );

// original version
// rIcon = CExtCmdIcon ( hBmp, RGB(0,255,0), &rcPart );

// new version

rIcon.AssignFromHBITMAP(
hBmp,
RGB(192,192,192), // COLORREF(-1L) - no force transparent pixels
&rcPart        );

ASSERT( !rIcon.IsEmpty() );
::DeleteObject( hBmp );
return 0;
}


While upgrading to Professional Studio 2.54 I noticed some interface changes in CExtCmdIcon (e.g. there was no constructor taking a bitmap as an argument; I used instead the member function CExtCmdIcon::AssignFromHBITMAP() ).
In the new implementation though, the background is transparent only if the color quality of the display is 32 bit. Whenever the color quality of the display is 16 bit, the icon’s background is no longer transparent. This is an issue if the application is run through Windows Remote Desktop where the color quality of the display is 16 bit.

I sent you a modified version of the file MainFrm.cpp belonging to the project PageNavigator. Rebuilt the project with it and run it twice:
- first set Display/Settings/Color quality to 32 bit everything; notice the question mark associated to the E-mail button has a transparent background (as it should)
- stop the application and change Display/Settings/Color quality to 16 bit.
- rerun PageNavigator: you’ll notice the background of the E-mail button is no longer transparent...


Thanks,
Emil

I AM USING THE CExtToolControlBar FOR A TOOLBAR AND I NEED TO CHANGE THE BACKGROUND OF JUST THE TOOLBAR ON THE FLY. ANYONE GOT THE CODE TO DO THIS

Geeze here is another pas one has to search
How does one get the state of a button on a toolbar derived from CExtControlBar since CExtControlBar is not derived from CToolbar?
