How can I scroll an entire tab right or left when clicking the right and left scroll buttons on the mid tabs.
Currently, it scrolls some small number of pixles.

Yes, you are right. We changed our code as you suggested. Thank you.

You should apply the __ETWS_SCROLL_BY_PAGE tab window style by using the CExtTabWnd::ModifyTabWndStyle() method.

OK I tired that and I couldn’t get it to work.

Correctly, the code hit the CExtTabWnd::OnTimer with a scroll value of m_nScrollDirectionRest=301 that should have ontimer continue until
nScrollDirectionRest reached zero at which the timer is killed.


But, then for some reason immediately

void CExtTabWnd::OnCancelMode()
{
    CWnd::OnCancelMode();

    if( m_nScrollDirectionRest != 0 )
    {
        m_nScrollDirectionRest = 0;
        KillTimer( __EXTTAB_SCROLL_TIMER_ID );
    }

    OnTabWndMouseTrackingPushedStop( true );
    OnTabWndMouseTrackingHoverStop( true );
}




is called, ( I didn’t do it) and the timer is killed and does not complete the entire scroll for the whole tab.

Is it possible to set the indent of CExtTreeGrid items?

Thanks, Dave

When I close the controlbar using the "X" (close) button, then by default it opens up... on ShowControlBar(SW_SHOW). This I dont want, I want the user to open it from a menu option only if the "X" has been pressed as that means that the user doesnt want the controlbar at all and not just hide it to resurface again....

Can I handle the "X" of a CExtToolControlBar. Please suggest as its very urgent.

Hi,

This is my current implementation. I want to call the OnNcAreaClicked() method when i close the control bar.

class CSaControlToolBar : public CExtToolControlBar
{
public:
// Construction
CSaControlToolBar();
virtual void OnNcAreaButtonsReinitialize()
{
     CExtToolControlBar::OnNcAreaButtonsReinitialize();
    
}
virtual CExtBarNcAreaButtonClose OnNcAreaClicked()
{
        AfxMessageBox("Hi");
        
        return NULL;
    }

};
Can you please help me regarding this.

This might work, though I didn’t try:

class CSaControlToolBar : public CExtToolControlBar
{
	class CSaBarNcAreaButtonClose : public CExtBarNcAreaButtonClose
	{
	public:
		CSaBarNcAreaButtonClose(CExtControlBar * pBar) : CExtBarNcAreaButtonClose( pBar ) {}
		virtual bool OnNcAreaClicked( CPoint point )
		{
			AfxMessageBox("Hi");
			return CExtBarNcAreaButtonClose::OnNcAreaClicked(point);
		}
	}; // class CSaBarNcAreaButtonClose
	virtual void OnNcAreaButtonsReinitialize()
	{
		ASSERT_VALID( this );
	INT nCountOfNcButtons = NcButtons_GetCount();
		if( nCountOfNcButtons > 0 )
			return;
		NcButtons_Add( new CSaBarNcAreaButtonClose(this) );
	#if (!defined __EXT_MFC_NO_TAB_CONTROLBARS)
		NcButtons_Add( new CExtBarNcAreaButtonAutoHide(this) );
	#endif
		NcButtons_Add( new CExtBarNcAreaButtonMenu(this) );
	}
}; // class CSaControlToolBar

Dear Support,

I’ve experienced some painting problem in our grid, and I could successfully reproduce it in your ProfUIS_Controls sample. Please, open your PageGrid.cpp. In OnInitDialog, comment the line m_wndGrid.GridLinesHorzSet( true, bRedraw ); ( I don’t want to show any gridlines, but to reproduce the problem, removing horizontal gridlines is enough ) and in SiwModifyStyle call, change __EGBS_SFB_CELLS style to __EGBS_SFB_FULL_ROWS style ( I need to achieve fullrow selection ).

With these 2 changes the focus rect around the focused row is somehow thicker than before. This wouldn’t be a problem, but if the user opens any popup control from the grid ( e.g. color selection control or listbox of a combobox cell), the focus rect gets partially hidden by this control and when the popup control gets closed, the part of the focus rect (which was painted over by the popup control) is not repainted.

Unfortunately I can’t provide a picture now, I hope you understand, or at least can reproduce the problem.

Thank you,
Chris

How do I get a grid to select a cell on a right click?

Thanks, that worked

What should be the default CWnd* parameter in CExtTabPagecontainerWnd.PageInsert(CWnd*). I have a CView called PresView and I write the following:
m_pChildView->PageInsert (m_pPresView->GetSafeHwnd(),_T("Name"));

This process gets repeated gain when i need to add another tab. But now the catch is.... the first tab which was created over the PresView is over wriiten by the tab that was created later. The first tab physically exists but the view which should be associated with it gets overrritten by the latest tab. Do you hav any resolution to this..

Can we have a default CWnd* paranmeter

Please suggest

You can create a view window using the following code:

CWnd * pParentWindow = . . . // tab page container in your project
CCreateContext _cc;
      _cc.m_pCurrentDoc = NULL;
      _cc.m_pCurrentFrame = pParentWindow;
      _cc.m_pLastView = NULL;
      _cc.m_pNewDocTemplate = NULL;
      _cc.m_pNewViewClass = RUNTIME_CLASS( CYourView );
CWnd * pWndView = CreateView( &_cc );
      if( pWndView == NULL )
      {
            TRACE0("Failed to create your view window\n");
            return . . . 
      }
CYourView * pView = STATIC_DOWNCAST( CYourView, pWndView );

As we discussed in the call with Sergiy, the same window cannot be used to load more than on Page ContainerWnd.
Now I am creating new windows for separate tabpagecontainer windows.
But do you have any idea that how can I create a copy of one CView on new windows that I am creating.?
Becoz at the end what i want to achieve is show the different versions same view on different windows . I can manage to activate the different versions but not able to create views that can show them.

Yes, if your connection is fast enough, that would be much easier to find what’s wrong by sharing your desktop.

What we need to implement is --

We want to dynamically add tabs at runtime by user action .There is a Mainframe on which I already have 3 tabpage containers representing 3 views. Out of these 3 views the last one is called PresView. Now if I add new tabs with the line
m_pChildView->PageInsert (m_pPresView->GetSafeHwnd(),_T("Name"));

For every new entry of tab... at runtime, then the PresView gets updated by the last page and all exisitng pages are overwritten.


I think we should go for a desktop sharing as it could help us mitigate the problem faster. Can we schedule it as soon as possible as it is very very urgent. I will be sending you a mail request for this from my id. Sanket_das1@yahoo.co.in

Hi,

I want to handle events on Autohide button of contorlbar how can we do this?

If I can, would you please tell me how?

I have a window in my application which is a CExtToolBoxWnd, and I want to load a tree control derived from CTreeCtrl on it.
I have a specific hirerchy in my tree structure and I want to retain the hirerchy.Kindly provide me some concrete way on it..

Will I be able to use features of ToolBox window like collapse and expand and highlight on mouse hover.?

Any sample application would of good help.

Sorry, forgot to provide a link to the sample. Here it is:

SDIDOCVIEW.zip

Here is a modified version of the SDIDOCVIEW sample in which there are two control bars: one with tree controls and another one with a toolbox. At the application initialization in the CMainFrame::OnCreate() method, we invoke a DuplicateTreeInToolbox() method which creates the toolbox items with the same hierarchy as in the tree control. This is done in the _WalkTreeChildBranch() recursive function.

It would be very helpful, if u can give us a sample

Dear Support,

I have a grid which is sorted.
When new rows are added to the grid, I would like them to be added at the correct location according to the sorting order (the user clicks column header to set the sort order - default behavior).

What I do, is add the new rows at the bottom of the grid, and then I want to re-sort it according to the current sort column and order.

I read the FAQ about this GridSortOrderSetup function, but I need to know what is the current sort column and order, and I have no idea how to extract this data from my grid.

You should not remove DYNAMIC_DOWNCAST but you can replace it with STATIC_DOWNCAST if you are sure all the cells in the column are of the the same type. If STATIC_DOWNCAST generates assertions, your grid cell’s code is not safe. We believe STATIC_DOWNCAST will raise assertions. The grid cell classes require DECLARE_SERIAL and IMPLEMENT_SERIAL instead of DECLARE_DYNCREATE and IMPLEMENT_DYNCREATE. This should be the main problem with your short version of grid cell class.

We have just checked your class by using Prof-UIS_Controls sample ans found out that the Compare method is called and the other cell after downcasting had the valid type CExtGridCellReadOnlyNumber. So, we cannot confirm this problem. Would you reproduce the problem using any of our sample and send it to us?

Dear Support,

I removed the DYNAMIC_DOWNCAST and it seems to work fine.
I guess the problem lies somewhere in this piece of code:

	CExtGridCellReadOnlyNumber * pCell =
		DYNAMIC_DOWNCAST(
		CExtGridCellReadOnlyNumber,
		( const_cast < CExtGridCell * > ( &other ) )
		);

CExtGridCellReadOnlyNumber * pCell = (CExtGridCellReadOnlyNumber*)(&other)

You can get information about the current sorting using the CExtGridWnd::GridSortOrderGet() method. But it seems you do not need this method. You should simply invoke the following code after adding one or more new rows/columns at any location inside the grid:

CExtGridWnd & wndGrid = . . .
CExtGridDataProvider & _DataProvider = wndGrid.OnGridQueryDataProvider();
      _DataProvider.SortOrderUpdate( true, &wndGrid );
      _DataProvider.SortOrderUpdate( false, &wndGrid );

Thanks - problem solved...

I have another problem with sorting - I need to sort some columns accoring to their integer value, and not the default lexicographic sorting.
How can I add my custom/integer sorting to a column?

Regards,
Ron.

When data is sorted in the grid, the CExtGridCell::Compare() virtual method is called in order to compare each cell pair in each sorted column. Please note that different cell classes have different implementations of this method. We guess you are using some simple text cell class like CExtGridCellString in the column with numeric data. It seems you should use some other cell type for this column (e.g. CExtGridCellNumber).

Dear Support,

I format my text (number) in a very specific way i add comma, and unit, so using CExtGridCellNumber is not a good option for me.
If I understand correctly, I should derive my cell, say CExtCellRange, which will hold the number I need to compare, and add the virtual Compare function?

Your grid cell class may look like as follows:

Hi,

I need to load a png file in a CExtToolControlBar.
I have included ProfSkin.h as a header and used CExtSkinBitmap to upload that png file.
I have taken help from the code snippet given below.

LPCTSTR strPngImageResourceID = MAKEINTRESOURCE( IDR_PNG_RESOURCE_IMAGE );
LPCTSTR strPngResourceSection = _T("PNG");
HINSTANCE hInst = AfxFindResourceHandle( strPngImageResourceID, strPngResourceSection );
ASSERT( hInst );
HRSRC hRsrc = FindResourceHandle( hInst, strPngImageResourceID, strPngResourceSection );
ASSERT( hRsrc );
VERIFY( _bmpTmp.LoadPNG_Resource( hInst, hRsrc ) );

Here, I got an error in the FindResourceHandle method. The Message is "’FindResourceHandle’: identifier not found".

Can you help me to upload the png file into the CExtToolControlBar?

Sorry, I gave you a wrong answer in the previous post. You should use
HRSRC hRsrc = ::FindResource( hInst, strPngImageResourceID, strPngResourceSection );

hi there,

I have a question about the theme change event. Our app caches system colors during the startup ( by calling g_PaintManager->GetColor()), when the theme is changed, we have to update the cache colors. From the FAQ, one approach is to derive from CExtPmBridge, and overwrite the PmBridge_OnPaintManagerChanged() method.

Normally should this be done with an existing class, like the main frame wnd, or a global class which live through the life span of the app. I guess once the object is deleted, I will lose track of the event?

Any other light weight approach, like a callback function ?

Thanks

it works, thank you

Dear Support,

Our application’s main structure is similar to your SimpleGrids sample. It seems to me that the font used in the grid is different from the font used on the tabs of the TabPageContainer, even though no code in our application (or in SimpleGrids application) changes the font. Shouldn’t all ProfUIS controls use the same default font? If not, what was the reason you chose another font for either the grid or the tabs? What code should we add to our application to have the same font used in both controls?

Thank you!
Chris

There is a g_PaintManager->m_FontNormal stored in the global paint manager, which controls the font used In most of Prof-UIS controls. But some Prof-UIS controls when placed on a dialog use the parent dialog’s font. In the latter case, you can assign a custom font using the CWnd::SetFont() method.

As I wrote in the first post, these controls are not on a dialog. Just start your SimpleGrids sample (which is not dialog based application) and check out the fonts used in the grids and on the tabs of the TabPageContainer. They are different. So at least one of them is not using g_PaintManager->m_FontNormal. Which of them should I change and how to produce the same fonts? (I’d prefer the font used on the tab items but if you could show me the other way around, as well, it’d be great)

BTW, regarding your answer: when a grid is placed on a dialog, the font used in the grid is not the same as on the dialog. I need to call m_wndGrid->SetFont(GetFont(), false); manually in OnInitDialog.

Best regards,
Chris

Hello!

I’m trying to open FileOpen and FileSave common dialog looks like all application style (CExtPaintManagerOffice2007_Black).

I try to subclass FileOpen dialog:

class CProfUISFileDialog : public CExtNCW<CExtResizableDialog>

        m_bShowResizingGripper = false;
    }

    virtual ~CProfUISFileDialog() {}

        // Test Opening
        OPENFILENAME ofn; // common dialog box structure
        TCHAR szFile[MAX_PATH]; // buffer for file name

        if (GetOpenFileName(&ofn)==TRUE)
        {

        }
        return IDOK;
    }
private:
    CWnd* m_pParent;
};

and use by

CProfUISFileDialog dlg(this);
dlg.DoModal();

But this solution crashed... at

void CExtComboBoxBase::DrawItem( LPDRAWITEMSTRUCT lpDIS )
{
...
if( lpDIS->itemID >= 0 )
        {

...

}

Help me to solve this problem or please send me sample how to create CFileDialog in same style as other application.

How can I handle the right click on a tab item in a CExtTabWnd tabstrip. I suppose theres no overridable method to accomplish this.
I want to display a pop-up context menu on right clciking the items on the tabstrip.

How can that be done and where exactly the message maps need to be inserted i.e. for the mainframe class or the tabwnd class etc.Please suggest. Can you just give me a skeletal method /sample for it.

Thanks.

Hello.

Please teach it if you like.
Prof-UIS is an irrelevant topic.

I cannot acquire minimization button size well.
In "SM_CXSIZE, SM_CYSIZE", numerical value of 18*18 returns.

Hello

I can seem to cope in SM_CXSIZE ,SM_CYSIZE somehow.
Thank you.

Dear Support,

We had a discussion in the past regarding how to implement a custom cell, including in the in-place edit part.
I are now in a real need for such tutorial, please try and give this task a higher priority.

Thanks in advance,
Ron.

The article will be ready soon. We are sorry for the delay.

We can create such a tutorial right away. But could you give us some clues about some kind of cell and in-place editor that you will be using in your project? We would then use it as an example in this tutorial.

I sent you a link via mail.
Please let me know if you got it.

Yes, we did. Thank you. We will prepare and publish the article in the next week.

Dear Support,

Any news? still waiting for this tutorial...

Regards,
Ron.

How can I disable the report grid group area so the groupings can not be changed? My app sets the grouping, and I don’t want the user to be able to change it, but I do need the display so the user knows what the grouping is.

I would like to keep the sorting enabled within the group area.

The tab strip in my application vanishes if the application is left unused for some time. I find no way of retrieving it. Its just gone... vanished..
What should be done?


Thnx

Ya .. we can go ahead with a desktop sharing session. A mail would be sent to you from my ID today.

Actually I find the tabstrip hidden once i minimize my application. So this seems to be a repaint issue.
How to handle that?

Unfortunately we cannot say what what may be wrong in your application without seeing the source code. There are several ways we can help you. You can create a test project and send it to us. You can modify one of our samples so that the problem can be demonstrated with it. Finally, we can help you debug the problem remotely if your connection is fast enough.

There is not enough information to find out what could be the problem. Have you tried what Support suggested, have you used SPY++ to see what messages the tab receives around the time it disappears?

I know you think that desktop sharing is time consuming, but it is really much-much more time consuming this way, as the information you share is not really helpful in solving the problem. You should reconsider Support’s offer about desktop sharing.

Actually I find the tabstrip hidden once i minimize my application. So this seems to be a repaint issue.
How to handle that?

The CExtTabWnd class is used to create a tab strip. This tab strip object has been used to create tabs and they are working fine.But if ileave my applicatioon open for say 30-45 mins the tab strip gets vanished altogather and doesnot come back on click,dblclick or mouse over.

The tabstrip is gone totally.

Can u give som pointers?

We have never encountered this problem in our samples nor anybody reported such a problem earlier. We suspect you may have some code in your application that causes this problem. What we can suggest is to watch for all the messages for the tab window using the SPY++ utility. We wonder which messages are displayed in SPY++ after this 45 minutes delay?

I do not display the toolbar in PropertyGrid controls in my app. I only show the sort by category display. As such there is no need for the sorted property display. Can I safely override OnPgcCreateGrids() and NOT create it without problems?

Thanks
