Dear Support,

As you are already painting the combo-box yourself - can you please add item color support like in the combo-box cell?

Thanks,
Ron.

How about the flicker were you able to fix this bug for 2.83?

Dear Support,

Thanks. However there are terrible flicker problems now with this combo - as I reported in the past. Were you able to fix this for the coming version?
Also - is it possible to add an icon in this cells? I could not see any such function.

Thanks,
Ron.

When loading a saved UI state, there is a bug with the visibility of floating bars that occurs in some situations. Follow these steps exactly to reproduce the problem using the StateInFile sample:

- Delete HKEY_CURRENT_USER\Software\Foss\StateInFile to get a fresh start.
- Run the StateInFile sample (Unicode Release, VS 7.1)
- Dock bar 0 to bottom with bar 1 (tabbed)
- Make sure bar 1 visible in the tabs
- Save to a file called "state1"
- Undock bar 0 so that it becomes floating.
- Save to a file called "state2"
- Load file "state1"
- Load file "state2"

At this point, bar 1 is docked at the bottom and bar 0 is no where to be found. Bar 0 should have been floating and visible.

Its been a little over a month since I reported this problem and still have no reply. Has this problem been fixed? Is anyone looking into it?

Hello support team,
I’d like to ask if it’s possible to use more than one paint manager at the same time?
Example: Use the CExtPaintManagerStudio2008 in general and the CExtPaintManagerNativeXP for CExtButtons to have the buttons in the ’normal’ XP style.
Thanks

Dear support,
I would like to skin my interface using the Themes of Prof-UI, I am fine with painting most of the non client region , but when I add a splitter window to an SDI application the splitter window`s separator still appears to be painted in the classical MFC way. How to make it get applied with the theme given by Prof-UIs themes,

Also give me an idea how can i attach screen shots of the problem i am facing with the application with the query.

Thanks,
Raghavendra

In several previous postings it has been stated that one can use CExtControlBar::_CalcDesiredMinVH() and the CExtControlBar::_CalcDesiredMinHW() methods to set the minimum size of the control bars. I have been experimenting with these virtual functions as well as _CalcDesiredMinFloatedSize and am confused as to just what they do and how they interact.

The function _CalcDesiredMinFloatedSize seems to control the minimum size while floating, unless one of the other functions returns a value that is larger than the dimension returned in _CalcDesiredMinFloatedSize. Also it seems that ...MinHW controls both the width and height of a window that can be docked on all four corners while ...MinVH has some impact as well but seeming not as separate horizontal vs. vertical inputs. Can you please supply a summary of what each of these functions are supposed to do?

Thanks

Hi,
I am facing a problem using a CExtPropertyGridCtrl.
I am using the PropertyStore as a dynamic container. It means I add and remove properties.
I’m trying to restore the selection.

I did a sample to illustrate how I use your component and to help you to solve my issue.
(http://aurelien.loizeau.free.fr/profuis/PropertyGridSample.rar)

To make it crash, use it as following:
1. Launch the sample :)
2. Select the last property
3. Click the remove button
4. Select a property -> Throwes an assert

I tried many things to solve this problem, but I failed.
I hope you will solve it easily.

ps: Will you have a attach feature in your support forum soon ?

Great, the problem is gone.
Thanks.

We tried to reproduce the crash with the latest code (we are working on) but failed. Would you download the latest code from our ftp site and let us know if the problem is gone? Please drop us an email if you don’t know the download details.

Dear Support,

I see that RowHide is not implemented for trees.
How can I hide a row in a tree then?

Thanks,
Ron.

Dear Support,

I see that a CExtTreeGridWnd has function to hide a specific row - RowHide, but there is no RowUnHide to a specific row, only RowUnHideAll.
Am I missing something?

Regards,
Ron.

Hi, i trying to create RTF inplace editor
I create
MyRTFEditor derived from CRichEditCtrl with context menu and
MyRTFCell derived from CExtGridCell
Than i override
MyRTFCell::OnInplaceControlCreate(...)
{
retrun CreateRTFEditor();
}
It’s working normally.
If I make right mouse click on activated MyRTFEditor my context menu show but focus sets to GridWnd and I lost focus on my MyRTFEditor.
I try to override
MyRTFCell::OnInplaceControlWindowProc() and
MyRTFCell::OnInplaceControlPreTranslateMessage() but they never call.
What I do wrong ?

Hello there Phillip,

I am facing a similar problem - can you explain what was your solution?

Thanks,
Ron.

HI
I have a dialog derived from
class CDlgForex : public CExtNCW <CExtResizableDialog>
what I want to achieve is to make its background black. I tried to write such code

BOOL CDlgForex::OnEraseBkgnd(CDC* pDC)
{
CRect rc;
GetClientRect(&rc);
pDC->FillRect(&rc, &m_brush);
return TRUE;

//return CExtNCW<CExtResizableDialog>::OnEraseBkgnd(pDC);
}
HBRUSH CDlgForex::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CExtNCW<CExtResizableDialog>::OnCtlColor(pDC, pWnd, nCtlColor);

pDC->SetBkColor(RGB(0, 0, 0));

// TODO: Return a different brush if the default is not desired

return (HBRUSH)m_brush;
}


where
CBrush m_brush;
m_brush.CreateSolidBrush(RGB(0, 0, 0));

but with no luck, background is always drawn with the color for currently selected UI theme.

What would be the steps to achieve this goal?

Thx

Dear Support,

I have a cell with a check box text and button.
I would like that when the check-box is unchecked, the text will appear read-only and the button will be disabled.

Can this be done? If yes, can you please explain, if not, can this feature be added to next releases?

Thanks,
Ron.

We have just checked our implementation of the check box and came to a conclusion that you should not apply the __EGCS_READ_ONLY style if you want to leave the check box enabled and clickable. Instead, apply the __EGCS_NO_INPLACE_CONTROL cell style in the CMyGridCell::OnSetCheck() method , set the cell’s text color to COLOR_3DSHADOW and make the button disabled.

You can control if a cell button is enabled or disabled by overriding CExtGridCell::OnQueryButtonInfo()

virtual bool OnQueryButtonInfo(
    INT nButtonType,
    bool * p_bEnabled,
    bool * p_bPressed = NULL,
    bool * p_bStayPressed = NULL,
    UINT * p_nTimerElapseValue = NULL
    ) const;

Wouldn’t this make the check-box disabled as well?
I want the check-box to remain enabled even when it is un-checked.

Dear Support,

I would like to display a tootlip, but I don’t want it to be automatically hidden, on timeout or on any other default mouse/keyboard inputs.
I could not find a way how to force the tooltip to be displayed.
What I eventually did is derive mo class from CExtPopupMenuTipWnd, and added these two function:

	virtual void Hide() {}
	virtual void ForceHide() { CExtPopupMenuTipWnd::Hide(); }

Anybody...? Please...

Maybe today?

Dear Support,

I need to display two buttons in one cell, and change their appearance.
I know how to do it with one (I add __EGCS_BUTTON_ELLIPSIS and in OnPaintButton I set __EGCPF_NO_BUTTON_ELLIPSIS_DOTS)
I added __EGCS_BUTTON_DROPDOWN, but I faced the glyph removal problem - I couldn’t find a matching __EGCPF_NO_BUTTON_XXX flag

I looked into and I see this code:

...
	if( nButtonType == INT(__EBTT_DROPDOWN) )
		pGlyph = 
			CExtPaintManager::g_DockingCaptionGlyphs[
				(INT) CExtPaintManager::__DCBT_ARROW_DOWN
				];
	else if( nButtonType == INT(__EBTT_ELLIPSIS) )
	{
		if( (dwHelperPaintFlags&__EGCPF_NO_BUTTON_ELLIPSIS_DOTS) == 0 )
			pGlyph = 
				CExtPaintManager::g_DockingCaptionGlyphs[
				(INT) CExtPaintManager::__DCBT_ELLIPSIS
				];
	}
	else if( nButtonType == INT(__EBTT_UPDOWN_UP) )
		pGlyph = 
			CExtPaintManager::g_DockingCaptionGlyphs[
				(INT) CExtPaintManager::__DCBT_ARROW_SMALL_UP
				];
...

    if (nButtonType==__EBTT_DROPDOWN) nButtonType = 10;// Shome out of range value...

Dear Support,

I have a multi-line edit box. The scroll-bars are not skinned.
Is this a known problem? Is it going to be fixed in 2.83?

Thanks,
Ron.

Dear Support

I want to stick CMyWnd (class CMyWnd: public CExtNCSB <CWnd>) on CExtControlBar.

CExtControlBar crashes in Focus.

Some kind of container such as CExtTabPageContainerWnd is necessary.

Is not there any good method?

Thanks

That’s true for CEdit, CRichEditCtrl and CListBox etc, but why for have it by default for CExtEdit ? If a user it using CExtEdit I’m sure he want ALL the elements to be skinned.

Other users are welcomed to put their though here as well....

We guess the user should have a choice whether to apply skinned scroll bars or not.

Asking again....:
Why isn’t it applied by default to CExtEdit? don’t we all use CExtEdit in a skinned environment?

These are great news...
One question - Why isn’t it applied by default to CExtEdit? don’t we all use CExtEdit in a skinned environment?

Dear Sir./Madam.,

I’m using the trick at http://www.codeproject.com/KB/cpp/ProfUIS_Dialogs.aspx to have a nice skin for AfxMessageBox. This works pretty well on XP. However, when I run my system on Vista, the buttuons on the message box are not shown. Do you know why? Can you please help me on this?

Thank you very much!

Hello

I am using V2.54 of the library so maybe certain things are only available in later versions.

Our customers ask for the following features:

- Is it possible to add an icon to the right side of the tab in order to close a tabbed window (as in the tabs of Firefox)?

- Is it possible to rearrange the tabbed windows by dragging the tab to another location?

Thanks in advance

Thomas

Dear Support,

There is a small bug in CExtTreeGrid:

1) Have a tree grid with 2 resizeable columns
2) Have another control in the same dialog
3) Have the focus move to that other control
4) Hover over the columns separator and start drag the width of the column.

You will notice that in the first draw, the first cell is computed wrongly - the cell ignores the presence of the Tree box, and draws itself from the beginning of the cell, but in the coming draws it jumps back to the right place.

Note that this happens only if the tree control does not have focums while starting to drag the column width.

Regards,
Ron.

AGAIN:

Dear Support,

Did you get my clip? Were you able to reproduce the problem?

Regards,
Ron.

Dear Support,

You can reproduce this bug using the above steps in the sample application I sent you fro the ItemHide bug I found. Please let me know if you received the mail with the sample application. Please let me know if you were able to reproduce both bugs.

Ron.

Dear Support,

I was able to catch it in a video.
I am sending it to you via mail.

Regards,
Ron.

I am only talking about the separator between the the two columns.
Because this is a flicker, this is not something I can send you in a capture.
I am sure that if you try it several times you will see it.
This is a bug that needs some work for reproducing...

Dear Support,

I would like to remove the dotted lines between nodes.
Can this be done?

Thanks,
Ron.

Asking AGAIN:

So I cannot remove the line that comes like from above the beginning of tree?
What is then the benefit of having the function OnTreeGridQueryDrawOutline ?

So I cannot remove the line that comes like from above the beginning of tree?
What is then the benefit of having the function OnTreeGridQueryDrawOutline ?

The CExtTreeGridWnd::ItemGetRoot() method returns a HTREEITEM handle to the root item which is un-removable. It’s always expanded and it always have a NULL parent item. All the other items can be expanded/collapsed and have non-NULL parent item. So, the outline painting algorithm is exactly the same for any level.

One problem regarding this function:
I would like to know if the line drawing is for the first level items, I don’t see the HTREEITEM of the line being drawn, so I don’t know how it get its parent.

I guess it’s the same question of how to get an HTREEITEM from a row & cell -correct?

Dear Support,

I created a tree which should support sorting, but when the header is clicked I get into this assert:

bool CExtTreeGridDataProvider::SortOrderGet(
	CExtGridDataSortOrder & _gdso,
	bool bColumns // true = sort order for columns, false - for rows
	) const
{
	ASSERT_VALID( this );
	_gdso;
	bColumns;
	// this method must never be invoked
	ASSERT( FALSE );
	return true;
}

Thank you for reporting the tree item hiding problem. It was not difficult to fix but was quite hard to find it. Please update the source code for the following method:

void CExtTreeGridCellNode::TreeNodeHiddenSet(
      CExtTreeGridDataProvider & _DP,
      bool bHide
      )
{
      ASSERT_VALID( this );
      ASSERT_VALID( (&_DP) );
      ASSERT_KINDOF( CExtTreeGridDataProvider, (&_DP) );
bool bHidden = TreeNodeHiddenGet();
      if( ( bHidden && bHide ) || ( (!bHidden) && (!bHide) ) )
            return;
      if( bHide )
      {
            if( TreeNodeIsDisplayed() )
            {
                  ULONG nOffset = TreeNodeCalcOffset( true, false );
                  if( nOffset != ULONG(-1L) )
                  {
                        ASSERT( _DP.m_arrGridVis[ nOffset ] == this );
                        INT nCountToRemove = _ContentWeight_Get( true );
                        _DP.m_arrGridVis.RemoveAt( nOffset, nCountToRemove + 1 );
                        CExtTreeGridCellNode * pNodeParent = TreeNodeGetParent();
                        if( pNodeParent != NULL )
                        {
                              ASSERT_VALID( pNodeParent );
                              pNodeParent->_ContentWeight_Decrement( nCountToRemove + 1, true );
                        }
                  }
            }
            ModifyStyleEx( __EGCS_EX_HIDDEN_TREE_NODE, 0 );
      } // if( bHide )
      else
      {
            ModifyStyleEx( 0, __EGCS_EX_HIDDEN_TREE_NODE );
            if( TreeNodeIsDisplayed() )
            {
                  ULONG nOffset = TreeNodeCalcOffset( true, false );
                  if( nOffset != ULONG(-1L) )
                  {
                        INT nCountToInsert = _ContentWeight_Get( true );
                        _DP.m_arrGridVis.InsertAt( nOffset, NULL, nCountToInsert + 1 );
                        _DP.m_arrGridVis.SetAt( nOffset, this );
                        nOffset ++;
                        _Content_FillVisibleArray( _DP.m_arrGridVis, nOffset );
                        CExtTreeGridCellNode * pNodeParent = TreeNodeGetParent();
                        if( pNodeParent != NULL )
                        {
                              ASSERT_VALID( pNodeParent );
                              pNodeParent->_ContentWeight_Increment( nCountToInsert + 1, true );
                        }
                  }
            }
      } // else from if( bHide )
}

Thanks - problem solved

Now, what about the original question of this thread?...

It would be easier for us to regard the root question in this thread as a feature request and implement tree sorting on a column header click as built-in behavior of the CExtTreeGridWnd class.

Can you please explain what I should do so that the clicking of the column header will call the ItemSortChildren function?
As I explained it crashes now, and you say there is a ItemSortChildren function, but it is not utilized when the header is clicked.

The CExtTreeGridWnd::ItemSortChildren() method sorts child items of the specified tree item (root or any other). This method sorts only the children of one level and does not affect deeper level items. It’s possible to code some recursive method based on CExtTreeGridWnd::ItemSortChildren() method for any custom sorting of all the tree grid or its particular branches. But the CExtTreeGridWnd class does not support any kind of automatic sorting action as a reaction to the mouse click on some header cell at top/bottom because we have no idea which rows to sort or not in according to particular customer needs.
