Minor artefact with CScrollWindowImpl...

Hi Nenad,

I have controls derived from 'CScrollWindowImpl<MyControl, CFSBWindow>' and particularly a DataGrid.
I noticed that when I turned my mouse's wheel (even if I dont need to scroll) some parts of my control were flickering.
So I checked the atlscrl.h file's code, more precisely CScrollImpl and the OnMouseWheel handler (line
#491 for the latest version of WTL) and found this:

if(m_sizeAll.cy > m_sizeClient.cy)
{
    for(int i = 0; i < zTotal; i += WHEEL_DELTA)
    {
	pT->DoScroll(SB_VERT, nScrollCode, (int&)m_ptOffset.y, m_sizeAll.cy, m_sizePage.cy, m_sizeLine.cy);
	pT->UpdateWindow();
    }
}
else		// can't scroll vertically, scroll horizontally
{
    for(int i = 0; i < zTotal; i += WHEEL_DELTA)
    {
	pT->DoScroll(SB_HORZ, nScrollCode, (int&)m_ptOffset.x, m_sizeAll.cx, m_sizePage.cx, m_sizeLine.cx);
	pT->UpdateWindow();
    }
}

This code means that if the mouse's wheel is turned then 
if(m_sizeAll.cy > m_sizeClient.cy) 
    it will scroll vertically and update (repaint) the client rect of the control
else
    it will scroll horizontally  and update (repaint) the client rect of the control

Re: Minor artefact with CScrollWindowImpl...

Hi Philippe,

Thank you for pointing this out. Your solution is what should be there, so
I will add it to the WTL code.

Thanks,
Nenad

Re: WTL AppWizards don't UIUpdateChildWindows(); line to CMainDlg::OnIdle()...

Just checked the latest WTL 8.1 release and this change never got
committed. As there were no objections, can this be committed ?

Best Regards,
Richard B.

WTL exit codes not zero...

I've only just noticed that Wizard based WTL frame apps have a return
code of 1 when the X button is clicked by default, and Wizard based WTL
dialog apps have a return code of 2 when the X is clicked (but returns
button ID if OK or Cancel button is clicked in a dialog app).

Is this to be expected as most GUI based Windows apps return zero to
signify no problems ?

Best Regards,
Richard B.

Thanks Jim.

In future I'll report it in the bug tracker, and may just sign up to the
project as a developer. :)

Best Regards,
Richard B.

RE: Nested Splitters Problem

I think you need a PreTranslateMessage that returns ::IsDialogMessage for
the child dialog.  This is needed for modeless dialogs to drive their
message processing.  You can wire this up either in your dialog class and
attach/detach your message filter appropriately on dialog
creation/destruction, or you could have the frame's PreTranslateMessage
handler call the IsDialogMessage with the child dialog's window handle.  If
you create a new SDI project with the wizard and use a form view (a dialog),
it'll give you the general idea.

Other standard causes of the behavior you mention include not having a
REFLECT_NOTIFICATIONS() entry in the parent's message map and the setting of
WS_CLIPCHILDREN in the parent, though I doubt either of those are your
problem here.

In any event, it sounds like messages are not getting to your dialog window.
