I have a question that is in regards to a previous post I had, in summary
this is it:
I have (created with the MW constructor) it has a button and a scrollbar on
it.
The coordinates for the form are: 2,2 and 156,156.
The idea is to have a 2 pixel border around the form.
If I do nothing and just show the form, the form looks and acts as expected.
(e.g. if I click the button, it turns black, if I update the scrollbar it
updates) - Note: nothing moves.
BUT, if I add a function that does this:
WinHandle hwinBuffer = WinCreateOffscreenWindow (156, 146, nativeFormat,
&error);
if ( hwinBuffer != NULL )
{
WinSetDrawWindow(hwinBuffer);
WinEraseWindow();
// perform some WinDrawChars functions
WinSetDrawWindow( WinGetDisplayWindow() );
RectangleType rect;
rect.topLeft.x = 0;
rect.topLeft.y = 20;
rect.extent.x = 156;
rect.extent.y = 126;
xDisp = 2;
yDisp = 18;
MyWinCopyRectangle( hwinBuffer, NULL, &rect, xDisp, yDisp, winPaint );
}
if (hwinBuffer)
WinDeleteWindow(hwinBuffer, false);
Then draw the form, both my button and my scrollbar are now off by 2 pixels.
(e.g. if I click the button, a black button appears -2,-2 pixels from the
actual button, same goes for the scrollbar)
Of course this does not happen while using a 0,0 and 160x160 form.
Therefore I make the assumption that for some reason when the system calls
the CtlHandleEvent function, the coordinates of my controls are screen based
and not Form based, therefore when it refreshes the controls, it puts them
where it thinks they should be..
My question is: Is this an OS issue or a MWCW issue? - Is there a
workaround?
thanks - bill
