GDI+ not clearing my window on repaint for vista
- by Michael
on WM_PAINT i do the following:
//RectF mNameRect;
//WCHAR* mName;
//HWND mWin; // this is the window handle
{
PAINTSTRUCT ps;
HDC hdc = BeginPaint(mWin, &ps);
Graphics g(hdc);
g.Clear(Color::White);
StringFormat stringForm;
stringForm.SetLineAlignment(StringAlignmentCenter);
stringForm.SetAlignment(StringAlignmentCenter);
// set the rectangle to the size of the whole window
mNameRect.Width = static_cast<float>(size.cx);
mNameRect.Height = static_cast<float>(size.cy);
g.DrawString(mName, -1, &mNameFont, mNameRect, &stringForm, &mNameBrush);
EndPaint(mWin, &ps);
}
In XP this works fine, the mName is displayed in the middle of the window. However on Vista the text doesn't move, it stays in its location no matter how I resize the window. the g.Clear(Color::White) doesn't seem to do any difference. The text doesn't even change position when the window is hidden behind another window and on focus needs to be repainted again.
How do I make mName change position in Vista?
