CXTTipWindow bug

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi!

XTP 9.70

I realized, that when a CXTTipWindow based tooltip window is to close to the screen border, the tooltip isnt always displayed if m_rectTipArea is used.

m_rcScreenWindow gets modified in the case that the tooltip window is exceeding the screen area within InitializeSize() but m_rectTipArea remains the same.

therefore the code within OnMouseMove() doesnt work correctly because point is relative to the modified position of the tipwindow and is used with the unmodified m_rectTipArea. Thats why the tooltip window gets hidden ALTOUGH the mouse cursor is within the tiparea:

CXTTipWindow::OnMouseMove(UINT nFlags, CPoint point)
{
    if (!m_rectTipArea.IsRectNull() && !m_rectTipArea.PtInRect(point))
        HideTipWindow();
}

I need a possibility to solve this and would appreciate any commentd on how to fix this problem!

regards,
Hans
