Xtreme Toolkit Pro v11.2.1 on Vista

CXTColorPopup in MDI applications crashes on closing "More Colors..." dialog which was opened from the popup.

To reproduce the crash take CCustomItemColor from "PropertyGrid\GridSample" sample and add it to Property Grid in "PropertyGrid\DrawClient" sample. Open the color popup, choose "More Colors...", the dialog opens but the popup closes (which is different from behavior in "PropertyGrid\GridSample") and once you close the dialog you'll get the crash.

Also, CXTColorPopup sends two CPN_XT_SELENDCANCEL if it closed by clicking on a different window, once from CXTColorPopup::OnKillFocus and once from CXTColorPopup::OnActivateApp, and it can be reproduced in "PropertyGrid\GridSample" sample by adding corresponding handle in CCustomItemColorPopup.

Thanks.

Hi,

Thanks, can you please patch sources - in CXTColorPopup::OnKillFocus replace

if (!IsColorDlgVisible())
{
EndSelection(-1);
}

if (!m_pColorDlg)
{
EndSelection(-1);
}

Thanks, the patch fixed the crash.

Besides CPN_XT_SELENDCANCEL being sent twice on canceling the popup, CPN_XT_SELENDCANCEL event is also sent after CPN_XT_SELENDOK event on selection of a color.
