wxOwnerDrawnComboBox assertion

[Trigve]

When using wxOwnerDrawnComboBox and clicking to drop-down arrow, popup window is shown. Then clicking again on popup arrow (while popup window is shown) I get an assertion:

19:17:26: Debug: ..\..\src\common\combocmn.cpp(1842): assert
"!IsPopupWindowState(Visible)" failed in wxComboCtrlBase::ShowPopup(): popup
window already shown

stack:

Sorry, I still can't reproduce this, even with your sample. Can anyone else try this?

Also, what sort of Windows system are you running on? FWIW, I have Windows XP SP3.

Replying to jmsalli:

I'm using Windows Vista.

I had the same problem with wxComboCtrl default implementation of popup-arrow click, but there I've overridden "OnButtonClick" method:

void ComboBoxOwner::OnButtonClick()
{
    // Close popup if shown
    if(IsPopupWindowState(Visible))
	GetPopupControl()->Dismiss();
    // Show popup window
    else
	ShowPopup();
}

There's nothing wrong here [any more].
Tried on Win7 in the widgets sample, combo sample and a modified minimal sample with the code in the OP's file. No assert for wxOwnerDrawnComboBox or wxComboCtrl.

Thanks for testing!
