A property is no longer marked as invalid if wxPropertyGrid loses focus.

Patch: no


I am using a wxPropertyGrid in a modal dialog. This propgrid includes properties based on wxStringProperty, which uses virtual bool wxPGProperty::ValidateValue(...) to validate the user input.
If the user enters an invalid entry and clicks immediately after that on the OK button to close the dialog, without pressing Enter or clicking into another property to confirm the new entry first, the property is not marked as invalid.
The error message is displayed, but without marking the property.

The problem can be also reproduced with the propgrid sample:

  1. Clear the value of wxIntProperty named Y, in category "Position" on the default start page "Standard Items".
  2. Click on button "Show Popup", so that wxPropertyGrid loses the focus. -> An error message will be shown without marking the property.

In wxWidgets-3.1.0 that still worked.

Works corrctly for me (Ubuntu 18.04 and wxWidgets git source)

You are right, on Linux it works.

So it seems to be a Windows specific issue.
I am using wxMSW-3.1.2 on Windows 10.

Fix drawing invalid wxPGProperty

Invalid wxPGProperty needs to be redrawn after setting wxPG_FL_CELL_OVERRIDES_SEL because this flag
is used to select proper colors to mark property as invalid.
This order of operations is important under e.g. wxMSW when redrawing with DrawItemAndChildren() is done immediately.

Closes #18351.
