Hi Phil, Alan I tried evtCreateExample.cpp and I get the good expected result. This just means that for this simple example the OnCreate event is triggered.
To note that on my bad results of the PLplot demo, the OnCreate event is *also* triggered. the problem is that is triggered after the plot was made 11:09:13: Debug: wxPLplotwindow::wxPLplotwindow 11:09:13: Debug: frame->Create 11:09:13: Debug: pls NULL 11:09:13: Debug: wxPLplotwindow::OnCreate I am not that familiar with the wxWidgets internals but it seems events are put in a queue. http://docs.wxwidgets.org/3.1/overview_events.html it could be that the event is not processed in the expected order or delayed for some reason. this could be a good question for the wxWidgets support list. -Pedro On 2016-12-15 21:11, Alan W.
