You're welcome, glad I could help.
I was going to send an email questioning the reasoning of both
solutions assuming both were
working (Phil's and mine), but I just tried on my CentOS with the
latest git code, and what happens
is that the execution is always on
12:50:24: Debug: Plot() Yielding
About the solutions
1) Current solution
Right now, this has to be done in the client code
//We must wait for the Create event to be processed and the
//wxPLplotstream to be prepared
while (!frame->IsReady())
{
PLPLOT_wxLogDebug("Plot() Yielding");
wxGetApp().Yield();
}
So, the user has to do some extra step in order to wait for wxWidgets
to
process some event.
Ideally he should not have to do this but rather all should be done
inside wxWidgets.
This is error prone, because the usual way to use wxWidgets is
MyFrame *frame = new Frame()
frame->Show()
here we have
MyFrame *frame = new Frame()
frame->Create()
While ()
{
wait()
}
frame->Show()
Plot(
so a user might not even be aware of this wait extra step.
that is assuming it's working, but on my CentOS it gets stuck on the
Yield()
2) Solution of creating the fame in Show()
Client code is
MyFrame *frame = new Frame()
frame->Create()
frame->Show()
Plot()
there is no wait loop; there is also no need to create the stream in
OnCreate()
