Re: wxButton->Disable(); throws read access violation exception
This is incredibly embarrassing, but I see that the buttonSettings value accessed by the call to disable was one that I had duplicately declared in another part of my program, thus causing the crash.

wxPanel re-sizing issues
Hi everyone, I am currently working on a UI with wxWidgets. I'm constructing a space in the application to display a live stream video, with a big wxPanel "panelContent" that itself contains two smaller wxPanels: one to display the actual stream, "panelStream", and the other, sma...
