Hello,
It seems that resizing in GLDrawDemo dosen't work properly.
The first worse solution is just to add explicit glVieport invocation in GLPaint() method(GLDrawDemo - main.cpp - Line 10):
virtual void GLPaint() {
Size sz = GetSize();
glViewport(0, 0, (GLsizei)sz.cx, (GLsizei)sz.cy); // <- We need to add this line
...
}
The second much complex solution is to extends a little bit GLCtrl. I think that Layout method should call glVieport function by default. Below is a proposal of my code (beta version):
void GLCtrl::Layout() {
if(controlVieport) { // <- Additional flag, enable by default
Size sz = GetSize();
glViewport(0, 0, (GLsizei)sz.cx, (GLsizei)sz.cy);
}
Ctrl::Layout();
}
Please review above proposition.
Sincerely,
Klugier
