Hi
in 14 Jul 2009
http://www.mail-archive.com/perl-win32-gui-users@lists.sourceforge.net/msg05703.html
i have posted an opengl example to run from within win32gui , the example
depends on kevin Marshall code posted here
http://www.mail-archive.com/perl-win32-gui-users@lists.sourceforge.net/msg05673.html
.
the example show a popup child window in wich the opengl scene rendered.
now i have tried the same example but the opengl scene will be rendered to a
child window inside the main window; it is working but with one problem; the
launching of the program lasts about 5 seconds before the main window appears.
why is this behaviour?, since in the popup child window example the main window
appears in one second only.
the only adjustments i have made is :
1- adding the following lines to the render sub since the sticky child window
can't be resized so the -onResize => sub {...} is not operative:
glViewport(0,0,320,240);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluPerspective(45.0, 320 / 240, 0.1, 500.0);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
2-adding to the child properties:
-popstyle => WS_CAPTION | WS_SIZEBOX,
-pushstyle => WS_CHILD,
-pushexstyle => WS_EX_CLIENTEDGE,
and the else of the program is the same as the first example.
for convenience here is the modified program, so you can check the 5 seconds
delay before the main window appears:
