So I'm working on this OpenGL 3D Graph program, and like, I ran into some trouble, since I wanted it to support fullscreen, so I made the following;
int main(int argc, char *argv[])
{
... // Some stuff
glutSpecialFunc(SpecKey);
... // More stuff
}
Which is calling the following function;
GLvoid ResetWindowSize(GLvoid) // Reset WindowSize
{
glutReshapeWindow(WindowWidth, WindowHeight);
glutPositionWindow(0,0);
}
GLvoid SpecKey(GLint key, GLint x, GLint y)
{
if (key == GLUT_KEY_F1) // Toggle FullScreen
{
fullscreen = !fullscreen; // Toggle FullScreenBool
if (fullscreen)
{
glutFullScreen(); // Enable Fullscreen
}
else
{
ResetWindowSize(); // Make Window, and resize
}
}
}
WindowWidth and WindowHeight are both global variables, which are updated everytime I'm resizing the window.
fullscreen is a global bool.
The problem is, that going to fullscreen is working fine, however returning to windowed mode, is giving me some problem since it returns with a window resolution equal to my desktop resolution, and not the resolution which is givin' in the variables WindowWidth and WindowHeight.
Anyone able to figure out the problem?
EDIT; I'm able to get it into a fixed resolution using fixes values instead of the variables like this;
GLvoid ResetWindowSize(GLvoid) // Reset WindowSize
{
glutReshapeWindow(800, 600);
glutPositionWindow(0,0);
}
However to make this work I'm forced to call the "ResetWindowSize" function twice?
