glutInitWindowPosition(3GLUT) GLUT glutInitWindowPosition(3GLUT)
NAME
glutInitWindowPositionWindowPosition, glutInitWindowSize - set the ini-
tial window position and size respectively.
SYNTAX
void glutInitWindowSize(int width, int height);
void glutInitWindowPosition(int x, int y);
ARGUMENTS
width Width in pixels.
height Height in pixels.
x Window X location in pixels.
y Window Y location in pixels.
DESCRIPTION
Windows created by glutCreateWindow will be requested to be created
with the current initial window position and size.
The initial value of the initial window position GLUT state is -1 and
-1. If either the X or Y component to the initial window position is
negative, the actual window position is left to the window system to
determine. The initial value of the initial window size GLUT state is
300 by 300. The initial window size components must be greater than
zero.
The intent of the initial window position and size values is to provide
a suggestion to the window system for a window's initial size and posi-
tion. The window system is not obligated to use this information.
Therefore, GLUT programs should not assume the window was created at
the specified size or position. A GLUT program should use the window's
reshape callback to determine the true size of the window.
EXAMPLE
If you would like your GLUT program to default to starting at a given
screen location and at a given size, but you would also like to let the
user override these defaults via a command line argument (such as
-geometry for X11), call glutInitWindowSize and glutInitWindowPosition
before your call to glutInit. For example:
int main(int argc, char **argv)
{
glutInitWindowSize(500, 300);
glutInitWindowPosition(100, 100);
glutInit(&argc, argv);
...
}
However, if you'd like to force your program to start up at a given
size, call glutInitWindowSize and glutInitWindowPosition after your
call to glutInit. For example:
int main(int argc, char **argv)
{
glutInit(&argc, argv);
glutInitWindowSize(500, 300);
glutInitWindowPosition(100, 100);
...
}
