Image mouse control!

OpenGL OpenGL: Basic Coding

Hi! I am trying to display two images simultaneously and was wondering if it possible to have a separate mouse pointers for each image and if yes then which function do I need to use. I would appreciate any help!!!

Thanks

Hi I have tried to do this but then the cursor is always for the first file.

    glutInitDisplayMode( GLUT_RGB |GLUT_DOUBLE| GLUT_STEREO);
    BitmapBits1 = LoadDIBitmap("earth.bmp", &BitmapInfo1);
    BitmapBits2 = LoadDIBitmap("pic.bmp", &BitmapInfo2);
    glutInitWindowSize((int)BitmapInfo1->bmiHeader.biWidth,
                 	     (int)BitmapInfo1->bmiHeader.biHeight);

    glutInitWindowPosition(250,250);
            glutCreateWindow("Stereo Image Viewer");
    glutReshapeFunc(Resize);
    glutDisplayFunc(Redraw);

    if(BitmapBits1)
    {

            // changes the cursor image of the cuurent window
             glutSetCursor  (GLUT_CURSOR_CYCLE);
             glutMouseFunc(Handler);
    }
    else
    {
              // mouse pointer for the second file
              glutSetCursor  (GLUT_CURSOR_HELP);
              glutMouseFunc(Handler1);

    }

and if I take the if statement out then it displays for the second file only…

does anyone know how to do it.

Thanks

Should not the cursor change code not be in the display routine???

How many windows are you using and how are you drawing into them? Once you’ve let glut take over, I don’t think you can change the mouse function. But you could have a smart mouse function, so that shouldn’t matter.

PS
Lay of the exclamation points.

well what is a smart mouse function…??? and how can i make one ??

p.s- I am using one window do display both images by using quad buffering. And want to have different mouse pointers so that I know which image I am in.

Thanks

Even if I put the mouse function in the display functgion it just displays for the second image.

You can e-mail me your code and I can see what I can do, just remember to include the image files to be loaded.
