I want to position a widget in the middle of the screen. I create a form widget as child of the toplevel widget. How do I get the size of the form widget for calculating the postition of the toplevel widget before realizing the toplevel widget. I made an XtRealize(form); /* get geometry stuff */ XtManageChild(form); XtRealize(toplevel); but I get an Protocol Error on XCreateWindow.

Can't be done, but you can get the information before the widget is mapped. If you set mapped_when_managed to FALSE on a shell widget. I will not be mapped when it is realized. This way you have relize the widget, get its size, relocated it, and then map it. This is a bit ugly, but it looks like it will do what you desire. Chris D. Peterson MIT X Consortium
