I face the following problems using the Xw widgets: Suppose I create a popup with a TextEdit widget in it. How can I determine the absolute height and width in pixels of the TextEdit widget given I'd like to edit e.g. ten characters? I am using the standard font Fixed but on different terminals the height and width in pixels vary so my lay-out is not consistent. I have tried to solve the problem with the Xlib routine XTextWidth, but that one just returns zero. Can someone send me a fragment of C-source which determines the height and width of a textstring at run-time. Further more I'd like to edit just reals in my TextEdit widget. Can someone suply me with the callback routines which control the input of a TextEdit widget to make sure the input is just a real number.
