Hello all. I'm having some trouble with positioning widgets and having them automatically shifted when the enclosing widget is resized. What I am seeking is the nice management that a selection box uses for its pushbuttons. When the selection box is resized, the buttons are shifted and stacked to proportionally fit the available space. I have three PushButtons which would like similarly handled at the bottom of a FormDialog. At the moment, I am using a form to contain them, but I haven't been able to place the middle button specifically at the center of the form; the closest I can come is to make its left attachment to a position that I initially calculate to be at the correct location for the original window size; resizing the FormDialog larger works fairly well, but larger sizes show the button as no longer centered. Additionally, when the form shrinks below optimal size, the buttons start to overlap and are not restacked. I have tried a RowColumn container widget; it didn't even space out the buttons when the window was enlarged. I also tried a BulletinBoard dialog, but that also failed. Am I missing some kind of container that would help? Am I using the right container, but specifying the attachments incorrectly? I tried looking at the SelectionBox source for hints, but it does lots of internal stuff with the Geo__.c functions which are not available to standard clients (or are at least undocumented to my knowledge). Any help would be appreciated, and more specific info is available on request. I would settle for proportional placement on window expansion, although the stacking is nice when the window is small. Also, any word on when the Xm library might be available in a shared library format?

Then leftAttach the leftmost button to the form, and rightAttach the rightmost button to the form. Then, the key thing is to make the rightAttachments of the first four buttons to be attachPosition, using some appropriate percentage of the distance, and make leftAttachment of the 2nd through 5th buttons attachWidget to the button to their left. Then your buttons will all resize correctly. Terry Traub Fidelity Investments Boston, Mass. ttraub@fmrco.UUCP (uunet!fmrco!lanyard!ttraub)
