That seems okay so far. Calling init_sizes() is the right way to go. > This works fine, but if I resize the main window after hiding the sidebar, > then show the sidebar, it's width is changed.

Something you calculate? > Am I doing something wrong or is this a bug? > I have an example program (a revision of the test/resizable program) Posting a short example program would be helpful. Resizing widgets is a complicated thing. As I wrote in another thread, init_sizes() clears the internal array of widget positions and sizes withing a group. When the group (or window) will be resized later, the new positions are calculated from the saved information. If you called init_sizes() previously, then a new array will be calculated from the widget positions that are active when you resize the group. Maybe this helps - otherwise please post your example program.
