I am very new to Tk - and to anything graphical in general - so I may well be missing fundamentals. I'm trying to create a view showing a fragment of a larger world (A), with a pane below for control options (C), and a pane to the right showing details of an element in the world (B):
+-------+---+ | | | | A | B | | | | +-------+---+ | C | +-----------+ I'm using a horizontal Panedwindow for A, B, and a vertical Panedwindow for A+B, C, so the user can control the width of B and the height of C. When the window is resized, I want the width of B and height of C to stay constant, and the primary window A to shrink or grow as needed, hopefully with some event I can bind to update its contents. However the opposite is happening: A stays constant, and the other two resize. I suspect this is the nature of a Panedwindow: if I swap the order I add A and B to the upper pane, for example, the size of B stays fixed on resizing (but it's now on the left). However I don't see anything in the docs for Panedwindow to control this, nor do I see in the code how it handles resizing events. Can someone suggest how to achieve the effect I want? Update: as pointed out by choroba, this is the nature of a Panedwindow. So can someone point to how that is implemented, so I can create a variant of a different nature? Another update: in Tk-8.5, panes in a Panedwindow acquired a new stretch attribute that controls how new space is allocated among them. 8.5 also includes ttk, which has its own variant of Panedwindow; this one lets you specify a weight attribute on panes for even finer-grained control. Current Perl-Tk is based on Tk-8.4, so I guess I need to go bug Slaven. I did this in issue 75, which got a comment from chrstphrchvz. More: tybalt89++ offered a solution in Re: Controlling resize of Tk::Panedwindow which looks to do exactly what I want; I'll be going with that for now. An Anonymous monk looking a lot like zentara also pointed me at a couple of alternative Panedwindow implementations in Re: Controlling resize of Tk::Panedwindow (IDELayout IDEpanedwindow), but the one of those I looked at seems quite buggy. kcott also offered a decent cut-down solution in Re: Controlling resize of Tk::Panedwindow if I didn't mind losing the user-controllable aspect of paned windows.
