The main window of my current project comprises a Grid control and a
TreeView, in a Windows Explorer-like layout. I would like to provide the
option of being able to resize the two controls by click-and-dragging the
area between the two. Does anyone have any tips on how to do this? I tried
adding a "-resizable => 1" option to the TreeView, but that would have
been too easy! (It didn't work, of course). I imagine it makes use of the
MouseOver et al. events, but the documentation is a bit thin on those
events. Do I have to put another control (a 1-pixel-wide button perhaps?)
between the two to get at the events? As usual, an example would be worth
a thousand wordsÂ…
Use the Splitter control.
Perl Oasis uses this for an example:
http://user.bahnhof.se/~johanl/perl/Oasis/download.html
For a smaller and more focused example, download The GUI Loft
http://user.bahnhof.se/~johanl/perl/Loft/
and look at the Demo/FileDisplay(manual_resize) example. The purpose of
that demo is exactly what you're after.
(using the Splitter makes TGL unable to handle all resize code
automatically for you, but it still gives a helping hand by providing the
basic resize code for the simple things (but not Splitter) which you can
adjust and paste into your source).
