a '''paned window''' is a [widget] consisting of two [window]s with a bar down
the middle, where the bar has a handle for resizing the two windows.



** Paned Window Widgets **

   [panedwindow]:   appeared in Tk 8.4

   [ttk::panedwindow]:   a [ttk]-styled paned window

   [BWidget] PanedWindow:    

   [ClassyTk] Paned widget:   

   [Iwidgets] PanedWindow]:   

   [obTcl] PanedWindow:    

   [Tix] paned window]:   

   [MegaWidget package] ,by [Jeff Hobbs]:   includes a pure-Tcl geometry-manager-like-thing that serves as a paned window.

** Description **


Do any of these extra paned windows provide features that don't exist in the native Tk [panedwindow]?

[EKB] Not exactly, but... I decided not to migrate away from the iwidgets paned
window (yet) because the Tk 8.4 version doesn't have the iwidgets "fraction"
option. Instead, you have to specify the size of each pane. Setting "fraction"
instead is quite handy. Of course, this isn't a show stopper, but it made the
switch nontrivial.

[EKB]: Oh, right... And ''more'' importantly, there is no '''hide''' command
for the Tk 8.4 paned window. Again, it's not a show stopper, since the behavior
can be duplicated, but it slows me down when converting scripts.

[LV]: Might be worthwhile to add these two ''missing'' features to the Tk
Features Request queue over on sf.net .

----

[[Does [Perl/Tk] have a Pane widget?]]  [VK]: [Perl/Tk] has Tk::Adjuster,
which, according to docs, ''Allow size of packed widgets to be adjusted by
user''. Strangely, it has [Tix] mixed in, but PanedWin from Tix was not used,
for some reason it has its own... Some kind of implementation details.
