Dear Tk experts,
please allow me to ask for opinions on the ttk::panedwindow widget.
IMHO it may get some love.
My main challenges:
1) in vista theme, the Sash is invisible. There is just a 3 pixel width
line which changes the cursor, if the mouse hoovers over it.
Users may easily overlook it, specially, if the sash is at position 0 or adjacent to another sash.
2) if there is a resize by sash drop, I want to get a callback to save
the sash position for later restoring.
3) if there is a sash drag, I want to control the valid values. For
example, always make a part of the window visible (like a tablelist
title row).
4) I would love to attach additional functionality to the sash, like
right click->menu or double-left-click->zoom.
I suppose, 2-4 may be solved by exposing the widget name of the sash.
For point 1, I hope magic Csaba may look into it.
There are partly solutions on the wiki page, which bind for point 2 and
3 on Button 1 down on the widget. For me, this is more a work-around
than a solution.
Thanks for all !
Harald
Harald,
You mentioned the Wiki. For (1), did you look at the "Create a Custom
Sash Handle bar" section at https://wiki.tcl-lang.org/page/ ttk%3A%3Apanedwindow as well as https://wiki.tcl-lang.org/page/ Custom+sash+handle+for+panedwindow ?

Dear Harald:
I don't know about native themes (win and macos), but I can get a grip
on the default themes on X11 with the following code:
image create photo ::ttk::defaultvgrip -data {
iVBORw0KGgoAAAANSUhEUgAAAAUAAAAbCAYAAAC0s0UOAAAABmJLR0QA/wD/AP+gvaeTAAAA
CXBIWXMAAAsTAAALEwEAmpwYAAAAB3RJTUUH6QEbFwcqynTzIAAAAKNJREFUKM/ljzEKwkAQ

}
image create photo ::ttk::defaulthgrip -data {

ttk::style theme settings default {
ttk::style element create Sash.vgrip image ::ttk::defaultvgrip
ttk::style element create Sash.hgrip image ::ttk::defaulthgrip
ttk::style layout Vertical.Sash {
Sash.vsash -sticky nswe -children {
Sash.vgrip -sticky {}
}
}
ttk::style layout Horizontal.Sash {
Sash.hsash -sticky nswe -children {
Sash.hgrip -sticky {}
}
}
}
ttk::style theme settings classic {
ttk::style layout Vertical.Sash {Sash.vsash -sticky ns}
ttk::style layout Horizontal.Sash {Sash.hsash -sticky we}
}
For better scaling, svg grip images can be used.

the sash position for later restoring.

All this behaviour is scripted, and it can be changed easily. See the
procs in ::ttk::panedwindow namespace, specially Press (bound to <Button-1>), Drag (<Button1-Motion>), Release (ButtonRelease-1) and SetCursor (<Motion>). For points 2) and possibly 3), a virtual event can be used. For point 4), just
use [bind].
While we are here, I want just another possibility: collapsible panedwindows. For an idea of what I'm talking about, see the panedwindow handle of Libreoffice's docked Navigator at https://wiki.documentfoundation.org/images/thumb/3/33/202202EN_Navigator_01_edited.png/300px-202202EN_Navigator_01_edited.png
at the left of Hyperlinks. If dragged, it behaves as a standard panedwindow. But if single clicked, it collapses to the right, hiding the Navigator.
It also changes the direction of the arrow from right to left.
Just food for thought.
