[Ttk]'s [menubutton] [widget].

----

[jnc] To invoke a menu button (or almost any other widget that takes a `-text` and `-underline` option) by a keystroke you can:

  event generate $widget <<Invoke>>

Such as:

  bind <Alt-f> . {event generate .menuButton <<Invoke>>}

<<discussion>>Alignment question

[HaO] 2010-11-16 Is there any possibility to center-align the menu button text and image ?
This would make the following example nicer (on Windows Vista classic theme):

[http://wiki.tcl.tk/_repo/images/align_toolbuttons.png]

("Laden" has nothing to do with the person, it is German for "Load (Module in this case)")

Labels and Images are left-aligned.

Code fragment (not that of the screenshot):

======
% pack [ttk::menubutton .t1 -text abcabcabc] -fill x
% pack [ttk::menubutton .t2 -text a] -fill x
======

Style investigation:
======
% ttk::style layout TMenubutton
Menubutton.border -sticky nswe -children {Menubutton.focus -sticky
nswe -children {Menubutton.indicator -side right -sticky {}
Menubutton.padding -expand 1 -sticky we -children {Menubutton.label -
side left -sticky {}}}}
======

I think, the issue is the last part. "-side left -sticky {}" which
should be changed to "-sticky news"
Is this possible in an easy manner ?

---
Even harder, I want to have it with Toolbutton style:

======
% pack [ttk::menubutton .t1 -text abcabcabc -style Toolbutton] -fill x
% pack [ttk::menubutton .t2 -text a -style Toolbutton] -fill x
======

How to align the labels "centered ?"

---
Style investigation:
======
% ttk::style layout Toolbutton
Toolbutton.border -sticky nswe -children {Toolbutton.padding -sticky
nswe -children {Toolbutton.label -sticky nswe}}
======

Here, the label has -sticky "nswe". So try some label-options:
======
% ttk::style configure Toolbutton.label -justify center -anchor center
% pack [ttk::menubutton .t3 -text a -style Toolbutton] -fill x
======

But stil left-aligned...

Why is a normal Button centered and a MenuButton left-aligned ? 

If you have an answer feel free to remove all this and replace it by more helpful stuff.
I have posted this on c.l.t. with no answer and solved it by putting the label to the right of the icon so it looks pretty when left-aligned.
