menu flash vs. key bindings

[Hans-Christoph Steiner-2]

Hey all,

I would like to have my Tcl/Tk app be able to have no windows on Mac  
OS X. I am using [wm withdraw .], and then every window subpath of  
".".  I then have a single 'menu .menubar' which I attach using  
[.pdwindow configure -menu .menubar].  I am then binding the keys to  
each new toplevel's path as its created (each document gets its own  
toplevel).

The first thing I noticed in trying to eliminate the last window is  
that after doing [. configure -menu .menubar], I have a menubar that  
has the nice little flashes when you hit an accelerator.  I've never  
been able to get that working otherwise.  But the downside is that the  
keys don't actually trigger anything.

Is there a way to keep those flashes and have working key bindings?

The code is all here, with the most relevant files being  
"pd_menus.pd", "pdwindow.tcl", "pdtk_canvas.tcl", and  
"pd_bindings.tcl".  pd-gui.tcl is the "main".

note that menu accelerators specified in Tk are just decoration, they
don't cause any key bindings to be executed and thus have no impact on
functionality.

In TkAqua Carbon it is not possible to get the correct user-interface
feedback when key-bindings are triggered that happen to coincide with
a menu accelerator (key event processing happens before the native
menu code gets a chance to see the event).

In TkAqua Cocoa, this is fixed, all menu accelerator keys cause the
expected user-interface feedback (even when there is no corresponding
key binding however, so the menu may highlight event though nothing is
executed, IMO that is the lesser of two evils however...)

Cheers,

Daniel
