bind e.g. <Alt-5> ?

[japskar]

Hi,
currently I'm working on a piece of code for binding keysequences to action.
So far, so good. But I can't get my
&quot;bind all <Alt-nr> {......}&quot; working for nr=1 to 5

&quot;bind all <Alt-6> {.....}&quot; however, works fine

what's the problem here?

I tried it and it works fine. Of course, the syntax is:
bind all <Alt-$nr> {...}
not
bind all <Alt-nr> {...} Bob Rashkin

Yes sorry, I wasn't precise in my formulation of the problem.
But....strange.
Can you try this for me?:

pack [button .b1 -text {Button1} -command {puts {invoked button1}}]
pack [button .b2 -text {Button2} -command {puts {invoked button2}}]
bind all <Alt-5> {.b1 invoke}
bind all <Alt-6> {.b2 invoke}

it only triggers .b2

I'll bet you'd notice even stranger behavior if you tried binding to [tt]<Alt-1>[/tt], [tt]<Alt-2>[/tt], or [tt]<Alt-3>[/tt]. At the very least, I think you'd be surprised to see the bindings fire when the user held down the Alt key while clicking one of the mouse buttons...

What you're experiencing is one of those traps that people encounter when they use abbreviated binding descriptions. For many KeyPress events, you can get by with providing only the keysym. So, [tt]<a>[/tt] is equivalent to [tt]<KeyPress-a>[/tt], and [tt]<Control-a>[/tt] is equivalent to [tt]<Control-KeyPress-a>[/tt].

On the other hand, Tcl also allows you to abbreviate ButtonPress events, so [tt]<1>[/tt] is equivalent to [tt]<ButtonPress-1>[/tt]. And [tt]<Alt-1>[/tt] through [tt]<Alt-5>[/tt] is equivalent to [tt]<Alt-ButtonPress-1>[/tt] through [tt]<Alt-ButtonPress-5>[/tt].

Solution? Bind to [tt]<Alt-KeyPress-5>[/tt]. And be very careful relying on abbreviated event descriptions in bindings. - Ken Jones, President
