Bind in Snit megawidgets

[Silas]

Hi there!

I'm trying to bind a event of a Snit megawidget. I call it Xtext and
it is a wrapper around [text] widget. I'd like to bind all Xtext of
the application. I'm trying:

bind Xtext <Button-3> {puts something}

But this doesn't work. The following, thought, works:

bind Text <Button-3> {puts something}

But it is unwanted, since it bypass all nice wrapper I made around
[text] that I wanted to use. It seems that new classes that snit
creates don't work well for binds.

Any tips?

Thank you.

The text widget you're wrapping is still a [text] widget; so its
bindtags include Text, not Xtext. Replace Text with Xtext in the
bindtags, and you should be good to go.

Yes, it works as people told me on the chat. There is a little
problem, though. When binding the widget, the %W substitution
substitutes to the [text], not my megawidget (so I cannot use my
megawidget methods). Should I use [winfo parent %W]? It looks ugly,
but if it is the only way...

Thanks.

If your megawidget is only and entirely a wrapped text widget, you can
use a snit::widgetadaptor, and %W will be the text widget. If you're
wrapping other widgets in as well (i.e., scrollbars) then that won't
work, and [winfo parent %W] is what you'll need to do.

Don't put the tags on the 'inner' component widget, put it on the
container widget (usually a frame, but you can change that). If the
*only* component of your megawidget is the text widget, then you can
create a snit::widetadapter instead of a snit::widget and make the hull
the text widget itself.
