Gtkmm / UIManager / passing info to event handler

cheeseplz · 10-18-2007, 11:04 PM

Greetings all,

I've a newbie question relating to Gtkmm and the UIManager.

How can I pass arbitrary data to the event handler when a menuitem created with the UIManager is clicked?

At the moment I have three event handlers handling three different items, but the code only differs by an integer value, which I would simply like to pass to a single event handler. How can I do this?

Hope that made sense.

Much appreciate some assistance with this :-)

Thanks,
Lee

My recommendation is to write the function that does the real work and takes an integer. Then write the 3 callbacks that gtkmm will see - but all these will do is call the function that does the real work and pass in the appropriate integer.

Hi Patrick,

Thanks for your response :-)

That's what I have done. It just seems repetitive to do it that way, even if on a small scale, and I assumed there must be a simple way to pass data to the event handlers.

Thanks again :-)

Well, there may be a way, but it involves a greater knowlege of libsigc++ than I have. Take a look at this link (btw libsigc++ is the callback framework that gtkmm uses) http://libsigc.sourceforge.net/libsi...html#id2450855 . I think rebinding is what you are looking for.

Hi Patrick,

Perfect! Thank you very much! :-)

bind was precisely what I was looking for.

Thanks again!
