is this something that I must do for -every- combination of required
data for all my callbacks? Or should I just create one enourmous
structure and set only the needed elements in that?
Seems inefficient.
Also, some of this data isn't stuff that I know how to access
-anywhere-. I used glade to create the interface, so, for example, if I
want to use a button to save what was typed into a text field, how do I
retrieve the text to be saved? I can't access the textbox widget
itself, because that was created by glade in the "interface.c" file and
I have no way to store a pointer to that widget. If I edit interface.c,
glade will just overwrite my changes when I edit the interface.
Is there a way to retrieve pointers to a specific widget from within the
callback?
Thanks,
-Ron

Ron,
I would create a structure (typedef) with all required data and pass a
pointer to a variable of that type.
Then, in your callback function, just retreive the data by casting
gpointer* to the proper typedef.
Cheers,
Olivier.

Hello,
I have an application which spawns another toplevel window. I would
like the user to be able to close this window by clicking on
File->Close. I currently have the callback for that menuitem call
another function which does some cleanup (Saving date, etc), and then I
wish to close the window. However, I don't know what to pass to
gtk_widget_destroy(). The only data that's available in my callback is
the GtkMenuItem that was clicked. How do I get the widget that I need
to delete the toplevel window?
I often have problems like these. I have a button whose callback needs
data about some other widget elsewhere in my program. In general, how
do I pass this data to my callback or retrieve the data from within the
callback?
Thanks! I hope my question was clear. Please forgive me if the answer
is obvious.
Ron
