Re: Application development using GTK and GLADE3

["Dov Grobgeld" <dov grobgeld gmail com>]

The way I solve this is by actually subclassing GtkWindow for each window and then add pointers to the rest of the widgets in that window. To achieve the window interdependencies I either pass around pointers to other window or even cleaner, create signals that I send from one window and listen to in another windows. This is imho the proper "GObject" way of doing things, but I agree that the syntax is quite messy both for subclassing and for adding signals. This is why I use gob2 which makes it trivial both to subclass and to add new signals to a class.

Hi.

I think it's common practice in gtk programming to create structure of
all widgets that are needed across the application and then pass a
pointer to that structure to the callbacks that need access to GUI.
