GTK+ Forums

Could someone direct me toward an example of how to change a window's menubar (the menu labels, and the items/submenus within) by selecting a GtkNotebook tab? I mean, like a GtkNotebook menubar on the window, being changed by selecting a tab on a GtkNotebook beneath it.

Sorry can't be done.
Gtk builds on top of whatever window manager a system uses and so can only portably provide menu features that are consistently available across the range of window managers. So no notebook tabs in menu bars.
You do; as always, have alternatives available. E.g. you can put a notebook in the main space of your program and then connect up a signal that when the tab changes it will scrub the menubar and repopulate it according to whichever tab is selected.
There is also alternatives to the notebook if you just want a selecter. E.g you could have a gtkradiomenuitem group in your menu which when changed would then change the rest of the menubar.

You misunderstood, which was probably my fault. I'm bad at explaining things, sometimes, but here goes another try:
My goal isn't to put notebook tabs in the menu bar, but to make the menu bar at the top of the window show different things, depending upon which tab is currently selected.


That's exactly what I was asking how to do. I'm not sure about tab callbacks, though, so I was hoping this process (perhaps with a concise example) could be explained to me, since I've never worked with tab callbacks or menu changes before.

I thought I was misunderstanding so gave options. it was the ``GtkNotebook menubar on the window'' that did it. Sorry didn't want to elaborate on too long if I wasn't on the ball. The following is for gtk+2 in c.
You need to connect a signal to the tab (here vbox is the box that you would pack the menubar into - if you want to encapsulate further rather than use global variables then you'd have to build a structure to pass):

you then create the callback function according to the switch-age prototype:

I'll give this a proper effort tomorrow, or the day after. Thanks! I'd tack a 'solved' onto the this, but I'd have to shorten the title, first. ^_^

I noticed that thing about the GtkNotebook menubar on the window, and I'll be more careful in my wording from here on. Thanks, again!

I'm glad I checked this, actually; I was having the nuttiest results from notebook callbacks. @_@; This example just spared me an aneurysm, I think. :) Thanks a million, to both of you!
