2Q: how to change window contents and GnomeUIINFO

Hello, everyone. I have 2 problems:

1) How I can change window contents on the fly? I want to remove unwanted widgets and add new widgets.

2) In my program I create menu using GNOMEUIInfo. For example:

Code:

...
static GnomeUIInfo filemenu[] = { 
   GNOMEUIINFO_MENU_OPEN_ITEM (callback_function, my_data)
};
...
static GnomeUIInfo menubar [] ={
   GNOMEUIINFO_MENU_FILE_TREE (filemenu),
   GNOMEUIINFO_END
};

int main(argc, char *argv[])
{
...
gnome_app_create_menus(GNOME_APP(app), menubar);
...

I understand how I can set callback function for menu item, but how i can set data to this callback function? (For example, I want to open file which contains some data, which I want to display in main window).

Thank you!

This is simple: destroy unwanted widgets using gtk_widget_destroy() (if you destroy parent widget, all children will be destroyed too) and then simply create new controls.

Don't use this, since gnomeui library is deprecated for quite a while now. Use GtkUIManager for this task. You can find migration assistance here.

Ok, thank you for fast answer.

I add actions to group like it:

Code:

gtk_action_group_add_actions (group, entries. number_entries, (gpointer) data_to_cb);

I try to transfer pointer on vbox from main function to callback function, but when i try to add widget to vbox with

Code:

gtk_box_pack_start(GTK_BOX(vbox), widget_to_pack, TRUE, TRUE, 0);

it did't added, that is, no change occurs. I tried to send from the main function pointer to a label and change it, then to the callback function and it's going well. Is there any way in callback function to add widgets into the vbox?
