Re: Accelerators for GtkNotebook to switch between pages
Oh no sorry. It not working. I had just defined the t
accelerator in the activate function of the app.
If I change it to e.g. b the accelerator doesn't work.

Re: Accelerators for GtkNotebook to switch between pages
Hi infirit,
crazy. I rebuilt the relevant parts in a demo app and there it's working
as expected. *argh*.
For completeness here's what I mean.
The code that creates my GtkNotebook:
/* notebook */
notebook = gtk_notebook_new();
gtk_notebook_set_tab_pos(GTK_NOTEBOOK(notebook), GTK_POS_TOP);
gtk_notebook_set_scrollable(GTK_NOTEBOOK(notebook), TRUE);
gtk_container_add(GTK_CONTAINER(frame), notebook);
/* notebook page 1 */
label = gtk_label_new("Tab1");
gtk_widget_show(label);
page = gtk_frame_new("Content1");
gtk_widget_show(page);
gtk_notebook_append_page(GTK_NOTEBOOK(notebook), page, label);
/* notebook page 2 */
label = gtk_label_new("Tab2");
gtk_widget_show(label);
page = gtk_frame_new("Content2");
gtk_widget_show(page);
gtk_notebook_append_page(GTK_NOTEBOOK(notebook), page, label);
create_tab_menu(notebook);
And this is the content of the create_tab_menu() function to create the
context menu of the tab, that actually contains the action to be
triggered by the accelerator:
void create_tab_menu(GtkWidget *notebook)
{
GtkWidget *menu;
GtkBuilder *builder;
GSimpleActionGroup *actiongroup;
int i;
struct accel_map {
char *action;
const char * const accel[2];
};
/* define actions */
static GActionEntry tab_actions[] = {
{"test_action", test_cb, NULL, NULL, NULL, {}}
};
/* define accelerators */
static struct accel_map tab_accels[] = {
{"tab.test_action", {"t", NULL}}
};
/* define menu structure */
builder = gtk_builder_new();
gtk_builder_add_from_string(builder,
""
" "
" "
" "
" Test Action"
" tab.test_action"
" weather-clear-symbolic"
" "
" "
" "
"", -1, NULL);
/* create actiongroup and map actions */
actiongroup = g_simple_action_group_new();
g_action_map_add_action_entries(G_ACTION_MAP(actiongroup),
tab_actions,
G_N_ELEMENTS(tab_actions), NULL);
/* map accelerators to actions */
for (i = 0; i < G_N_ELEMENTS(tab_accels); i++)
gtk_application_set_accels_for_action(GTK_APPLICATION(app),
tab_accels[i].action, tab_accels[i].accel);
/* create new GtkMenu from GtkBuilder */
menu =
gtk_menu_new_from_model(G_MENU_MODEL(gtk_builder_get_object(builder,
"tab-menu")));
/* insert action group into menu */
gtk_widget_insert_action_group(menu, "tab",
G_ACTION_GROUP(actiongroup));
/* connect tab menu to right-click handler of notebook */
g_signal_connect(G_OBJECT(notebook), "button-press-event",
G_CALLBACK(context_cb), menu);
g_object_unref(builder);
}
And for completeness the right-click handler:
gboolean context_cb(GtkWidget *notebook, GdkEventButton *event,
gpointer data)
{
(void) notebook;
if (event->button == 3) {
gtk_menu_popup_at_pointer(GTK_MENU(data), (GdkEvent*)event);
return TRUE;
}
return FALSE;
}
However, I'm afraid I'm back on my own and just have to find where it
goes wrong in my application.
Thanks

I don't think adding accelerators to the labels is an option. Notebook pages are indexed from 0 and you can retrieve the index with gtk_notebook_get_current_page. Then de/increment with 1 and use gtk_notebook_set_current_page. Read up on [1] for the details on getting/settings notebook pages. ~infirit [1] https://developer.gnome.org/gtk3/stable/GtkNotebook.html ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
Accelerators for GtkNotebook to switch between pages
Hi list, I'm looking for a way to switch between the pages of a GtkNotebook using e.g. Left and Right. I searched the documentation from different angels but didn't found a obvious way how to accomplish that. Does somebody have a hint for me pointing into the right direction? Thank you verymuch in advance. - Alex ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
