Hi everyone,
for a private (yet) project, I need a GtkIconView, which can display a
GtkCheckButton in a corner of every icon or before/behind the label -
kinda like the idea of the plus/minus signs on every icon in the dolphin
file manager from KDE4. I first tried to achieve the functionality by
way of GtkCellRendererToggle and gtk_cell_layout_pack_end, but was not
able to make the check box clickable or when I set "mode" to
GTK_CELL_RENDERER_MODE_EDITABLE my app crashed with:
(app:5890): Gtk-CRITICAL **: gtk_widget_set_parent_window: assertion
`GTK_IS_WIDGET (widget)' failed
(app:5890): Gtk-CRITICAL **: gtk_widget_set_parent: assertion
`GTK_IS_WIDGET (widget)' failed
(app:5890): Gtk-CRITICAL **: gtk_cell_editable_start_editing: assertion
`GTK_IS_CELL_EDITABLE (cell_editable)' failed
(app:5890): Gtk-CRITICAL **: gtk_widget_grab_focus: assertion
`GTK_IS_WIDGET (widget)' failed
(app:5890): GLib-GObject-WARNING **: invalid (NULL) pointer instance
(app:5890): GLib-GObject-CRITICAL **: g_signal_connect_data: assertion
`G_TYPE_CHECK_INSTANCE (instance)' failed
I had a look at the implementation of GtkCellRendererPixbuf and
GtkCellRendererToggle, but since I don't have much experience with Gtk+
and have not developed a custom widget with it yet, I couldn't even
decide which one to subclass. So instead of re-inventing the wheel, I'd
like to see if someone else has it already rolling...
So if someone has useful pointers or knows an open source project with
an already working implementation, I'd appreciate a nudge in that
direction. Thanks in advance!
Best regards,
Todor
