Implemented Interfaces
GtkToolPalette implements AtkImplementorIface, GtkBuildable and GtkOrientable.
Description
A GtkToolPalette allows you to add GtkToolItems to a palette-like container with different categories and drag and drop support.
A GtkToolPalette is created with a call to gtk_tool_palette_new().
GtkToolItems cannot be added directly to a GtkToolPalette -
instead they are added to a GtkToolItemGroup which can than be added
to a GtkToolPalette. To add a GtkToolItemGroup to a GtkToolPalette,
use gtk_container_add().

GtkWidget *palette, *group; GtkToolItem *item; palette = gtk_tool_palette_new (); group = gtk_tool_item_group_new (_("Test Category")); gtk_container_add (GTK_CONTAINER (palette), group); item = gtk_tool_button_new_from_stock (GTK_STOCK_OK); gtk_tool_item_group_insert (GTK_TOOL_ITEM_GROUP (group), item, -1); |
The easiest way to use drag and drop with GtkToolPalette is to call
gtk_tool_palette_add_drag_dest() with the desired drag source palette
and the desired drag target widget
. Then gtk_tool_palette_get_drag_item()
can be used to get the dragged item in the “drag-data-received”
signal handler of the drag target.
