Description:

[ Version ( since = "2.20" ) ]
public class ToolPalette : Container, Implementor, Buildable, Orientable, Scrollable

A ToolPalette allows you to add ToolItems to a palette-like container with different categories and drag and drop support.

A ToolPalette is created with a call to ToolPalette.

ToolItems cannot be added directly to a ToolPalette - instead they are added to a ToolItemGroup which can than be added to a ToolPalette. To add a ToolItemGroup to a ToolPalette, use 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 (NULL, _("_Open"));
gtk_tool_button_set_icon_name (GTK_TOOL_BUTTON (item), "document-open");
gtk_tool_item_group_insert (GTK_TOOL_ITEM_GROUP (group), item, -1);

The easiest way to use drag and drop with ToolPalette is to call add_drag_dest with the desired drag source palette and the desired drag target widget. Then get_drag_item can be used to get the dragged item in the drag_data_received signal handler of the drag target.

static void
passive_canvas_drag_data_received (GtkWidget *widget,
GdkDragContext *context,
gint x,
gint y,
GtkSelectionData *selection,
guint info,
guint time,
gpointer data)
{
GtkWidget *palette;
GtkWidget *item;

// Get the dragged item
palette = gtk_widget_get_ancestor (gtk_drag_get_source_widget (context),
GTK_TYPE_TOOL_PALETTE);
if (palette != NULL)
item = gtk_tool_palette_get_drag_item (GTK_TOOL_PALETTE (palette),
selection);

// Do something with item
}

GtkWidget *target, palette;

palette = gtk_tool_palette_new ();
target = gtk_drawing_area_new ();

g_signal_connect (G_OBJECT (target), "drag-data-received",
G_CALLBACK (passive_canvas_drag_data_received), NULL);
gtk_tool_palette_add_drag_dest (GTK_TOOL_PALETTE (palette), target,
GTK_DEST_DEFAULT_ALL,
GTK_TOOL_PALETTE_DRAG_ITEMS,
GDK_ACTION_COPY);
