ToolPaletteRef

public struct ToolPaletteRef : ToolPaletteProtocol, GWeakCapturing

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().

(C Language Example):

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 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 GtkWidget::drag-data-received signal handler of the drag target.

(C Language Example):

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);

CSS nodes

GtkToolPalette has a single CSS node named toolpalette.

The ToolPaletteRef type acts as a lightweight Swift reference to an underlying GtkToolPalette instance. It exposes methods that can operate on this data type through ToolPaletteProtocol conformance. Use ToolPaletteRef only as an unowned reference to an existing GtkToolPalette instance.

  • ptr
    Untyped pointer to the underlying `GtkToolPalette` instance.
    

    For type-safe access, use the generated, typed pointer tool_palette_ptr property instead.

    Declaration

    Swift

    public let ptr: UnsafeMutableRawPointer!
