GI.Gtk.Objects.ToolPalette

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

A ToolPalette is created with a call to toolPaletteNew.

GtkToolItems 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 containerAdd.

C code

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 toolPaletteAddDragDest with the desired drag source palette and the desired drag target widget. Then toolPaletteGetDragItem can be used to get the dragged item in the Widget::drag-data-received signal handler of the drag target.

C code

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);

Properties

iconSize

The size of the icons in a tool palette. When this property is set, it overrides the default setting.

This should only be used for special-purpose tool palettes, normal application tool palettes should respect the user preferences for the size of icons.

Since: 2.20

constructToolPaletteIconSize :: IsToolPalette o => IconSize -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “icon-size” property. This is rarely needed directly, but it is used by new.

getToolPaletteIconSize :: (MonadIO m, IsToolPalette o) => o -> m IconSize

Get the value of the “icon-size” property. When overloading is enabled, this is equivalent to

get toolPalette #iconSize

setToolPaletteIconSize :: (MonadIO m, IsToolPalette o) => o -> IconSize -> m ()

Set the value of the “icon-size” property. When overloading is enabled, this is equivalent to

set toolPalette [ #iconSize := value ]

iconSizeSet

Is True if the ToolPalette:icon-size property has been set.

Since: 2.20

constructToolPaletteIconSizeSet :: IsToolPalette o => Bool -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “icon-size-set” property. This is rarely needed directly, but it is used by new.

getToolPaletteIconSizeSet :: (MonadIO m, IsToolPalette o) => o -> m Bool

Get the value of the “icon-size-set” property. When overloading is enabled, this is equivalent to

get toolPalette #iconSizeSet

setToolPaletteIconSizeSet :: (MonadIO m, IsToolPalette o) => o -> Bool -> m ()

Set the value of the “icon-size-set” property. When overloading is enabled, this is equivalent to

set toolPalette [ #iconSizeSet := value ]

toolbarStyle

The style of items in the tool palette.

Since: 2.20

constructToolPaletteToolbarStyle :: IsToolPalette o => ToolbarStyle -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “toolbar-style” property. This is rarely needed directly, but it is used by new.

getToolPaletteToolbarStyle :: (MonadIO m, IsToolPalette o) => o -> m ToolbarStyle

Get the value of the “toolbar-style” property. When overloading is enabled, this is equivalent to

get toolPalette #toolbarStyle

setToolPaletteToolbarStyle :: (MonadIO m, IsToolPalette o) => o -> ToolbarStyle -> m ()

Set the value of the “toolbar-style” property. When overloading is enabled, this is equivalent to

set toolPalette [ #toolbarStyle := value ]
