Struct gtk::ToolPalette [−][src]
pub struct ToolPalette(_);
Expand description
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 new()
.
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 ContainerExt::add()
.
⚠️ The following code is in C ⚠️
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
ToolPaletteExt::add_drag_dest()
with the desired drag source palette
and the desired drag target widget
. Then ToolPaletteExt::drag_item()
can be used to get the dragged item in the signal::Widget::drag-data-received
signal handler of the drag target.
⚠️ The following code is in C ⚠️
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);
