* @Title: GtkToolPalette
|
|
*
|
|
* 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().
|

|
* GtkToolItem *item;

|
* 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.
