Detailed Description
Service called from the UI when some object is dropped into the UI. Usable for modifying drag&drop behaviors such as adding custom handlers for object types other than supported media files.Implement where needed; use ui_drop_item_callback_factory_t<> template to register, e.g. static ui_drop_item_callback_factory_t<myclass> g_myclass_factory.
Member Typedef Documentation
Reimplemented from service_base.
Member Function Documentation
| virtual bool ui_drop_item_callback::on_drop | ( | interface IDataObject * | pDataObject | ) | [pure virtual] |
Called when an object was dropped; returns true if the object was processed and false if not.
| virtual bool ui_drop_item_callback::is_accepted_type | ( | interface IDataObject * | pDataObject, | |
| DWORD * | p_effect | |||
| ) | [pure virtual] |
Tests whether specified object type is supported by this ui_drop_item_callback implementation. Returns true and sets p_effect when it's supported; returns false otherwise.
See IDropTarget::DragEnter() documentation for more information about p_effect values.
| static bool ui_drop_item_callback::g_on_drop | ( | interface IDataObject * | pDataObject | ) | [static] |
Static helper, calls all existing implementations appropriately. See on_drop().
| static bool ui_drop_item_callback::g_is_accepted_type | ( | interface IDataObject * | pDataObject, | |
| DWORD * | p_effect | |||
| ) | [static] |
Static helper, calls all existing implementations appropriately. See is_accepted_type().
