- * @addtogroup Ewl_Dnd
- * @section dnd_tut Tutorial
- *
- * In order to make DND handling easier for the end programmer, we've added a
- * simplification API to EWL. It currently supports receiving drops and some
- * limited dragging of widgets. Getting started is fairly simple, even for some
- * rather complicated widgets. As an example, I'll run through the DND support
- * added to the entry widget.
- *
- * The first step to setup DND support on a widget is to decide which MIME
types
- * are allowed and understood by the widget. The entry displays text, so
- * accepting the type "text/plain" is a safe choice. A NULL terminated list of
- * type strings is passed to the ewl_dnd_accepted_types_set, which enables DND
- * responses for the widget and helps to negotiate whether a drop will be
- * accepted at a given position.
- *
- * @code
- * const char *text_types[] = { "text/plain", NULL };
- *
- * ewl_dnd_accepted_types_set(EWL_WIDGET(e), text_types);
- * @endcode
- *
- * One key feature for DND support in the entry widget was to allow dragging
- * text to arbitrary positions within the visible text area. This is
- * accomplished by registering a callback for the EWL_CALLBACK_DND_POSITION
- * event on the entry widget.
- *
- * @code
- * ewl_callback_append(w, EWL_CALLBACK_DND_POSITION,
ewl_entry_cb_dnd_position, NULL);
- * @endcode
- *
- * When the mouse moves during a DND event over the specified entry w the
- * ewl_entry_cb_dnd_position function will be called. This function prototype
- * looks like all other EWL callback prototypes:
- *
- * @code
- * void ewl_entry_cb_dnd_position(Ewl_Widget *w, void *ev, void *data);
- * @endcode
- *
- * In this case, the void *ev parameter points to a Ewl_Event_Dnd_Position
- * struct, which contains more detailed information about the event. We can use
- * the coordinates from the event to position the cursor within our entry to
- * receive the dropped data. Since the entry widget inherits from the text
- * widget, the text calls are used directly on the widget to alter the entry
- * contents. The code to accomplish this is rather small when the extra
- * debugging information is removed:
- *
- * @code
- * void
- * ewl_entry_cb_dnd_position(Ewl_Widget *w, void *ev, void *data)
- * {
- * Ewl_Event_Dnd_Position *event;
- * Ewl_Text *txt;
- *
- * event = ev;
- * txt = EWL_TEXT(w);
- *
- * if (EWL_ENTRY(w)->editable && !DISABLED(w)) {
- * ewl_widget_focus_send(w);
- * ewl_text_cursor_position_set(txt,
ewl_text_coord_index_map(txt, event->x, event->y));
- * }
- * }
- * @endcode
- *
- * Once the cursor has been positioned, the only event we care about is
- * receiving the data from the drop. This is accomplished by using the
- * EWL_CALLBACK_DND_DATA callback which should also be placed on the entry
- * widget.
- *
- * @code
- * ewl_callback_append(w, EWL_CALLBACK_DND_DATA, ewl_entry_cb_dnd_data, NULL);
- * @endcode
- *
- * The function prototype for ewl_entry_cb_dnd_data is identical to
- * ewl_entry_cb_dnd_position, but the void *ev parameter is of type
- * Ewl_Event_Dnd_Data. Since we only registered to receive plain text data
- * dropped on the entry, we can insert the event data directly into the entry
at
- * the current cursor position.
- *
- * @code
- * void
- * ewl_entry_cb_dnd_data(Ewl_Widget *w, void *ev, void *data)
- * {
- * Ewl_Event_Dnd_Data *event;
- * Ewl_Text *txt;
- *
- * event = ev;
- * txt = EWL_TEXT(w);
- *
- * if (EWL_ENTRY(w)->editable && !DISABLED(w)) {
- * ewl_text_text_insert(txt, event->data,
- * ewl_text_cursor_position_get(txt));
- * }
- * }
- * @endcode
- *
- * Considering the complicated nature of the Xdnd protocol, we are able to
- * accomplish a considerable amount of work in very few lines of code. While
- * some flexibility is sacrificed to achieve this, almost all of the protocol
- * events are available for widgets to override as they please.
- *
- * Check back for followup information to handle drag events on widgets.
