Event sent when a drag-and-drop is completed. More...
#include <qevent.h>
Inherits QEvent and QMimeSource.
Inherited by QDragMoveEvent.
When a widget accepts drop events, it will receive this event if it has accepted the most recent QDragEnterEvent or QDragMoveEvent sent to it.
The widget should use data() to extract data in an appropriate format.
Examples: desktop/desktop.cpp
Copy
- the default action. The source simply users the data
provided in the operation.
Link.
The source should somehow create a link to the location
specified by the data.
Move.
The source should somehow move the object from the location
specified by the data to a new location.
Private.
The target has special knowledge of the MIME type, which
the source should respond to similar to a Copy.
UserAction.
The source and target can co-operate using special
actions. This feature is not supported in Qt at this time.
The Link and Move actions only makes sense if the data is a reference, such as text/uri-list file lists
Call this to indicate that the action described by action() is accepted, not merely the default copy action. If you call acceptAction(TRUE), there is no need to also call accept(TRUE).
Returns the action which the target is requesting be performed with the data. If your application understands the action and can process the supplied data, call acceptAction(); if your application can process the supplied data but can only perform the Copy action, call accept().
This function is obsolete. It is provided to keep old programs working. We strongly advise against using it in new code.
Use QDropEvent::encodedData().
[virtual]
Returns a byte array containing the payload data of this drag, in format.
data() normally needs to get the data from the drag source, which is potentially very slow, so it's advisable to call this function only if you're sure that you will need the data in format.
The resulting data will have a size of 0 if the format was not available.
See also: format() and QByteArray::size().
Reimplemented from QMimeSource.
[virtual]
Returns a string describing one of the available data types for this drag. Common examples are "text/plain" and "image/gif". If n is less than zero or greater than the number of available data types, format() returns 0.
This function is provided mainly for debugging. Most drop targets will use provides().
See also: data() and provides().
Reimplemented from QMimeSource.
The opposite of accept().
Returns TRUE if the drop target accepts the event.
Returns the position where the drop was made.
[virtual]
Returns TRUE if this event provides format mimeType or FALSE if it does not.
See also: data().
Reimplemented from QMimeSource.
Sets the action. This is used internally, you should not need to call this in your code - the source decides the action, not the target.
If the source of the drag operation is a widget in this application, this function returns that source, otherwise 0. The source of the operation is the first parameter to to drag object subclass.
This is useful if your widget needs special behavior when dragging to itelf, etc.
