Constructor & Destructor Documentation
This constructor requires that you must call SetData() later.
Note that the type of iconCopy and subsequent parameters differs between different ports: these are cursors under Windows and OS X but icons for GTK. You should use the macro wxDROP_ICON() in portable programs instead of directly using either of these types.
Availability: only available for the
wxMSW,
wxOSX ports.
- Parameters:
-
win | The window which initiates the drag and drop operation. |
iconCopy | The icon or cursor used for feedback for copy operation. |
iconMove | The icon or cursor used for feedback for move operation. |
iconNone | The icon or cursor used for feedback when operation can't be done. |

- Parameters:
-
data | The data associated with the drop source. |
win | The window which initiates the drag and drop operation. |
iconCopy | The icon or cursor used for feedback for copy operation. |
iconMove | The icon or cursor used for feedback for move operation. |
iconNone | The icon or cursor used for feedback when operation can't be done. |

This is the wxGTK-specific version of the constructor taking wxIcon instead of wxCursor as the other ports.

iconCopy | The icon or cursor used for feedback for copy operation. |
iconMove | The icon or cursor used for feedback for move operation. |

Member Function Documentation
virtual wxDragResult wxDropSource::DoDragDrop |
( |
int |
flags = wxDrag_CopyOnly | ) |
[virtual] |
Starts the drag-and-drop operation which will terminate when the user releases the mouse.
Call this in response to a mouse button press, for example.
- Parameters:
-
flags | If wxDrag_AllowMove is included in the flags, data may be moved and not only copied as is the case for the default wxDrag_CopyOnly. If wxDrag_DefaultMove is specified (which includes the previous flag), moving is not only possible but becomes the default operation. |
- Returns:
- The operation requested by the user, may be wxDragCopy, wxDragMove, wxDragLink, wxDragCancel or wxDragNone if an error occurred.
Returns the wxDataObject object that has been assigned previously.
virtual bool wxDropSource::GiveFeedback |
( |
wxDragResult |
effect | ) |
[virtual] |
You may give some custom UI feedback during the drag and drop operation by overriding this function.
It is called on each mouse move, so your implementation must not be too slow.
- Parameters:
-
- Returns:
- false if you want default feedback, or true if you implement your own feedback. The return value is ignored under GTK.
Set the icon to use for a certain drag result.
- Parameters:
-
res | The drag result to set the icon for. |
cursor | The icon to show when this drag result occurs. |
Availability: only available for the
wxMSW,
wxOSX ports.
Sets the data wxDataObject associated with the drop source.
This will not delete any previously associated data.
Set the icon to use for a certain drag result.
- Parameters:
-
res | The drag result to set the icon for. |
icon | The icon to show when this drag result occurs. |
Availability: only available for the
wxGTK port.
