Functions for wxBitmapDataObject class


wxBitmapDataObject is a specialization of wxDataObject for bitmap data. It can be used without change to paste data into the wxClipboard or a wxDropSource (not implemented in wx). A user may wish to derive a new class from this class for providing a bitmap on-demand in order to minimize memory consumption when offering data in several formats, such as a bitmap and GIF.

This class may be used as is, but getBitmap/1 may be overridden to increase efficiency.

See: Overview dnd, wxDataObject, wxDataObjectSimple (not implemented in wx), wxFileDataObject, wxTextDataObject, wxDataObject

This class is derived (and can use functions) from: wxDataObject

Data Types

wxBitmapDataObject() = wx:wx_object()


new() -> wxBitmapDataObject()
new(Options :: [Option]) -> wxBitmapDataObject()
new(Bitmap) -> wxBitmapDataObject()

Bitmap = wxBitmap:wxBitmap()

Constructor, optionally passing a bitmap (otherwise use setBitmap/2 later).

getBitmap(This) -> wxBitmap:wxBitmap()

This = wxBitmapDataObject()

Returns the bitmap associated with the data object.

You may wish to override this method when offering data on-demand, but this is not required by wxWidgets' internals. Use this method to get data in bitmap form from the wxClipboard.

setBitmap(This, Bitmap) -> ok

This = wxBitmapDataObject()
Bitmap = wxBitmap:wxBitmap()

Sets the bitmap associated with the data object.

This method is called when the data object receives data. Usually there will be no reason to override this function.

destroy(This :: wxBitmapDataObject()) -> ok

Destroys the object.
