# `wxBitmapDataObject` [🔗](https://github.com/garazdawi/otp/blob/lukas/shell_docs/fix-bugs/lib/wx/src/gen/wxBitmapDataObject.erl#L58) `m:wxBitmapDataObject` is a specialization of `m:wxDataObject` for bitmap data. It can be used without change to paste data into the `m: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](https://docs.wxwidgets.org/3.2/overview_dnd.html#overview_dnd) * `m:wxDataObject` * `m:wxFileDataObject` * `m:wxTextDataObject` * `m:wxDataObject` This class is derived, and can use functions, from: * `m:wxDataObject` wxWidgets docs: [wxBitmapDataObject](https://docs.wxwidgets.org/3.2/classwx_bitmap_data_object.html) # `wxBitmapDataObject` ```erlang -type wxBitmapDataObject() :: wx:wx_object(). ``` # `destroy` ```erlang -spec destroy(This :: wxBitmapDataObject()) -> ok. ``` Destroys the object # `getBitmap` ```erlang -spec getBitmap(This) -> wxBitmap:wxBitmap() when 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 `m:wxClipboard`. # `new` ```erlang -spec new() -> wxBitmapDataObject(). ``` # `new` ```erlang -spec new([Option]) -> wxBitmapDataObject() when Option :: {bitmap, wxBitmap:wxBitmap()}; (Bitmap) -> wxBitmapDataObject() when Bitmap :: wxBitmap:wxBitmap(). ``` Constructor, optionally passing a bitmap (otherwise use `setBitmap/2` later). # `setBitmap` ```erlang -spec setBitmap(This, Bitmap) -> ok when 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. --- *Consult [api-reference.md](api-reference.md) for complete listing*
