A `tm-edit-bitmap-operation` invokes one of the available operations on a __surrounding__ bitmap editor. Therefore the message has to be dispatched within the editor in order for it to catch it. The following properties on the `event` object are required:
|
|
|
|
|!Name |!Description |
|
|
|param |Name of the operation to be executed, see ''below'' for a list of possible operations |
|
|
|//{any other params}// |Any other parameters are made available as variables within the context of the widget message. |
|
|
|
|
|
|
The `tm-edit-bitmap-operation` message is usually generated by a ButtonWidget or an [[ActionWidget|ActionWidgets]] and is handled by the surrounding bitmap editor.
