mouseDrop property

void Function(InputEvent)? get mouseDrop

Gets or sets the function to execute when the user drops the selection in the background of the Diagram at the end of a DraggingTool drag-and-drop, not onto any GraphObjects.

If this property value is a function, it is called with an InputEvent. It is called within the transaction performed by the DraggingTool. By default this property is null.

For example, if you want to prevent the user from dropping Parts into the background of the diagram:

  myDiagram.mouseDrop = e => {
    myDiagram.currentTool.doCancel();
  }

Implementation

void Function(_i3.InputEvent)? get mouseDrop =>
    (_i3.InputEvent p0) => _i4.callMethod(
          _i4.getProperty(
            this,
            'mouseDrop',
          ),
          r'call',
          [
            this,
            p0,
          ],
        );

set mouseDrop (void value(InputEvent)?)

Implementation

set mouseDrop(void Function(_i3.InputEvent)? value) {
  _i4.setProperty(
    this,
    'mouseDrop',
    value == null ? _i5.undefined : _i4.allowInterop(value),
  );
}
