contextClick property

void Function(InputEvent)? get contextClick

Gets or sets the function to execute when the user single-secondary-clicks on the background of the Diagram. This typically involves a mouse-down followed by a prompt mouse-up at approximately the same position using the right (secondary) mouse button. This property is used by the ClickSelectingTool when the user clicks on no object. The function is called in addition to the DiagramEvent that is raised with the name "BackgroundContextClicked".

If this property value is a function, it is called with an InputEvent. By default this property is null.

If you do provide a function that makes changes to the diagram or to its model, you should do so within a transaction -- call #startTransaction and #commitTransaction, or call #commit.

Implementation

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

set contextClick (void value(InputEvent)?)

Implementation

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