Method Details

run

boolean run(@Nullable ContextMenu contextMenu,
 @Nullable WebHitTestResult hitTestResult)

Emitted before a context menu is displayed in the UI Process to give the application a chance to customize the proposed menu, build its own context menu or pass user data to the UI Process. This signal is useful when the information available in the UI Process is not enough to build or customize the context menu, for example, to add menu entries depending on the node at the coordinates of the hitTestResult. Otherwise, it's recommended to use WebKitWebView::context-menu signal instead.
