unregistering the ContextMenuHandler does not work?
I assume you have sth like this:
class YourWidget extends Composite implements ContextMenuHandler {
HandlerRegistration registration;
public YourWidget(){
final HTML html =
new HTML("<div>Right-click here please
;)</div>");
Button setCustomMenuButton = new Button("Set Custom Menu");
Button setNativeMenuButton = new Button("Set Native Menu");
setCustomMenuButton.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
registration = addDomHandler(YourWidget.this,
ContextMenuEvent.getType());
}
});
setNativeMenuButton.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
registration.removeHandler();
}
});
FlowPanel mainPanel = new FlowPanel();
initWidget(mainPanel);
mainPanel.add(html);
mainPanel.add(setCustomMenuButton);
mainPanel.add(setNativeMenuButton);
}
@Override
public void onContextMenu(ContextMenuEvent event) {
final int x = event.getNativeEvent().getClientX() +
Window.getScrollLeft();
final int y = event.getNativeEvent().getClientY() +
Window.getScrollTop();
final PopupPanel popup = new PopupPanel(true, true);
popup.add(new HTML("my context menu"));
popup.setPopupPositionAndShow(new PositionCallback() {
@Override
public void setPosition(int offsetWidth,
int offsetHeight) {
popup.setPopupPosition(x, y);
}
});
}
}
