how to catch the double click event

[arun]

i have a requirement to catch the double click event. i am catching
right click too. but both event are getting mixed up. only right click
is working fine. Thsi may be because both event have same constant
field values. is ther eany way to distinguish these two?
Any help would be appreciated.

[Litty Preeth]

No the constants for both are different... Event.ONCLICK and Event.ONDBLCLICK



[arun]

no...actually i m mentioning about event.BUTTON_RIGHT and
event.ONDBLCLICK
Both having same value i.e.2 and i m using both in my application.

It doesn't matter that they have the same value, they are returned from 2 different fields in Event:

if(event.getButton() == Event.BUTTON_RIGHT)

if(event.getTypeInt() == Event.ONDBLCLICK)

Hope that helps

i tried this..but event.getTypeInt() is not capturing the doubleclick
event.is there any other way to capture double click?

Try this eg:

public class Home extends AbsolutePanel implements EntryPoint {

     

      public void onModuleLoad() {

            init();

      }

 

      private void init() {

            RootPanel.get().add(this);

            setHeight(Window.getClientHeight()+"px");

            DOM.setStyleAttribute(getElement(), "background", "#ADDFFF");

            Label lbl = new Label();

            DOM.setStyleAttribute(lbl.getElement(), "color", "blue");

            DOM.setStyleAttribute(lbl.getElement(), "font-weight", "bold");

            DOM.setStyleAttribute(lbl.getElement(), "font-size", "16px");

            lbl.setText("Right Click OR Double Click anywhere");

            this.add(lbl);

            sinkEvents(Event.ONMOUSEDOWN);

            sinkEvents(Event.ONDBLCLICK);

      }

     

      public void onBrowserEvent(Event event) {

            super.onBrowserEvent(event);

            switch (DOM.eventGetType(event)) {

            case Event.ONMOUSEDOWN:

                  if(DOM.eventGetButton(event) == Event.BUTTON_RIGHT)

                        Window.alert("You RIGHT CLICKED");

                  break;

            case Event.ONDBLCLICK:

                  Window.alert("You DOUBLE CLICKED");

                  break;

            }

      }

}
