DnD lag in DropControllerCollection

[Rhystic]

Hi Fred,

I just came across dnd in my GWT project and tried to use this awesome library in my project. However I've encounter a problem with a very noticeable lag in the drag-drop flow when I'm using DropControllerCollection with multiple DropController on SimplePanel.

I copied the entired class out and try to figure out which part of the code was causing the lag and I found that it was the resetCache method that causing the lag.

Now I'm somewhat stuck in the middle and hope anyone that has encountered this problem before could share some opinion on how to solve this problem :)

Thanks a bunch!

This could be a silly remark but, when you are in gwt development mode, EVERYTHING is extremely slow.

Try compiling and running your app in hosted mode.

Ahhh!!

Silly me, yeah the app run smoothly in hosted mode x_x omg! Was getting heart attack wondering why the app is so laggy in dev mode and used whole day trying to debug x(

Thanks!

Hi,

I faced another problem regarding the PickupDragController:

PickupDragController bodyDragController = new PickupDragController(bodySelectionPane,false);

bodyDragController.setBehaviorMultipleSelection(false); 

bodyDragController.setBehaviorDragStartSensitivity(1);

Image test = new Image(GWT.getModuleBaseURL()+"images/NoImg.jpg");

PushButton test2 = new PushButton(test);

test2.setStylePrimaryName("nullButton");

bodyDragController.makeDraggable(test2);

test2.addClickHandler(new ClickHandler()

{   @Override

    public void onClick(ClickEvent event)

    {    System.out.println("Clicked");

    }

});

The onClick event does no fire even i set the DragStartSensitivity to > 0 as suggested... Any idea?

Uhh nevermind, I found an alternate work around, instead of using pushbuttons, i used image with click listener, works well :)

I was wondering why you didn't do that in the first place =)
