How to make a custom drag and drop tracker image [message #449221] Wed, 19 January 2005 18:12 Go to next message

Hi,

I want to drag a tree item to the editor. I want to tracker image showing
the actual size of the object being dropped. Just like when you move a
control, it shows the tracker with the actual size of the object moved.

Could someone tell me how to do it or which classes I should look at?

Thanks,

Kevin

This is not currently supported with DragSource/DropTarget. This is a
requirement that I am investigating but I can not give a date when this will
be available.

You could use org.eclipse.swt.widgets.Tracker and implement your own
DragDetect listener.

Could you tell me how it can be done? I look at the DragSource.drag
function, it uses the COM.DoDragDrop to do the drag drop. I don't know
where I can set the Tracker.

Thanks.

You can not do it using DragSource. You must implement your own mouse event
handlers to simulate drag and drop. This is how Eclipse allows you to drag
views around the workbench. It does not use DragSource and DropTarget, it
uses DragDetect, MouseEnter, MouseMove, MouseExit events etc.

Hi Veronika,

I cannot find the DragDetect function in SWT. Could you tell me which file
I should look at?

Thanks.

Kevin

control.addListener(SWT.DragDetect, new Listener() {
public void handleEvent(Event e) {
// code to start using Tracker.
}
});
