Select a tab while drag&drop

[michalg]

I would like to get the following scenario:
The user has a TabSet with two Tabs: say Department and Persons. He drags a person from the second Tab which displays persons list. Then, he drag-over the TabBar to the title of the first (Department), which is not selected yet.
Now, I would like the TabSet (or TabBar) to select Department tab and allow user drop a Person here.
Is it doable? Any hints?

Should be a standard drag and drop interaction - add some drop-related event handlers to the TabSet (dropOver, etc) which call selectTab if the mouse hovers over a particular tab for a moment.

I also think that this should be a standard drag&drop interaction for TabSets.

Meantime I ended with this code:

        //the following drop handling let the user select a tab while drag&drop
        this.setCanAcceptDrop(true);
        this.addDropMoveHandler(new DropMoveHandler() {

            public void onDropMove(DropMoveEvent event) {
                TabSet thisTS = (TabSet) event.getSource();
                for (Tab tab : thisTS.getTabs()) {
                    StatefulCanvas liveWidget = (StatefulCanvas) tab.getTabCanvas();
                    if (event.getX() > liveWidget.getPageLeft() && event.getX() < liveWidget.getPageRight()
                            && event.getY() > liveWidget.getPageTop() && event.getY() < liveWidget.getPageBottom()) {
                        thisTS.selectTab(tab);
                    }
                }
                event.cancel();
            }
        });

Corrections or improvements are welcome.

Thanks,
