Refresh tool tip on figure [message #172302]

Hi,

Is there a way to force the tool tip of the figure to refresh?

I have a scenario that there are two figures: ChildFigure and ParentFigure
which both extends from IFigure, and ParentFigure contains ChildFigure. I
have a mouse motion listener, so that when the mouse is hover over
ChildFigure or ParentFigure, it gives the corresponding tool tip.

But if I hover over ChildFigure, it shows the tool tip for ChildFigure,
then the mouse is moved to the ParentFigure (without hovering other
figures in between), the tool tip still shows the ChildFigure one.

Thanks,
Diana

You must be doing something wrong. Maybe you didn't set up the listeners,
etc. properly.

Dynamically changing the tooltip of a *single* figure does not update the
displayed tooltip. But, as Pratik pointed out, changing the figure under
the mouse, and therefore the source of the tooltip, should work. Please
post test case code.

My scenario is that I have an edit part called MyEditPart, which has a
MyFigure. Inside the figure, it keeps track of its child figures (I'm
calling them marker figures, as they are marker-related decorators).

When I hover the mouse over MyFigure, it gives me the tool tip text for
MyFigure. And when I hover over one of the marker figure which is still
belong to MyFigure, it continues to show tool tip text for MyFigure.

I have two listeners:
1) on MyEditPart to listen to mouse motion on the figure (need to set it
on the edit part level, so it knows the model of the edit part)

protected MouseMotionListener fMouseMotionListener = new
MouseMotionListener.Stub() {
public void mouseHover(MouseEvent me)
{
if (me.getSource().equals(getFigure())) {
String hoverText =
HoverHelperManager.getHoverText(getPropertyMapModel());
if (hoverText == null)
getFigure().setToolTip(null);
else
getFigure().setToolTip(new Label(hoverText));

}
}
};

2) on MyFigure to listen to mouse motion on the marker figures

protected MouseMotionListener fMouseMotionListner = new
MouseMotionListener.Stub() {
public void mouseHover(MouseEvent me)
{
if (me.getSource() instanceof MarkerImageFigure) {
IMarker marker = ((MarkerImageFigure)me.getSource()).getMarker();
String hoverText = HoverHelperManager.getHoverText(marker);
if (hoverText == null)
setToolTip(null);
else
setToolTip(new Label(hoverText));
}

}
};

Thanks for your help.
