Question

I have a Composite which I will place in an Absolute Panel, I want to be able to specify the location coordinates of the composite and place it at that location in the absolute panel.

Also, at run time, sometime I will have to change the location coordinates of the Composite and move it.

I could have use a grid or other panel but while moving the composit, I want to place a move animation, that’s why I’m using an absolute panel.

How to specify the coordinates of the composite before placing it in the absolute panel?

the composite:

public class SlotView extends Composite
{
...
}

Answer 1

AbsolutePanel.setWidgetPosition() will change the location of a Widget displayed inside of an AbsolutePanel. This is limited only to using pixel-based offsets.

A more robust solution is to use a LayoutPanel, which supports the use of font- or box-relative positions. LayoutPanel also has support for animating transitions.
