Wt

I am trying to display a button on top of a WPaintedWidget as a popup in jwt.

The documentation mentions setPopup and PositionScheme.Absolute
but there is no code example.

My code looks like this:

WVBoxLayout layout = new WVBoxLayout();
app.getRoot().setLayout(layout);
layout.addWidget(new GameWidget());

WPushButton button = new WPushButton("hello");
button.setPositionScheme(PositionScheme.Absolute);
button.setPopup(true);
layout.addWidget(button);

This creates a button in the lower half of the window.

I also tried app.getRoot().addWidget(button); - thinking that
maybe popup widgets can't be part of the layout. But this shows no
button at all.

I couldn't find a way to set the button location relative to parent, either.

Thanks for any help on this.
