Thanks for the suggestion. Sounded what I needed but when I tried it,
didn't have the effect I hoped for.
The following still gives an exception (in the constructor of a Widget):
qx.ui.core.queue.Manager.flush();
var container = this.getContentElement().getDomElement();
container.style.lineHeight="normal"; // Exception: cannot read property
style of null
...
So I still have to use (making it asynchronous):
qx.ui.core.queue.Manager.flush();
this.addListenerOnce("appear", () => {
var container = this.getContentElement().getDomElement();
container.style.lineHeight="normal";
....
})
Is there somehting else I'm missing? I just want the widget to create its
underlying DOM elements and not delay it.
