Re: Having problems with getOffsetWidth() accuracy?

The safest way to read this information is to read it inside a Scheduler.get().scheduleDeferred() command.

Hi,

I'm using firefox 17. I'm trying to measure the width of a FlowPanel instance. It seems to always be off by about 5 or 6 pixels. I'm doing it like this:

    FlowPanel fp = new FlowPanel();

    fp.getElement().getStyle().setProperty("maxWidth", 300);

    fp.getElement().getStyle().setProperty("fontSize", 18);

    fp.getElement().setInnerText("hello");

    RootPanel.get().add(fp);

    int width = fp.getOffsetWidth(); // <-- not accurate

Is this not the correct way to do it? Is there some additional layout pass that happens after adding a panel which alters its size?

Thanks
