> When the applet starts, a progress bar is displayed. When the applet finishes downloading, the progress bar disappears, leaving a gray box until the pivot toolkit loads the application. Even for the simpliest application displaying an empty window, pivot requires about 0.3 s to start (on Core2Duo 2.2 GHz), so the gray box effect can be easily seen. The gray box effect does not happen always, but in about half of the cases.
> Below I submit patch we made to the BrowserApplicationContext.java file. Seems like setting the applet's background to white and delaying the add(displayHost) call as late as possible does the trick:
> [code]
> 51a52
> > private boolean displayHostInstalled = false;
> 151c152,154
> < add(displayHost);
> ---
> >
> > // Don't add it now, add it later, to avoid ugly gray box:
> > //add(displayHost);
> 160c163,164
> < setBackground(null);
> ---
> > // Huh? WTF?
> > // setBackground(null);
> 191a196
> > installDisplayHostIfNeeded();
> 245a251,257
> > private void installDisplayHostIfNeeded() {
> > if (!displayHostInstalled) {
> > this.add(displayHost);
> > displayHostInstalled = true;
> > }
> > }
> >
> 247a260
> > this.setBackground(Color.white);

> > installDisplayHostIfNeeded();
> [/code]
