blackberry field like the OS animated busy clock
Is it possible to use Blackberry's native loading icon(progress bar) from code?
I want to display 开发者_Go百科a progressbar like above when I call a webservice. This progress bar appears when installing an app onto a BlackBerry device.
Most of the images and resources used in standard BlackBerry applications can be found in "Program Files" of BlackBerry Theme Studio.
That said, as Richard mentioned, for BlackBerry users this particular clock means "garbage collector is running", which is associated with slowdowns, battery drainage and possible need for re-boot. The hour glass is even worse, it is called "hour glass of doom" or "hour glass of death" and often means re-installing the OS.
I would recommend creating very simple field with paint method showing actual downloading progress. GaugeField might help you here, see this discussion about how to use it.
