ProgressBar，進度條，是ProgressIndicator的簡化版本。大多數情況下推薦使用ProgressIndicator。如果你決定直接使用ProgressBar，需要手動改變此bar的外觀。如下
//Style can be SMOOTH, HORIZONTAL, or VERTICAL
ProgressBar bar = new ProgressBar(parent, SWT.SMOOTH);
bar.setBounds(10, 10, 200, 32);
bar.setMaximum(100);
...
for(int i = 0; i < 10; i++) {
//Take care to only update the display from its
//own thread
Display.getCurrent().asyncExec(new Runnable() {
public void run() {
//Update how much of the bar should be filled in
bar.setSelection((int)(bar.getMaximum() * (i+1) / 10));
}
});
}
setSelection()causes the widget to be updated every time.This behavior is unlike that of ProgressIndicator or ProgressMonitorDialog,which will update the display only if it has changed by an amount that will be visible to the end user.
