动态改变RCP应用程序的标题

我们知道,Title是在ApplicationWorkbenchWindowAdvisor里面通过
????public?void?preWindowOpen()?{
????????IWorkbenchWindowConfigurer?configurer?=?getWindowConfigurer();
????????configurer.setInitialSize(new?Point(600,?500));
????????configurer.setShowCoolBar(false);
????????configurer.setShowStatusLine(true);
????????configurer.setShowProgressIndicator(true);
????????configurer.setTitle(xxx);
????}
来实现的,那么如何在运行时动态的更改它呢?
最开始一直在想如何获得
IWorkbenchWindowConfigurer,但是一点头绪都没有,后来到RCP新闻组里面问了一下,两个人给了回复,不过都不怎么满意,但其中一个给了我启示,他信中写道:
I've used the following technique:
public?static?void?changeAppTitle(String?newTitle)?{
????????Display?display?=?Display.getDefault();
????????if?(display?!=?null)?{
????????????????//?Look?at?all?the?shells?and?pick?the?first?one
????????????????//?that?is?a?workbench?window.
????????????????Shell?shells[]?=?display.getShells();
????????????????for?(int?i?=?0;?i?<?shells.length;?i++)?{
????????????????????????Object?data?=?shells[i].getData();
????????????????????????//?Check?whether?this?shell?points?to?the?Application?main?window's
shell:
????????????????????????if?(data?instanceof?IWorkbenchWindow)?{
????????????????????????????????shells[i].setText(newTitle);
????????????????????????????????break;
????????????????????????}
????????????????}
????????}
}
既然可以通过IWorkbenchWindow的Shell来设置标题,那么一切就好解决了。
在ActionBarAdvisor中初始化Action时,把WorkbenchWindow作为参数传入构造器中,然后在Action中就可以使用window.getShell().setText()了:)
