选择侦听器何时在视图中注册？

Question

I have a View in my RCP application that draws some things and it's created when the user clicks a certain Toolbar action. The View implments the ISelectionProvider and when some objects in the view are clicked their properties are shown in the property view.

The problem is when I programmatically show the view through getActivePage.showView("viewid") in the run() method of the action it seems that no listeners are registered so nothing is shown in the properties view.

As soons as a hide the view by pressing some other view to appear and then I open it again the listeners are registered and the properties are shown.

So in what method are these listeners registered that is not called with the showView command?

Answer 1

我认为如果视图具有焦点，则宣布选择，在显示之前，请尝试以编程方式设置焦点。

Answer 2

It's triggered when the part is activated. Try

PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().showView("myViewId", null, IWorkbenchPage.VIEW_ACTIVATE)
