Hi,

how to register a custom ISaveHandler and IWindowCloseHandler to an Eclipse RCP4 Application?

I created custom ISaveHandler and a custom IWindowCloseHandler to alter the close behavior of Parts and the Window.

Currently i add this Handlers to the MWindow context by injection the MWindow to every Part that is created and than create and add the Handlers to the context. This is definitely the the wrong attempt but i have no idea how to add the Handers directly to the Model!?

Thanks in advance Smile

The way it was shown just a few topics before yours:

If I understood this correctly:
-it seems you already know how to do this;
-no, I am not aware of any way you can set these handlers through application model;
-you only need to set these handlers in MWindow's context once;
-unless, you want different handlers for different occasions;
-afaik (at least in Juno) it is not possible to register close/save handler to individual part.

Hi,

thanks for the quick answer. My problem is that i don't understand how to register the handler only once. I guess i need something that get's notified when my window is created. After this i can add the handler to the context of the window.

The solution provided in http://www.eclipse.org/forums/index.php/mv/msg/369989/966231/#msg_966231 shows how to add the handler but does't show how to get the QuitProcessor started up. As i replyed to that post i have no idea what to do with the QuitProsessor? Sad

-I only want to use one handler.

Thanks

Ok, now I see. I hadn't noticed that you've re-opened another thread, when I replied.

You can read about processors in Lars Vogel's tutorial, google: vogella Eclipse 4 Modularity.

Hi,

my problem persists. If i try to add the ISaveHandler or IWindowCloseHandler via Processor in an add on, i have the problem that the MWindow does not jet have a context. I get a null on MWindow.getcontext.

Using a Processor to change the context seems to early ?!?

Thanks Smile
