Activate actionSets, commands & bindings plugin before workbench startup [message #462300]

Hi,

How do I load/activate the plugins for org.eclipse.ui.actionSets, commands, and bindings before workbench is start-up?

I can't use org.eclipse.ui.startup, earlyStartup() as it is only executed after workbench has been started.

I tried to access IConfigurationElements of org.eclipse.ui.actionSets, commands, and bindings to get Eclipse to load their plugins. But it does not seem to work.

Any help on this subject is much appreciated.

Thanks. Rgds.

1) you can't
2) don't

Even early startup is supposed to initialize data (or re-establish io
connections or database information, etc) ... not to pre-load UI elements.

:-)

OK, now that I've covered the best practices, what behaviour are you
trying to accomplish that you would like to load action set <actions/>
or commands and keybindings ... and why do you think you need them
before the workbench itself is up?

Also note, in RCP there are pre and post methods on WorkbenchAdvisor and
WorkbenchWindowAdvisor ... but they usually depend on the workbench
being up.

Until the workbench comes up, none of the extension points have been
read. In some cases, the extension points are not read until a
workbench window comes up.

Thks for the reply.

My project needs to open a login dialog box to allow users to input their user ID and password. After the user has input the data, the system will perform some security checks before loading the UI workbench. I'm not sure why security checks must be done before loading the UI workbench but it is a key requirement for my project team.

The users can only input the data using a virtual keyboard on a touchscreen. Therefore, I need to use the actionSet, command and binding extension points to capture key events on the virtual keyboard to display the correct alphabets & digits on the screen.

As such, I need to load the actionSet, command, and binding extension points before the UI workbench is opened.

You ought to look into Eclipse-JAAS, which also has an associated talk scheduled for EclipseCon this year. It aims to do something similar.

Note that the splash screen and dialog box asking which workbench you want to use does essentially this already, but IIRC doesn't use the actionSet or similar to deal with user interaction. Indeed, I'm not sure it makes sense to think about using actionSets prior to the workspace UI's initialisation.

My project is using Eclipse-JAAS but it's being handled by another team mate. So I'm not really sure about the specifics.

I'm wondering what is the specific reason for the inability to load actionSet, command, and binding extension points before workbench is being loaded?

Just curious to know.

Because they depend on the workbench being up? It's like complaining that you can't move anywhere in a car before turning it on.

They're a function of the working workbench/workbench window ... and in
the actionSet case, they are tied specifically to a menu item or toolbar
item ... you don't initialize a toolbar item until you have a toolbar to
point to ...

That being said, none of that is necessary. Your virtual keyboard is
just an input device. Does it not generate key pressed events? Any
dialog you put up should get them already, and of course you can add a
filter to the display to capture global key press events as they go through.

eclipse-jaas must already do part of the login work and get this input, no?
