Toggle Button on the EditorToolbar [message #109935]

I added a button to my editors toolbar just like in the Logic example.. by
extening RetargetAction.

This button functions like a push button; you push it and it pops back out
again...

I want a Toggle button - click once and it gets depressed, click again and
it pops out again.

If you create a button using an editor extension point, I think you can
specify that you want a toggle style button... the constructor for the
Action class also allows a style parameter but this is not visible at
RetargetAction.

So am I supposed to implement the toggle logic manually but keeping the
button pressed (how do I do this) depending on some state variables ?

Thanks,
Brian.

I wonder if both the retarget action, and the action handler (another
action) both have to have the checkbox style? Seems redundant.

I don't know if I'm missing something obvious here; but RetargetAction has a
single constructor which takes two String arguments. You've mentioned a
third integer argument ... to RetargetAction ?

Aah, yes, the comment for that constructor says that it was introduced in
3.0. So, I am guessing you have a version older than that. In the older
version, you might be able to extend RetargetAction and specify the style:
IAction.AS_CHECK_BOX. Or maybe just specifying this style on your original
action would do the trick.

Sorry for not mentioning my Eclipse version; but I checked in Eclipse 3M5
and it wasn't there ...

So I guess it was added in the recently released M6 ?? (hooray ! for once I
acutally must use
bleeding edge technology ;)

But if I use the new constructor ... then I suppose my plugin will not work
perfectly on 2.1.1 platforms anymore ? So far I have been developing using
Eclipse 3M2, but my users use the 2.1.2 platforms and no problems have come
up...

Specifiing the style for my original action faces the same problem as the
RetargetAction. I've extended EditPartAction and again the style can only
be specified in the Action class constructor. The classes subclassing Action
leave out the style parameter. Will check in M6 though. :(

Thanks & Merry Christmas,
Brian.

calling setValue(false) or something like that has the side-effect of
setting the AS_CHECK_BOX style.
I'm not sure that it makes sense for the RetargetAction to have any style at
all. Ideally it should inherit the style from it's action handler. But,
alas the limitation of SWT require you to set the SWT.CHECK style at the
time when MenuItem is constructed. So I guess you probably could call a
bogus setValue. Can you find examples of boolean retarget action (JDT
perhaps?) in 2.1 or whatever version you are on?

Thanks Randy,
Calling setChecked(false) in the RetargetAction does make it a check_box
styled button.

I agree, the retarget action should inherit it's properties from the action
handler - the current implementation is quite ambiguou - in M6, I believe
you can set the style of the RetargetAction directly as Pratik says; but
that increases the ambiguity when both actions have different styles.

Brian.
