Sharing zoom action between different editors [message #151907]

Hi,

I have made a MultiPageEditor and one of it`s page is a GEF editor. This
page supports the zoomIn and zoomOut actions. When I open the editor this
actions are added to the toolBar of the workbench, and there isn`t any
problem to use them.

The problem is that when I open a second file with the same editor (the
two files are now opened) the second editor adds another zoomIn and
zoomOut aciton to the toolBar. And now I have two zoomIn actions and two
zoomOut actions. The first ones are working with the first opened file and
the second ones are working with the second file.

I want to have only one zoomIn action and one zoomOut action and to share
them acrossed the opened files. I now that maybe I can put them az
globalActions, but zoom actions are constructed az follows

IAction zoomIn = new ZoomInAction(root.getZoomManager());

and here root is the rootEditPart. So if they are globalActions I must
somehow get them from the toolBar and change their zoomManagers. But I
can`t see a way to set the zoomManager of an zoomAction. The only way to
do this is to construct a new instance of the zoomAction, to remove the
old action and to put the new one. But this operations must be done not
only when I open a new file with my editor but even more - when I switch
between the open files.

The problem gets bigger becouse my editor isn`t a GraphicalEditor and
there isn`t such a thing like ActionRegistry. My editor is a MultiPage
Editor and only one of its pages is a GEF page.

I don`t know whether this is a good solution but I thought that I could
"add" the ActionRegistry to the MultiPageEditor myself but it seems to be
not so simple, and I am not sure if this will work.

Could somebody help me find a way to solve my problem, and to share the
actions between opend files.

Thank you.

You need to use retarget actions (ZoomInRetargetAction and
ZoomOutRetargetAction in this case).
