Save handler when editing files not in workspace using eclipse default editor [message #325737]

Hi,

Here's the code that would open an external file (meaning file that does
not exist in my workspace) and then edit it using eclipse default editor.

File fileToOpen = new File("external_file.xml");

if (fileToOpen.exists() && fileToOpen.isFile()) {
IFileStore fileStore =
EFS.getLocalFileSystem().getStore(fileToOpen.toURI());
IWorkbenchPage page =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage();

try {
IDE.openEditorOnFileStore( page, fileStore );
} catch ( PartInitException e ) {
//Put your exception handler here if you wish to
}
} else {
//Do something if the file does not exist
}

I wanted to execute a code when the user saves the document by ctrl+s or
file->save or by pressing the save icon.

How should I do this?

I tried

editorPart.getEditorSite().getActionBars().setGlobalActionHa ndler(
ActionFactory.SAVE.getId(), myaction );

where myaction is an instance of a class that extends Action class and
override s the run method.

But then the run method will never be executed once the document is saved.

I also believe the resource change listener can't be of help either
because it's would only track down workspace resources.

What should I do? Please enlighten me gurus.

You could add an IExecutionListener to the ICommandService ... when the
save command is executed it fires events. The command id is
org.eclipse.ui.file.save

Check out some of the links in my sig for information on the command
framework.

Thanks Paul.

Adding IExecutionListener to the ICommandService worked. However, clicking
the save icon in the toolbar or clicking file->save menu,
IExecutionListener was not executed.

I read your articles but I still can't find how to fire the codes when i
click save icon in the toolbar or if i click file->save menu.

I also used IHandlerService.activateHandler but still same effect. It
works only when i pressed ctrl+s but won't work if i press the save in
toolbar on on file->save menu.

I tried the codes below

<extension point="org.eclipse.ui.handlers">
<handler commandId="org.eclipse.ui.file.save"
class="org.ui.handler.SaveHandler">
<enabledWhen>
<with variable="activePartId">
<equals
value=" org.eclipse.wst.xml.ui.internal.tabletree.XMLMultiPageEditor Part " />
</with>
</enabledWhen>
<activeWhen>
<with variable="activePartId">
<equals
value=" org.eclipse.wst.xml.ui.internal.tabletree.XMLMultiPageEditor Part " />
</with>
</activeWhen>
</handler>
</extension>

But still SaveHandler will only be execute in Ctrl+S. Clicking save icon
or file->save won't execute my code.

I didn't see in the ActionFactory that SAVE was hooked up to a command
like the other actions (in 3.4); might this explain Allan's
difficulties? And if that's the case, seems like a bug. I can help if
you want.

In 3.3 legacy actions (like SAVE) don't fire command execution events
.... only using the keybinding will.

In 3.4 we added extra legacy support so clicking the button should also
fire the same kind of events.

In 3.3 the other way around (in an RCP app, anyway) is to turn the
SaveAction into a handler and make Save in the menu and toolbar a
command contribution.
