Opening Java Editor from Double Click [message #53556]

Hi, I have created a new view with a list of java classes that have errors
specific
to my plugin (not the Task View!) - I want to be able to double click on an
item
in my table list and it will open the relevant class in a Java editor. At
the moment
I double click and it brings up the Sample view of saying "double click
detected",
but thats about it!

Also on an aside - how can I underline text like the java editor does with
a red or green line underneath specific text?

Regards,

Matt Hawkins

See the org.eclipse.ui.actions.OpenFileAction and ResourceNavigator.handleOpen for an example of how to use it.

The Java editor draws the squiggly lines on top of the text widget. It uses the AnnotationPainter to render annotations (search
results, errors). See also PaintManager and IPainter. You should be able to use an annotation painter.
Perhaps someone else can give a brief overview of how annotations work?

I've looked but I still do not understand what ResourceNavigator.handleOpen
does - it basically gets an ActionGroup (ResourceNavigator) and then
runs the defaultAction - which in ResourceNavigatorActionGroup is absolutely
nothing - and as for OpenFileAction that is completely wierd!

If anyone has some example code that they have specifically written for
their own view can they please give me a shout? Or alternatively if this
has been documented somewhere I would greatly appreciate a link :-)

defaultAction is first invoked on MainActionGroup from ResourceNavigator.handleOpen.
It ends up in OpenActionGroup.runDefaultAction which passes the current selection (your IFile that has errors) to the
OpenFileAction.
Look at the super and subclasses.
