Invoking Find/Replace [message #333890]

Hi all,

I'm trying to create a simple Find/Replace dialog by reusing the standard
Ctrl+F dialog. I have a SourceViewer and I'm catching the Ctrl+F now. I
call doFindReplace(), below. I've tried to create an action, like this:
protected void doFindReplace() {
ActionFactory.FIND.create( getActiveWorkbenchWindow());
FindReplaceAction fandrAction = new FindReplaceAction(getPRB(),
"Editor.FindReplace.", getActiveWorkbenchPart());

fandrAction.runWithEvent(new Event());
// fandrAction.run();

}

None of that code works - nothing ever pops up. What am I doing wrong?
FWIW, getPRB() returns an empty resource bundle. Do I need to instantiate
the FindReplaceDialog class myself? Do I need to subclass
FindReplaceAction, overriding run() myself? I just want a simple
find/replace dialog to pop up, targeted at my editor (from which I pressed
Ctrl+F).

I cannot find any examples, though. I'm targeting v3.2 in case the API
has changed in the last year or so.

Thanks in advance!

Bret

Make sure your active workbench part provides an IFindReplaceTarget adapter.

Thanks for the reply, Dani. I'm confused, though, since my SourceViewer
is a TextViewer, which appears to have all the right methods required of a
IFindReplaceTarget, although it doesn't say it implements that interface
on this page:
http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse. platform.doc.isv/reference/extension-points/index.html

If I try to implement IFindReplaceTarget in my subclassed SourceViewer I
get a message that TextViewer.findAndSelect(...) cannot hide the public
abstract method in IFindReplaceTarget. I can do this:
fSourceViewer.getFindReplaceTarget(), but I cannot pass that to the
FindReplaceAction constructor, which wants a WorkbenchPart, not a
FindReplaceTarget.

Ideas?

Thanks again,

Bret

Dani,

Were you suggesting this?

FindReplaceAction fandrAction = new FindReplaceAction(getPRB(), null,
(IWorkbenchPart)
getActiveWorkbenchPart().getAdapter(IFindReplaceTarget.class .getClass()));

I tried that and I still don't get a popup.

I found out the ActiveWorkbenchPart() is returning a tab at the bottom of
my IDE called "Properties". My Editor is *inside* the body of that tab.
My editor extends a SourceViewer, which would have an IFindReplaceTarget
(because SourceViewer extends a TextEditor).

I'm open to suggestions if you have a minute.

Thanks!

Bret

SourceViewer does not extend TextEditor.

Either the part from getActiveWorkbenchPart() must return a valid
IFindReplaceTarget (which the Properties view probably won't) or you
must use the 3.3 API:
FindReplaceAction.FindReplaceAction(ResourceBundle, String, Shell,
IFindReplaceTarget) where you pass in
yourTextViewer.getFindReplaceDocumentAdapter().

My mistake - I thought it did. Thanks.

Hmmmm... I added both the v3.3 and the v3.4
org.eclipse.ui.workbench.texteditor.jar to my Eclipse project and I get no
complaints from Eclipse when I use that constructor, but they both cause
problems further down the line when I try to start my app due to their
upgraded version requirements (i.e. they want upgraded jface and other
jars).

Thanks for your assistance, Dani, but it looks like I'm stuck :-(. I
wonder if I can reimplement my editor to implement the IFindReplaceTarget
interface...

Rgds,

Bret

Sure. You can't just go and grab a single JAR from one version and put
it into the other one.
