Content Assist, Focus within the brackets, JFace [message #493125]

Hi there,

I want to implement some basic comfort functions to my JFace editor.
For example:
The user types System.out. and selectes println(boolean b) in the content assist. The java editor in eclipse selects the variable b automatically, so that the user can type the needed parameter within the brackets.

Another example:
If the user selects a method via content assist - lets use system.out.println(b) again - and types ")"within the brackets, the typed closing bracket is considered as closing bracket of the function. As a result, the cursor is located behind the closing bracket.

How are those features provided?
Is there a possibility to see the whole Java Editor source code?

I would be very appreciative, if someone can give me any hints about my topic

Best regards
StefanK

Maybe this question is the most important:

Where can I download the complete Eclipse Java Editor plugin?
I found editor examples at:

http:// dev.eclipse.org/viewcvs/index.cgi/org.eclipse.ui.examples.ja vaeditor/

Best regards

It's part of the Eclipse Platform Examples. See
<http://www.eclipse.org/swt/examples.php#insideEclipse> for how to
download and install.

Hello Brian,
thanks for your reply. Unfortunately, the java editor example is exactly the same as the example from the repository.

I downloaded the whole java editor from the repository, you can find it under org.eclipse.jdt.ui..

Does anyone have experience with the editor? Where can I post my questions about it?

This is implemented using LinkedModeModel and LinkedModeUI (or something
named like that, 'Open Type' can help you figure out its exact names).

I don't know about the other feature though.

Ah, sorry.

I'd try the JDT newsgroup: eclipse.tools.jdt.

The feature you're trying to implement is called content assist in
Eclipse. There looks to be some JFace support in
org.eclipse.jface.text.contentassist. I vaguely recall seeing some
articles about adding content-assist support.
