Re: Multiple nibs in PB/IB?

Thanks, I think this makes some sense. A couple of more questions
if I may. What is retain()? I can't seem to find it in any of the docs I
have.

Also, are there any examples for this sort of thing? The cocoa-java
documentation seems to be rather lacking.

Finally, it seems that it's the case that if I wanted a single controller
in my application I would subclass inside of IB, but not generate
a file. This would let me wire things from one nib to another e.g.

public class MyMainController{
// Stuff
public void loadTheNibThingee(Object sender) { /* IBAction */
NSApplication.loadNibNamed("MyNibFile", this);
}

and the other nib would have a definition of my class and that's
all. Does this make sense.

Oh, and really finally, is there a penalty for calling loadNibNamed
multiple times with the same argument or is the nib data cached?

Many thanks for your assistance.

You can definitely have more than one NIB in Cocoa/Java programs.
I use many, but I never asked IB to parse existing Java files - only subclassed java.lang.Object
and made the file's owner that class.

I then load the extra NIBS by
{
CashbookViewer editor = new CashbookViewer();
this.retain(editor);
NSApplication.loadNibNamed("CashbookNIB", editor); }
where CashbookViewer would be the class (fully qualified) of File's Owner in NIB file.

As an aside, I find that, in the example above, if editor gets Java garbage collected
then a program crash occurs. I am still not sure what the best way around this problem is,
so I just keep a handle to editor around....

What do people do in situations when they are frequently creating/destroying stuff?
For instance, if I close the window in the CashbookNIB its gone and all released on Cocoa
side, but I still have the editor object referenced in my Java program.

Cheers,
Steve

Hello. I'm trying to do something that I thought was simple but may not be. Basically
I'm trying to create another nib inside of my project. (Just to be clear, this is a
cocoa-java application). What I'm doing specifically is following an example
for creating an about box in the book "Building Cocoa Applications" which is
an ObjC book.

Anyway, what I do is create a nib directly in IB choosing the empty cocoa
thing. I want the "File's Owner" in the instances panel to be a specific Java
class so that I can wire it up using the control drag stuff. What I'm finding is
that IB won't parse Java files. At least I can't figure out how to do that.

So this leads me to 2 questions:

1 - Can you have more than 1 nib in a Cocoa-Java appl built with PB/IB?

2 - Can you import a Java class into IB when you create the nib from within
IB (and not PB)?

Kinda frustrated,
