Does anyone have a good snippet of example code for calling NSOpenPanel
with CamelBones?

I am not certain what the syntax should be and there are few examples I
can find.

Thanks!

It figures that I have to post here to find where the examples are kept.

"Never mind!"

Did you check Apple's Cocoa Documentation?
Since CamelBones just wraps around the Objective-C functions, you can
use the documentation for that.

For starters, you can do something like this:

> my $panel = NSOpenPanel->openPanel;
> if ($panel->runModal) {
[quoted text clipped - 9 lines]
>
> }

There is also NSSavePanel to save files (rather than open them).

If you want to filter for specific files types you can do:

> my $types = NSMutableArray->alloc->init;
> $types->addObject('pod');
[quoted text clipped - 4 lines]
>
> if ($panel->runModalForTypes($types)) {

Hope it helps,

Thilo

Sometimes that works, sometimes it does not. It seems that a lot of
trial and error is involved.

BTW, this example is much more to the point than those in the example
programs. Much more commented as well. (The examples assume that you
are already proficient at Cocoa and Objective-C.)

How do I get the open and/or save dialog to open at a specific
directory? What I have tried has not worked.

That is pretty straightforward (it is explained in the Cocoa API
documents for Objective C )

Shameless plug:

You can try out this kind of code very quickly using PerlPad.
http://perl-pad.sourceforge.net/

Just copy & paste the above lines into PerlPad and see your NSOpenPanel
in action.
Much faster than a full compile cycle in ProjectBuilder.
