Hi,
First, I want to apologize : I know such subjects have already been posted, but I still don't understand a thing

I have two windows in a Java/Cocoa project. Let's call the fist "mainWindow" and the second "sheetWindow". I would like the second one to appear as a sheet on the first as a button is clicked.

Can someone explain me how to do this in Java? The Apple's documentation is very poor on this subject.

Thanks a lot for your help,
A poor newbie in OS X programming

In Objective-C, I did it with the following:

[NSApp beginSheet:sheetWindow modalForWindow:mainWindow modalDelegate:self didEndSelector:@selector(sheetDone:returnCode:cont extInfo) contextInfo(void *)0];

Which causes you to need a delegate function like:
- (void)sheetDone NSWindow *)sheet returnCode int)returnCode contextInfo void *)contextInfo
{
}

Sorry that it's the wrong language. But I hope it helps anyways.

OK, here is the solution I found:

To make the sheet appear:
NSApplication.sharedApplication().beginSheet (sheetWindow,mainWindow,null,null,null);

To make it disappear:
NSApplication.sharedApplication().endSheet(sheetWi ndow);
sheetWindow.close();

Thanks for your help,
Thierry

I have a related question: How do I make windows with a little arrow in them that expands the window when you click on it? (Like, for instance, the copy dialog in the Finder.) This seems to be a standard way to hide more advanced or detailed information.

If this isn't a Cocoa thing, then I'll try using a tab view or a pull-down sheet.
