This is a newbie question I am certain. I am experimenting with sheets with
a simple application (1st cocoa app) and want to display a simple alert
message as a sheet.
1) So my first mistake was to use NSRunAlertPanel(). Did its thing but gave
me an independent window.
2) Further reading disclosed NSBeginAlertSheet(). Again an independent
window! Here is my code fragment:
...
//NSRunAlertPanel( @"TITLE", @"MESSAGE", @"BUTTON1", @"BUTTON2",
@"BUTTON OTHER") ;
NSBeginAlertSheet(@"TITLE", @"DFLT BUTTON", @"ALT BUTTON", @"OTHER
BUTTON",
[sourceTableView window],
self, // modal delegate
@selector(sheetDidEnd:returnCode:contextInfo:),
nil, // didDismissSelector
nil, // contextInfo
@"MESSAGE") ;
...
3) I then tried to create an NSPanel and use NSApp::beginSheet: do get the
job done. Again an independent window
...
// create a new panel
NSPanel* sheet = [[NSPanel new] init] ;
// now run the panel/sheet
[NSApp beginSheet:sheet
modalForWindow: [sourceTableView window]
modalDelegate: nil
didEndSelector: nil
contextInfo: nil] ;
[NSApp runModalForWindow:[sourceTableView window]] ;
[NSApp endSheet:[sourceTableView window]];
[[sourceTableView window] orderOut:self] ;
...
I guess I would have expected that #2 or #3 would have resulted in a sheet
on my main application window. What obvious detail did I miss?
TIA,
