How show sheet loaded from xib? (MacOSx)
I have a xib file with only an NSPanel 开发者_开发技巧in it, I'm trying to show this panel as modal sheet (with beginSheet:modalForWindow:modalDelegate:didEndSelector:contextInfo:
). The file's owner for this xib is a controller class "MyController" which has the IBOutlet to the NSPanel.
What I am looking for is something like:
...
MyController *controller = [[MyController alloc] init];
[NSApp beginSheet:controller.panel modalForWindow:[NSApp mainWindow] modalDelegate:controller didEndSelector:nil contextInfo:nil];
...
Question:
Must MyController inherit from NSWindowController
or NSObject
?. I tried NSWindowController
and initWithWindowNibName:
but the outlet to NSPanel
always is nil.
Thanks
I resolve it. You must deactivate almost all the properties of the window object (in the IB) that you are using for the sheet. I add the following method to my controller to show the sheet:
- (void)showInWindow:(NSWindow *)mainWindow {
if (!panelSheet)
[NSBundle loadNibNamed:@"XibName" owner:self];
[NSApp beginSheet:panelSheet modalForWindow:mainWindow modalDelegate:nil didEndSelector:nil contextInfo:nil];
[NSApp runModalForWindow:panelSheet]; //This call blocks the execution until [NSApp stopModal] is called
[NSApp endSheet:panelSheet];
[panelSheet orderOut:self];
}
panelSheet
is an IBOutlet to the sheet window.
Thanks Jon Hess and JWWalker for your help
