How to show a title of document window without icon?

Question

Now I drag a file to the app icon in the dock, this app is based on document . I found that no little image on the left of window title after the app is run and the mainwindow is open . but when I drag a file to the dock icon before the app run and use this method to run the app , a little image on the left of window title to show the file ,just like the xcode ect. Now I want to show the little image both way or not to show the little image both way , How to do ? I think that it maybe the window property based on document , but I don't know how to fix it ? Thanks!

Answer 1

From the cococa docs for NSWindow (under representedURL):

[[window standardWindowButton:NSWindowDocumentIconButton] setImage:image]

Maybe setting it to nil will do the trick?

Answer 2

If you just use -setTitle:, no icon. If you use -setTitleWithRepresentedFilename: you get the icon.

Answer 3

I used the [mainWindow setTitle:tmp];,but icon still appear.when I used setTitleWithRepresentedFilename: I found that both icon and window title name both are modify,in the document class I overload the -(void)displayName;so I want to the window title is fixed anytime.

Answer 4

Ok , I find the result: 1.[[window standardWindowButton:NSWindowDocumentIconButton] setImage:image] 2.- (BOOL)window:(NSWindow *)sender shouldPopUpDocumentPathMenu:(NSMenu *)titleMenu { return NO; }
