如何显示文档窗口的标题没有图标？ [英] How to show a title of document window without icon?

问题描述

现在我将一个文件拖动到坞站中的应用程序图标，这个应用程序是基于文档。我发现在应用程序运行和主窗口打开后，在窗口标题的左侧没有小的图像。但是当我拖动一个文件到应用程序运行之前的停靠图标，并使用此方法运行应用程序，窗口标题左侧的一个小图像显示文件，就像xcode等
现在我想以显示小图像两种方式或不显示小图像两种方式，怎么办？我认为它可能是基于文档的窗口属性，但我不知道如何解决它？谢谢！

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 etc. 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!

我使用 [mainWindow setTitle：tmp]; ，但图标仍然出现。当我使用 setTitleWithRepresentedFilename：我发现图标和窗口标题名都是修改，在文档类中重载 - （void）displayName;

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.
