C / GTK转换结构的GtkWindow的类型 [英] c/gtk convert structure to the type of GtkWindow

问题描述

我有以下结构，

    typedef struct _MainWin
    {
        GtkWindow parent;
        GtkWidget* scroll;
        GtkWidget* box;
    }MainWin;

我创建了从这种结构的应用程序主窗口。现在我需要在全屏幕的主窗口。当我试图打电话，

I have created the application main window from this structure. Now I need the main window in full screen. When I tried to call,

gtk_window_fullscree(GTK_WINDOW(mw);

其中， MW 是 MainWin能够的对象。我得到了以下错误消息 gtk_window_fullscreen：断言 GTK_IS_WINDOW（窗口）failed`

Where mw is object of MainWin. I got the following error message gtk_window_fullscreen: assertionGTK_IS_WINDOW (window)' failed`

我怎么能带领 MW 到的GtkWindow ？

感谢您。

推荐答案

这似乎是错误的。您的GtkWindow应该是一个指针过了，通过创建的 gtk_window_new（） 像任何其他的GTK +部件。这看起来像你想继承了的GtkWindow结构，我不认为你可以做到这样。

This seems wrong. Your GtkWindow should be a pointer too, and created using gtk_window_new() like any other GTK+ widget. This looks like you're trying to "subclass" the GtkWindow struct, which I don't think you can do like this.
