GTK 2 的 gdk_x11_drawable_get_xid 方法,而不是 GtkSharp 3.24 对应的 GTK 3 的方法 以上的 gdk_x11_drawable_get_xid 方法需要构建传入 /en.wikipedia.org/wiki/GDK 从 Gtk 的 Window 窗口获取 Gdk 的 Window 窗口,可使用以下简单代码获取 Gtk.Window window = xxx; Gdk.Window gdkWindow = window.Window; 获取 Gdk 窗口指针,可通过 Handle 属性获取,如以下代码 Gdk.Window _window_get_xid 方法即可正确的从 gdk 窗口获取到对应的 X11 窗口的 XID 值 为了方便使用 gdk_x11_window_get_xid 方法,以下照 GtkSharp 进行一些代码定义 <d_gdk_x11_window_get_xid>("libgdk-3.so.0", "gdk_x11_window_get_xid"); private static T LoadFunction

这时候有两种方法可以帮你: 1.修改启动脚本调整export GDK_SCALE=2 # 缩放应用大小 2.打开DESK或者DBCS软件,在软件界面左下方进行微调 下面我们对两种方法进行简单介绍。 这种方法效果非常明显,但是GDK_SCALE变量只接受整数。
