如何检索gtk窗口的窗口ID [英] How can i retrieve Window ID of gtk window

问题描述

我有一个需要使用XV显示流式视频的应用程序.

I am having an application where i need to display streaming video using XV.

我将顶级窗口ID传递给底层的视频播放应用程序，该应用程序会将子窗口(其中包含流式视频的子窗口)附加/添加到我的窗口中.因此，我需要获取操作系统提供的顶级窗口的ID.

I will pass top-level window ID to underlying video playing application which will Attach/Add child window (child window with streaming videos in it) to my window. So for that I need to get ID of top level window provided by operating system.

我正在Linux上使用GTK +和C.

I am using GTK+ and C on Linux.

推荐答案

您使用

You use the GDK_DRAWABLE_XID() macro, assuming you're on X11:

GtkWindow *mywindow;
GdkWindow *gwin;

gwin = gtk_widget_get_window(GTK_WIDGET(mywindow));
printf("the X11 id is %u\n", GDK_DRAWABLE_XID(gwin));
