c - 如何使 gtk 代码工作？

Question

vbox = gtk_vbox_new(FALSE, 0);
gtk_container_add(GTK_CONTAINER(window), vbox);
...
frame = gtk_fixed_new();
gtk_container_add(GTK_CONTAINER(window), frame);
...

上面的代码将生成以下警告:

Gtk-WARNING **: Attempting to add a widget with type GtkFixed to a GtkWindow, but as a GtkBin subclass a GtkWindow can only contain one widget at a time; it already contains a widget of type GtkVBox

frame 中的结果未显示在窗口中。

如何让 vbox 和 frame 同时显示？

Answer 1

将它们放在周围的垂直盒子中(如果你想垂直堆叠它们):

parentVbox = gtk_vbox_new(FALSE, 0);

vbox = gtk_vbox_new(FALSE, 0);
gtk_box_pack_start(GTK_BOX(parentVbox), vbox, TRUE, TRUE, 0);
...
frame = gtk_fixed_new();
gtk_box_pack_start(GTK_BOX(parentVbox), frame, TRUE, 0);
...
gtk_container_add(GTK_CONTAINER(window), parentVbox);
