Question

我试图创建一个＆＃34; HeaderMenu＆＃34;像这样：

但只有我明白了：

我在GtkHeaderBar中使用GtkMenuButton。如何获得第一张照片的菜单？

代码：

Answer 1

从GTK + 3.12开始，将use-popover property of the GtkMenuButton设置为TRUE。

编辑哦，您实际上正在使用GtkMenu和GtkMenuButton的popup属性。为此，您需要切换到使用menu-model property而不是GtkMenu的GMenu。不，GtkMenu不是GMenu，因此您不能简单地更改glade文件中属性的名称。 GMenus在架构上与GtkMenus不同，所以你需要做一些重写。
