如何将工具栏按钮连接到另一个小部件的插槽？

Question

I'am trying some tutorials with Glade and GTKmm. For now I have a Main Window with a Toolbar. This is my Main Menu. Every Toolbarbutton should trigger the "show" and "hide" option of a widget. In this case I have a widget called Overview. So, how do I connect the Toolbarbutton signal to a function (Slot) of the overview widget?

Here is a little bit of code I already have.

只需连接一个信号：

tbtnOverview->signal_clicked().connect(wndOverview, &Overview::Method_To_Fire);
