[SlowLogicBoy]

Expected Behavior

Expander.Header.Focus() triggered.

Actual Behavior

Expander.Header.Focus() not triggered.

Steps to Reproduce the Problem

1. Run Code Below

Code that Demonstrates the Problem

#! "netcoreapp2.0"
#r "nuget: Eto.Platform.Gtk, *"

using Eto.Drawing;
using Eto.Forms;

var app = new Application(new Eto.GtkSharp.Platform());
var expander = new Expander {
    Header = new TextBox(),
    Content = "Woot?"
};
app.Run(new Form {
    Content = expander
});

Workaround

expander.MouseUp += (s, ee) => {
    if(expander.Header.Bounds.Contains(new Point(ee.Location)))
    {
        expander.Header.Focus();
        ee.Handled = true;
    }
};

Thanks for reporting the issue! Not sure if that is actually supported by Gtk, but it's worth checking into.

Can you tab to the control with the keyboard? If so it might just be the click event that needs overriding.

I think the problem here is the fact that Eto does not provide a SetExpanded(bool) function, which btw. is totally possible with Gtk: https://developer.gnome.org/gtk3/stable/GtkExpander.html#gtk-expander-set-expanded

Oh wait, I misunderstood the issue..
