A gtk interface for Go that feels right

go-gtk_vs_gg.go

//go-gtk
func on_window_resize(){
  window := gtk.WidgetFromObject(builder.GetObject("main_window"))
  switcher := gtk.WidgetFromObject(builder.GetObject("main_switcher"))
  vline := gtk.WidgetFromObject(builder.GetObject("vline"))

  win_alloc := new(gtk.GtkAllocation)
  window.GetAllocation(win_alloc)
  sw_alloc := new(gtk.GtkAllocation)
  switcher.GetAllocation(sw_alloc)

  if sw_alloc.Width != win_alloc.Width - 74 || sw_alloc.Height != win_alloc.Height {
    vline.SetSizeRequest(2,win_alloc.Height)
    switcher.SetSizeRequest(win_alloc.Width - 74, win_alloc.Height)
    Debug.Println("Resized switcher")
  }
}

//gg (Planned)
func onMainWindowResize(resize gg.Size){
	MainInterface.GetNotebook("main_switcher").SetSize(resize.Width - 74, resize.Height)
	MainInterface.GetVLine("vline").SetSize(2, resize.Height)
}

//OR maybe

window := gg.NewWindow()
window.OnResize = func(window gg.Window, resize gg.Size){
       window.GetNotebook("main_switcher").SetSize(resize.Width - 74, resize.Height)
       window.GetVLine("vline").SetSize(2, resize.Height)
}
