Connecting event to calendar

[rossati]

Hi
I am new on Julia and
I am trying to use the GTK Calendar:

using GTK3_jll 
const libgtk = libgtk3
using Gtk, Gtk.ShortNames
function fnz(x)
    println("$x")
end
win = GtkWindow( "Try Calendar")
c = ccall((:gtk_calendar_new,libgtk), Ptr{GObject}, (Ptr{UInt8},),"")
push!(win,c)
z = showall(win)
return ""

The problem arises when I try to link the day-selected signal to a Julia function:

First attempt

via g_signal_connect function

fnz_c = @cfunction(fnz,Cvoid,(Ref{String},))
ccall((:g_signal_connect,libgtk),Ptr{GObject},(Ptr{GObject},Ptr{GObject},Ptr{Cvoid}),c,"day-selected",fnz_c)

I obtain could not load symbol "g_signal_connect" and I not found where the function is declared.

Second attempt

via gtk.jl signal_connect function

id = signal_connect(fnz, c, "day-selected")

In this case the error is: no method matching signal_connect that I suppose for c is a ::Ptr{GObject} and the function needs ::GObject, but I not know how transform a ::Ptr{GObject} into a ::GObject.
Thanks for any sggestions

c = convert(GObject, ccall((:gtk_calendar_new,libgtk), Ptr{GObject}, (Ptr{UInt8},),""))

Or generate the widget with GtkBuilder.

Very thank TKnopp
So with GtkBuilder I can easy access to widget non covered by Gtk.jl?

[tknopp]

exectly. They will be considered to be GtkWidget and with that you can do already quite a lot.

I tried, it works very well with file created by Glade, but the GtkBulder by the same string of file doesn't works.
My be is an old problem because i seen an unanswered request on StackOwerflow.
