gtk_statusbar question

[Vasiliy G Tolstov <v tolstov selfip ru>]

Hello.
I'm try to use gtk_statusbar in my application.
I'm use gtkbuild to load GtkWidget.
Then i'm click to open file executes on_open_menu_item_activate,
Widgets struct contains all needed widgets, but message not displayed in
statusbar, only errors in colsole, where is my mistake?
Please help me..
