密码错误:名称“ set_revealed”在“ Gtk.InfoBar”的上下文中不存在

标签: gtk3 vala

我在自己的用户界面中添加了一个Gtk.InfoBar,一切看起来都很好。在Glade中,我可以将信息栏切换为“已显示”,反之亦然。

valadoc.org文档set_revealed上列出了允许的方法。

  

公共无效set_revealed(已显示布尔)

     

将GtkInfoBar:revealed属性设置为显示。

但是在构建项目时,我会复习error: The name 'set_revealed' does not exist in the context of'Gtk.InfoBar'

我在做什么错了?

这是我的代码:

namespace Zeiterfassunggtk {
    [GtkTemplate (ui = "/org/gnome/Zeiterfassunggtk/window.ui")]
    public class Window : Gtk.ApplicationWindow {
        [GtkChild]
        Gtk.TreeView treeview1 = new Gtk.TreeView ();
        [GtkChild]
        Gtk.Button refreshbutton;
        [GtkChild]
        Gtk.MenuButton menubutton;
        [GtkChild]
        Gtk.Button menubuttonrefresh;
        [GtkChild]
        Gtk.Button menubuttonsave;
        [GtkChild]
        Gtk.Button menubuttonquit;
        [GtkChild]
        Gtk.InfoBar infobar1;
        [GtkChild]
        Gtk.Label infobar1label;

        Gtk.TreeIter iter;
        Gtk.ListStore liststore1 = new Gtk.ListStore (3, typeof (string), typeof (string), typeof (string));

        private void setup_treeview (Gtk.TreeView treeview1) {
            treeview1.set_model (liststore1);

            treeview1.insert_column_with_attributes (-1, "Name", new Gtk.CellRendererText (), "text", 0, null);
            treeview1.insert_column_with_attributes (-1, "Job", new Gtk.CellRendererText (), "text", 1, null);
            treeview1.insert_column_with_attributes (-1, "Time", new Gtk.CellRendererText (), "text", 2, null);

            liststore1.append (out iter);
            liststore1.set (iter, 0, "Gerald", 1, "Job1", 2, "2018-01-01 18:23", -1);
        }

        void refresh () {
            liststore1.append (out iter);
            liststore1.set (iter, 0, "Gerald", 1, "Job1", 2, "2018-01-01 18:23", -1);
            //infobar1.set_revealed (true);
        }

        void save () {
            liststore1.append (out iter);
            liststore1.set (iter, 0, "Gerald", 1, "Job2", 2, "2018-01-01 24:00", -1);
        }

        public Window (Gtk.Application app) {
            Object (application: app);

            this.maximize ();

            this.setup_treeview (treeview1);

            infobar1.set_revealed (false);

            refreshbutton.clicked.connect (this.refresh);
            menubuttonrefresh.clicked.connect (this.refresh);
            menubuttonsave.clicked.connect (this.save);

            menubuttonquit.clicked.connect (app.quit);

            this.show_all ();
        }
    }
}

似乎您正在导入旧版的Gtk +。您的window.ui状态为<requires lib="gtk+" version="3.16"/>

set_revealed可从[ Version ( since = "3.22.29" ) ]获得。

您似乎必须进行更新。
