Question

我正在尝试创建一个简单的程序，从glade文件中获取GtkHButtonBox，向其添加一个按钮并显示整个窗口。问题是我看不到任何添加的按钮，我没有看到任何警告错误或断言。

这是我的main.c文件：

#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#include <string.h>
#include <stdio.h>

#include <gtk/gtk.h>


GtkBuilder *builder;


#define UI_FILE "gtk_hbuttonbox.ui"


int
main (int argc, char *argv[])
{
GtkWidget *window,*box, *button;


gtk_set_locale ();
gtk_init (&argc, &argv);
GError* error = NULL;

builder = gtk_builder_new ();
if (!gtk_builder_add_from_file (builder, UI_FILE, &error))
{
    g_warning ("Couldn't load builder file: %s", error->message);
    g_error_free (error);
}

/* This is important */
window = GTK_WIDGET (gtk_builder_get_object (builder, "window"));
box = GTK_WIDGET (gtk_builder_get_object (builder, "hbuttonbox1"));

g_object_unref (builder);

button = GTK_WIDGET(gtk_button_new_with_label ("moshe"));

gtk_box_pack_start (GTK_BOX(box),button,FALSE,FALSE,0);

gtk_widget_show (button);
gtk_widget_show (window);

gtk_main ();
return 0;
}

这是我的gtk_hbuttonbox.ui glade文件：

<?xml version="1.0"?>
<interface>
  <requires lib="gtk+" version="2.16"/>
  <!-- interface-naming-policy project-wide -->
  <object class="GtkWindow" id="window">
    <property name="visible">True</property>
    <property name="title" translatable="yes">window</property>
    <property name="default_width">500</property>
    <property name="default_height">400</property>
    <signal name="destroy" handler="destroy" object="NULL"/>
    <child>
      <object class="GtkHButtonBox" id="hbuttonbox1">
        <property name="visible">True</property>
        <child>
          <placeholder/>
        </child>
        <child>
          <placeholder/>
        </child>
        <child>
          <placeholder/>
        </child>
      </object>
    </child>
  </object>
</interface>

使用gtk + 2.22.1和glade 3.6.7

如何解决问题？

感谢

Answer 1

也许只是缺少gtk_widget_show（按钮）？

Answer 2

而不是

gtk_widget_show (button);
gtk_widget_show (window);

使用：

gtk_widget_show_all (window);

这将显示主窗口及其所有子窗口小部件。

c gtk + -2：无法看到添加到GtkHButtonBox的按钮
