glade3教程（三）--单行文本框
废话少说， 当然是先打开glade3放置一个窗口在窗口上放置一个固定容器然后然后在容器上放置一个单行文本框 在文本框下面放置两个按钮 在按钮下面放置一个标签 保存为entryreset.glade名称之类的如图所示：http://www.bailangcn.tk/content/uploadfile/201203/thum-8266e4bfeda1bd42d8f9794eb4ea0a1320120315131457.png在code::blocks下输入以下代码：/*作者：bailangcn时间：2012/3/15作者主页：bailangcn.tk*/
#include <gtk/gtk.h>
GtkWidget *entry;
GtkWidget *label;
void get_entry_to_label(GtkWidget *Widget,gpointer data)
{
const gchar *text; text = (gchar *)malloc(sizeof(gchar));
text = gtk_entry_get_text(GTK_ENTRY(entry));//获取entry的内容 gtk_label_set_text(GTK_LABEL(label),text);//设置label的内容
}
void reset_entry(GtkWidget *Widget,gpointer data)
{
gtk_entry_set_text(GTK_ENTRY(entry),"欢迎光临www.bailangcn.tk");//设置entry的内容
}
int main(int argc, char *argv[])
{
GtkBuilder *builder; gtk_init(&argc, &argv);
GtkWidget *window; GtkWidget *button;
GtkWidget *reset; builder = gtk_builder_new();
gtk_builder_add_from_file(builder, "entryreset.glade", NULL); window = GTK_WIDGET(gtk_builder_get_object(builder, "window"));
entry = GTK_WIDGET(gtk_builder_get_object(builder,"entry"));
button = GTK_WIDGET(gtk_builder_get_object(builder,"button"));
reset = GTK_WIDGET(gtk_builder_get_object(builder,"reset"));
label = GTK_WIDGET(gtk_builder_get_object(builder,"label"));
g_signal_connect(G_OBJECT(window),"delete_event",G_CALLBACK(gtk_main_quit),NULL);
g_signal_connect(G_OBJECT(button),"pressed",G_CALLBACK(get_entry_to_label),NULL);
g_signal_connect(G_OBJECT(reset),"pressed",G_CALLBACK(reset_entry),NULL); // gtk_builder_connect_signals(builder, NULL);//自动关联已在 UI 文件配置好的信号如果你不在galde文件里面配置信号这行代码可以不用
g_object_unref(G_OBJECT(builder));//释放builder gtk_widget_show_all(window);
gtk_main();
return 0;
}编译运行可得如下界面：http://www.bailangcn.tk/content/uploadfile/201203/9efe1efa6f059a08f8257b76076b562a20120315132032.png输入文字按确定如下：http://www.bailangcn.tk/content/uploadfile/201203/91db2edef695d914308451eb36588d0e20120315132402.png按下重置如下：http://www.bailangcn.tk/content/uploadfile/201203/b0bc7a51281455991fb349c8ea1bed5520120315132417.png
