glade3教程（五）--对话框
打开glade放置一个窗口，然后在窗口上放置一个按钮 然后放置一个信息对话框在对话框上面放置两个按钮保存为dialog.glade如图所示http://www.bailangcn.tk/content/uploadfile/201203/thum-8266e4bfeda1bd42d8f9794eb4ea0a1320120321153651.pnghttp://www.bailangcn.tk/content/uploadfile/201203/thum-2fc30b834379e7cde1af4a5107a50fe920120321153713.pnghttp://www.bailangcn.tk/content/uploadfile/201308/dialog1.png http://www.bailangcn.tk/content/uploadfile/201308/dialog2.png
打开code::blocks 输入以下代码代码都比较简单/*作者：bailangcn时间：2012/3/21作者主页：bailangcn.tk*/#include <gtk/gtk.h>void show_dialog(void)
{
GtkWidget *dialog;
GtkWidget *builder;
GtkResponseType response;
builder = gtk_builder_new();
gtk_builder_add_from_file(builder, "dialog.glade", NULL);
dialog = GTK_WIDGET(gtk_builder_get_object(builder,"messagedialog"));
response = gtk_dialog_run (GTK_DIALOG (dialog));
if(response==GTK_RESPONSE_OK)
{
g_printf("ok\n");
}
else if(response==GTK_RESPONSE_CANCEL)
{
g_printf("CANCEL\n");
}
gtk_widget_destroy(GTK_WIDGET(dialog));
g_object_unref(G_OBJECT(builder));
}int main(int argc, char *argv[])
{
GtkBuilder *builder; gtk_init(&argc, &argv);
GtkWidget *window; GtkWidget *button1;
builder = gtk_builder_new();
gtk_builder_add_from_file(builder, "dialog.glade", NULL); window = GTK_WIDGET(gtk_builder_get_object(builder, "window"));
button1 = GTK_WIDGET(gtk_builder_get_object(builder,"button1"));
g_signal_connect(G_OBJECT(window),"delete_event",G_CALLBACK(gtk_main_quit),NULL);
g_signal_connect(G_OBJECT(button1),"pressed",G_CALLBACK(show_dialog),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)); gtk_widget_show_all(window);
gtk_main();
return 0;
}运行后如下：http://www.bailangcn.tk/content/uploadfile/201203/thum-85920d0ea71eaeaaaa14b4f8b903c8e220120321154110.png
解释一下：在gtkdialog.h里面有这样子的定义typedef enum
{
/* GTK returns this if a response widget has no response_id,
* or if the dialog gets programmatically hidden or destroyed.
*/
GTK_RESPONSE_NONE = -1,/* GTK won't return these unless you pass them in
* as the response for an action widget. They are
* for your convenience.
*/
GTK_RESPONSE_REJECT = -2,
GTK_RESPONSE_ACCEPT = -3,/* If the dialog is deleted. */
GTK_RESPONSE_DELETE_EVENT = -4,/* These are returned from GTK dialogs, and you can also use them
* yourself if you like.
*/
GTK_RESPONSE_OK = -5,
GTK_RESPONSE_CANCEL = -6,
GTK_RESPONSE_CLOSE= -7,
GTK_RESPONSE_YES = -8,
GTK_RESPONSE_NO = -9,
GTK_RESPONSE_APPLY= -10,
GTK_RESPONSE_HELP = -11
} GtkResponseType;
本文始发于：http://www.bailangcn.tk/?post=20转载请注明 本来我是一次性将控件从glade文件里面提取出来 ，然后运行的时候再显示，用完再隐藏起来，经测试发现第一次运行很正常，但是隐藏之后再显示出来就有些显示不出来了，不知道是什么原因，最后去国外的英文社区去看，发现蛮多人也是这样子的，有大神说在显示控件函数中再提取就好了，经测试发现的确是正常的，这样子做有什么不良的后果吗？有知道的人请赐教
