Question

我正在使用GTK + 3.0库使用C GUI。我正在使用工具Glade我想知道在Glade中制作GUI之后实际上＆＃34; c＆＃34;文件为该GUI生成。

Answer 1

Glade-3不会生成可以编译的.c文件。它生成一个.glade（.ui），它是一个XML文件，用于描述小部件的布局和要连接的信号。您在运行时将此文件加载到程序中以创建窗口小部件。很老的版本确实生成了.c文件但是很久以前。

在应用程序中使用Glade文件需要使用的大多数函数都基于GtkBuilder和以gtk_builder _ *（）开头的函数。 API文档位于https://developer.gnome.org/gtk3/stable/GtkBuilder.html。

示例test.c程序： -

#include <gtk/gtk.h>

#define UI_FILE "test.ui"
#define WIDGET_WINDOW "a_window"

/* Callback for the buttons */
void on_button_clicked (GtkButton* button,
                        gpointer user_data)
{
  gtk_main_quit();
}

int main(int argc, char *argv[])
{
  GtkWidget *window;
  GtkBuilder *builder;

  /* Initialize gtk+*/
  gtk_init (&argc, &argv);

  builder = gtk_builder_new ();
  gtk_builder_add_from_file (builder, UI_FILE, NULL);

  window = GTK_WIDGET (gtk_builder_get_object (builder, WIDGET_WINDOW));
  gtk_builder_connect_signals (builder, NULL);

  gtk_widget_show (window);

  gtk_main ();
  return 0;
}

其对应的Glade文件test.ui
