[英]Linux / C++ Help with glade3 and gtkmm
Here is a C application source code, which creates GUI using Glade3 and GTK2+: 这是一个C应用程序源代码,它使用Glade3和GTK2 +创建GUI:
// gcc -o simple simple.c $(pkg-config --cflags --libs gtk+-2.0 gmodule-2.0)
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <gtk/gtk.h>
GtkBuilder *builder;
GtkWidget *window1;
G_MODULE_EXPORT void on_window1_destroy (GtkObject *object, gpointer user_data)
{
gtk_main_quit();
}
G_MODULE_EXPORT void on_button2_clicked (GtkObject *object, gpointer user_data)
{
gtk_main_quit();
}
G_MODULE_EXPORT void on_button1_clicked (GtkObject *object, gpointer user_data)
{
const gchar *name;
GtkWidget *name_entry = GTK_WIDGET(gtk_builder_get_object(builder, "entry1"));
name = gtk_entry_get_text(GTK_ENTRY(name_entry));
g_print("Name is: %s\n", name);
}
int main(int argc, char** argv)
{
GError *error = NULL;
/* Init GTK+ */
gtk_init( &argc, &argv );
/* Create new GtkBuilder object */
builder = gtk_builder_new();
/* Load UI from file. If error occurs, report it and quit application.*/
if( ! gtk_builder_add_from_file( builder, "simple.glade", &error ) )
{
g_warning( "%s", error->message );
g_free( error );
return( 1 );
}
/* Get main window pointer from UI */
window1 = GTK_WIDGET( gtk_builder_get_object( builder, "window1" ) );
/* Connect signals */
gtk_builder_connect_signals( builder, NULL );
/* Destroy builder, since we don't need it anymore */
//g_object_unref( G_OBJECT( builder ) );
/* Show window. All other widgets are automatically shown by GtkBuilder */
gtk_widget_show( window1 );
/* Start main loop */
gtk_main();
return( 0 );
}
and the glade file: 和林间文件:

Now I want to code this application in C++. 现在我想用C ++编写这个应用程序。 Can anyone give an example or tutorial using gtkmm? 任何人都可以使用gtkmm提供示例或教程吗? Or better convert this simple example for me? 或者更好地为我转换这个简单的例子? Thanks in advance! 提前致谢!
I suggest that you read the gtkmm tutorial . 我建议你阅读gtkmm教程 。
I can bother to convert it all but it would look something like this: 我可以费心去转换它,但它看起来像这样:
void button1_clicked()
{
...
}
int main(int argc, char argv)
{
Gtk::Main kit(argc, argv);
Glib::RefPtr<Gtk::Builder> builder = Gtk::Builder::create_from_file("my_gui.ui");
Gtk::Window *window1 = 0;
builder->get_widget("window1", window1);
Gtk::Button *button1 = 0;
builder->get_widget("button1", button1);
// get other widgets
...
button1->signal_clicked().connect(sigc::mem_fun(*this, &button1_clicked));
// connect more signals
...
Gtk::Main::run(*m_main_window);
return 0;
}
Note that you cannot use Glade to connect your signals when using gtkmm, you need to do that manually. 请注意,使用gtkmm时无法使用Glade连接信号,您需要手动执行此操作。
