GTK/Development

Write a simple message dialog app

You can write your own GTK 3 message dialog easily in many programming languages through GObject-Introspection or bindings, or you can simply use bash.

The following examples display a simple "Hello world" in a message dialog.

Ada

Makedependency: gcc-ada
Build with: gnatmake hello_world `gtkada-config`

hello_world.adb

with Gtk.Main;
with Gtk.Dialog;           use Gtk.Dialog;
with Gtk.Message_Dialog;   use Gtk.Message_Dialog;

procedure hello_world is
  Dialog   : Gtk_Message_Dialog;
  Response : Gtk_Response_Type;
begin
  Gtk.Main.Init;
  Gtk_New (Dialog   => Dialog,
           Parent   => null,
           Flags    => 0,
           The_Type => Message_Info,
           Buttons  => Buttons_OK,
           Message  => "Hello world!");
  Format_Secondary_Markup (Dialog, "This is an example dialog.");
  Response := Run (Dialog);
end hello_world;
