Gtk::Dialog

Gtk::Dialog有以下几种：
Gtk::Dialog
Gtk::AboutDialog
Gtk::MessageDialog
Gtk::FileChooserDialog
Gtk::FontSelectionDialog
Gtk::ColorSelectionDialog

1. Gtk::Dialog只是原型可以使用get_vbox得到其中的Gtk::VBox layout.
及使用add_button(Gtk::Stock::OK, Gtk::RESPONSE_OK)这种形式加入按钮。

int result = dialog.run();
switch(result)
{
    case(Gtk::RESPONSE_OK)
    {
            //do something

    }
    case(Gtk::RESPONSE_XXX)
    {
            //do something

    }
    default:
    {
            //default

    }
}

2. Gtk::AboutDialog


Gtk::AboutDialog dialog();
dialog.set_transient_for(*this)

m_Dialog.set_name("Example application");
m_Dialog.set_version("1.0.0");
m_Dialog.set_copyright("Murray Cumming");
m_Dialog.set_comments("This is just an example application.");
m_Dialog.set_license("LGPL");

m_Dialog.set_website("");
m_Dialog.set_website_label("gtkmm website");

std::list<Glib::ustring> list_authors;
list_authors.push_back("Murray Cumming");
list_authors.push_back("Somebody Else");
list_authors.push_back("AN Other");
m_Dialog.set_authors(list_authors);

3. Gtk::MessageDialog

Gtk::MessageDialog dialog(*this, "This is a QUESTION MessageDialog",
          false /* use_markup */, Gtk::MESSAGE_QUESTION,
          Gtk::BUTTONS_OK_CANCEL);

dialog.set_secondary_text(
          "And this is the secondary text that explains things.");

int result = dialog.run();



4. Gtk::FileChooserDialog

  Gtk::FileChooserDialog dialog("Please choose a folder",
          Gtk::FILE_CHOOSER_ACTION_SELECT_FOLDER);
  dialog.set_transient_for(*this);

  //Add response buttons the the dialog:

  dialog.add_button(Gtk::Stock::CANCEL, Gtk::RESPONSE_CANCEL);
  dialog.add_button("Select", Gtk::RESPONSE_OK);

  int result = dialog.run();
//=============================


  Gtk::FileChooserDialog dialog("Please choose a file",
          Gtk::FILE_CHOOSER_ACTION_OPEN);
  dialog.set_transient_for(*this);

  //Add response buttons the the dialog:

  dialog.add_button(Gtk::Stock::CANCEL, Gtk::RESPONSE_CANCEL);
  dialog.add_button(Gtk::Stock::OPEN, Gtk::RESPONSE_OK);

  //Add filters, so that only certain file types can be selected:


  Gtk::FileFilter filter_text;
  filter_text.set_name("Text files");
  filter_text.add_mime_type("text/plain");
  dialog.add_filter(filter_text);

  Gtk::FileFilter filter_cpp;
  filter_cpp.set_name("C/C++ files");
  filter_cpp.add_mime_type("text/x-c");
  filter_cpp.add_mime_type("text/x-c++");
  filter_cpp.add_mime_type("text/x-c-header");
  dialog.add_filter(filter_cpp);

  Gtk::FileFilter filter_any;
  filter_any.set_name("Any files");
  filter_any.add_pattern("*");
  dialog.add_filter(filter_any);

  //Show the dialog and wait for a user response:

  int result = dialog.run();


5. Gtk::FontSelectionDialog

Gtk::FontSelectionButton m_button;
m_button.signal_on_font_set(sigc::mem_fun(*this, &on_button_font));

void on_button_font(){
  Glib::ustring font_name = m_Button.get_font_name();
}

6. Gtk::ColorSelectionDialog

Gtk::ColorSelectionButton m_button;
m_button.signal_on_color_set(sigc::mem_fun(*this, &on_button_font));

void on_button_font(){
  Glib::ustring font_name = m_Button.get_color();
  m_DrawingArea.modify_bg(Gtk::STATE_NORMAL, m_Color)
}
