Class SSHMenu::MenuDialog
In: lib/sshmenu.rb  (Git)
Parent: Object

The SSHMenu::MenuDialog class implements the dialog for editing a SSHMenu::MenuItem. Once the MenuDialog object has been constructed, its invoke method is called to display the dialog. When the user dismisses the dialog, the invoke method will return nil on cancel or the edited menu item on OK.

# File lib/sshmenu.rb, line 2646
    def build_dialog
      dialog = Gtk::Dialog.new(
        "Submenu Name",
        nil,
        Gtk::Dialog::MODAL | Gtk::Dialog::DESTROY_WITH_PARENT,
        [Gtk::Stock::OK, Gtk::Dialog::RESPONSE_ACCEPT],
        [Gtk::Stock::CANCEL, Gtk::Dialog::RESPONSE_REJECT]
      )
      dialog.default_response = Gtk::Dialog::RESPONSE_ACCEPT
      dialog.window_position = Gtk::Window::POS_MOUSE

      @body = Gtk::VBox.new(false, 0)
      @body.set_border_width(4)
      dialog.vbox.add(@body)

      label = Gtk::Label.new('Title')
      label.set_alignment(0, 1)
      @body.pack_start(label, false, true, 0)

      widget = Gtk::Entry.new
      widget.width_chars       = 36
      widget.text              = @menu.title
      widget.activates_default = true

      @title_entry = widget

      @body.pack_start(widget, false, true, 0)

      dialog.show_all

      return dialog
    end
inputs_valid?()

Validation routine - blocks saving if the title input is empty.

[Source]

# File lib/sshmenu.rb, line 2635
    def inputs_valid?
       if @title_entry.text.strip.length == 0
         @app.alert('You must enter a title')
         return false
       end
       return true
    end
invoke()

Causes the dialog to be displayed. The invoke method does not return until the user dismisses the dialog. If the user presses OK, the edited menu item will be returned, otherwise nil will be returned.

[Source]

# File lib/sshmenu.rb, line 2613
    def invoke
      dialog = build_dialog

      while true
        response = dialog.run
        if response == Gtk::Dialog::RESPONSE_ACCEPT
          break if inputs_valid?
        else
          dialog.destroy
          return
        end
      end

      @menu.title = @title_entry.text

      dialog.destroy

      return @menu
    end
