FXDialogBox and SEL_CLOSE message

[Barabba]

Hello,

I want to catch the message SEL_CLOSE from a FXDialogBox running in non
modal mode.

This is my code:

class FXTestDialog < FXDialogBox

    def initialize(owner)

        super(owner, "Test of Dialog Box",  DECOR_ALL)

        self.connect(SEL_CLOSE) do |sender, sel, event|
           p 'I am closing'
        end

   end

end


When I close the dialogbox I don't see the string 'I am closing',
because the SEL_CLOSE block is not called.  It is something missed here?

I am using FxRuby ver 1.6.12 under Linux.

I have looked into the C++ source code and seam that FXDialogBox handle SEL_CLOSE to raise Cancel message.

I don't know if it possible to implement FXTopWindow in ruby, but to handle the SEL_CLOSE message into a new window is better to inherit from FXMainWindow using the FXApp instance  as window owner.

The FxRuby  book suggest to use FXDialogBox as base class for a new window but it was confusing me.

Yes.  This simply hides the window and terminates the modal loop for the
FXDialogBox.

On FXMainWindow, a SEL_CLOSE actually deletes the window, and, if it was
the last window of the application, may also terminate the application.

You can do it either way, depending on whether your window is to be a self-
contained "main" window, or a subwindow displayed from another window (e.g.
like the file dialog).

For the former you'd use FXMainWindow, and for the latter FXDialogBox.
