fxruby users - Apr 2009 - Strange behaviour of FXDataTarget connected to FXTextField

Hi

I have a following small program in which I am enabling or disabling a
button depending on the presence of text in the text filed. I am using
the FXDataTarget connected to the text field. I also want to add
possibility to paste the data into text filed upon pressing right
mouse button etc. Now, everything works fine until I try to connect
the mouse button action to the text field, then the FXDataTarget stops
working. I am attaching the program; the mouse staff is commented out.
Please have a look test the program with un- and commented  lines.

Right. A widget (such as FXTextField) can only have one message target
at a time. The FXTextField cannot be connected to both the
FXDataTarget and the SEL_CHANGED handler (or the commented-out
SEL_RIGHTBUTTONPRESS handler).

Thanks I see ...
.. but if I connect my SEL_RIGHTBUTTONRELEASE handler to the
FXDataTarget instead it should receive the message from FXText (I
found out that FXTextField does not sends right button messages) ,
shouldn''t it?

I rewrote the application and SEL_CHANGED handler works but
SEL_RIGHTBUTTONRELEASE - does not.

Do I not understand something? :)

I''m pretty sure that FXDataTarget only forwards SEL_COMMAND and  
SEL_CHANGED messages to its target, so no, you wouldn''t get the  
SEL_RIGHTBUTTONRELEASE message.

If it is like that, what should be the target for the FXText so that I
can handle SEL_RIGHTBUTTONRELEASE message sent by it? Should the
target be self?

Thanks

Well, there''s nothing special about it, but I''d probably just
use an
anonymous handler, e.g.

    text_widget.connect(SEL_RIGHTBUTTONRELEASE) do
      # handle right button release on text widget
    end

Hope this helps,

Lyle

Thanks a lot. I got it and it works.
