When editing an FXTable item, if you press Escape, your changes are
cancelled.  However, when an item is selected but not being edited, the
table still traps the Escape keypress.  As a result, in the following
code, if you open the dialog and then press Escape, it closes.  But if
you open the dialog, select an item in the table, and then press Escape,
nothing happens.  Is this behavior - trapping Escape when no item is
being edited - desirable?  I would expect the dialog to close in both
cases.

 

Jeroen will need to make the decision about whether this is the
appropriate default behavior for FXTable (i.e. it's a FOX thing, not an
FXRuby thing).

 

If you had some way to know for sure that the user is not currently
editing a cell, you could just intercept the SEL_KEYPRESS message and
handle it yourself, e.g.

 

            table.connect(SEL_KEYPRESS) do |sender, sel, event|

                        if event.code == KEY_Escape && (we're not
editing a cell)

                                    true

                        else

                                    false

                        end

            end

 

The problem I'm running into is that the information that you need to
make that determination (namely, whether or not an editor window has
been constructed) isn't currently exposed to FXRuby. I will make a note
to fix that in the next release.

 

Hope this helps,

 

Lyle
