Hi all,
I''m working on a dialog box for a SketchUp plug-in using wxSU with
several text
controls that accept numerical input only and need a little help with the
validators.
After going through the docs for wxRuby and wxWidgets I tried the following:
class SpurGearDialog < Wx::Dialog
attr_accessor :gear_teeth
def create_gear_parameter_controls
...
#set validators
val = Wx::TextValidator.new(Wx::FILTER_INCLUDE_CHAR_LIST, @gear_teeth)
val.set_includes(@arr_int)
@tc_gTeeth.set_validator(val)
...
end
end
With @tc_gTeeth being the text control, @gear_teeth the instance variable that I
want the validator to save data to and @arr_int is my list of acceptable
characters.
When I attempt to open the dialog box, SketchUp crashes at the third line. I
found I can only get the validator to work by removing @gear_teeth when creating
the validator. However, if I do this I do not see how the validator can transfer
data between the control and my dialog class.
I''m a Ruby newbie so the problem might be my code but if not, is there
a way to
get data from the control using validators in wxRuby or is data transfer just
not supported at this time?
TIA!
Walter

You need to put an attr_reader on your dialog class, for your tc_gTeeth. Afterwhich, once your dialog is accepted, you use myDialog.tc_gTeeth.value to retrieve the value that the user has inputed.

It would appear then that validators are not fully implemented in wxRuby. From the wxWidgets docs, I think it''s possible to have a public String variable in the dialog class that the validator sends the value of the text control to. Basically then you can do MyDialog.my_variable without dealing directly with the dialog controls. If that''s not possible in wxRuby I''ll go ahead and do as you suggest and set up accessors for the text controls.
