Re: [wxperl-users] Perl validators

[James L. <jl...@bi...>]

DH,

No, not to validate Perl, but to implement wxValidators in Perl.

wxValidators allow the association of a variable (in our case, a Perl
variable) with a control so that the control gets automatically populated
with the contents of the variable, and the variable gets automatically
updated when the OK button is clicked on the dialog (and NOT updated if the
Cancel button is clicked).

In addition, the validator can have validation associated with it, which
gets called when the wxDialog->Validate method is called.

This all happens automatically if the control is on a wxDialog-derived
window, and can be implemented manually with a few Wx function/method calls
if the control is on a frame.

For more details, there's good documentation on wxValidators in the
wxWindows docs.

Does this make more sense now?

Regards,

James
