\section{\class{wxPropertyFormValidator}}\label{wxpropertyformvalidator} The {\bf wxPropertyFormValidator} class defines a base class for form validators. By overriding virtual functions, the programmer can create custom behaviour for kinds of property. \wxheading{See also} \helpref{wxPropertyFormValidator overview}{wxpropertyformvalidatoroverview} \latexignore{\rtfignore{\wxheading{Members}}} \membersection{wxPropertyFormValidator::wxPropertyFormValidator} \func{void}{wxPropertyFormValidator}{\param{long}{ flags = 0}} Constructor. \membersection{wxPropertyFormValidator::\destruct{wxPropertyFormValidator}} \func{void}{\destruct{wxPropertyFormValidator}}{\void} Destructor. \membersection{wxPropertyFormValidator::OnCommand} \func{bool}{OnCommand}{\param{wxProperty *}{property}, \param{wxPropertyFormView *}{view}, \param{wxWindow *}{parentWindow}, \param{wxCommandEvent\& }{event}} Called when the control corresponding to the property receives a command (if not intercepted by a callback associated with the actual control). \membersection{wxPropertyFormValidator::OnCheckValue} \func{bool}{OnCheckValue}{\param{wxProperty *}{property}, \param{wxPropertyFormView *}{view}, \param{wxWindow *}{parentWindow}} Called when the view checks the property value. The value checked by this validator should be taken from the panel item corresponding to the property. \membersection{wxPropertyFormValidator::OnDisplayValue} \func{bool}{OnDisplayValue}{\param{wxProperty *}{property}, \param{wxPropertyFormView *}{view}, \param{wxWindow *}{parentWindow}} Should display the property value in the appropriate control. \membersection{wxPropertyFormValidator::OnDoubleClick} \func{bool}{OnDoubleClick}{\param{wxProperty *}{property}, \param{wxPropertyFormView *}{view}, \param{wxWindow *}{parentWindow}} Called when the control corresponding to the property is double clicked (listboxes only). \membersection{wxPropertyFormValidator::OnRetrieveValue} \func{bool}{OnRetrieveValue}{\param{wxProperty *}{property}, \param{wxPropertyFormView *}{view}, \param{wxWindow *}{parentWindow}} Should do the transfer from the property editing area to the property itself.
