#include <wx/validate.h>
A validator has three major roles:
Validators can be plugged into controls dynamically.
To specify a default, "null" validator, use wxDefaultValidator.
For more information, please see wxValidator Overview.
wxPython Note: If you wish to create a validator class in wxPython you should derive the class from wxPyValidator
in order to get Python-aware capabilities for the various virtual methods.
Predefined objects/pointers: wxDefaultValidator
Public Member Functions | |
wxValidator () | |
Constructor. | |
virtual | ~wxValidator () |
Destructor. | |
virtual wxObject * | Clone () const |
All validator classes must implement the Clone() function, which returns an identical copy of itself. | |
wxWindow * | GetWindow () const |
Returns the window associated with the validator. | |
void | SetWindow (wxWindow *window) |
Associates a window with the validator. | |
virtual bool | TransferFromWindow () |
This overridable function is called when the value in the window must be transferred to the validator. | |
virtual bool | TransferToWindow () |
This overridable function is called when the value associated with the validator must be transferred to the window. | |
virtual bool | Validate (wxWindow *parent) |
This overridable function is called when the value in the associated window must be validated. | |
Static Public Member Functions | |
static void | SetBellOnError (bool doIt=true) |
This functions switches on or turns off the error sound produced by the validators if an invalid key is pressed. |
wxValidator::wxValidator | ( | ) |
Constructor.
virtual wxValidator::~wxValidator | ( | ) | [virtual] |
Destructor.
virtual wxObject* wxValidator::Clone | ( | ) | const [virtual] |
All validator classes must implement the Clone() function, which returns an identical copy of itself.
This is because validators are passed to control constructors as references which must be copied. Unlike objects such as pens and brushes, it does not make sense to have a reference counting scheme to do this cloning because all validators should have separate data.
Reimplemented in wxGenericValidator, and wxTextValidator.
wxWindow* wxValidator::GetWindow | ( | ) | const |
Returns the window associated with the validator.
static void wxValidator::SetBellOnError | ( | bool | doIt = true |
) | [static] |
This functions switches on or turns off the error sound produced by the validators if an invalid key is pressed.
void wxValidator::SetWindow | ( | wxWindow * | window | ) |
Associates a window with the validator.
This function is automatically called by wxWidgets when creating a wxWindow-derived class instance which takes a wxValidator reference.
E.g.
new wxTextCtrl(this, wxID_ANY, wxEmptyString, wxDefaultPosition, wxDefaultSize, 0, wxTextValidator(wxFILTER_ALPHA, &g_data.m_string));
virtual bool wxValidator::TransferFromWindow | ( | ) | [virtual] |
This overridable function is called when the value in the window must be transferred to the validator.
Reimplemented in wxGenericValidator, and wxTextValidator.
virtual bool wxValidator::TransferToWindow | ( | ) | [virtual] |
This overridable function is called when the value associated with the validator must be transferred to the window.
Reimplemented in wxGenericValidator, and wxTextValidator.
virtual bool wxValidator::Validate | ( | wxWindow * | parent | ) | [virtual] |
This overridable function is called when the value in the associated window must be validated.
parent | The parent of the window associated with the validator. |
Reimplemented in wxTextValidator.
