a dialog box is presented for adding, deleting or editing entries in the list.
At present no constraints may be supplied.

You can construct a string list property value by constructing a wxStringList object.

For example:

\begin{verbatim}
  myListValidatorRegistry.RegisterValidator((wxString)"stringlist",
      new wxListOfStringsListValidator);

  wxStringList *strings = new wxStringList("earth", "fire", "wind", "water", NULL);

  sheet-&gt;AddProperty(new wxProperty("fred", strings, "stringlist"));

\func{void}{wxListOfStringsListValidator}{\param{long}{ flags=0}}

Constructor.

\section{\class{wxProperty}: wxObject}\label{wxproperty}

The {\bf wxProperty} class represents a property, with a \helpref{wxPropertyValue}{wxpropertyvalue}\rtfsp
containing the actual value, a name a role, an optional validator, and
an optional associated window. 

A property might correspond to an actual C++ data member, or it
might correspond to a conceptual property, such as the width of a window.
There is no explicit data member {\it wxWindow::width}, but it may be convenient
to invent such a property for the purposes of editing attributes of the window.
The properties in the property sheet can be mapped to ``reality" by
whatever means (in this case by calling wxWindow::SetSize when the user has
finished editing the property sheet).

A validator may be associated with the property in order to ensure that this and
only this validator will be used for editing and validating the property.
An alternative method is to use the {\it role} parameter to specify what kind
of validator would be appropriate; for example, specifying ``filename" for the role
would allow the property view to find an appropriate validator at edit time.

Returns the flags for the validator.

\membersection{wxPropertyValidator::GetValidatorProperty}

\func{wxProperty *}{GetValidatorProperty}{\void}

Gets the property for the validator.

\membersection{wxPropertyValidator::SetValidatorProperty}

\func{void}{SetValidatorProperty}{\param{wxProperty *}{property}}

Sets the property for the validator.


\section{\class{wxPropertyValidatorRegistry}: wxHashTable}\label{wxpropertyvalidatorregistry}

The {\bf wxPropertyValidatorRegistry} class is used for storing validators,
indexed by the `role name' of the property, by which groups of property
can be identified for the purpose of validation and editing.

\membersection{wxPropertyValidatorRegistry::wxPropertyValidatorRegistry}

\func{void}{wxPropertyValidatorRegistry}{\void}

Constructor.

\membersection{wxPropertyValidatorRegistry::\destruct{wxPropertyValidatorRegistry}}

\func{void}{\destruct{wxPropertyValidatorRegistry}}{\void}

Destructor.

\membersection{wxPropertyValidatorRegistry::Clear}

\func{void}{ClearRegistry}{\void}

Clears the registry, deleting the validators.

\membersection{wxPropertyValidatorRegistry::GetValidator}

\func{wxPropertyValidator *}{GetValidator}{\param{wxString\&amp; }{roleName}}

Retrieve a validator by the property role name.

\membersection{wxPropertyValidatorRegistry::RegisterValidator}\label{wxpropertyvalidatorregistervalidator}

\func{void}{RegisterValidator}{\param{wxString\&amp; }{roleName}, \param{wxPropertyValidator *}{validator}}

Register a validator with the registry. {\it roleName} is a name indicating the
role of the property, such as ``filename''. Later, when a validator is chosen for
editing a property, this role name is matched against the class names of the property,
if the property does not already have a validator explicitly associated with it.


\section{\class{wxPropertyValue}: wxObject}\label{wxpropertyvalue}

The {\bf wxPropertyValue} class represents the value of a property,
and is normally associated with a wxProperty object.

A wxPropertyValue has one of the following types:

\begin{itemize}\itemsep=0pt
\item wxPropertyValueNull
\item wxPropertyValueInteger
\item wxPropertyValueReal
\item wxPropertyValueBool
\item wxPropertyValueString
\item wxPropertyValueList
\item wxPropertyValueIntegerPtr
\item wxPropertyValueRealPtr
\item wxPropertyValueBoolPtr
\item wxPropertyValueStringPtr
\end{itemize}

\membersection{wxPropertyValue::wxPropertyValue}

\func{void}{wxPropertyValue}{\void}

Default constructor.

\func{void}{wxPropertyValue}{\param{const wxPropertyValue\&amp; }{copyFrom}}

Copy constructor.

\func{void}{wxPropertyValue}{\param{char *}{val}}

Construction from a string value.

\func{void}{wxPropertyValue}{\param{long}{ val}}

Construction from an integer value. You may need to cast to (long) to
avoid confusion with other constructors (such as the Bool constructor).

\func{void}{wxPropertyValue}{\param{Bool}{ val}}

Construction from a boolean value.

\func{void}{wxPropertyValue}{\param{float}{ val}}

Construction from a floating point value.

\func{void}{wxPropertyValue}{\param{double}{ val}}

Construction from a floating point value.

\func{void}{wxPropertyValue}{\param{wxList *}{ val}}

Construction from a list of wxPropertyValue objects. The
list, but not each contained wxPropertyValue, will be deleted
by the constructor. The wxPropertyValues will be assigned to
this wxPropertyValue list. In other words, so do not delete wxList or
its data after calling this constructor.

\func{void}{wxPropertyValue}{\param{wxStringList *}{ val}}

Construction from a list of strings. The list (including the strings
contained in it) will be deleted by the constructor, so do not
destroy {\it val} explicitly.

\func{void}{wxPropertyValue}{\param{char **}{val}}

Construction from a string pointer.

\func{void}{wxPropertyValue}{\param{long *}{val}}

Construction from an integer pointer.

\func{void}{wxPropertyValue}{\param{Bool *}{val}}

Construction from an boolean pointer.

\func{void}{wxPropertyValue}{\param{float *}{val}}

Construction from a floating point pointer.

The last four constructors use pointers to various C++ types, and do not
store the types themselves; this allows the values to stand in for actual
data values defined elsewhere.

Destructor.

\membersection{wxPropertyValue::Append}

\func{void}{Append}{\param{wxPropertyValue *}{expr}}

\section{Registry classes}

A validator registry is a list of validators that can be applied to properties in a property sheet.
There may be one or more registries per property view.

\begin{itemize}\itemsep=0pt
\item \helpref{wxPropertyValidatorRegistry}{wxpropertyvalidatorregistry}
\end{itemize}


\chapter{Topic overviews}\label{overviews}

This chapter contains a selection of topic overviews.

\section{Property classes overview}\label{propertyoverview}

The property classes help a programmer to express relationships between
data and physical windows, in particular:

\begin{itemize}\itemsep=0pt
\item the transfer of data to and from the physical controls;
\item the behaviour of various controls and custom windows for particular
types of data;
\item the validation of data, notifying the user when incorrect data is entered,
or even better, constraining the input so only valid data can be entered.
\end{itemize}

With a consistent framework, the programmer should be able to use existing
components and design new ones in a principled manner, to solve many data entry
requirements.

Each datum is represented in a \helpref{wxProperty}{wxproperty}, which has a name and a value.
Various C++ types are permitted in the value of a property, and the property can store a pointer
to the data instead of a copy of the data. A \helpref{wxPropertySheet}{wxpropertysheet} represents a number of these properties.

These two classes are independent from the way in which the data is visually manipulated. To
mediate between property sheets and windows, the abstract class \helpref{wxPropertyView}{wxpropertyview} is
available for programmers to derive new kinds of view. One kind of view that is available is the \helpref{wxPropertyListView}{wxpropertylistview},
which displays the data in a Visual Basic-style list, with a small number of controls for editing
the currently selected property. Another is \helpref{wxPropertyFormView}{wxpropertyformview} which
mediates between an existing dialog or panel and the property sheet.

The hard work of mediation is actually performed by validators, which are instances of classes
derived from \helpref{wxPropertyValidator}{wxpropertyvalidator}. A validator is associated with
a particular property and is responsible for
responding to user interface events, and displaying, updating and checking the property value.
Because a validator's behaviour depends largely on the kind of view being used, there has to be
a separate hierarchy of validators for each class of view. So for wxPropertyListView, there is
an abstract class \helpref{wxPropertyListValidator}{wxpropertylistvalidator} from which concrete
classes are derived, such as \helpref{wxRealListValidator}{wxreallistvalidator} and
\rtfsp\helpref{wxStringListValidator}{wxstringlistvalidator}.

A validator can be explicitly set for a property, so there is no doubt which validator
should be used to edit that property. However, it is also possible to define a registry
of validators, and have the validator chosen on the basis of the {\it role} of the property.
So a property with a ``filename" role would match the ``filename" validator, which pops
up a file selector when the user double clicks on the property.

You don't have to define your own frame or window classes: there are some predefined
that will work with the property list view. See \helpref{Window classes}{windowclasses} for
further details.

\subsection{Example 1: Property list view}

The following code fragment shows the essentials of creating a registry of
standard validators, a property sheet containing some properties, and
a property list view and dialog or frame. RegisterValidators will be
called on program start, and PropertySheetTest is called in response to a
menu command.

Note how some properties are created with an explicit reference to
a validator, and others are provided with a ``role'' which can be matched
against a validator in the registry.

The interface generated by this test program is shown in the section \helpref{Appearance and
behaviour of a property list view}{appearance}.

\begin{verbatim}
void RegisterValidators(void)
{
  myListValidatorRegistry.RegisterValidator((wxString)"real", new wxRealListValidator);
  myListValidatorRegistry.RegisterValidator((wxString)"string", new wxStringListValidator);
  myListValidatorRegistry.RegisterValidator((wxString)"integer", new wxIntegerListValidator);
  myListValidatorRegistry.RegisterValidator((wxString)"bool", new wxBoolListValidator);
}

void PropertyListTest(Bool useDialog)
{
  wxPropertySheet *sheet = new wxPropertySheet;

  sheet-&gt;AddProperty(new wxProperty("fred", 1.0, "real"));
  sheet-&gt;AddProperty(new wxProperty("tough choice", (Bool)TRUE, "bool"));
  sheet-&gt;AddProperty(new wxProperty("ian", (long)45, "integer", new wxIntegerListValidator(-50, 50)));
  sheet-&gt;AddProperty(new wxProperty("bill", 25.0, "real", new wxRealListValidator(0.0, 100.0)));
  sheet-&gt;AddProperty(new wxProperty("julian", "one", "string"));
  sheet-&gt;AddProperty(new wxProperty("bitmap", "none", "string", new wxFilenameListValidator("Select a bitmap file", "*.bmp")));
  wxStringList *strings = new wxStringList("one", "two", "three", NULL);
  sheet-&gt;AddProperty(new wxProperty("constrained", "one", "string", new wxStringListValidator(strings)));

  wxPropertyListView *view =
    new wxPropertyListView(NULL,
     wxPROP_BUTTON_CHECK_CROSS|wxPROP_DYNAMIC_VALUE_FIELD|wxPROP_PULLDOWN);

  wxDialogBox *propDialog = NULL;
  wxPropertyListFrame *propFrame = NULL;
  if (useDialog)
  {
    propDialog = new wxPropertyListDialog(view, NULL, "Property Sheet Test", TRUE, -1, -1, 400, 500);
  }
  else
  {
    propFrame = new wxPropertyListFrame(view, NULL, "Property Sheet Test", -1, -1, 400, 500);
  }
  
  view-&gt;AddRegistry(&amp;myListValidatorRegistry);

  if (useDialog)
  {
    view-&gt;ShowView(sheet, propDialog);
    propDialog-&gt;Centre(wxBOTH);
    propDialog-&gt;Show(TRUE);
  }
  else
  {
    propFrame-&gt;Initialize();
    view-&gt;ShowView(sheet, propFrame-&gt;GetPropertyPanel());
    propFrame-&gt;Centre(wxBOTH);
    propFrame-&gt;Show(TRUE);
  }
}
\end{verbatim}

\subsection{Example 2: Property form view}

This example is similar to Example 1, but uses a property form view to
edit a property sheet using a predefined dialog box.

\begin{verbatim}
void RegisterValidators(void)
{
  myFormValidatorRegistry.RegisterValidator((wxString)"real", new wxRealFormValidator);
  myFormValidatorRegistry.RegisterValidator((wxString)"string", new wxStringFormValidator);

}

void PropertyFormTest(Bool useDialog)
{
  wxPropertySheet *sheet = new wxPropertySheet;

  sheet-&gt;AddProperty(new wxProperty("fred", 25.0, "real", new wxRealFormValidator(0.0, 100.0)));
  sheet-&gt;AddProperty(new wxProperty("tough choice", (Bool)TRUE, "bool"));
  sheet-&gt;AddProperty(new wxProperty("ian", (long)45, "integer", new wxIntegerFormValidator(-50, 50)));
  sheet-&gt;AddProperty(new wxProperty("julian", "one", "string"));
  wxStringList *strings = new wxStringList("one", "two", "three", NULL);
  sheet-&gt;AddProperty(new wxProperty("constrained", "one", "string", new wxStringFormValidator(strings)));

  wxPropertyFormView *view = new wxPropertyFormView(NULL);

  wxDialogBox *propDialog = NULL;
  wxPropertyFormFrame *propFrame = NULL;
  if (useDialog)
  {
    propDialog = new wxPropertyFormDialog(view, NULL, "Property Form Test", TRUE, -1, -1, 400, 300);
  }
  else
  {
    propFrame = new wxPropertyFormFrame(view, NULL, "Property Form Test", -1, -1, 400, 300);
    propFrame-&gt;Initialize();
  }
  
  wxPanel *panel = propDialog ? propDialog : propFrame-&gt;GetPropertyPanel();
  panel-&gt;SetLabelPosition(wxVERTICAL);
  
  // Add items to the panel
  
  (void) new wxButton(panel, (wxFunction)NULL, "OK", -1, -1, -1, -1, 0, "ok");

  (void) new wxButton(panel, (wxFunction)NULL, "Update", -1, -1, 80, -1, 0, "update");
  (void) new wxButton(panel, (wxFunction)NULL, "Revert", -1, -1, -1, -1, 0, "revert");
  panel-&gt;NewLine();
  
  // The name of this text item matches the "fred" property
  (void) new wxText(panel, (wxFunction)NULL, "Fred", "", -1, -1, 90, -1, 0, "fred");
  (void) new wxCheckBox(panel, (wxFunction)NULL, "Yes or no", -1, -1, -1, -1, 0, "tough choice");
  (void) new wxSlider(panel, (wxFunction)NULL, "Sliding scale", 0, -50, 50, 100, -1, -1, wxHORIZONTAL, "ian");
  panel-&gt;NewLine();
  (void) new wxListBox(panel, (wxFunction)NULL, "Constrained", wxSINGLE, -1, -1, 100, 90, 0, NULL, 0, "constrained");

  view-&gt;AddRegistry(&amp;myFormValidatorRegistry);

  if (useDialog)
  {
    view-&gt;ShowView(sheet, propDialog);
    view-&gt;AssociateNames();
    view-&gt;TransferToDialog();
    propDialog-&gt;Centre(wxBOTH);
    propDialog-&gt;Show(TRUE);
  }
  else
  {
    view-&gt;ShowView(sheet, propFrame-&gt;GetPropertyPanel());
    view-&gt;AssociateNames();
    view-&gt;TransferToDialog();

  }
}
\end{verbatim}

\section{Validator classes overview}\label{validatoroverview}

Classes: \helpref{Validator classes}{validatorclasses}

The validator classes provide functionality for mediating between a wxProperty and
the actual display. There is a separate family of validator classes for each
class of view, since the differences in user interface for these views implies
that little common functionality can be shared amongst validators.

\subsection{wxPropertyValidator overview}\label{wxpropertyvalidatoroverview}

Class: \helpref{wxPropertyValidator}{wxpropertyvalidator}

This class is the root of all property validator classes. It contains a small
amount of common functionality, including functions to convert between
strings and C++ values.

A validator is notionally an object which sits between a property and its displayed
value, and checks that the value the user enters is correct, giving an error message
if the validation fails. In fact, the validator does more than that, and is akin to
a view class but at a finer level of detail. It is also responsible for
loading the dialog box control with the value from the property, putting it back
into the property, preparing special controls for editing the value, and
may even invoke special dialogs for editing the value in a convenient way.

In a property list dialog, there is quite a lot of scope for supplying custom dialogs,
such as file or colour selectors. For a form dialog, there is less scope because
there is no concept of `detailed editing' of a value: one control is associated with
one property, and there is no provision for invoking further dialogs. The reader
may like to work out how the form view could be extended to provide some of the
functionality of the property list!

Validator objects may be associated explictly with a wxProperty, or they may be
indirectly associated by virtue of a property `kind' that matches validators having
that kind. In the latter case, such validators are stored in a validator registry
which is passed to the view before the dialog is shown. If the validator takes
arguments, such as minimum and maximum values in the case of a wxIntegerListValidator,
then the validator must be associated explicitly with the property. The validator
will be deleted when the property is deleted.

\subsection{wxPropertyListValidator overview}\label{wxpropertylistvalidatoroverview}

Class: \helpref{wxPropertyListValidator}{wxpropertylistvalidator}

This class is the abstract base class for property list view validators.
The list view acts upon a user interface containing a list of properties,
a text item for direct property value editing, confirm/cancel buttons for the value,
a pulldown list for making a choice between values, and OK/Cancel/Help buttons
for the dialog (see \helpref{property list appearance}{appearance}).

By overriding virtual functions, the programmer can create custom
behaviour for different kinds of property. Custom behaviour can use just the
available controls on the property list dialog, or the validator can
invoke custom editors with quite different controls, which pop up in
`detailed editing' mode.

See the detailed class documentation for the members you should override
to give your validator appropriate behaviour.

\subsection{wxPropertyFormValidator overview}\label{wxpropertyformvalidatoroverview}

This class is the abstract base class for property form view validators.
The form view acts upon an existing dialog box or panel, where either the
panel item names correspond to property names, or the programmer has explicitly
associated the panel item with the property.

By overriding virtual functions, the programmer determines how
values are displayed or retrieved, and the checking that the validator does.

See the detailed class documentation for the members you should override
to give your validator appropriate behaviour.

\section{View classes overview}\label{viewoverview}

An instance of a view class relates a property sheet with an actual window.
Currently, there are two classes of view: wxPropertyListView and wxPropertyFormView.

\subsection{wxPropertyView overview}\label{wxpropertyviewoverview}

Class: \helpref{wxPropertyView}{wxpropertyview}

This is the abstract base class for property views.

\subsection{wxPropertyListView overview}\label{wxpropertylistviewoverview}

Class: \helpref{wxPropertyListView}{wxpropertylistview}

The property list view defines the relationship between a property sheet and
a property list dialog or panel. It manages user interface events such as
clicking on a property, pressing return in the text edit field, and clicking
on Confirm or Cancel. These events cause member functions of the
class to be called, and these in turn may call member functions of
the appropriate validator to be called, to prepare controls, check the property value,
invoke detailed editing, etc.

\subsection{wxPropertyFormView overview}\label{wxpropertyformviewoverview}

Class: \helpref{wxPropertyFormView}{wxpropertyformview}

The property form view manages the relationship between a property sheet
and an existing dialog or panel.

You must first create a panel or dialog box for the view to work on.
The panel should contain panel items with names that correspond to
properties in your property sheet; or you can explicitly set the
panel item for each property.

Apart from any custom panel items that you wish to control independently
of the property-editing items, wxPropertyFormView takes over the
processing of item events. It can also control normal dialog behaviour such
as OK, Cancel, so you should also create some standard buttons that the property view
can recognise. Just create the buttons with standard names and the view
will do the rest. The following button names are recognised:

\begin{itemize}\itemsep=0pt
\item {\bf ok}: indicates the OK button. Calls wxPropertyFormView::OnOk. By default,
checks and updates the form values, closes and deletes the frame or dialog, then deletes the view.
\item {\bf cancel}: indicates the Cancel button. Calls wxPropertyFormView::OnCancel. By default,
closes and deletes the frame or dialog, then deletes the view.
\item {\bf help}: indicates the Help button. Calls wxPropertyFormView::OnHelp. This needs
to be overridden by the application for anything interesting to happen.
\item {\bf revert}: indicates the Revert button. Calls wxPropertyFormView::OnRevert,
which by default transfers the wxProperty values to the panel items (in effect
undoing any unsaved changes in the items).
\item {\bf update}: indicates the Revert button. Calls wxPropertyFormView::OnUpdate, which
by defaults transfers the displayed values to the wxProperty objects.
\end{itemize}

\section{wxPropertySheet overview}\label{wxpropertysheetoverview}

Classes: \helpref{wxPropertySheet}{wxpropertysheet}, \helpref{wxProperty}{wxproperty}, \helpref{wxPropertyValue}{wxpropertyvalue}

A property sheet defines zero or more properties. This is a bit like an explicit representation of
a C++ object. wxProperty objects can have values which are pointers to C++ values, or they
can allocate their own storage for values.

Because the property sheet representation is explicit and can be manipulated by
a program, it is a convenient form to be used for a variety of
editing purposes. wxPropertyListView and wxPropertyFormView are two classes that
specify the relationship between a property sheet and a user interface. You could imagine
other uses for wxPropertySheet, for example to generate a form-like user interface without
the need for GUI programming. Or for storing the names and values of command-line switches, with the
option to subsequently edit these values using a wxPropertyListView.

A typical use for a property sheet is to represent values of an object
which are only implicit in the current representation of it. For
example, in Visual Basic and similar programming environments, you can
`edit a button', or rather, edit the button's properties.  One of the
properties you can edit is {\it width} - but there is no explicit
representation of width in a wxWindows button; instead, you call SetSize
and GetSize members. To translate this into a consisent,
property-oriented scheme, we could derive a new class
wxButtonWithProperties, which has two new functions: SetProperty and
GetProperty.  SetProperty accepts a property name and a value, and calls
an appropriate function for the property that is being passed.
GetProperty accepts a property name, returning a property value. So
instead of having to use the usual arbitrary set of C++ member functions
to set or access attributes of a window, programmer deals merely with
SetValue/GetValue, and property names and values.
We now have a single point at which we can modify or query an object by specifying
names and values at run-time. (The implementation of SetProperty and GetProperty
is probably quite messy and involves a large if-then-else statement to
test the property name and act accordingly.)

When the user invokes the property editor for a wxButtonWithProperties, the system
creates a wxPropertySheet with `imaginary' properties such as width, height, font size
and so on. For each property, wxButtonWithProperties::GetProperty is called, and the result is
passed to the corresponding wxProperty. The wxPropertySheet is passed to a wxPropertyListView
as described elsewhere, and the user edits away. When the user has finished editing, the system calls
wxButtonWithProperties::SetProperty to transfer the wxProperty value back into the button
by way of an appropriate call, wxWindow::SetSize in the case of width and height properties.
