\membersection{wxFontData::wxFontData}

\func{}{wxFontData}{\void}

Constructor. Initializes {\it fontColour} to black, {\it showHelp} to black,
\rtfsp{\it allowSymbols} to true, {\it enableEffects} to true,
\rtfsp{\it minSize} to 0 and {\it maxSize} to 0.

\membersection{wxFontData::\destruct{wxFontData}}

\func{}{\destruct{wxFontData}}{\void}

Destructor.

\membersection{wxFontData::EnableEffects}

\func{void}{EnableEffects}{\param{bool}{ enable}}

Enables or disables `effects' under MS Windows only. This refers to the
controls for manipulating colour, strikeout and underline properties.

The default value is true.

\membersection{wxFontData::GetAllowSymbols}

\func{bool}{GetAllowSymbols}{\void}

Under MS Windows, returns a flag determining whether symbol fonts can be selected. Has no
effect on other platforms.

The default value is true.

\membersection{wxFontData::GetColour}

\func{wxColour\&}{GetColour}{\void}

Gets the colour associated with the font dialog.

The default value is black.

\membersection{wxFontData::GetChosenFont}

\func{wxFont}{GetChosenFont}{\void}

Gets the font chosen by the user if the user pressed OK (wxFontDialog::ShowModal returned wxID\_OK).

\membersection{wxFontData::GetEnableEffects}

\func{bool}{GetEnableEffects}{\void}

Determines whether `effects' are enabled under Windows. This refers to the
controls for manipulating colour, strikeout and underline properties.

The default value is true.

\membersection{wxFontData::GetInitialFont}

\func{wxFont}{GetInitialFont}{\void}

Gets the font that will be initially used by the font dialog. This should have
previously been set by the application.

\membersection{wxFontData::GetShowHelp}

\func{bool}{GetShowHelp}{\void}

Returns true if the Help button will be shown (Windows only).

The default value is false.

\membersection{wxFontData::SetAllowSymbols}

\func{void}{SetAllowSymbols}{\param{bool}{ allowSymbols}}

Under MS Windows, determines whether symbol fonts can be selected. Has no
effect on other platforms.

The default value is true.

\membersection{wxFontData::SetChosenFont}

\func{void}{SetChosenFont}{\param{const wxFont\& }{font}}

Sets the font that will be returned to the user (for internal use only).

\membersection{wxFontData::SetColour}

\func{void}{SetColour}{\param{const wxColour\&}{ colour}}

Sets the colour that will be used for the font foreground colour.

The default colour is black.

\membersection{wxFontData::SetInitialFont}

\func{void}{SetInitialFont}{\param{const wxFont\&}{font}}

Sets the font that will be initially used by the font dialog.

\membersection{wxFontData::SetRange}

\func{void}{SetRange}{\param{int}{ min}, \param{int}{ max}}

Sets the valid range for the font point size (Windows only).

The default is 0, 0 (unrestricted range).

\membersection{wxFontData::SetShowHelp}

\func{void}{SetShowHelp}{\param{bool}{ showHelp}}

Determines whether the Help button will be displayed in the font dialog (Windows only).

The default value is false.

\membersection{wxFontData::operator $=$}

\func{void}{operator $=$}{\param{const wxFontData\&}{ data}}

Assignment operator for the font data.

\section{\class{wxFontDialog}}\label{wxfontdialog}

This class represents the font chooser dialog.

\membersection{wxFontDialog::wxFontDialog}

\func{}{wxFontDialog}{\void}

\func{}{wxFontDialog}{\param{wxWindow* }{parent}}

\func{}{wxFontDialog}{\param{wxWindow* }{parent}, \param{const wxFontData\& }{data}}

Constructor. Pass a parent window, and optionally the 
\helpref{font data}{wxfontdata} object to be used to initialize the dialog
controls. If the default constructor is used, 
\helpref{Create()}{wxfontdialogcreate} must be called before the dialog can be
shown.

\membersection{wxFontDialog::Create}\label{wxfontdialogcreate}

\func{bool}{Create}{\void}

\func{bool}{Create}{\param{wxWindow* }{parent}}

\func{bool}{Create}{\param{wxWindow* }{parent}, \param{const wxFontData\& }{data}}

Creates the dialog if it the wxFontDialog object had been initialized using the
default constructor. Returns {\tt true} on success and {\tt false} if an error
occured.

\membersection{wxFontDialog::\destruct{wxFontDialog}}

\func{}{\destruct{wxFontDialog}}{\void}

Destructor.

\membersection{wxFontDialog::GetFontData}

\constfunc{const wxFontData\&}{GetFontData}{\void}

\func{wxFontData\&}{GetFontData}{\void}

Returns the \helpref{font data}{wxfontdata} associated with the font dialog.

\membersection{wxFontDialog::ShowModal}

\func{int}{ShowModal}{\void}

Shows the dialog, returning {\tt wxID\_OK} if the user pressed Ok, and 
{\tt wxID\_CANCEL} otherwise.

If the user cancels the dialog (ShowModal returns {\tt wxID\_CANCEL}), no font
will be created. If the user presses OK, a new wxFont will be created and
stored in the font dialog's wxFontData structure.
