Detailed Description

This control allows the user to select a font.

The generic implementation is a button which brings up a wxFontDialog when clicked. Native implementation may differ but this is usually a (small) widget which give access to the font-chooser dialog. It is only available if wxUSE_FONTPICKERCTRL is set to 1 (the default).

Styles

This class supports the following styles:

• wxFNTP_DEFAULT_STYLE:
  The default style: wxFNTP_FONTDESC_AS_LABEL | wxFNTP_USEFONT_FOR_LABEL.
• wxFNTP_USE_TEXTCTRL:
  Creates a text control to the left of the picker button which is completely managed by the wxFontPickerCtrl and which can be used by the user to specify a font (see SetSelectedFont). The text control is automatically synchronized with button's value. Use functions defined in wxPickerBase to modify the text control.
• wxFNTP_FONTDESC_AS_LABEL:
  Keeps the label of the button updated with the fontface name and the font size. E.g. choosing "Times New Roman bold, italic with size 10" from the fontdialog, will update the label (overwriting any previous label) with the "Times New Roman, 10" text.
• wxFNTP_USEFONT_FOR_LABEL:
  Uses the currently selected font to draw the label of the button.

Events emitted by this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxFontPickerEvent& event)

Event macros for events emitted by this class:

• EVT_FONTPICKER_CHANGED(id, func):
  The user changed the font selected in the control either using the button or using text control (see wxFNTP_USE_TEXTCTRL; note that in this case the event is fired only if the user's input is valid, i.e. recognizable).

Constructor & Destructor Documentation

wxFontPickerCtrl::wxFontPickerCtrl

(

)

wxFontPickerCtrl::wxFontPickerCtrl	(	wxWindow *	parent,
		wxWindowID	id,
		const wxFont &	font = wxNullFont,
		const wxPoint &	pos = wxDefaultPosition,
		const wxSize &	size = wxDefaultSize,
		long	style = wxFNTP_DEFAULT_STYLE,
		const wxValidator &	validator = wxDefaultValidator,

Member Function Documentation

bool wxFontPickerCtrl::Create	(	wxWindow *	parent,
		wxWindowID	id,
		const wxFont &	font = wxNullFont,
		const wxPoint &	pos = wxDefaultPosition,
		const wxSize &	size = wxDefaultSize,
		long	style = wxFNTP_DEFAULT_STYLE,
		const wxValidator &	validator = wxDefaultValidator,
		const wxString &	name = wxFontPickerCtrlNameStr
	)

Creates this widget with given parameters.

Parameters:

parent	Parent window, must not be non-NULL.
id	The identifier for the control.
font	The initial font shown in the control. If wxNullFont is given, the default font is used.
pos	Initial position.
size	Initial size.
style	The window style, see wxFNTP_* flags.
validator	Validator which can be used for additional date checks.
name	Control name.

Returns:

true if the control was successfully created or false if creation failed.

unsigned int wxFontPickerCtrl::GetMaxPointSize

(

)

const

Returns the maximum point size value allowed for the user-chosen font.

wxFont wxFontPickerCtrl::GetSelectedFont

(

)

const

Returns the currently selected font.

Note that this function is completely different from wxWindow::GetFont.

void wxFontPickerCtrl::SetMaxPointSize

(

unsigned int

max

)

Sets the maximum point size value allowed for the user-chosen font.

The default value is 100. Note that big fonts can require a lot of memory and CPU time both for creation and for rendering; thus, specially because the user has the option to specify the fontsize through a text control (see wxFNTP_USE_TEXTCTRL), it's a good idea to put a limit to the maximum font size when huge fonts do not make much sense.

void wxFontPickerCtrl::SetSelectedFont

(

const wxFont &

font

)

Sets the currently selected font.

Note that this function is completely different from wxWindow::SetFont.
