wxFontPickerCtrl

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).

Derived from

wxPickerBase
wxControl
wxWindow
wxEvtHandler
wxObject

Window 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.

Event handling

To process a font picker event, use these event handler macros to direct input to member functions that take a wxFontPickerEvent argument.

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).

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, const wxString& name = "fontpickerctrl")

Initializes the object and calls Create with all the parameters.

wxFontPickerCtrl::Create

bool 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 = "fontpickerctrl")

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.

Return value

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

wxFontPickerCtrl::GetSelectedFont

wxFont GetSelectedFont() const

Returns the currently selected font. Note that this function is completely different from wxWindow::GetFont.

wxFontPickerCtrl::SetSelectedFont

void SetSelectedFont(const wxFont &font)

Sets the currently selected font. Note that this function is completely different from wxWindow::SetFont.

wxFontPickerCtrl::GetMaxPointSize

unsigned int GetMaxPointSize() const

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

wxFontPickerCtrl::SetMaxPointSize

void GetMaxPointSize(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.
