  11 \section{\class{wxFontPickerCtrl}}\label{wxfontpickerctrl}
  12
  13 This control allows the user to select a font. The generic implementation is
  14 a button which brings up a \helpref{wxFontDialog}{wxfontdialog} when clicked. Native implementation
  15 may differ but this is usually a (small) widget which give access to the font-chooser
  16 dialog.
  17 It is only available if \texttt{wxUSE\_FONTPICKERCTRL} is set to $1$ (the default).

  38 picker button which is completely managed by the \helpref{wxFontPickerCtrl}{wxfontpickerctrl}
  39 and which can be used by the user to specify a font (see \helpref{SetSelectedFont}{wxfontpickerctrlsetselectedfont}).
  40 The text control is automatically synchronized with button's value. Use functions defined in \helpref{wxPickerBase}{wxpickerbase} to modify the text control.}

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.}

 104
 105 \docparam{name}{Control name.}
 106
 107 \wxheading{Return value}
 108
 109 \true if the control was successfully created or \false if creation failed.

 112 \membersection{wxFontPickerCtrl::GetSelectedFont}\label{wxfontpickerctrlgetselectedfont}
 113
 114 \constfunc{wxFont}{GetSelectedFont}{\void}
 115
 116 Returns the currently selected font.
 117 Note that this function is completely different from \helpref{wxWindow::GetFont}{wxwindowgetfont}.
 118
 119
 120 \membersection{wxFontPickerCtrl::SetSelectedFont}\label{wxfontpickerctrlsetselectedfont}
 121
 122 \func{void}{SetSelectedFont}{\param{const wxFont \&}{font}}
 123
 124 Sets the currently selected font.
 125 Note that this function is completely different from \helpref{wxWindow::SetFont}{wxwindowsetfont}.
 126
 127
 128 \membersection{wxFontPickerCtrl::GetMaxPointSize}\label{wxfontpickerctrlgetmaxpointsize}
 129
 130 \constfunc{unsigned int}{GetMaxPointSize}{\void}
 131
 132 Returns the maximum point size value allowed for the user-chosen font.
 133
 134
 135 \membersection{wxFontPickerCtrl::SetMaxPointSize}\label{wxfontpickerctrlsetmaxpointsize}
 136
 137 \func{void}{GetMaxPointSize}{\param{unsigned int}{ max}}
 138
 139 Sets the maximum point size value allowed for the user-chosen font.
 140 The default value is 100. Note that big fonts can require a lot of memory and CPU time
 141 both for creation and for rendering; thus, specially because the user has the option to specify
 142 the fontsize through a text control (see wxFNTP\_USE\_TEXTCTRL), it's a good idea to put a limit
 143 to the maximum font size when huge fonts do not make much sense.

 168 direct input to member function that take a
