Definition

Prompts the user to choose a font from among those installed on the local computer.

Header: #include <xtd/forms/font_dialog>

Namespace: xtd::forms

Library: xtd.forms

Remarks: The inherited member show_dialog must be invoked to create this specific common dialog box. hook_proc can be overridden to implement specific dialog box hook functionality.; When you create an instance of font_dialog, some of the read/write properties are set to initial values. For a list of these values, see the font_dialog constructor.
