TFontDialog class
Dialog used to select a font typeface and size.
Declaration
TFontDialog = class(TCommonDialog)Inheritance
Description
TFontDialog is a
TCommonDialog descendant which
implements a font selection dialog.
TFontDialog displays selection lists for font name, size, style, and color. It can be configured to limit the available typefaces, sizes, and visual presentations using the Options, MinFontSize and MaxFontSize properties.
At run-time, TFontDialog is mapped to the native font selection dialog used for a given platform. Use Options to enable or disable features or behaviors in the dialog. Enabling an option does not mean that it is automatically available. Some options may not be supported in the native dialog for a given platform.
When the dialog is executed, the selected font and its attributes is made available in the Font property. The OnApplyClicked event handler can be used to perform actions needed when the optional Apply button is clicked in the dialog. Please note that the Apply button is available on the GTK2, GTK3, and Windows platforms. It is not currently implemented for QT platforms.
