Notifies the parent object about any font appearance change.

Declaration

property OnChange: TNotifyEvent read; write;

Remarks

Warning

Do not handle the OnChange event of a TdxFontOptions class instance used as a part of a DevExpress component. DevExpress components handle the OnChange event to track font setting changes and redraw visual elements accordingly.

The OnChange event occurs every time one of the following properties changes its value outside a BeginUpdate/EndUpdate block:

Bold

Specifies if the bold font attribute is applied to text.

Charset

Specifies the selected character set of the active font typeface.

Height

Specifies font height, in pixels.

Italic

Specifies if the italic font attribute is applied to text.

Name

Specifies font typeface.

Pitch

Specifies if all characters in the current font have the same width.

Quality

Specifies font rendering quality level.

Size

Specifies size of the current font, in typographic points.

StrikeOut

Specifies if the strikeout font attribute is applied to text.

Style

Specifies the current state of all font attributes applied to text.

Underline

Specifies if the underline font attribute is applied to text.

The EndUpdate procedure raises the OnChange event only once.
