TdxFillOptions.OnChange Event

Notifies the parent object about any fill setting change.

Declaration

property OnChange: TNotifyEvent read; write;

Remarks

Warning

Do not handle the OnChange event of a TdxFillOptions class instance used as a part of a DevExpress component. DevExpress components handle the OnChange event to track area fill 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:

Color

Specifies primary fill color.

Color2

Specifies secondary fill color.

GradientMode

Specifies gradient fill direction in Gradient mode.

HatchStyle

Specifies hatch pattern in Hatch fill mode.

Mode

Specifies the active fill mode.

Texture

Stores the image used to fill an area in Texture mode.

The EndUpdate procedure raises the OnChange event only once.
