Declaration

pascal

procedure DrawFocusRect(ADest: TFPCustomCanvas; ADestPos: TPoint; 
 ASize: TSize); override

Arguments

`ADestPos`	Position where the top-left corner of the focus rectangle is located on the canvas.
`ASize`	Contains the width and height for the focus rectangle.

Description

DrawFocusRect is an overridden method in TCDDrawerCommon. It implements the abstract virtual method introduced in the TCustomDrawer ancestor. It is used to draw a focus rectangle to the canvas specified in ADest.

ADestPos is a TPoint instance which contains the canvas coordinates (in the X and Y members) for the top-left corner of the focus rectangle.

ASize is a TSize instance which contains the width and height (in the CX and CY members) for the focus rectangle.

In TCDDrawerCommon, DrawFocusRect draws the focus rectangle as a dotted black line on a white background. Other areas on ADest are not affected in the method.
