TCanvas.RoundRect

Draws a rectangle with rounded corners at the specified position.

Declaration

Source position: graphics.pp line 1156

public procedure TCanvas.RoundRect(

X1: Integer;

Y1: Integer;

X2: Integer;

Y2: Integer;

RX: Integer;

RY: Integer

); virtual; procedure TCanvas.RoundRect(

const Rect: TRect;

RX: Integer;

RY: Integer

);

Arguments

`X1`		Left coordinate for the top, left corner of the rectangle.
`Y1`		Top coordinate for the top, left corner of the rectangle.
`X2`		Right coordinate for the bottom, right corner of the rectangle.
`Y2`		Bottom coordinate for the bottom, right corner of the rectangle.
`RX`		Width of the ellipse a quarter of which is drawn in the rounded corners. Note that this is the full width rather than the radius as suggested by the variable name.
`RY`		Height of the ellipse a quarter of which is drawn in the rounded corners. Note that this is the full height rather than the radius as suggested by the variable name.

Arguments

`Rect`		TRect instance with the coordinates for the rectangle vertices.
`RX`		Width of the ellipse a quarter of which is drawn in the rounded corners. Note that this is the full width rather than the radius as suggested by the variable name.
`RY`		Height of the ellipse a quarter of which is drawn in the rounded corners. Note that this is the full height rather than the radius as suggested by the variable name.

Description

RoundRect is an overloaded method in TCanvas used to draw a rectangle with rounded corners. The overloaded variants allow the coordinates to be specified as either:

Four separate Integer values representing the top, left, bottom, and right vertices for the shape (X1, Y1, X2, Y2).
A TRect instance where the vertices are represented as either four Integers, two TPoint instances for TopLeft and BottomRight, or a vector using the TArray4IntegerType (Rect).

RX and RY contain the width and height (respectively) for an ellipse used to draw arc segments for the rounded corners on the rectangular shape.

RoundRect (like Rectangle) draws an outline (or borders) for the shape using the mode, style and width defined in Pen. The rounded rectangle is also filled using the style, color and/or bitmap defined in Brush.

RoundRect calls the routine in the LCL interface used to implement the method for the current widgetset.
