createEllipticRgn

Syntax

region createEllipticRgn(int x1, int y1, int x2, int y2)

Arguments

x1
The x coordinate (in DBUs) of the upper-left corner of the bounding box of the ellipse.
y1
The y coordinate (in DBUs) of the upper-left corner of the bounding box of the ellipse.
x2
The x coordinate (in DBUs) of the lower-right corner of the bounding box of the ellipse.
y2
The y coordinate (in DBUs) of the lower-right corner of the bounding box of the ellipse.

Return

Return an elliptic region (see comments)

Description

Allows to define an elliptic visual region, that can be for instance handled by the functions refreshRgn or setDialogRegion

Example

setDialogRegion(createEllipticRgn(20,20,300,200));

Comments

"region" correspond to a particular FM type or object that might need to be better documented or defined. You can't directly cast it to an integer, despite it behaves like an integer.
