Hit-Testing Pictures

This section describes the GXHitTestPicture function. To hit-test a picture, this function

• hit-tests each shape contained in the picture
• compiles a list of shapes that were hit
• selects one of the shapes using criteria you provide
• provides information about the shape in the picture that was hit

For more information about how QuickDraw GX hit-tests shapes, see the chapter "Shape Objects" and the chapter "Transform Objects" in Inside Macintosh: QuickDraw GX Objects.
