ISHANDLE

Purpose:

Returns a positive integer if the input is a text or shape handle.

ISHANDLE(val)

val

A series, scalar or string value to test.

100 if the input is a shape handle, 200 if the input is a text handle, else 0.

W1: gsin(100, .01);

h = rectdraw(W1, 0.2, -0.5, 0.6, 1.0);

a = ishandle(h)

a == 100

The value 100 indicates the input is a handle to a shape object.

W1: gsin(100, .01);

h = text(W1, 0.2, 1.0, "Example Text");

b = ishandle(h)

b == 200

The value 200 indicates the input is a handle to a text object.

h = 100

c = ishandle(h)

c == 0

The value 0 indicates the input is not a handle to a shape or text object.

See FINDHANDLE to obtain the handles for specific graphic objects.
