FINDSHAPE

Purpose:

Finds shape handles based on property values.

Syntax:

FINDSHAPE(

win1, ..., winN, "property1", value1, …, "propertyN", valueN)

winN	-	Optional. The target windows that contains the graphic objects. Defaults to the entire worksheet.
"propertyN"	-	Optional. A string, one or more property names to identify the graphics handle.
valueN	-	Optional. An integer, string, real or series value associated with the preceding property name.

Returns:

A series of shape handles (ellipses, lines, polygons or rectangles) that match the property name/value pairs.

Example:

h = findshape(W1)

returns an array of handles to all shape objects in W1. The array is empty if no shape objects exist in the window.

Example:

h = findshape(W1, "color", lred)

h.color = yellow;

Returns an array of handles to all shape objects in W1 with a border color of light red and sets the border color of those shapes to yellow.

Example:

h = findshape(W1, W2, "color", lred, "shape", "ellipse")

h.fill = lgreen;

Returns an array of handles to all ellipse objects in W1 and W2 with a border color of light red and sets the interior color of those objects to light green.

Example:

W1: gsin(100, 1/100);

h1 = linedraw(W1, 0.0, 0.0, 1.0, 1.0);h1.tag = "t1";

h2 = rectdraw(W1, 0.2, -1.2, 0.8, -0.5);h2.tag = "t2";

h3 = findshape(W1, "tag", "t1");

h4 = findshape(W1, "tag", "t2");

h3[1] == h1;

h3[1].shape == "Lines";

h4[1] == h2;

h4[1].shape == "Rectangle"

Returns the shape handles based on the tag string property and displays the shape type strings. The returned handles are one element series.

Remarks:

FINDSHAPE is limited to locating shape objects. See FINDTEXT to locate text objects and FINDHANDLE to locate all graphic objects.

Any combination of "property name" / values can be used to located shape objects. Below is a partial list of property names:

Name	Type	Description
x	real	x coordinate
y	real	y coordinate
tag	string	object identifier
xor	integer	xor background flag
fill	integer	background color
lock	integer	lock interactive movement
type	string	type of object, "shape" or "text"
color	integer	border color or text color
focus	integer	target overlay focus
match	integer	overplot number to match color
shape	string	readonly type of shape, "ellipse", "line", "polygon", "rectangle", "text"
style	integer	border line style
width	integer	border width
coords	series	object coordinates as a series
handle	integer	object handle
tagnum	integer	same as object handle
target	integer	object coordinate target, glass, paper, etc.
winnum	integer	readonly window number of object target
showtag	integer	show object string tag
visible	integer	object visibility
position	series	readonly bounding box coordinates of the object in window coordinates, lower left x coordinate, y coordinate, height and width
devposition	series	readonly bounding box coordinates of the object in device coordinates

Specific properties can be set and queried using the handle.property dot syntax.

See ARROWDRAW to draw an arrow line.

See ELLIPSEDRAW to draw an ellipse.

See LINEDRAW to draw one or more line segments.

See POLYGONDRAW to draw a closed polygon.

See RECTDRAW to draw a rectangle.

See TEXT to draw text.
