mouseLine 875

mouseLine

Usage

-- Lingo syntax

_mouse.mouseLine

// JavaScript syntax

_mouse.mouseLine;

Description

Mouse property; contains the number of the line under the pointer when the property is called

and the pointer is over a field sprite. Read-only.

Counting starts at the beginning of the field; a line is defined by Return delimiter, not by the

wrapping at the edge of the field. When the mouse pointer is not over a field sprite, the result

is -1.

The value of the

mouseLine property can change in a handler or loop. If a handler or loop uses

this property multiple times, it’s usually a good idea to call the property once and assign its value

to a local variable.

Example

This statement determines whether the pointer is over a field sprite and changes the content of

the field cast member Instructions to “Please point to a line.” when it is not:

-- Lingo syntax

if (_mouse.mouseLine = -1) then

member("Instructions").text = "Please point to a line."

end if

// JavaScript syntax

if (_mouse.mouseLine == -1) {

member("Instructions").text = "Please point to a line.";

}

This statement assigns the contents of the line under the pointer in the specified field to the

variable

currentLine:

-- Lingo syntax

currentLine = member(_mouse.mouseMember).line[_mouse.mouseLine]

// JavaScript syntax

var currentLine = member(_mouse.mouseMember).getProp("line",

_mouse.mouseLine);
