Name: qtEffects

Type: function

Syntax: the qtEffects

Syntax: qtEffects()

Summary:

<return|Returns> a list of <QuickTime> special effects.

Introduced: 1.1

OS: mac

Platforms: desktop

Example:

the qtEffects

Example:

if field "Effect" is not among the lines of the qtEffects then beep

Returns:

The <qtEffects> <function> <return|returns> a list of installed effect

names, one per line.

Description:

Use the <qtEffects> function to find out which <QuickTime> special

effects are currently installed, and can therefore be used with the

<visual effect> command.

The effects returned by the <qtEffects> <function> can be used as visual

effects with the <visual effect>, <unlock screen>, <show> and <hide>

commands.

Changes:

The use of <QuickTime> was deprecated in version 8.1 of LiveCode with

new defaults for <dontUseQT> and <dontUseQTEffects> as true on all

systems apart from pre OS X 10.8. The Windows build of LiveCode no

longer supports any <QuickTime> features and setting the <dontUseQT> and

<dontUseQTEffects> will have no effect. Additionally <QuickTime> does

not include 64 bit support and therefore can not be supported on OS X 64

bit builds of LiveCode.
