Summary | Disables QuickTime visual effects. | ||||||
Introduced | 1.1.1 | ||||||
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. | ||||||

Description | Use the dontUseQTEffects property on slower machines for better visual results on slower machines when using built-in effects. Visual effects are used with the visual effect, hide, show, and unlock screen commands. By default, LiveCode uses QuickTime to produce these transition effects. However, slower machines may not be powerful enough to produce good results when using QuickTime for transition effects. Typically, this problem appears as "stuttering" transitions or transitions with strange visual artifacts such as diagonal lines moving across the stack window. If the dontUseQTEffects property is set to true, LiveCode uses its own built-in routines for visual effects, rather than QuickTime. The built-in routines, while less versatile, require less computing power and produce a good appearance on all machines.
The setting of this property has no effect on Windows or Unix systems. | ||||||
