Description

Message that informs about an upcoming style change.

This message is sent when you:

• Load a new style into a TStyleBook that is not using a style manager.
• Change the resource of a TStyleBook.
• Update the style for all registered scenes of a style manager.

  Note: If registered scenes are already using an up-to-date style, no TBeforeStyleChangingMessage message is sent.

TBeforeStyleChangingMessage is always followed by a TStyleChangedMessage message.
