Added ControlsFlipped Boolean property (read-only): True if the controls have been flipped.After the form has been shown, the property is reset to False automatically. Added FlipControlsOnShow Boolean property: If True (the default setting if RightToLeft is True), controls on the form will be flipped the next time the form is shown.The RightToLeft directive determines the value of this property. Added RightToLeft Boolean property (read-only): True if right-to-left text alignment and reading order is enabled on the form.Changes to TSetupForm (the class used for custom forms):.Controls created on custom wizard pages will be flipped automatically after the InitializeWizard event function returns, and controls created on custom forms will, by default, be flipped the first time the form is shown. The control flipping that is performed when RightToLeft=yes is mostly transparent, normally requiring no changes to existing code.Right-to-left-related Pascal Scripting changes:.Uninstall now supports custom message constants ( ) like Setup.

If set to yes, text alignment and reading order will be reversed (with some intentional exceptions), and controls will be arranged from right to left ("flipped").
