System.UITypes unit

Delphi compatibility unit with GUI and image-related types.

The System.UITypes unit contains UI (User Interface) related types: colors, cursor shapes, modal dialog results. These types have been isolated so they can be used in programs that need them without the need for including a specific UI framework.

Classes and records

`TAlphaColorF`	record	Handles TAlphaColor values where the ARGB channels are specified using single precision floating point values.
`TAlphaColors`	record	Provides access to TAlphaColor values or their ARGB channel values.
`TColorHelper`	helper
`TColorRec`	record	Record type used to access color names and values.

Procedures and functions

`IsAbortResult`	function	Indicates whether the specified modal result value is one of the values returned when a dialog has been cancelled.
`IsAnAllResult`	function	Indicates whether the specified modal result value is one of the values which include the "To All" qualifier.
`IsNegativeResult`	function	Indicates whether the specified modal result value is a negative result where a dialog has not been completed successfully.
`IsPositiveResult`	function	Indicates whether the specified modal result value is a positive result where a dialog has been completed successfully.
