; AHK 1.1+
; ======================================================================================================================
; Function: Auxiliary object to color controls on WM_CTLCOLOR... notifications.
; Supported controls are: Checkbox, ComboBox, DropDownList, Edit, ListBox, Radio, Text.
; Checkboxes and Radios accept only background colors due to design.
; Namespace: CtlColors
; Tested with: 1.1.25.02
; Tested on: Win 10 (x64)
; Change log: 1.0.04.00/2017-10-30/just me - added transparent background (BkColor = "Trans").
; 1.0.03.00/2015-07-06/just me - fixed Change() to run properly for ComboBoxes.
; 1.0.02.00/2014-06-07/just me - fixed __New() to run properly with compiled scripts.
; 1.0.01.00/2014-02-15/just me - changed class initialization.
; 1.0.00.00/2014-02-14/just me - initial release.
