; Namespace: CCButton |
|
; Function: Helper class for colored captions on themed pushbuttons. |
|
; AHK version: 1.1.09.04 (U32) |
|
; Language: English |
|
; Version: 1.0.00.00/2013-04-27/just me |
|
; ====================================================================================================================== |
|
; How to use: To register a GUI pushbutton call |
|
; CCButton.Attach() |
|
; passing two parameters: |
|
; Hwnd - HWND of the GUI control (Integer) |
|
; Color - HTML color name or RGB color value (RRGGBB) (String/Integer) |
|
; To unregister a button call |
|
; CCButton.Detach() |
|
; passing one parameter: |
|
; Hwnd - see above |
|
; Remarks: All attached buttons will be subclassed. |
|
; Advantages: Properly drawn coloured captions on themed pushbuttons. |
|
; No pale borders on coloured backgrounds. |
|
; Disadvantages: Loss of animation on button state changes and certain states (Vista+). |
