; ======================================================================================================================
; Namespace: ImageButton
; Function: Create images and assign them to pushbuttons.
; Tested with: AHK 1.1.14.03 (A32/U32/U64)
; Tested on: Win 7 (x64)
; Change history: /2017-01-20/tmplinshi - added support for icon and checkbox/radio buttons
; 1.4.00.00/2014-06-07/just me - fixed bug for button caption = "0", "000", etc.
; 1.3.00.00/2014-02-28/just me - added support for ARGB colors
; 1.2.00.00/2014-02-23/just me - added borders
; 1.1.00.00/2013-12-26/just me - added rounded and bicolored buttons
; 1.0.00.00/2013-12-21/just me - initial release
; How to use:
; 1. Create a push button (e.g. "Gui, Add, Button, vMyButton hwndHwndButton, Caption") using the 'Hwnd' option
; to get its HWND.
; 2. Call ImageButton.Create() passing two parameters:
; HWND - Button's HWND.
; Options* - variadic array containing up to 6 option arrays (see below).
; ---------------------------------------------------------------------------------------------------------------
; The index of each option object determines the corresponding button state on which the bitmap will be shown.
; MSDN defines 6 states (http://msdn.microsoft.com/en-us/windows/bb775975):
; PBS_NORMAL = 1
; PBS_HOT = 2
; PBS_PRESSED = 3
; PBS_DISABLED = 4
; PBS_DEFAULTED = 5
; PBS_STYLUSHOT = 6 <- used only on tablet computers (that's false for Windows Vista and 7, see below)
; If you don't want the button to be 'animated' on themed GUIs, just pass one option object with index 1.
; On Windows Vista and 7 themed bottons are 'animated' using the images of states 5 and 6 after clicked.
; ---------------------------------------------------------------------------------------------------------------
; Each option array may contain the following values:
; Index Value
; 1 Mode mandatory:
; 0 - unicolored or bitmap
; 1 - vertical bicolored
; 2 - horizontal bicolored
; 3 - vertical gradient
; 4 - horizontal gradient
; 5 - vertical gradient using StartColor at both borders and TargetColor at the center
; 6 - horizontal gradient using StartColor at both borders and TargetColor at the center
; 7 - 'raised' style
; 2 StartColor mandatory for Option[1], higher indices will inherit the value of Option[1], if omitted:
; - ARGB integer value (0xAARRGGBB) or HTML color name ("Red").
; - Path of an image file or HBITMAP handle for mode 0.
; 3 TargetColor mandatory for Option[1] if Mode > 0, ignored if Mode = 0. Higher indcices will inherit
; the color of Option[1], if omitted:
; - ARGB integer value (0xAARRGGBB) or HTML color name ("Red").
; 4 TextColor optional, if omitted, the default text color will be used for Option[1], higher indices
; will inherit the color of Option[1]:
; - ARGB integer value (0xAARRGGBB) or HTML color name ("Red").
; Default: 0xFF000000 (black)
; 5 Rounded optional:
; - Radius of the rounded corners in pixel; the letters 'H' and 'W' may be specified
; also to use the half of the button's height or width respectively.
; Default: 0 - not rounded
; 6 GuiColor optional, needed for rounded buttons if you've changed the GUI background color:
; - RGB integer value (0xRRGGBB) or HTML color name ("Red").
; Default: AHK default GUI background color
; 7 BorderColor optional, ignored for modes 0 (bitmap) and 7, color of the border:
; - RGB integer value (0xRRGGBB) or HTML color name ("Red").
; 8 BorderWidth optional, ignored for modes 0 (bitmap) and 7, width of the border in pixels:
; - Default: 1
; ---------------------------------------------------------------------------------------------------------------
; If the the button has a caption it will be drawn above the bitmap.
