Make CheckBox's background transparent when XPStyle is on
Hello

Is it possible to make a Checkboxes background transparent when XPStyle is on?

The following simple code can make the Checkbox background transparent but ONLY if XPStyle is set to off.

Is there a way to get the checkbox's background transparent while keeping XPStyle on? I really hope so, otherwise I have big problems. I'm open to really out there ideas, no matter how involved they are.

If theres no way, is it possible to alter the opacity of the checkbox background - maybe I can make it slightly transparent(50%)?

!include "LogicLib.nsh"
!include "MUI2.nsh"
!include WinMessages.nsh

OutFile "abc.exe"
Page Custom CustomPageInitialise

XPStyle on

Function CustomPageInitialise
    nsDialogs::Create 1018
    Pop $0
    SetCtlColors $0 0xFF0000 0x00FF00

    ${NSD_CreateCheckbox} 25u 20u 100% 20u "Version 8"
    Pop $1
    SetCtlColors $1 0xFF0000 transparent                        # Set tranparent color for control 
    ${NSD_AddExStyle} $1 ${WS_EX_TRANSPARENT}|${WS_EX_TOPMOST}  # Add special style 

    nsDialogs::Show
FunctionEnd

Short answer: No

Long answer: There is some bug in drawing (handling WM_PAINT) message in this control so if you really want to have transparent checkboxes you need to subclass control and handle everything manually - try to write C/C++ plug-in for this.

Or you can try my tool - see signature :)
