Working with the NSIS installer and i want to set a static background image on the MUI_PAGE_INSTFILES page "MUI_PAGE_INSTFILES " thx for any help.

*edit - my others pages are already full bg image, so i want to keep the same designt.

edit 2 : in this example it is green but it using "commctrl.nsh" and so i dont know how to build all toghether .

code :
!include "MUI2.nsh"
!include "..\CommCtrl.nsh"
Caption "List View"
OutFile example1.exe
 Page custom CreatePage
!insertmacro MUI_LANGUAGE "English"
Section Install
SectionEnd
Function CreatePage
    !insertmacro MUI_HEADER_TEXT "List view control" "A SysListView32 control created by nsDialogs plugin"
  nsDialogs::Create 1018
  Pop $0
  StrCmp $0 error 0 +2
  Abort
  ${NSD_CreateListView} 0u 0u 300u 120u "ListView"
  Pop $1
  SendMessage $1 ${LVM_SETBKCOLOR}     0 0xC7EDCC # green bg for details page
  ; Insert a new item  ${NSD_LV_InsertItem} "hWnd" "iItem" "szText"
  ${NSD_LV_InsertItem} $1 0 "Item 0"
  ${NSD_LV_InsertItem} $1 1 "Item 1"
  nsDialogs::Show
FunctionEnd

Solution

You can't use nsDialogs controls on other pages but you can use the image macros:

RequestExecutionLevel User
!include "MUI2.nsh"
!include "WinMessages.nsh"
!include "nsDialogs.nsh"

!define MUI_PAGE_CUSTOMFUNCTION_SHOW ConfigureInstFilesPage
!insertmacro MUI_PAGE_INSTFILES
!insertmacro MUI_LANGUAGE "English"


Function ConfigureInstFilesPage
FindWindow $1 "#32770" "" $HWNDPARENT ; Inner dialog
System::Call 'USER32::GetClientRect(pr1, @r2)'
System::Call '*$2(i.r6,i.r7,i.r3,i.r4)'
; Tweak $6, $7, $3 and $4 with IntOp and remove ${SS_CENTERIMAGE} if desired
System::Call 'USER32::CreateWindowEx(i0, t"STATIC", p0, i ${WS_CHILD}|${WS_VISIBLE}|${SS_BITMAP}|${SS_CENTERIMAGE}, ir6, ir7, ir3, ir4, pr1, p0, p0, p0)p.r5'
File "/OName=$Pluginsdir\ifp.bmp" "${NSISDIR}\Contrib\Graphics\Header\win.bmp"
${NSD_SetBitmap} $5 "$Pluginsdir\ifp.bmp" $6
FunctionEnd

NSIS was never designed to support full background images. The best option is probably to use Graphical Installer but it is possible to hack something up yourself:

RequestExecutionLevel User
!include "MUI2.nsh"
!include "WinMessages.nsh"
!include "nsDialogs.nsh"


#!define MUI_HEADER_TRANSPARENT_TEXT ; Set this if you don't want header text
!define MUI_TEXTCOLOR 000066
!define MUI_BGCOLOR 667788
!define TEXTCOLOR 0x${MUI_TEXTCOLOR}
#!define BGCOLOR "0x${MUI_BGCOLOR}"
!define BGCOLOR Transparent ; Setting this to "Transparent" only works partially and requires some hacks...
