I'm trying to add a checkbox to the welcome screen of my NSIS uninstaller, but I'm having trouble finding an example. From the documentation for MUI2 I can't find any custom functions that can be run on the welcome page.
It looks like the finish page is more easy to customize based on the documentation and other answer s I've found.
Is there a way to customize the Welcome Page? If not, what are the other options for accomplishing the intent?
The MUI(1) documentation you linked to has a note about how you can customize the welcome page in the pre/show callbacks. With MUI2 you can add controls in the show callback. See the nsDialogs documentation for more information about these custom controls...
!include MUI2.nsh
!insertmacro MUI_PAGE_INSTFILES
!define MUI_PAGE_CUSTOMFUNCTION_SHOW un.ModifyUnWelcome
!define MUI_PAGE_CUSTOMFUNCTION_LEAVE un.LeaveUnWelcome
!insertmacro MUI_UNPAGE_WELCOME
!insertmacro MUI_UNPAGE_INSTFILES
!insertmacro MUI_LANGUAGE English
Var mycheckbox ; You could just store the HWND in $1 etc if you don't want this extra variable
Function un.ModifyUnWelcome
${NSD_CreateCheckbox} 120u -18u 50% 12u "Do something special"
Pop $mycheckbox
SetCtlColors $mycheckbox "" ${MUI_BGCOLOR}
${NSD_Check} $mycheckbox ; Check it by default
FunctionEnd
Function un.LeaveUnWelcome
${NSD_GetState} $mycheckbox $0
${If} $0 <> 0
MessageBox mb_ok "I'm special"
${EndIf}
FunctionEnd
Section testuninstaller

WriteUninstaller "$pluginsdir\u.exe"
ExecWait '"$pluginsdir\u.exe" _?=$pluginsdir'
