Customizing an exsisting NSIS MUI2 page

Question

I have added a checkbox successfully to nsis installer\'s finish page defining functions for MUI_PAGE_CUSTOMFUNCTION_PRE and MUI_PAGE_CUSTOMFUNCTION_SHOW<

Answer 1

MUI1 uses InstallOptions for the Welcome and Finish pages and MUI2 uses nsDialogs.

This is documented in the MUI2 readme:

The welcome and finish page are no longer implemented using InstallOptions. Instead, the new nsDialogs plug-in is used. nsDialogs allows you to create custom pages or customize existing pages directly from the script.

Edit: Customize the page by using the nsDialogs commands in the show callback:

var Checkbox

Function MyFinishShow
${NSD_CreateCheckbox} 120u 110u 100% 10u "&Something"
Pop $Checkbox
SetCtlColors $Checkbox "" "ffffff"
FunctionEnd

Function MyFinishLeave
${NSD_GetState} $Checkbox $0
${If} $0 <> 0
    MessageBox mb_ok "Custom checkbox was checked..."
${EndIf}
FunctionEnd

!define MUI_FINISHPAGE_RUN "calc.exe" ;See note after the code...
!define MUI_PAGE_CUSTOMFUNCTION_SHOW MyFinishShow
!define MUI_PAGE_CUSTOMFUNCTION_LEAVE MyFinishLeave
!insertmacro MUI_PAGE_FINISH

Or if you are not using the existing finish page checkboxes, you can use those for custom stuff without using the show callback...
