How to enable/disable an optional section with code?

jeffadams78 · 25th September 2009, 19:17

I have an optional section, but I want to enable/disable it based on another choice the user has made (not the normal "select what to install" page).

What variable do I set, or macro do I call, etc?

Here's what I want:

code:


Section "FirstSection"

  ${If} $MYVAR == 1

    ; Enable SecondSection

  ${Else}

    ; Disable SecondSection

  ${EndIf}

SectionEnd



Section /o "SecondSection"

  ; does some stuff

SectionEnd

My google-fu must be weak today because this seems like it would be pretty common but I can't find any hints out there.

You can use SectionSetFlags to enable / disable a section using the ${SF_RO} flag.

BTW, you have to set the flag before the components page is shown, or in the .onSelChange Function

Thanks for the tip! Once I knew what to search for, I found this wiki page:

http://nsis.sourceforge.net/Managing...ons_on_Runtime

Hmm, it isn't showing the URL, but the wiki page is entitled "Managing Sections on Runtime".
