Section toggle
I would like to create two sections in my installer wich can't be selected together. I wan't them only to be i one of these states: both unselected. Only section A selected or only section B selected. Does someone have an example script for me?

thank you in advance!

The google keyword is 'mutually exclusive sections'.

Wonderfull google keyword. Was searching on a bunch of terms, but this hits the nail right on the spot!

Thank you very very much!!

still a little problem here, but i'm comming closer. When i add this to my script i can use it for two sections. How would a make it work for another two sections?

example:
A
B
C
D

I can choose either A or B or none of them AND
I can choose either C or D or none of them
AB and CD are independend from each other.

thx!

Simply duplicate the code, and use a second variable to keep track of the second section group.

Hi,

thank you for your guidance. I have it almost working. Problem is that selecting sectionB doesn't unselect sectionA anymore when one has selected sectionC or D
I have to manually unselect sectionA to be able to select sectionB again. Most likely something stupid i've done, but perhaps it's easily fixed. I've pasted my code below.

Function .onSelChange
  Push $0
 
  StrCmp $R9 ${-secA} check_-secA
 
    SectionGetFlags ${-secA} $0
    IntOp $0 $0 & ${SF_SELECTED}
    IntCmp $0 ${SF_SELECTED} 0 done done
      StrCpy $R9 ${-secA}
      SectionGetFlags ${-secB} $0
      IntOp $0 $0 & ${SECTION_OFF}
      SectionSetFlags ${-secB} $0
 
    Goto done
 
  check_-secA:
 
    SectionGetFlags ${-secB} $0
    IntOp $0 $0 & ${SF_SELECTED}
    IntCmp $0 ${SF_SELECTED} 0 done done
      StrCpy $R9 ${-secB}
      SectionGetFlags ${-secA} $0
      IntOp $0 $0 & ${SECTION_OFF}
      SectionSetFlags ${-secA} $0
  done:
  Pop $0
  Push $1
  StrCmp $R9 ${-secC} check_-secC
 
    SectionGetFlags ${-secC} $1
    IntOp $1 $1 & ${SF_SELECTED}
    IntCmp $1 ${SF_SELECTED} 0 done2 done2
      StrCpy $R9 ${-secC}
      SectionGetFlags ${-secD} $1
      IntOp $1 $1 & ${SECTION_OFF}
      SectionSetFlags ${-secD} $1
 
    Goto done2
 
  check_-secC:
 
    SectionGetFlags ${-secD} $1
    IntOp $1 $1 & ${SF_SELECTED}
    IntCmp $1 ${SF_SELECTED} 0 done2 done2
      StrCpy $R9 ${-secD}
      SectionGetFlags ${-secC} $1
      IntOp $1 $1 & ${SECTION_OFF}
      SectionSetFlags ${-secC} $1

  done2:
  Pop $1
FunctionEnd
