Dear All,

While this is not my first nsis script, I think I have not grabbed the full NSIS spirit yet..., and I am ckoking on this seemingly very simple problem:

My install script needs an user-selectable section, with an user-selectable option. By default, this option is checked or not depending on the value of a registry key. Obviously, if the section is not selected, the option should be grayed out. The action of this section (if selected) is something like:
"execwait myprog.exe -myoption" or "execwait myprog" depending if the option is checked or not.

I tried using sections inside sections (does not work), then SectionGroups. But I have not been able to to get a consistent checking logic.

Any help would be *really* welcome!

Michel

Something like this I guess,

code:
!include "Sections.nsh"
!include "logiclib.nsh"

Section "MyProg" sec1
#
SectionEnd

Section /o "MyOption" sec2
#
SectionEnd

Function .onSelChange
SectionGetFlags ${sec1} $R0
IntOp $R0 $R0 & ${SF_SELECTED}

${If} $R0 == ${SF_SELECTED}
    !insertmacro ClearSectionFlag ${sec2} ${SF_RO}
${ElseIf} $R0 != ${SF_SELECTED}
    !insertmacro UnSelectSection ${sec2}
    !insertmacro SetSectionFlag ${sec2} ${SF_RO}
${EndIf}
FunctionEnd

Thanks a lot, Red Wine for your fast++ answer! At least I have now a working solution.

But could it be possible to have "MyOption" indented, like when using SectionGroup? This makes sense, as MyOption is a MyProg option, not an install option.

Again thanks,

Michel

Solution:
As sinse section indexes is sequential, it possible simple iterate them from first section ("Common") till <Section Group End> flag is occured:

code:

Function ReCheckSection
 
 Var /Global fNextSection
 Var /Global IsSelected

 Pop $fNextSection

 SectionGetFlags $fNextSection $IsSelected
 IntOp $IsSelected $IsSelected & ${SF_SELECTED}

 IntOp $fNextSection $fNextSection + 1

 ${DoUntil} ${SectionIsSectionGroupEnd} $fNextSection 
 
	${If} $IsSelected == ${SF_SELECTED}
    !insertmacro ClearSectionFlag $fNextSection ${SF_RO}
  ${ElseIf} $R0 != ${SF_SELECTED}
    !insertmacro UnSelectSection $fNextSection
    !insertmacro SetSectionFlag $fNextSection ${SF_RO}
  ${EndIf}

  IntOp $fNextSection $fNextSection + 1
${LoopUntil} ${SectionIsSectionGroupEnd} $fNextSection
	


FunctionEnd


Function .onSelChange

; First section:
Push ${common}	
Call ReCheckSection	
	
FunctionEnd
