How do I make one nsi section depend on another?

In NSI, how can I make one section depend on another?

Our installer has four visible sections (components):

* Client
* Database
* Server
* Interface

All components depend on Client, so it is mandatory. In addition, Server depends on Database and will fail to install if Database is not present.

You can use the .onSelChange callback to change section states in response to a section change.

Outfile test.exe
!include Sections.nsh
!include LogicLib.nsh

Page Components
Page InstFiles

Section "Client"
SectionIn RO
SectionEnd

Section /o "Database" SEC_DB
SectionEnd

Section /o "Server" SEC_SRV
SectionEnd

Section /o "Interface"
SectionEnd


Function .onSelChange
${If} ${SectionIsSelected} ${SEC_SRV}
    !insertmacro SetSectionFlag ${SEC_DB} ${SF_RO}
    !insertmacro SelectSection ${SEC_DB}
${Else}
    !insertmacro ClearSectionFlag ${SEC_DB} ${SF_RO}
${EndIf}
FunctionEnd

Or without read-only DB section:

Function .onSelChange
var /Global HadSecSrv
${IfNot} ${SectionIsSelected} ${SEC_DB}
    ${If} $HadSecSrv <> 0
        !insertmacro UnselectSection ${SEC_SRV}
    ${EndIf}
${EndIf}
StrCpy $HadSecSrv 0
${If} ${SectionIsSelected} ${SEC_SRV} 
    StrCpy $HadSecSrv 1
    !insertmacro SelectSection ${SEC_DB}
${EndIf}
FunctionEnd
