Force a section if sectiongroup is selected

Hi,

Is it possible to force the selection of a section if its parent SectionGroup is checked?

1. Do you want make section name show in bold (is this "force the selection of a section")?
2. Do you want force selection at runtime?
3. Do you want force selection of all checked sections?

In fact, I have 2 sectionsgroups.

The first sectiongroup named "program1" contains 3 sections:
- program binaries
- shortcut on desktop
- shortcut in start menu

I want to prevent a user to check "shortcut on desktop" or "shortcut in start menu" without checking "program binaries"

I can't use SectionIn RO because I want the users to be able to uncheck the whole SectionGroup.

Try this:

!define LOGICLIB_SECTIONCMP

!include Sections.nsh

!include logiclib.nsh



var prevcond

...

SectionGroup "Group" SG

Section "SG1" sg1

SectionEnd



Section "SG2" sg2

SectionEnd



Section "SG3" sg3

SectionEnd

SectionGroupEnd

...

Function .onSelChange

${If} $prevcond != "checked"

   ${Unless} ${SectionIsSelected} ${sg1}

      ${If} ${SectionIsSelected} ${sg2}

      ${OrIf} ${SectionIsSelected} ${sg3}

         !insertmacro SelectSection ${sg1}

      ${EndIf}

   StrCpy $prevcond "checked"

   ${EndIf}

${Else}

   ${Unless} ${SectionIsSelected} ${sg1}

      !insertmacro UnSelectSection ${sg2}

      !insertmacro UnSelectSection ${sg3}

      StrCpy $prevcond "unchecked"

   ${EndIf}

${EndIf}

FunctionEnd

Add: Is this what you want?

Yes thank you very much

An older thread, but FWIW and for future reference in case someone else is looking for related information, here is a complete script ... (btw, the top two lines from the earlier snippet are not actually necessary)

var prevcond



SectionGroup /e "Group" SG

Section "SG1" sg1

   ${Unless} ${SectionIsSelected} ${sg1}

      ${If} ${SectionIsSelected} ${sg2}

      ${OrIf} ${SectionIsSelected} ${sg3}

         !insertmacro SelectSection ${sg1}

      ${EndIf}

   StrCpy $prevcond "checked"

   ${EndIf}

${Else}

   ${Unless} ${SectionIsSelected} ${sg1}

      !insertmacro UnSelectSection ${sg2}
