how to disable custompage, when section selected
  Hey all,
I can't find a solution for my problem:
I want to show custompage conditionally (only when section is selected). At the moment my custompage appears always, no mather if section is selected or not. here is my simplified script:
(original script contains more than 1000 lines, several sections and a lot of functions)

!include "MUI.nsh"
Name "Test"
OutFile "text.exe"
InstallDir "$PROGRAMFILES\Test"

!insertmacro MUI_PAGE_COMPONENTS
Page custom CustomPage
!insertmacro MUI_PAGE_DIRECTORY
!insertmacro MUI_PAGE_INSTFILES

ReserveFile "CustomPFile.ini"
!insertmacro MUI_RESERVEFILE_INSTALLOPTIONS

Section "Section" SecIndex
SetOutPath "$INSTDIR"
WriteRegStr HKCU "Software\Modern UI Test" "" $INSTDIR
WriteUninstaller "$INSTDIR\Uninstall.exe"
SectionEnd

Function .onInit
!insertmacro MUI_INSTALLOPTIONS_EXTRACT "CustomPFile.ini"
FunctionEnd

Function CustomPage
!insertmacro MUI_INSTALLOPTIONS_DISPLAY "CustomPFile.ini"
FunctionEnd

I would be very greatful, if someone could tell me how to make custompage disappear when section is not selected

i used this :

Function YourName

 SectionGetFlags${YourSection} $0

 StrCmp$0 ${SF_SELECTED} 0 skipPage

 !insertmacro MUI_HEADER_TEXT "bla" "bla bla"

 !insertmacro MUI_INSTALLOPTIONS_DISPLAY "YourINIfile.ini"

>skipPage:

>FunctionEnd

big tnx to o_owd,
I got it now working by, editing the code a little.
The replacement(wich o_owd advised didn't work (0 -> 1), It could be +1 or label(i like it more):
StrCmp $0 ${SF_SELECTED} showpage skipPage

And then i had to !include Sections.nsh to get whole thing working.
I attach my script..Hopefully it helps someone. To get this script working you have to rename some custompage ini file(for example from nsis examples dir) to CustomPFile.ini

it doesn't work, as i thought frist place! :eek:
now that i have tested it with more than one section it seems that it considers only the section, that is the first on the list, not the one, that i have selected with SectionGetFlags. i really need some help. can someone please look and correct my script(this one has 3 sections) :confused:

sorry for that! my mistake. :down:

replace

SectionGetFlags Sec2Index $0

StrCmp$0 ${SF_SELECTED} showpage skipPage

 showpage:

  !insertmacro MUI_HEADER_TEXT "bla" "bla bla"

 !insertmacro MUI_INSTALLOPTIONS_DISPLAY "CustomPFile.ini"

>skipPage: 

SectionGetFlags${Sec2Index} $0

StrCmp$0 "0" 0 skipPage

 !insertmacro MUI_HEADER_TEXT "bla" "bla bla"

 !insertmacro MUI_INSTALLOPTIONS_DISPLAY "CustomPFile.ini"

ok, now i got it working, almost as i wanted. It works great with usual sections, but still don't know how to make it working with subsections. by the way there was still one little mistake in last post:

change this:
SectionGetFlags ${Sec2Index} $0
StrCmp $0 "0" 0 skipPage #shows if not selected
!insertmacro MUI_HEADER_TEXT "bla" "bla bla"
!insertmacro MUI_INSTALLOPTIONS_DISPLAY "CustomPFile.ini"
skipPage:

with:

SectionGetFlags ${Sec2Index} $0
StrCmp $0 "0" 1 skipPage # shows if selected
!insertmacro MUI_HEADER_TEXT "bla" "bla bla"
!insertmacro MUI_INSTALLOPTIONS_DISPLAY "CustomPFile.ini"
skipPage:

my dear.
u didn't read the docs about section-flags.
the command SectionGetFlags return ALL flags as 32bit integer. means, that if the section has more than one flag set (like subsections have, or bold sections, see the docs), the number is different.
this code will extract the needed flag:

!macro  GetSectionSelection  SECTION
        Push    $1
        SectionGetFlags "${SECTION}"  $1
        IntOp   $1  $1 & 1
        Exch            $1
!macroend

!insertmacro GetSectionSelection ${mysection}
Pop $0
StrCmp $0 1 selected not_selected
selected:
not_selected:
