How to pop up a page if a section in component page is selected?

[tmxk]

Hi all,

I am new to NSIS.
Can anybody tell me how to pop up a page if a section in component page is selected? This page should not show up in the main script, otherwise it always pops up no mater the related section is selected or not.
Thanks in advance.

You can see the example "makensis.nsi"

[Red Wine]

code:
outfile test.exe

ShowInstDetails show

InstallDir "$PROGRAMFILES\My Application"



!include logiclib.nsh



page components

page directory pre_func

page instfiles



Section "Main Application" sec1

       detailprint "installing Main pplication"

SectionEnd



Section /o "!When checked enables the directory page" sec2

       detailprint "Installing..."

Sectionend



Function pre_func

      SectionGetFlags ${sec2} $R0

      Intop $R1 $R0 | 1

      ${Unless} $R0 = $R1

           Abort

      ${EndUnless}

FunctionEnd

Hi, can I have another question?

I have a custom page on which there are 2 Radiobuttons, after the selection of the 2 Radiobuttons, a component page shows up, some of the sections will be disabled or enabled based on the Radiobutton selection. How can I set the sections?
From my understanding, there is one way, such as "SectionIn RO", but it is only for compile time but runtime.
And there is another way to do it for runtime, "SetSectionFlag ${SEC_NAM} ${SF_RO}", but I tried to set it either in RadioButton page function (PageLeave) or in the relative section.
Can you experts help?
Thanks in advance.

2 examples, first is to keep sections in tact when back button is pressed and second simply disables back button.

code:
!define CUST_INI "$PLUGINSDIR\custom.ini"

!include Logiclib.nsh

!include Sections.nsh



!define SEC1_TEXT "Section One"

!define SEC2_TEXT "Section Two"

!define SEC3_TEXT "Section Three"



outfile "test.exe"

showinstdetails show

Installdir "$PROGRAMFILES\My App"



page custom CreateCustom

page components func_pre

page directory

page instfiles



section "${SEC1_TEXT}" sec1

detailprint "section 1 selected"

sectionend



section "${SEC2_TEXT}" sec2

detailprint "section 2 selected"

sectionend



section "${SEC3_TEXT}" sec3

detailprint "section 3 selected"

sectionend
