blanking out the Install button
how do i blank out the install button. i want it to appear, just faded out, and the user can't click on it until they select at least one component on MUI_PAGE_COMPONENTS

is there a code that I can use to set the install button temporarily off, then when the user clicks on one of the components (each component is in a different section)it will become active.

Thanks.

Disable/enable it with EnableWindow.

ok , i tried the following code and it removed the next button on the welcome page...

!define MUI_WELCOMEFINISHPAGE_CUSTOMFUNCTION_INIT disableInstallButton

Function disableInstallButton
GetDlgItem $1 $HWNDPARENT 1
EnableWindow $1 0
FunctionEnd

but now i want it to do the same thing, only on the components page, and this time the install button.
I have a bunch of sections on the components page.
How do I get this code to work on the MUI_PAGE_COMPONENTS?

Replace MUI_WELCOMEFINISHPAGE_CUSTOMFUNCTION_INIT with MUI_PAGE_CUSTOMFUNCTION_SHOW and place the entire line (!define ...) before !insertmacro MUI_PAGE_COMPONENTS.

As for enabling/disabling the button dynamically on section check/uncheck, you need to do this in .onSelChange and use ${If} ${SectionIsSelected} (LogicLib.nsh).

ok replacing the line and placing it before MUI_PAGE_COMPONENTS worked successfully!
The Install option is now blanked out.

The next problem is this...

I have included LogicLib at the top of my script as
!include LogicLib.nsh

However, when I add the following code to .onSelChange, which is located at the very bottom of my script, i get a compiler error message

Function .onSelChange
${If} ${SectionIsSelected}
GetDlgItem $1 $HWNDPARENT 1
EnableWindow $1 1
FunctionEnd

The error message is

!insertmacro: macro "_If" requires 4 parameter(s), passed 3!
Error in script "G:\setup.nsi" on line 398 -- aborting creation process


If I take out the code
${If} ${SectionIsSelected}
the install button appears from its blanked out state when the user clicks on a component. However, it does not return to the blanked out state when they unclick it.

Any suggestions?

${SectionIsSelected} requires a section index (the identifier you add after the section name). And you are missing the ${EndIf}. You probably want an ${Else} to reset (disable) the button when the section is not selected.

Function .onSelChange
GetDlgItem $1 $HWNDPARENT 1
${If} ${SectionIsSelected} ${mySectionId}
  EnableWindow $1 1
${Else}
  EnableWindow $1 0
${EndIf}
FunctionEnd

Make sure this function goes after all sections.

I.e.

Section "A section" mySection1
SectionEnd

Section "Another section" mySection2
SectionEnd

Function .onSelChange
GetDlgItem $1 $HWNDPARENT 1
${If} ${SectionIsSelected} ${mySection1}
${OrIf} ${SectionIsSelected} ${mySection1}
  EnableWindow $1 1
${Else}
  EnableWindow $1 0
${EndIf}
FunctionEnd
