Sections greyed out
MOre questions....

I am getting the hang of NSIS stuff now well maybe. :)

OK sections.

I understand a bit of teh section stuff but I cannot make it do what I want.

I want to grey out boxes and have hem set to unticked.

Most greyed out check boxes are for required components but I wanrt it to be grey out and unticked. It is preverse settings if the program is already installed. If the app has not been installed then I do not want the check box to be enabled.

Is this possible with NSIS?

Sure. It involves some "bit banging" and program logic on your part.

Have a look at the doco file "NSIS/Examples/one-section.nsi".

Also have a look at the functions SectionGetFlags/SectionSetFlags

Set the section's style to SF_RO alone (no SF_SELECTED). To do this, you'll need SectionSetFlags as djc said. The exact code is:

SectionSetFlags${section}${SF_RO}

so... what's the flag for autoselect the section but still, we
can uncheck it.... I try ALL the flags, but the autoselect
(Read only), can't be uncheck... :(

Give it only SF_RO and no SF_SELECTED and it will be RO but not selected.

Thanks for the help folks but I am still none the wiser. :( I had already seen the set flags things.

I have only had chance to look at this recently.

now how does this work......

I have the simplest script I can think of and it still does not work. No checking nothing just the section options for the one example. It stil does not work. :(


I presume that a line like
SectionSetFlags "sec4" $SF_RO

should be put in the relevant section?? WEll if I put it outside teh section it does not compile (it equates SF_RO though). :(

But in the section it cannot equate what the constant/variable SF_RO is (WTF that doesn't make sense at all....:confused: ) so for this example I have used the actual decimal values. But nothing. :( It appears both selected AND not greyed out AND you can toggle it......

Am I doing something stupidly wrong or what?

The script.

Name example
OutFile one-section.exe

ComponentText "please choose just one but the default"

!define SF_SELECTED 1
!define SF_SUBSEC 2
!define SF_SUBSECEND 4
!define SF_BOLD 8
!define SF_RO 16
!define SF_EXPAND 32

!define SECTION_OFF 0xFFFFFFFE

Section !Required
SectionIn RO
SectionEnd

;SectionSetFlags sec4 SF_RO

Section "optional #1" sec1
SectionEnd

Section "optional #2" sec2
SectionEnd

Section "optional #3" sec3
SectionEnd

Section "optional #4" sec4
;SectionSetFlags "sec4" $SF_RO
SectionSetFlags "sec4" 16
SectionEnd

;SectionSetFlags "sec4" $SF_RO

any ideas..

Thanks folks.
