Hidden Section gets "deselected"
Hi everyone,

i have a hidden section,


Section -FirstToExecute SEC_FIRSTTOEXECUTE
SectionEnd


and a couple more sections (one more hidden, about 20 or so regular).

Now in some cases that section does not get executed, i could narrow it down to this happening when i change something in the component selection (select an additional section). The Setup can be used to install (previously not installed) components when called a second time, to accomodate this i use a macro that i have "derived" from the "SELECT_UNSECTION" macro from the examples.


!macro DISABLE_SECTION SECTION_NAME SECTION_ID
    Push $R0
    ReadRegStr $R0 HKLM "${REGKEY}\Components" "${SECTION_NAME}"
    StrCmp $R0 1 0 next${SECTION_ID}
    !insertmacro SetSectionFlag "${SECTION_ID}" ${SF_RO}
        !insertmacro ClearSectionFlag "${SECTION_ID}" ${SF_SELECTED}
next${SECTION_ID}:
    Pop $R0
!macroend


That macro is called from

!define MUI_PAGE_CUSTOMFUNCTION_PRE "PRE_PAGE_COMPONENTS"





Function PRE_PAGE_COMPONENTS

        !insertmacro DISABLE_SECTION "Business Logic (required)" ${SEC_FRAMEWORK}
        !insertmacro DISABLE_SECTION "Backup Server" ${SEC_BACKUPSERVER}
        !insertmacro DISABLE_SECTION "Deployment Service" ${SEC_DEPLOYMENTSERVICE}
.
.
.
FunctionEnd


I put

Function .onSelChange
        
SectionGetFlags ${SEC_FIRSTTOEXECUTE} $0
IntOp $0 $0 | ${SF_SELECTED}
SectionSetFlags ${SEC_FIRSTTOEXECUTE} $0
        
!insertmacro StartRadioButtons $1
!insertmacro RadioButton ${SEC_FIREBIRDSERVER2}
!insertmacro RadioButton ${SEC_FIREBIRDSERVER264}
!insertmacro EndRadioButtons
FunctionEnd

in (the code is an example from the manual) but it does not help, the section is not executed.

I checked if i accidentally "uncheck" the section "SEC_FIRSTTOEXECUTE" but i don't, i also do not loop through the sections to do anything to them (i have seen you can do that).

Any ideas?

Your help is much appreciated.
Thanks.

Well the problem seems to be the RadioButton macros in .onSelChange, if i remark that block everything works wonderful. I have looked at the macros in section.nsh but i have no clue why it would behave like that.



!insertmacro StartRadioButtons $1
!insertmacro RadioButton ${SEC_FIREBIRDSERVER2}
!insertmacro RadioButton ${SEC_FIREBIRDSERVER264}
!insertmacro EndRadioButtons

*sigh*

i also tried changing the variables in the "keep always selected" part of .onSelChange so it looks like this:


SectionGetFlags ${SEC_FIRSTTOEXECUTE} $R9
IntOp $R9 $R9 | ${SF_SELECTED}
SectionSetFlags ${SEC_FIRSTTOEXECUTE} $R9


but no :(

For unselecting a selected section you can use:

SectionGetFlags ${SectionIndex} $R0
IntOp $R0 $R0 & ${SECTION_OFF}
SectionSetFlags ${SectionIndex} $R0


For selecting a unselected section the code is: 
SectionGetFlags ${SectionIndex} $R0
IntOp $R0 $R0 ^ ${SF_SELECTED}
SectionSetFlags ${SectionIndex} $R0


I hope it helps you.

Actually for selecting any section (selected or unselected) use:

SectionGetFlags ${SectionIndex} $R0
IntOp $R0 $R0 | ${SF_SELECTED}
SectionSetFlags ${SectionIndex} $R0
For unselecting any section use: 
SectionGetFlags ${SectionIndex} $R0
Intop $R1 ${SF_SELECTED} ~
IntOp $R0 $R0 & $R1
SectionSetFlags ${SectionIndex} $R0
To toggle any section use: 
SectionGetFlags ${SectionIndex} $R0
IntOp $R0 $R0 ^ ${SF_SELECTED}
SectionSetFlags ${SectionIndex} $R0

jpderuiter:

your example for selecting a section (selected or unselected) is what i need, and its what i got from the manuals, but it doesn't work reliable for me :(

Is there another way to get that "RadioButton" functionality into the components tree, without using the macros?

Hi xbarns,

I just wanted to correct the post from ChocJunkie.

I don't know another method, as far as I can see you are doing nothing wrong.
Strange that even forcing the selected state in .OnSelChange does not work.
Can you check if that peace of code is actually called (with a messagebox or something)?

Hi jpderuiter,

oh :)

I did the Messagebox thingy already it is called :(

Are you sure you're not using $1 anywhere else? If you are, change the radiobuttons variable to something you don't use.

MSG,

well $1 is used quite frequently during that setup (its a rather large setup).

But i have already tried setting a unique variable for this, same result sadly....

Btw. i am using the unicode (2.45) Version of NSIS (i forgot to mention this earlier).
