New Checkbox modifying components checkbox state
  Hello,

I hope my subject is clear.

Basicly, I want to be able to add a new checkbox to the Modern UI components page. To do this, I will go with the extract/write in ini files.

My main problem is that I want to be able to modify the state of the components checkbox (basicly gray/ungray them).

I saw a couple of threads about similar things but I can't seem to find a way to do it.

Here are the solutions I tought, yet none are imho nicely programmed:
- Use the checkbox as a *next* button. Use the MUI_PAGE_CUSTOMFUNCTION_LEAVE macro to call a function that will SetSectionFlags. Reload the page (can this be done?!)

- Use the checkbox as a *next* button. Create two components page, one with checkbox grayed and other one not grayed. Use the MUI_PAGE_CUSTOMFUNCTION_LEAVE to switch from one page to another. When the real next button is pressed, jump to Directory page.

Any ideas on this? If so, any references to examples/code/eetc...

The .OnSelChange callback might be useful,

So what have I done so far...Any tips would be welcomed..

Hacked the UI to add a checkbox control...to Dialog 104 (Components)

CONTROL "", 1044, BUTTON, BS_CHECKBOX | WS_CHILD | WS_VISIBLE, 0, 68, 90, 18 

>

  !define MUI_PAGE_CUSTOMFUNCTION_PRE Component_pre

 !define MUI_PAGE_CUSTOMFUNCTION_LEAVE Component_leave

 !insertmacro MUI_PAGE_COMPONENTS 

>

Component_pre

    FindWindow$0 "#32770" "" $HWNDPARENT

        GetDlgItem$1 $0 1044

    SendMessage$1 ${WM_SETTEXT} 0 "TESTING 123"



>FunctionEnd



>Function Component_leave

     #

     # Missing code to get the CheckBox Id (I know its reference to 1044 but how to get the event that called this function?

        ${If} ......

        ${if} $0 == "0"

            # default disable so no RO


           SectionGetFlags ${SECMatlab} $3

            IntOp$3 ${SF_SELECTED} | ${SF_RO}

           SectionSetFlags ${SECMatlab}  $3


            SectionGetFlags${SECDotNet} $3

            IntOp$3 $3 | ${SF_RO}

           SectionSetFlags ${SECDotNet}  $3


        ${else}

           SectionGetFlags ${SECMatlab} $3

            IntOp$3 $3 | ${SF_RO}

           SectionSetFlags ${SECMatlab}  $3


            SectionGetFlags${SECDotNet} $3

            IntOp$3 $3 | ${SF_RO}

           SectionSetFlags ${SECDotNet}  $3


        ${endif}

        abort

    ${EndIf}

Do check boxes send the BN_CLICKED notification? If so, you can use the ButtonEvent plug-in.

Everything worked perfectly with the ButtonEvent.

I still have a problem tought...

When in a section I put SectionIn RO, the components becomes greyed...

Yet with the code below it doesn't get grayed and the clear doesn't seem to work.

Component_Modification


  # Swap Values of Checkbox

 ${If} $DefaultCheckBox == 1 

      Strcpy $DefaultCheckBox "0"

  ${Else} 

     StrCpy $DefaultCheckBox "1"    

  ${EndIf}


  # Has user checked the check box ?

 FindWindow $R0 "#32770" "" $HWNDPARENT

  GetDlgItem $R1 $R0 1200

  

  SendMessage $R1${BM_SETCHECK} $DefaultCheckBox 0 



   ${If} $DefaultCheckBox != 1 # User has not checked check box.

          ; default disable so no RO and must turn grey


        SectionGetFlags${SECMatlab} $3

       !insertmacro ClearSectionFlag $3 ${SF_RO}

       SectionSetFlags ${SECMatlab}  $3


        SectionGetFlags${SECDotNet} $3

       !insertmacro ClearSectionFlag $3 ${SF_RO}

       SectionSetFlags ${SECDotNet}  $3

    ${else}

       SectionGetFlags ${SECMatlab} $3

        IntOp$3 $3 | ${SF_RO}

       SectionSetFlags ${SECMatlab}  $3


        SectionGetFlags${SECDotNet} $3

        IntOp$3 $3 | ${SF_RO}

       SectionSetFlags ${SECDotNet}  $3



    ${EndIf}

Is it possible to put the section checkbox to gray, I would need to send the BM_SETSTATE message.

If so, is there anyway to get access to the CheckBox from the section?
