[nsDialogs] How to create Checkbox with transparent background?
  Hello,
I am trying to write custom page using nsdialogs.
I am using bitmap control on the background. On that bitmap
I put some other controls, like labels and few checkboxes.
There are no problems with Label transparency, however I cant do the same with Checkbox (or RadioButton).
Is there any possibility to do that?

Here is a pseudocode I use:

Function CreateFinishPage


   Var /Global Finish_Dialog

   Var /GLOBAL Finish_Image

   Var /GLOBAL Finish_Image_Handle

    File/oname=$PLUGINSDIRFinish_Image.bmp "Graphics\\Wizard\\Welcome_Image.bmp"    

    

   Var /Global Finish_Header

   Var /Global Finish_Header_Font

   Var /Global Finish_Text    

   Var /Global Finish_Run



    

    LockWindow on

    GetDlgItem$0 $HWNDPARENT 3

    EnableWindow$0 0

    GetDlgItem$0 $HWNDPARENT 2

    EnableWindow$0 0    

    GetDlgItem $R0 $HWNDPARENT 1

    SendMessage $R0${WM_SETTEXT} 0 "STR:$(FINISH_QUIT)"    

   GetDlgItem $0 $HWNDPARENT 1028

    ShowWindow$0 ${SW_HIDE}

   GetDlgItem $0 $HWNDPARENT 1256

    ShowWindow$0 ${SW_HIDE}

   GetDlgItem $0 $HWNDPARENT 1045

    ShowWindow$0 ${SW_NORMAL}

    LockWindow off


    nsDialogs::Create /NOUNLOAD 1044

    Pop $Finish_Dialog

    

   ${If} $Finish_Dialog == error

        Abort

    ${EndIf}

    

;Header Text

   ${NSD_CreateLabel} 125u 15u 63% 30u "$(FINISH_TITLE)"

    Pop $Finish_Header

   ${NSD_AddStyle} $Finish_Header ${WS_VISIBLE}|${WS_CHILD}|${WS_CLIPSIBLINGS}

   CreateFont $Finish_Header_Font "TAHOMA" "12" "700"

   SendMessage $Finish_Header ${WM_SETFONT} $Finish_Header_Font 0    

    SetCtlColors $Finish_Header "0x000000" "TRANSPARENT"    

>; Text    

   ${NSD_CreateLabel} 130u 50u 185u 90u "$(FINISH_TEXT)"

    Pop $Finish_Text

   ${NSD_AddStyle} $Finish_Text ${WS_VISIBLE}|${WS_CHILD}|${WS_CLIPSIBLINGS}

   SetCtlColors $Finish_Text "0x000000" "TRANSPARENT"    


>; Run    

   ${NSD_CreateCheckBox} 125u 142u 60% 16u "Some text I use"

    Pop $Finish_Run    

    SetCtlColors $Finish_Run "0x000000" "TRANSPARENT"        


>; The checkbox is not transparent!


; Background Image    

   ${NSD_CreateBitmap} 0u 0u 100% 100% ""

    Pop $Finish_Image

   ${NSD_SetImage} $Finish_Image $PLUGINSDIRFinish_Image.bmp $Finish_Image_Handle

    


    nsDialogs::Show

   ${NSD_FreeImage} $Finish_Image_Handle    

    

FunctionEnd

I hope, someone of you can help. Thanks

One way would be to separate the text from the checkbox.

So your code would change like the following:

...

; Run    

   ${NSD_CreateCheckBox} 125u 145u 9u 9u ""

   Pop $0

   ${NSD_CreateLabel} 140u 145u 60% 16u "Some text I use"

    Pop $Finish_Run    

    SetCtlColors $Finish_Run "0x000000" "TRANSPARENT"

Yes, you are right. Thanks. I did that before. But, I want to learn how to do it normally (in that solution, I had to add .onclick functions for all labels, to simulate checkbox - more code, but works well). There must be some trick to do that.
I need some Windows API guru :p
Checkboxes, RadioButtons, GroupBoxes... I found this are not transparent.

I have solved this problem a long time ago.
Recently I was creating some nsDialogs page and I was not able to remember on it and I had to search in my old scripts...
So I put it on the forum now for everyone (also for me :D)

Var /Global CHECKBOX 

>${NSD_CreateCheckbox} 0 -50 100% 8u Test 

Pop $CHECKBOX 

># Set tranparent color for control 

>SetCtlColors $CHECKBOX "0xFF00FF" transparent 

># Add special style 

>${NSD_AddExStyle} $CHECKBOX ${WS_EX_TRANSPARENT}|${WS_EX_TOPMOST} 

Works fine for CheckBox and RadioButtons

On Windows XP, it works only fine for a push button if you had specified "XPStyle on", but doesn't support checkbox or radiobutton.

Actually it works ONLY for checkbox and radiobutton, because with labels there are no such problems...
I tried Win XP + Win 7 both were fine, also XPStyle on/off.

I just try your script again and I found that it works for a push-button and a radio button but not a checkbox. See my screenshot.

My customize checkbox:

This customize checkbox also draw a focus rectangle when either checkbox or label is clicked to imitate a real checkbox. But still has problem sometimes.

Using your script:

I also try to remove the line "${NSD_AddExStyle}", it is the same as before.

I am using official NSIS 2.46.

i have some checkbox and text controls on a tab, but only text control can use BackgroundTrans to make it looks good.
BackgroundTrans doesn't works on the text label of checkbox and radio.
anyone knows how to solve this?
thanks.
