Change the installer size

Hi!

I've made an online installer using NSIS. I calculate what should be installed during the installation. However, when I select destination folder, the installation size is all wrong. I have the correct size in a variable - how do I change the installer size in the destination folder window?

Can I create a custom destination folder window?

I use code similar to this, which you might have to tweak in some places to make it work for you.

Var SRCDIR
Var SIZE
Section "InstallFiles" id1
  SetOutPath "-"
  File "${SRCDIR}\*.*"
SectionEnd
; False section
Section "New_Size" id2
SectionEnd
!define SetSize "Call SetSize"
Function SetSize
  StrCpy $SIZE "6474381" # ; size in bytes 
  ; bytes to kilobytes
  IntOp $0 $SIZE % 1024
  IntOp $SIZE $SIZE / 1024 ; rounded down
  IntCmp $0 512 0 +2 0
  IntOp $SIZE $SIZE + 1 ; rounded up
  SectionSetSize ${id1} 0 ; clear size estimate
  SectionSetSize ${id2} $SIZE ; reset the size
FunctionEnd
; Directory Page
Function DirectoryPageShow
  SectionGetSize ${id2} $2
  ; Required space (reset)
  ${if} $2 == 0
    ${SetSize}
  ${EndIf}
  SectionSetSize ${id2} $SIZE
FunctionEnd

Why not? The NSIS directory page is pretty good though.
