Is there a way to do this? Using the API? I've been formatting the output with blanks to the left to push the data to the right but it would be much easier to just have the field be right-justified.

Hi,
Don't have a Mac, but mixing the Text and String Flags works for me on XP Pro.
That's why I posted to the Help Manual page.

Wow, thanks Shardik, you just made my day.

I really think this is a useful addition to the StringGadget.

I hope you don't mind if I add it to my 'API list for Mac' thread.

I have simplified my above example and expanded it to toggle between
left, center and right justification of the text:

Code: Select all

ImportC ""
  SetControlData(ControlRef.L, ControlPartCode.L, TagName.L, BufferSize.L, *Buffer)
  SetControlFontStyle(ControlRef.L, *ControlFontStyleRec)
EndImport

#kControlEditTextPart = 5
#kControlEditTextSelectionTag = 'sele'
#kControlUseJustMask = $40

Structure RGBColor
  Red.U
  Green.U
  Blue.U
EndStructure

Structure ControlFontStyleRec
  Flags.W
  Font.W
  Size.W
  Style.W
  Mode.W
  Just.W
  ForeColor.RGBColor
  BackColor.RGBColor
EndStructure

Structure ControlEditTextSelectionRec
  SelStart.W
  SelEnd.W
EndStructure

Define Style.ControlFontStyleRec
Define TextSelection.ControlEditTextSelectionRec

OpenWindow(0, 100, 100, 270, 130, "Justify text in StringGadget")
StringGadget(0, 5, 10, 260, 20, "1234567")
ButtonGadget(1, (WindowWidth(0) - 100) / 2, 40, 100, 20, "Justify right")
ButtonGadget(2, (WindowWidth(0) - 100) / 2, 70, 100, 20, "Justify left")
ButtonGadget(3, (WindowWidth(0) - 100) / 2, 100, 100, 20, "Justify center")

Repeat
  Select WaitWindowEvent()
    Case #PB_Event_CloseWindow
      Break
    Case #PB_Event_Gadget
      If EventType() = #PB_EventType_LeftClick
        GadgetID = EventGadget()

        If GadgetID >= 1 And GadgetID <= 3
          Style\Flags = #kControlUseJustMask
          Style\Just = GadgetID - 2

          ; ----- For right justification the cursor has to be positioned at the
          ;       right end because otherwise the text will be shifted out of view
          If GadgetID = 1
            TextSelection\SelStart = Len(GetGadgetText(0))
            TextSelection\SelEnd = TextSelection\SelStart
            SetControlData(GadgetID(0), #kControlEditTextPart, #kControlEditTextSelectionTag, SizeOf(ControlEditTextSelectionRec), @TextSelection)
            SetControlFontStyle(GadgetID(0), @Style)
          EndIf

          SetControlFontStyle(GadgetID(0), @Style)
        EndIf
      EndIf
  EndSelect
