The Case of the Disappearing List Box

Recommended Posts

Please have a look at the code below. :">

The right list box is being deleted and populated correctly until...the about dialog box is pulled up and closed. Now the right list box just disappears! :idiot:

#include <GUIConstants.au3> ; Must include for GUI functions to work

$parentgui = GUICreate ("Main", 280, 105) ; will create the main program window
$helpmenu = GUICtrlCreateMenu ("&Help")
$aboutitem = GUICtrlCreateMenuitem ("&About",$helpmenu)
GUISetState () ; will display the main program window

Global $List1 = GUICtrlCreateList ("", 10, 15, 120, 80)
GUICtrlSetData ($List1, "item1|item2|item3")
Global $leftlist = GUICtrlRead ($List1)
Global $List2 = GUICtrlCreateList ("", 150, 15, 120, 80)

; Run the GUI until the dialog is closed
While 1
  $msg = GUIGetMsg (1)
  $ctrlmsg = $msg[0]
  $win = $msg[1]
  $_leftlist = GUICtrlRead ($List1)

  Select

    Case $ctrlmsg = $GUI_EVENT_CLOSE AND $win = $parentgui
      ExitLoop

    Case $ctrlmsg = $GUI_EVENT_CLOSE AND $win = $childgui
      GUISwitch ($parentgui)
      GUISetState (@SW_ENABLE)
      GUISwitch ($childgui)
      GUISetState (@SW_HIDE)

    Case $ctrlmsg = $aboutitem
      $winpos = WinGetPos ("Main")
      $childgui = GUICreate ("About", 260, 85, $winpos[0] + 10, $winpos[1] + 10, BitOr ($WS_POPUP, $WS_CAPTION, $WS_SYSMENU), -1, $parentgui)
      GUISetState (@SW_SHOW)
      GUICtrlCreateLabel ("Program Version 0.1.0" & chr(10) & chr(10) & "Copyright " & chr(169) & " 2005 Inc.", 62, 10, 150, 75, $SS_CENTER)
      GUISetState (@SW_ENABLE)
      GUISwitch ($parentgui)
      GUISetState (@SW_DISABLE)

    Case $leftlist <> $_leftlist
      $leftlist = GUICtrlRead ($List1)
      GUICtrlDelete ($List2)
      Global $List2 = GUICtrlCreateList ("", 150, 15, 120, 80)
      If $leftlist = "item1" Then GUICtrlSetData ($List2, "item10|item11|item13")
      If $leftlist = "item2" Then GUICtrlSetData ($List2, "item20|item21|item23")
      If $leftlist = "item3" Then GUICtrlSetData ($List2, "item30|item31|item33")

  EndSelect
Wend

Check the slight changes...really the script had two unnecessary lines.

(Check the comments in "Case $leftlist <> $_leftlist" block)

That's it! Oh man do I feel silly on one hand and slap happy on the other.
