Edit control losing data

5 posts in this topic

The following script has 2 edits. there are 2 variables which are set to equalk the 2 edits. If I switch the variables to point to the other edits then the first text which is added to th eedit replaces the previous text. I don'yt understand this so maybe someone can either point out what I should be seeing but can't or tell me they think the behaviour is wrong.

#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <guiedit.au3>

#region ### START Koda GUI section ### Form=
$Form2 = GUICreate("Form2", 613, 298, 302, 218)
$Edit1 = GUICtrlCreateEdit("", 119, 46, 185, 204)
GUICtrlSetData(-1, "Edit1")
$Edit2 = GUICtrlCreateEdit("", 318, 46, 185, 204)
GUICtrlSetData(-1, "Edit2")

             ConsoleWrite(GUICtrlRead($EdA) & @CRLF);this shows the data correctly

Hello Martin

It looks like an issue with GUICtrlSetState(), when it is used with $GUI_HIDE on an edit control.

If you disable and hide the edit, it solves this problem.

Report to Trac?

GUICtrlSetState($Edj, $GUI_ENABLE+$GUI_SHOW)

GUICtrlSetState($Edk, $GUI_DISABLE+$GUI_HIDE)

Hi Rover,

Thanks for that.

I'll play with your finding and then I'll post a bug report.

EDIT:

Rover, although you're right that adding $GUI_DISABLE fixes the problem, I can't make a simple repoducer to show that hiding the edit can make it loose data. The code below works as expected.

[
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <guiedit.au3>
opt("GUIONEVENTMODE",1)
#region ### START Koda GUI section ### Form=
$Form2 = GUICreate("Form2", 443, 298, 302, 218)
$Edit1 = GUICtrlCreateEdit("", 119, 46, 185, 204)
GUICtrlSetData(-1, "Edit1")
$BtnAdd = GUICtrlCreateButton("add line to edit", 10, 100)
GUICtrlSetOnEvent(-1,"BtnAddClick")
$BtnHide_Show = GUICtrlCreateButton("Hide/Show edit", 10, 150)
GUICtrlSetOnEvent(-1,"BtnHideShowClick")
GUISetState(@SW_SHOW)
GUISetOnEvent($GUI_EVENT_CLOSE,"Finished")
#endregion ### END Koda GUI section ###
;GUICtrlSetState($Edit2, $GUI_HIDE)

$Show = $GUI_SHOW
$count = 1
While 1


    Sleep(100)
WEnd

func finished()
    Exit
EndFunc

func BtnAddClick()
     GUICtrlSetData($Edit1, "---> " & $count & @CRLF, "1")
            $count += 1
EndFunc

func BtnHideShowClick()
     $Show = $GUI_HIDE + $GUI_SHOW - $Show;toggle
            GUICtrlSetState($Edit1, $Show)

EndFunc

Any suggestions?

You need two edit controls to get this result.

The problem only occurs if the first edit control created is hidden, as in your _SwitchSeens() function,

then the second edit control has text appended.

Any other combination of edit controls appends normally.

only the edit1-hidden, edit2-append arrangement has this result.

Once edit1 is hidden, additional text appends normally to edit2

The reproducer shows that if edit 1 is re-shown, then re-hidden,

edit 2's text will still be cleared when a line is appended.

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
Opt("MustDeclareVars", 1)

Local $add = True, $s
GUICreate("Form2", 400, 298, 302, 218)
Local $Edit1 = GUICtrlCreateEdit("Edit1", 10, 46, 120, 204)
Local $Edit2 = GUICtrlCreateEdit("Edit2", 140, 46, 120, 204)
;Local $Edit3 = GUICtrlCreateEdit("Edit3", 270, 46, 120, 204)
GUISetState(@SW_SHOW)

For $i = 0 To 6
    $s &= "------------> " & $i & @CRLF
Next

While GUIGetMsg() <> -3
    If $add Then
        GUICtrlSetData($Edit2, $s, "1")
        Sleep(2000)
        GUICtrlSetState($Edit1, $GUI_HIDE);text cleared from edit 2, when line appended
        ;GUICtrlSetState($Edit1, $GUI_HIDE+$GUI_DISABLE) ; text appended to edit 2
        GUICtrlSetData($Edit2, "------------> 6" & @CRLF, "1")

        Sleep(2000)
        GUICtrlSetData($Edit2, "")
        GUICtrlSetState($Edit1, $GUI_SHOW)
        GUICtrlSetData($Edit2, $s, "1")
        Sleep(2000)
        GUICtrlSetState($Edit1, $GUI_HIDE);text cleared from edit 2, when line appended
        ;GUICtrlSetState($Edit1, $GUI_HIDE+$GUI_DISABLE) ; text appended to edit 2
        GUICtrlSetData($Edit2, "------------> 6" & @CRLF, "1")
        $add = False
    EndIf
WEnd
Exit

Rover,

you have a line

GUICtrlSetData($Edit2, "")

which removes the text so that shouldn't be there.

I think the bug is to do with the selected text in Edit2 being changed by hiding and showing Edit1. If you use _GUICtrlEdit_AppendText then there is no problem.

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <guiedit.au3>

Opt("MustDeclareVars", 1)

Local $add = True, $s
GUICreate("Form2", 400, 298, 302, 218)
Local $Edit1 = GUICtrlCreateEdit("Edit1", 10, 46, 120, 204)
Local $Edit2 = GUICtrlCreateEdit("Edit2", 140, 46, 120, 204)
GUISetState(@SW_SHOW)

For $i = 0 To 6
    $s &= "------------> " & $i & @CRLF
Next

While GUIGetMsg() <> -3
    If $add Then
        GUICtrlSetData($Edit2, $s, "1")
        Sleep(2000)
        GUICtrlSetState($Edit1, $GUI_HIDE);text cleared from edit 2, when line appended
        ;GUICtrlSetData($Edit2, "------------> 6 <--should be a duplicate number" & @CRLF, "1")
        _GUICtrlEdit_AppendText($Edit2, "---another--> 6" & @CRLF)
        Sleep(2000)
        ; GUICtrlSetData($Edit2, "")
        GUICtrlSetState($Edit1, $GUI_SHOW)
        GUICtrlSetData($Edit2, $s, "1 ")
        Sleep(2000)
        GUICtrlSetState($Edit1, $GUI_HIDE);text cleared from edit 2, when line appended
        ;GUICtrlSetData($Edit2, "------------> 6" & @CRLF, "1")
        _GUICtrlEdit_AppendText($Edit2, "-------------> end??")
        Sleep(2000)
        GUICtrlSetState($Edit1, $GUI_SHOW)
        $add = False
    EndIf
    ;#ce
WEnd

Anyway, it is incorrect behaviour so I'll report it as a bug

EDIT: trac ref #1924
