Expanding text field ... is there such a thing?

20 posts in this topic

I have a special situation where a text field is normally only one line.  But every now and then, it needs to hold several lines ... up to a couple of paragraphs.

Is there such a thing as an expanding text field? — one that can expand downward as additional lines are typed in?  (see attached)

I see this kind of thing all the time in programmed applications.  But I can't spot any reference or example for AutoIt3.  Here's the code for my simple example:

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

Local $hGui, $hRichEdit, $iMsg
$hGui = GUICreate("Example ", 320, 320, -1, -1)
$hRichEdit = _GUICtrlRichEdit_Create($hGui, "This is the first field.", 10, 10, 300, 20, $ES_MULTILINE)
GUISetState()

While True
    $iMsg = GUIGetMsg()
    Select
        Case $iMsg = $GUI_EVENT_CLOSE
             _GUICtrlRichEdit_Destroy($hRichEdit)
             Exit
    EndSelect
WEnd

Thanks in advance for any pointers on a direction to take with this.

qwert,

Or you can do it like this: :)

#include <GUIConstantsEx.au3>
#include <GuiRichEdit.au3>

$hGUI = GUICreate("Test", 500, 500)

$hRichEdit = _GUICtrlRichEdit_Create($hGUI, "This is the first field.", 10, 10, 300, 20, $ES_MULTILINE)

GUISetState()

Global $iCurrCount = _GUICtrlRichEdit_GetLineCount($hRichEdit)

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch

    If _GUICtrlRichEdit_IsModified($hRichEdit) Then
        _CheckRichEditLineCount()
    EndIf


WEnd

Func _CheckRichEditLineCount()

    Local $iCount = _GUICtrlRichEdit_GetLineCount($hRichEdit)
    If $iCount <> $iCurrCount Then
        WinMove($hRichEdit, "", Default, Default, Default, 7 + ($iCount * 13))
        $iCurrCount = $iCount
    EndIf
    _GUICtrlRichEdit_SetModified($hRichEdit, False)

EndFunc   ;==>_CheckRichEditLineCount
I derived the values for thw new height empirically - no doubt you could determine them programatically if required. ;)

Melba, thanks you for your suggestion.  It does accomplish what I requested ... and in a forthright way.

However, I spent the morning running ALL the examples of your StringSize, GUIExtender and GUIFrame UDFs.  Very impressive work!

Now I see that there are many more possibilities ... which has led me to consider an even better implementation.  (See prototype, below.)

Do you have a suggestion on how to make a field expand only if it is selected?

My initial impression is that I could do it with the GUIExtender features, but that the result would be a shift effect, not an overlay effect.

qwert,

More complex than I thought it would be. And how do you intend selecting a RichEdit which becomes hidden under one which has extended? :huh:

Yes, I didn't mention that.  My idea is that a field would expand only when it was selected ... and then revert to a one-line field when any other field (or no field) was selected.  It would behave about like a drop-down selection for state or country ... but it would allow key entry.

qwert,

I have run into 2 problems:

 

- 1. Lower RichEdit controls appear through the expanded one.

- 2. These "hidden" edit controls cannot be reselected.

#include <GUIConstantsEx.au3>
#include <GuiRichEdit.au3>
#include <WinAPI.au3>

Global $aRichEdit[4][2] = [[0, 1], [0, 1], [0, 1], [0, 1]]
Global $hLast_Focus = 9999

$hGUI = GUICreate("Test", 500, 500)

$aRichEdit[0][0] = _GUICtrlRichEdit_Create($hGUI, "This is the first field.", 10, 10, 300, 20, $ES_MULTILINE)
$aRichEdit[1][0] = _GUICtrlRichEdit_Create($hGUI, "This is the second field.", 10, 40, 300, 20, $ES_MULTILINE)
$aRichEdit[2][0] = _GUICtrlRichEdit_Create($hGUI, "This is the third field.", 10, 70, 300, 20, $ES_MULTILINE)
$aRichEdit[3][0] = _GUICtrlRichEdit_Create($hGUI, "This is the fourth field.", 10, 100, 300, 20, $ES_MULTILINE)

$cButton = GUICtrlCreateButton("Test", 10, 300, 80, 30)

GUISetState()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch

    $hCurr_Focus = _WinAPI_GetFocus()
    For $i = 0 To 3
        If $hCurr_Focus = $aRichEdit[$i][0] Then
            _CheckRichEditLineCount($i)
            ExitLoop
        EndIf
    Next
    ; If none focused
    If $i = 4 And $hCurr_Focus <> $hLast_Focus Then
        ConsoleWrite("Resetting Last" & @CRLF)
        ; Reset last focused control
        WinMove($hLast_Focus, "", Default, Default, Default, 20)
        $hCurr_Focus = $hLast_Focus
    EndIf

WEnd

Func _CheckRichEditLineCount($iIndex)

    ; Reset last focused control if not the same
    If $hLast_Focus <> $aRichEdit[$iIndex][0] Then
        ConsoleWrite("Resetting " & $iIndex & @CRLF)
        WinMove($hLast_Focus, "", Default, Default, Default, 20)
        $hLast_Focus = $aRichEdit[$iIndex][0]
    EndIf

    ; Get count of current
    Local $iCount = _GUICtrlRichEdit_GetLineCount($aRichEdit[$iIndex][0])
    If $iCount <> $aRichEdit[$iIndex][1] Then
        WinMove($aRichEdit[$iIndex][0], "", Default, Default, Default, 7 + ($iCount * 13))
        $aRichEdit[$iIndex][1] = $iCount
    EndIf

EndFunc   ;==>_CheckRichEditLineCount
The second problem could be worked around by having buttons to the side of the edit controls to help select them, but the first is giving me a bit of a headache at present. :(

Edit: I have found a solution - now to get it to work elegantly! :D

Melba23, THAT is an outstanding solution.  It exceeds what I had hoped for:

►The fields are limited in total length so they are confined to an area of the GUI.

►The fields convert to a scrollable field only when content size is too large per above.

►The fields accept drag/drop text.

►The number of fields is specified by a single parameter.

As icing on the cake, I added a button/area of the screen to deselect ... which works great.  Here's a screen shot of my result so far.

You have made my day.  Thanks very much.

@Melba23:  I do have one additional question.  I'm trying to increase the font size to 14.  You identified the major parameters from the start:

Global $iEdit_Count = 4         ; Number of edits
Global $iEdit_Height = 20       ; Initial height of edits
Global $iEdit_Separation = 40   ; Distance from one edit to next
Global $iEdit_MaxDrop = 300     ; Max Y coord for expansion

But in the _CheckRichEditLineCount function you use a constant of 7.  I've tried different values to correspond to a font size of 14, but I can't get the sizing to behave.  (The size of a field doesn't increase properly as entries are made.)

Would you mind pointing out which lines need to change for a font increase from 8.5 to 14?

qwert,

As I explained in my first post in the thread, I derived the values to use when expanding the edit controls empirically - better known as "trial and error". ;)

If I find the time I will see if I can find a way to determine the correct values programatically later today. :)

M23

Edit: A question. You are using RichEdit controls, I presume so various font sizes can be used in each control. If you do use different fonts withint he same control any expansion will fail because there is no easy way of telling the height of each line. Do you really need RichEdit controls or would plain old Edit controls do instead? :huh:

Do you really need RichEdit controls or would plain old Edit controls do instead?

The fields will have a default font that will serve for all text entry cases.  But for certain fields, I'd like to be able to accept rich text from some other source, like text from a browser window.  In those few instances, however, it would certainly be acceptable for the default font rules to apply.  The field just wouldn't behave quiet as well, but for good reason.

Does that help?

qwert,

I have spent a most frustrating day trying to develop an algorithm to get the edits to expand nicely regardless of the font size. Alas so far I have come up empty handed, so annoyingly I may have to fall back on empirically-derived values for a 14pt font. :(

I will keep at it for a while and let you know if I manage to get anything resolved. :)

Sorry to hear that.

Would a simplifying assumption help?:  If any non-default text is detected, open the field at its maximum size.

I have used your assumption for when non-standard font sizes are detected. :)

I think it's a very workable solution.  The only hitch is that typing an entry now has a strange effect on the initial line or two.  It tries to shift gears between a having a vertical scroll bar or not.  For three lines and more, it works just like before.

qwert,

I have slightly modified the sizing code - for me this is pretty good: :)

Func _CheckRichEditLineCount($iIndex, $fReset = False)

    Local $iEdit_Depth = 0, $iEdit_Bottom

    ; Get current style
    Local $iCurr_Style   = _WinAPI_GetWindowLong($aRichEdit[$iIndex][0], $GWL_STYLE)

    Local $aEdit_Font = _GUICtrlRichEdit_GetFont($aRichEdit[$iIndex][0])
    ; Check if all same font
    If $aEdit_Font[0] = 0 Then
        ; Not all the same size so max edit immediately
        WinMove($aRichEdit[$iIndex][0], "", Default, Default, Default, $aRichEdit[$i][2])
        _Check_Visible($iIndex, $aRichEdit[$i][2])
    Else
        ; Get line count of current edit
        Local $iCount = _GUICtrlRichEdit_GetLineCount($aRichEdit[$iIndex][0])
        If $iCount <> $aRichEdit[$iIndex][1] Or $fReset = True Then
            ; Calulate required size
            $iEdit_Depth = (($iFont_Size * 2) + 1) + (($iFont_Size * 2) - 2) * ($iCount - 1)
            If $iEdit_Depth > $aRichEdit[$i][2] Then
                If Not $aRichEdit[$iIndex][3] Then
                    $aRichEdit[$iIndex][3] = (($iFont_Size * 2) + 1) + (($iFont_Size * 2) - 2) * ($iCount - 2)
                EndIf
                $iEdit_Depth = $aRichEdit[$iIndex][3]
            EndIf
            ; Resize edit
            WinMove($aRichEdit[$iIndex][0], "", Default, Default, Default, $iEdit_Depth)
            ; Save line count
            $aRichEdit[$iIndex][1] = $iCount
            _Check_Visible($iIndex, $iEdit_Depth)
        EndIf
    EndIf

EndFunc   ;==>_CheckRichEditLineCount
There is still a flash of scrollbar but that is to be expected as the resizing takes a short time to be applied and until then the edit thinks it needs a scroll bar. ;)

And I think that is it as far as I am concerned. Good luck with the rest of the project. :bye:

Thank you for making the extra effort.  This result will be very useful.

My goal now is to understand these things to the point that they become familiar tools in my own working set.  Your use of an array for the field defs, for example, opens up a new dimension of possibilities (pun not intended).  It's not something I normally think to do, so it's another learning experience.

I really appreciate what you've provided.

qwert,

Glad I could help. Please do ask if you have any questions about how or why I did something particular. :)
