  • Mofdify Input dropdownlist

    From Jack Konings@21:1/5 to All on Thu Feb 24 02:40:10 2022
    Hi,

    On a window I've got a combobox as (sorted) dropdownlist. The box is filled with items which all have the same format like "R-"+9999 (like 'R-1234'). The list is used to select more detailed data.
    Currently the user punches in "R-" followed by the number. In doing this the combobox displays the item which best fits the input.
    Since the format is always the same punching in the "R-" is inefficient. It would be more convenient if the user just has to punch in the number and the best "R-9999" match would be shown.

    I tried to get this behavior by defining a keyup event, "catch" the numbers and add "R-' to them. This didn't work well and i'm starting to doubt keyup is the right way to do this.

    Can someone give me a hint as how to make the desired behavior?
    TIA.

    Why not use an SLE ?

    Did you check on ListBoxSelect method ?

    METHOD ListBoxSelect(oControlEvent) CLASS frmMyWindow
    SUPER:ListBoxSelect(oControlEvent)
    *
    IF oControlEvent:Control:NameSym == #MYCOMBO

    The hacker solution: Push "R-" into the keyboard buffer, before entering the dialog. So you've entered it for them.

    And how would i do that?

    Don't include the "R-" in the list you show them. "Doctor, it hurts when I do this!" Probably ignore "R" and "-" when they do press them, since you've trained some of them to type it. Might even say on screen "Enter the R-[number] you want more
    information on?"

    Because I want the user to have the possibility to select the item with mouse (and see all the items).

    Did you check on ListBoxSelect method ?

    Yes, but i fail to see how that would solve my issue.

    Hi Jack

    some month ago i posted a sleInputTimer class in the X#-Forum. With some
    small modifications the code seems to work with a DROPDOWNLIST Combo too. To see what's going on, i added some console output to the attached
    cmbTimerSearch class. Just inherit your comboBox from cmbTimerSearch and
    give it a try.

    What the CB_SELECTSTRING msg does is described here:

    https://docs.microsoft.com/en-us/windows/win32/controls/cb-selectstring

    regards
    Karl-Heinz

    CLASS cmbTimerSearch INHERIT ComboBox
    PROTECT _lTimerActive AS LOGIC
    PROTECT _nInterval := 400 AS DWORD
    PROTECT _cSearch AS STRING

    METHOD Destroy() CLASS cmbTimerSearch

    SELF:StopTimer()

    SUPER:Destroy()

    RETURN NIL

    METHOD Dispatch ( oEv ) CLASS cmbTimerSearch
    LOCAL oEvent AS Event


    oEvent := oEv


    DO CASE

    CASE oEvent:message == WM_CHAR

    _cSearch += CHR (oEvent:wParam )


    CASE oEvent:message == WM_KEYUP

    SELF:StartTimer()


    CASE oEvent:message == WM_KEYDOWN

    SELF:StopTimer()


    CASE oEvent:message == WM_KILLFOCUS

    SELF:StopTimer()


    CASE oEvent:message == WM_TIMER


    IF ! Empty ( _cSearch )

    SELF:StopTimer()

    ? "Search for:" , _cSearch := "R-" + _cSearch

    ? SendMessage( SELF:Handle() , CB_SELECTSTRING , DWORD (
    _CAST , -1 ) , LONG (_CAST, String2Psz ( _cSearch ) ) )

    _cSearch := ""

    ENDIF


    ENDCASE


    RETURN SUPER:Dispatch ( oEvent )


    METHOD init (oOwner, nID, oPoint, oDimension, kComboType, kStyle ) CLASS cmbTimerSearch

    SUPER:init (oOwner, nID, oPoint, oDimension, kComboType, kStyle )

    RETURN SELF

    METHOD SetTimerInterval ( n ) CLASS cmbTimerSearch

    _nInterval := n

    RETURN SELF

    METHOD StartTimer() CLASS cmbTimerSearch


    IF ! _lTimerActive

    IF SetTimer(SELF:Handle(), 4711 , _nInterval , NULL_PTR) == 4711

    _lTimerActive := TRUE

    ENDIF

    ENDIF

    RETURN _lTimerActive

    METHOD StopTimer() CLASS cmbTimerSearch


    IF _lTimerActive

    And how would i do that?

    Outside VO, but you probably have these WINAPI functions available: https://stackoverflow.com/questions/10787949/insert-into-windows-keyboard-buffer

    Ah, this gives me a push in the right direction. Thanks, I will give it a try.

    That's a little bit over my paygrade........
    I'll give the sample of Karl-Heinz a go.

    OK. Don't you initialize the search string you have the customer type in to navigate that list? Can't you set it to "R-" before calling the display routine? I don't do VO, but we have stuff like this in xHarbour...
