DCGETBROWSE

[unixkd]

Hi Roger/All

How can I make the command below to have other parameter like:

#command DCGETBROWSE [DATA <d>] [GET <g>] => GetBrowse( <d>, @<g>, GetList )

Example:

Code: Select all

#command DCGETBROWSE [DATA <d>] [GET <g>] => GetBrowse( <d>, @<g>, GetList, aColSize, aColHead, aColWidth) 

FUNCTION GetBrowse( aData, oGet, GetList, aColSize, aColHead, aColWidth )

LOCAL nPointer, oBrowse, oStatic

@ DCGUI_ROW, DCGUI_COL DCPUSHBUTTON SIZE 20,20 PIXEL ;
      CAPTION 'u' FONT '12.Marlett' ;
      ACTION {||PostAppEvent(xbeP_Keyboard,xbeK_SH_DOWN,,oGet)} ;
      NOTABSTOP

@ 0,0 DCSTATIC OBJECT oStatic TYPE XBPSTATIC_TYPE_TEXT SIZE 10,10 ;
      INVISIBLE

       ITEMSELECTED {||oGet:setData(Pad(aData[nPointer,1],20)), ;
                     DC_GetRefresh(oGet), ;
                     oStatic:hide(), ;
                     SetAppFocus(oGet)} ;
       LOSTFOCUS {|a,b,o|o:hide()}

DCBROWSECOL ELEMENT 1 WIDTH 16 PARENT oBrowse

DCEVAL {||oStatic:setPos({oGet:currentPos()[1], ;
                          oGet:currentPos()[2]-oStatic:currentSize()[2]}), ;
          oStatic:setSize({oGet:currentSize()[1]+15,oStatic:currentSize()[2]}), ;
          oBrowse:setSize(oStatic:currentSize()), ;
          oGet:setInputFocus := {||oStatic:hide()}, ;
          oGet:keyboard := {|nKey,b,oGet|SeekFile(aData,nKey,oGet,oBrowse,oStatic)} }

RETURN nil

  RETURN nil
ENDIF

  IF oStatic:isVisible()
    PostAppEvent(xbeBRW_ItemSelected,,,oBrowse)
  ENDIF
  RETURN nil
ENDIF

IF !Empty(cBuffer)
  nFound := AScan(aDir,{|a|a[1]=cBuffer})
  IF nFound > 0
    oBrowse:arrayElement := nFound
    oBrowse:refreshAll()

I don't understand your question.

Are you saying that you want to add 3 more parameters? aColSize, aColHead, aColWidth

[unixkd]

Yes, exactly so that we can have a multi-column browse with possibility of browse header and corresponding column width.

It will be good to be able to specify the column position that will be returned to the GET.

Thanks

Hi Roger/All

DCGETBROWSE DATA aItemDesc GET oItem

Requires DCGETOPTIONS NOEDITNAVKEYS {||.f.} to work correctly but my clients are used to using ENTER key to move from a GET field to another and will not like to change it. Any workaround ?

Thanks

Joe

How can I make the command below to have other parameter like:

I still don't understand what you are asking.

You showed that you know how to make a command with 3 parameters.

How are 6 parameters any different?

[rdonnay]

Requires DCGETOPTIONS NOEDITNAVKEYS {||.f.} to work correctly

WHAT requires this to work correctly?

I don't understand what you are asking.

Start from the beginning and tell me what it is that you are trying to do?

[unixkd]

OK.

The following code is sample from \EXP19\SAMPLE\GETBROWSE

1. Replace the DCGETOPTIONS of the Main() in this sample with DCGETOPTIONS TABSTOP NOSUPERVISE // NOEDITNAVKEYS {||.f.}
Note that I comment out // NOEDITNAVKEYS {||.f.}

2. Recompile and the run the sample.

3. In the first get enter A or B or any Letter. Then press 'DOWN arrow' continuously and notice the behavior of the browse.

4. If you un-comment the NOEDITNAVKEYS {||.f.} by adding it back to the DCGETOPTIONS the program works correctly BUT will not
allow you to use the ENTER key to move from GET cFileName1 to GET cFileName2

Code: Select all

hi

as i understand you want a different Way to navigate when your Customer press ENTER.

you have something like this

Code: Select all

   oGet:keyboard := {|nKey,b,oGet|SeekFile(aData,nKey,oGet,oBrowse,oStatic)} }

STATIC FUNCTION SeekFile( aDir, nKey, oGet, oBrowse, oStatic )
...
IF nKey == xbeK_BS .OR. nKey == xbeK_DEL .OR. nKey == xbeK_TAB
...
ELSEIF nKey == xbeK_SH_DOWN
...
ELSEIF nKey == xbeK_DOWN .AND. oStatic:isVisible()
...
ENDIF
// put this as first !
IF nKey == xbeK_ENTER

while you want to change ENTER put these line first

Code: Select all

IF nKey == xbeK_ENTER
   IF iEdit = .T.  // allow Edit
      PostAppEvent(xbeBRW_ItemSelected,,,oBrowse)
   ELSE
      PostAppEvent(xbeK_DOWN,,,oBrowse)
   ENDIF
ENDIF

DO CASE
   CASE nKey == xbeK_BS .OR. nKey == xbeK_DEL .OR. nKey == xbeK_TAB
...

when lEdit = .F. and press ENTER than Cursor move DOWN in Browse.
is this what you want

Hi Jimmy

I dont understand your solution.

Pls insert the codes required in the seekfile function for me to run directly.

Thanks.

hi,

you want to change behavior of ENTER and you have a o:Keyboard Slot.
so make Change in o:Keyboard and not in Express++ CLASS.
