Nages,

I create a Scroll Panel with some Objs and save the obj on adata array

To manage open a Xbrowse with aData

I wish erase the obj on TscrollPanel When Click (SetCheck) on one items on xbrowse except product number 1

and del item on adata and refresh the oBrw

how I can resolve ?

I Tried with ( but run bad)

FOR i := 1 TO LEN(oBrw:aCols)
oCol := oBrw:aCols[ i ]
oCol:bLDClickData := { || Erase_Items(oBrw,oPanel) }
NEXT

Function Erase_Items(oBrw,oPanel)
local nItem:= oBrw:aArrayData[ oBrw:nArrayAt ][2]
aDel(oBrw:aArraydata,nItem-1)
// xbrowser oBrw:aArraydata
oPanel:aControls[nItem]:destroy()
oBrw:refresh()
oPanel:refresh()
return nil



Code: Select all  Expand view
Function Manage_Items(aData,oBrowse)
    local oDlg
   local oBar
   local oFont
   local oBold
   local nWd  := GetSysMetrics(0) * .30
   local nHt  := (GetSysMetrics(1) / 3.5 ) -20
   local oBtn := array(3)
   local aBmp:= {" ","elimina.bmp"}
   local aCols    := {}


     For n= 1 to Len(aData)
        If  !aData[n][5]
           else
          AAdd( aCols, {aData[n][1],n,!aData[n][5]})
       Endif
     Next

   DEFINE DIALOG oDlg SIZE nWd, nHt PIXEL ;   //TRUEPIXEL
       TITLE  "Products" ;
       FONT oFont   COLOR CLR_BLACK, RGB( 245,245,235)  ;
       STYLE nOR( DS_MODALFRAME, WS_POPUP, WS_CAPTION, WS_SYSMENU, ;
                  WS_MINIMIZEBOX)


    @ 10,10 XBROWSE oBrw SIZE -10,-20 PIXEL OF oDlg ;
          DATASOURCE aCols ;
          COLUMNS 1,3 ;
          HEADERS "Descrizione","R" ;
          COLSIZES 300, 40 ;
           NOBORDER  FONT oFONT

        WITH OBJECT oBrw
            :lHScroll:=.f.
            :lRecordSelector:= .F.
            :lDrawBorder := .t.

          WITH OBJECT :aCols[ 2]
             :SetCheck(aBmp, .t. )
             :nHeadBmpNo    := 2
          END
          :CreateFromCode()
       END

      ACTIVATE DIALOG oDlg CENTERED
    RETURN NIL

To delete nth control of a Panel/dialog/window
Code: Select all  Expand view
oPanel:aControls[ n ]:End()
HB_ADel( oPanel:aControls[ n ], n, .t. )


To delete current row in XBrowse ( applies to arrays, dbf, ado or any data source)
Code: Select all  Expand view
oBrw:Delete()
oBrw:Refresh()


This code:
Code: Select all  Expand view
FOR i := 1 TO LEN(oBrw:aCols)
oCol := oBrw:aCols[ i ]
oCol:bLDClickData := { || Erase_Items(oBrw,oPanel) }
NEXT


can be written as:
Code: Select all  Expand view
oBrw:bLDClickDatas :=  { || Erase_Items(oBrw,oPanel) }

Mr Rao

this del the record on Browse but on Panel there are also the btnbmp (oBj)
Code: Select all  Expand view

Function Erase_Items(oBrw,oPanel)
   local  nItem:=  oBrw:aArrayData[ oBrw:nArrayAt ][2]

   oBrw:Delete()
   oBrw:Refresh()

        oPanel:aControls[ nItem ]:End()
        HB_ADel( oPanel:aControls[ nItem ], nItem, .t. )

        oPanel:refresh()

   return nil


Image

the btnbmps there are also on Panel scroll as you can see on Video

I tried with

oPanel:CheckResize() and oPanel:Setrange()

Nages

oPanel:aControls[ nItem ]:End()
HB_ADel( oPanel:aControls[ nItem ], nItem, .t. )
ASize( oPanel:aControls, Len( oPanel:aControls ) )
oPanel:SetRange()
oPanel:refresh()


I saw on oPanel:aControls there are also the records

Image

also if I make ASize( oPanel:aControls, Len( oPanel:aControls ) -1 ) then not refresh the panel


if there are any deleted objects the btnbmp should reposition themselves

Image

if I delete products 3 and 4, product number 5 must be positioned after product 2

How I can resolve it ?

Sorry Nages,
but not erase the btnbmp on Panelscroll

I made

//I want erase only from second column of oBrw
oCol := oBrw:aCols[ 2 ]
oCol:bLDClickData := { || Erase_Items(oBrw,oPanel) }



Function Erase_Items(oBrw,oPanel,aData,oDlg,oFontSmall)
local nItem:= oBrw:aArrayData[ oBrw:nArrayAt ][2]

oBrw:Delete()
oBrw:Refresh()

DeleteControl( oPanel, nItem )

return nil

function DeleteControl( oPanel, nItem )

local nTop, nLeft

for n := Len( oPanel:aControls ) to nItem + 1 STEP -1
oPanel:aControls[ n ]:nTop := oPanel:aControls[ n - 1 ]:nTop
oPanel:aControls[ n ]:nLeft:= oPanel:aControls[ n - 1 ]:nLeft
next
oPanel:aControls[ nItem ]:End()

Of Course your test run ok But

I tried to erase all buttons except one , then I press the scrollbar of panel scroll and I had this

Image

when I had only two buttons I cannot delete printer button

Image


then I have another situation
the final user can insert items directly on tpanel, only on another dialog can delete the btnbmp
these items are quick links to recall some application procedures, so each btnbmp is associated with an action to a Function.
the final user can insert items from a Menu popup as this

Code: Select all  Expand view

MENU oMenu POPUP
     MENUITEM "Procedure1"   ;
       ACTION   CreateBtn( oPanel, "C:\work\fwh\bitmaps\pngs\image1.PNG", @nRow, @nCol,"Procedure1",{||Dummy1()} )
     MENUITEM "Procedure2"   ;
       ACTION   CreateBtn( oPanel, "C:\work\fwh\bitmaps\pngs\image2.PNG", @nRow, @nCol,"Procedure2",{||Dummy1()} )
     ENDMENU
   ACTIVATE POPUP oMenu WINDOW oPanel AT 0, 0

Yes. The function I provided does not allow the last control to be deleted.

Yes. I understood.

Do have you tried deleting all the btnbmps and moving the scrollbar?

It makes this mistake for me

Nages,
I need to save the buttons in the archive (links.dbf) because the application must display the buttons at other times when the application is used by users
I sent a test

Please try this function instead

   local nTop, nLeft, nLen, n

   if ( nLen := Len( oPanel:aControls ) ) == 1 .or. nItem == nLen
