XBrowse: Using Get for incremental Seek/Filters

[Silvio.Falconi]

You have to reset the items of the combobox on the basis of columns where oCol:lHide == .f.

How I not understood, I not Know how Make it

and then
aCols := { ;
{ "FIRST", "Nome",, 120, },;
is as // { field, header, picture, size, justify, sortorder } ?

Nages,

I remember you the combobox on the dialog

@ 40, 400 COMBOBOX oCbx VAR cHead ITEMS aHead ;
SIZE 150,200 PIXEL OF oTabella ;
ON CHANGE ( oBrw:Seek( "" ), ;
oBrw:cFilterFld := oBrw:oCol( cHead ):cExpr, ;
oBrw:SetFocus() )


where we list the caption of the columns
but id the user change the columns configuration , how I can resolve ?

you sad me "You have to reset the items of the combobox on the basis of columns where oCol:lHide == .f. "

But I not understood How make it


today I set on xbrowse these lines

:lAllowRowSizing := .F.
:lAllowColSwapping := .F.
:lAllowColHiding := .F.

the user cannot change the column configuration

then I insert on a menu

MENUITEM "Colonne" ACTION ( SelectColumns( oBrw ),;
ChangeBrowse(oBrw,oCbx) )


on the function SelectColumns( oBrowse ) I open the configuration of Browse as you can see on this picture



if the user select a checkbox and then click on ok the procedure call this function

Code: Select all | Expand

Function ChangeBrowse(oBrw,oControl)
            local aItems:= {}
            AEval( oBrw:aCols, { |o| If( o:lHide,,AAdd( aItems, o:cHeader ) ) } )
            oControl:setItems(aItems)
            oControl:refresh()
        return nil

 

oControl is the oCbx ( combobox ) on the dialog

when I call this function make error on combobox

Code: Select all | Expand

   Error description: Error BASE/1004  No exported method: CEXPR
   Args:
     [   1] = U
