I use oCol:Cargo to save some parameters.
Since FW 23.07 it does not work anymore, maybe due to:

LinkList: Method Sort( [lAsc], [lRecurse], [nCol] ) enhanced with
three new parameters.
Param.3 nCol: Default 0: Sorts on nCol of Cargo Array

How can I find a workaround?
Suggestions are welcome.

... samples\webview.prg y webvieweval.prg

* Mejora: La clase TListView es compatible con Unicode. Prueba el ejemplo: samples\testvie1.prg

* Clase LinkList: Se ha mejorado el método Sort( [lAsc], [lRecurse], [nCol] ) con tres nuevos parámetros:

1.- lAsc: .T. o "A" para ordenación ascendente y .F. o ...

... Please review samples\webview.prg and webvieweval.prg

* Enhancement: TListView class is now made Unicode compatible
Try samples\testvie1.prg

* LinkList: Method Sort( [lAsc], [lRecurse], [nCol] ) enhanced with
three new parameters.
Param.1 lAsc: .T. or "A" for ascending sort and .F. OR "D"
for ...

First, you need to modify the fwh program
fwh\source\classes\linklist.prg

In this program please replace the existing METHOD Sort() with this revised new method:
METHOD Sort( lAsc, lRecurs ) CLASS TLinkList

local oPrev, oNext, n, aItems := {}
local oItem
local bSort

DEFAULT lAsc := .t ...

... si el programador no especifica ninguna imagen de mapa de bits, xBrowse
proporciona imágenes de mapas de bits por defecto.

* TREES: (Clase LinkList)
- Hereda de la clase TTreeItem.
Ahora es posible derivar la clase de TTreeItem y crear árboles con la misma sintaxis de comando usando
la ...

... if treeitem:cargo is a hash.

- For tree browses, if the programmer does not specify any bitmaps, xbrowse provides
default bitmaps.

* TREES: (LinkList class)
- Inheritance from TTreeItem class.
It is now possible to derive class from TTreeItem and create trees with the same
command syntax using ...

please see these methods
METHOD OpenAll()
METHOD Expand( nLevel )
METHOD Collapse( nLevel )
in linklist.prg

This knowledge database is very useful.
You have full text search and you can open links directly. There is space for extra notes, too.
With the program you are independent of the browsers you use.

Instead of the approach I suggested above, I am posting a sample using LinkList, but without reading the data into the memory. I have used states.dbf and customer.dbf in the fwh\samples folder as Parent and Child dbfs respectively.

I suggest you compile and test the program and then you may adopt to ...

... is not homogenous to the rows to be inserted on the xbrowse from the sales table. That behavior is known to many on this forum as xbrowsing a LinkList (or tree). As in:
oBrw:SetTree( ::buildTree() )

The problem with xbrowsing a tree is that the tree must be created in memory ...

... from a different table.

Currently you can do this with fwh by xbrowsing a tree. But you can't make a tree out of large table -such as any real world master table. After about 10k records, an in memory linklist stops being practical. Any real world master table will be 20 times that size.

Hello,

possible solution:

linklist.prg

METHOD Add( cPrompt, nLevel, hBmpOpen, hBmpClose, lOpened, bAction, uCargo ) CLASS TLinkList local oItem DEFAULT lOpened := .f., nLevel := If( ::oFirst != nil, ::oFirst:nLevel,) oItem := TTreeItem():New( cPrompt, nLevel, hBmpOpen ...

... for xbrowse:otree skipper or xbrowse skipper to check if treeitem:cargo == condition?


Kind regards,
Frances
It is not impossible to change LinkList ( oTree ) skipper. But providing filtering mechanism in the Trees involves more changes to the class including number of rows, serial number of ...
