sorting listbox by type of file

General
1

below is my current routine , it will load a listbox, it only sorts by name.

  1. is there a way to sort by type putting all directories at the top or the list, files at the bottom?
  2. for f folderitem is there a method or class that returns the size of the file ? ex:: f.sizeoffile ?

[code]For Uct As Integer = 1 to ListBoxCount
Dim f As FolderItem = appFolder.Item(Uct)
If f <> Nil Then
iBox.AddRow
r = iBox.LastIndex
iBox.Cell(r, 0) = f.Name
iBox.Cell(r, 1) = str(f.ModificationDate)
iBox.Cell(r, 2) = “”
if f.Directory = true then
iBox.RowPicture® = folderiCon16
end if
End If
Next

iBox.ColumnsortDirection(0)=ListBox.SortAscending
// iBox.ColumnType(0) = 2 // add checkboxes
iBox.SortedColumn=0 //first column is the sort column
iBox.Sort
[/code]

Have you checked the docs http://documentation.xojo.com/index.php/FolderItem ?

I’d use the listbox.comparerows event instead of what you are doing

http://documentation.xojo.com/index.php/ListBox.CompareRows

i don’t get docs when i click on the Help (?) button so no i did not check there. but i did do the . + [TAB] list and did not see anything that returns file size.

i got the link
so the comparerows will the listbox. but how do i sort it by directory, then files ?

put the necessary code to compare the two sets of fields in the CompareRows event

compare directory first… if they are EQUAL then compare the file names

Dave

so when i am first loading the ListBox i could compare if the file is a Dir or File.
If Dir i could set the rowTag = “d”
Later in the CompareRows Event i could compare the RowTag for the “d” value and if so push that row higher up the list

or would you consider this a crude way of sorting Drectories and Files ?
