Hi, Nigel --
I've never used the ColumnView (or other View) to sort the data -- I always
sort the arrays where I keep data, and then re-fill the ColumnView or other
View, if necessary. Your question raised a point that I've never explored,
so I dug into it and found that you CAN sort data in a View, using the
built-in capabilities of the View object. The documentation is on this
page:
http://gambasdoc.org/help/comp/gb.qt4/_columnview_columns?v3
Frankly, I sometimes find the Gambas online documentation to be a little
cryptic, so (like usual) I wrote a simple program to explore and demonstrate
sorting in a ColumnView. Here is the essential code block, especially note
the inner/2nd "If-Endif" block:
'Note that when you change the sort of the ColumnView from one column to
another,
'the sort column header will display a down-arrow symbol.
Public Sub Button1_Click()
If TextBox1.Text 'In other words, if TextBox1.Text is not NULL.
If TextBox1.Text = "0" Or If TextBox1.Text = "1" Or If TextBox1.Text =
"2" Then
ColumnView1.Columns.Ascending = True
ColumnView1.Columns.Sort = Val(TextBox1.Text)
Else
Message.Info("Type a Column ID: '0','1', or '2'", "OK")
TextBox1.Text = ""
Endif
Else
Message.Info("Type a Column ID: '0','1', or '2'", "OK")
TextBox1.Text = ""
Endif
End
My e-mail address is: nicho...@acegroup.cc
If you send me your e-mail address, I'll send you a tar.gz file of the
complete program, just so you can play with it and see how the sort works.
Best regards,
Jon Nicholson
