[Gambas-user] Filtering listbox list

[Shannon Kuchler]



-I think I figured it out

Public Sub TextBox4_KeyRelease() 
Dim i As Integer
Dim l As Integer

ListBox6.Clear
      

      If TextBox4.text > "z" Or TextBox4.text < " " Then Return 
      For l = 0 To ListBox1.Count
        Inc i
          If ListBox1[i].Text Like TextBox4.Text & "*" Then ' found another
          ListBox6.Add(ListBox1[i].Text) 
      Endif
      Next

End

Sorry I didn't explain myself well enough maybe I'll get it right this time.
I'm trying to filter the List of a ListBox based on the text property of a textBox with the results being added to another listbox during a key eventI hope that make more sense

Just to be clear, are you saying that you want to filter the List of a ListBox based on the Text property of a TextBox? (I
actually have to wonder how you know it can be done.)

ListBox has no 'mask' property. So, since ListBox.List is a string array, you would have to:
1. maintain a separate string array,
2. fill the ListBox.List from that original array,
3. on a key event, clear the List and then refill it incrementally from the original array using String[].Find (with Mode=gb.Like).

If you instead are wanting to do incremental searching, you can do that relatively easily by setting the ListBox.Index with
ListBox.Find. But, you'll want to use the KeyRelease event.

[code]
Public Sub Form_Open()

  With ListBox1
    .List = ["abcd", "abce", "abde", "bcde", "bdef"]
    .Mode = Select.Single
  End With

  TextBox1.SetFocus

End

Public Sub TextBox1_KeyRelease()

  ListBox1.Index = ListBox1.Find(TextBox1.Text & "*", gb.Like)

End
[/code]
