ListBox displays a collection of items in a scrollable list. We use ListBox to display a scrollable list of items that users can select, add, or delete. ListBox is a wrapper for the Windows listbox control.
We can browse all the properties, methods, and built-in properties of the DelphiVCL.ListBox using dir() command:
1 2 3 |
import DelphiVCL dir(DelphiVCL.ListBox) |
See the responses in command prompt:

Here is the working example of the implementation of DelphiVCL.ListBox:
1 2 3 4 5 6 7 8 |
# List box creation lboxCountry = ListBox(pgOne) lboxCountry.SetProps(Parent=pgOne) lboxCountry.SetBounds(145,88,121,60) lboxCountry.Items.Add('RUSSIA') lboxCountry.Items.Add('USA') lboxCountry.Items.Add('INDIA') lboxCountry.Items.Add('AUSTRALIA') |
To see the result, let’s run the complete script:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 |
