TCustomListBox.Clear Method

Deletes all items from the list box.

Pascal

procedure Clear; override;

C++

virtual __fastcall Clear();

Description

Use Clear to delete all of the items in the list box at once. Although the items in a standard list box are of type TStrings, use the Clear method of the list box rather than calling the Clear method of the Items property. This allows descendants of TCustomListBox to perform any other necessary clean-up in the Clear method, in addition to deleting the items from the Items property. Thus, applications should use

Copy Code

ListBox1.Clear;

Copy Code

ListBox1->Clear();

rather than

Copy Code

ListBox1.Items.Clear;

Copy Code

ListBox1->Items->Clear();
