My ListBox contains some very long items. I don't want to change its size so is it possible to add a horizontal scroll bar to my ListBox?

 

 

1.

  Start a new project using File | New Application.

 

2.

  Add a ListBox. Insert items that exceed the visible area.

 

3.

  Edit the OnCreate event of your form:

 

void __fastcall TForm1::FormCreate(TObject *Sender)

{

    int width = 0;

    for(int x = 0; x < ListBox1->Items->Count; x++)

    {

        int text = ListBox1->Canvas->TextWidth(ListBox1->

            Items->Strings[x]);

        if(text > width)

            width = text;

    }

    ListBox1->Perform(LB_SETHORIZONTALEXTENT, width, 0);

}
