For this you need event handler that are called after the jump. You can add a button to your form, by clicking the TButton (square button with an "OK" in the middle tbutton.png) on the Standard component palette and place it with a click on your form. A TLabel is one of the most basic components that can be used on forms. Most labels are the marking of other components, such as Edit fields, Memos, StringGrids and so on. TLabels provide a variety of events available to you but not required in most cases. You can add a label to your form, by clicking the TLabel (text symbol Abc) on the Standard component palette and place it with a click on your form. To change the default label Label of a new inserted TLabel on a form, you can proceed as follows: On your form with one click, select the TLabel. Go on properties in the Object Inspector tab. Select the property Caption and change it in the next edit field. In the same way, you can select the property Name and give the label a better name.
