Form widget is two column grid where each row has a label and a widget (usually an input). The last row of the grid will contain the appropriate form control buttons if any should be shown. Setting OnSubmit will set the submit button to be visible and call back the function when tapped. Setting OnCancel will do the same for a cancel button. If you change OnSubmit/OnCancel after the form is created and rendered, you need to call Refresh() to update the form with the correct buttons. Setting OnSubmit/OnCancel to nil will remove the buttons.
