Control - SetFocus Method

Member of Control (PRIM_CTRL)

Details

The SetFocus sets focus to the control.

Most focus processing in LANSA is handled automatically, however, on occasion it aids usability to position the cursor to a particular edit.

Example

When clicking a button to show a previously hidden panel, focus would naturally stay with the button that was clicked.

SetFocus is used here to position the cursor in the first edit.
