Syntax
ScreenFirst([<Control name> [, <Subscript>]])
<Control name>: Optional character string (with or without quotes)
Name of control (including columns of a Table control) or window that will be in edit mode.
If this parameter corresponds to the name of a window, the window will be activated and a control that can take focus will be in edit.
If this parameter corresponds to a control that cannot take focus (invisible control, static control, and so on), the input will start from the next control according to the tab order.
<Subscript>: Optional integer
Subscript for a subscripted control.

Remarks

Focusing

When a control takes focus, this is indicated in different ways depending on the type of the control:
  • Blinking cursor (or "Caret") for the edit controls.
  • Dotted rectangle for the other types of controls (Button, List Box, Radio Button controls, etc.).
Caution: Some types of controls cannot take focus ("Static" controls for example).

ScreenFirst function used with a window

If <Control name> corresponds to the name of a window, the window is activated. The control that will take focus in this window will correspond to:
  • the last control previously in edit in this window,
  • the first control that can take focus in this window (if no input was previously performed in this window).

Events that occur when using function ScreenFirst

In most cases, exit events (from the current control or window) and entry events (in the specified control or window) are run when ScreenFirst is called.
Exception to this rule: The exit code of the selected control is not run if ScreenFirst is used in one of the events of this control.

ScreenFirst, SetFocus and ReturnToCapture

These functions have a different behavior:
  • ReturnToCapture stops the current process to force the input in the specified control.
  • ScreenFirst defines the next control that will be in edit (when the current code stops and when the input resumes).
  • SetFocus stops the current process, describes the next control that will be in edit and resumes the current process.

Error

A WLanguage error occurs if <Control name> does not correspond to a control found in the current window.

Subscripted control

<Subscript> allows you to specify the subscript of a subscripted control. You can also use the name of the subscripted control. For example:
ScreenFirst(SAI_Saisie1, 1) = ScreenFirst(SAI_Saisie1[1])
