- Indexed control
Defines the next control that will be in edit in the current window. This field will have "focus": keyboard actions performed by the user will be directed to this field.
// Puts the input on the "EDT_Edit2" control
ScreenFirst(EDT_Edit2)
// Changes the next control in edit
IF ControlCurrent() <> EDT_Name THEN ScreenFirst(EDT_Name)
Sintaxis
ScreenFirst([<Control used> [, <Index>]])
<Control used>: Optional control name 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 gain focus will be in edit.
If this parameter corresponds to a control that cannot gain focus (invisible control, static control, and so on), the input will start from the next control according to the tab order. <Index>: Optional integer Index for an indexed control. Observaciones Focus gain When a control gains 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.).
Please note Not all field types (e.g. "Label" fields) can take focus. ScreenFirst used with a window If <Control name> corresponds to the name of a window, the window becomes active. The control that will gain focus in this window will correspond to: - the last control previously in edit in this window,
- the first control that can gain focus in this window (if no data was previously entered).
Events executed when ScreenFirst is used 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 current field is not executed if the function ScreenFirst is used in one of the events associated with this field. ScreenFirst, SetFocus and SetFocusAndReturnToUserInput These functions have a different behavior: - SetFocusAndReturnToUserInput stops the current process to force the input in the specified control.
- ScreenFirst defines which control will receive input focus (when the current code stops and input focus is set back to a control).
- SetFocus stops the current process, defines which control will receive input focus and resumes the current process.
Error A WLanguage error occurs if <Control name> does not correspond to a control in the current window.
