Description

The PV VALIDATE CURRENT CELL command validates the contents of the current cell while in entry mode. The current cell remains the same.

This command can only be called from a callback method. For more information on callback methods, refer to the PV Area, Introduction section.

Example

Start by installing the callback method EventMethod, which will be called on double click:

PV ON EVENT(Area;pv on double clicked;"EventMethod")

This method intercepts the user's double-click:

  `EventMethod method

 C_LONGINT($1) `4D View area reference

 C_LONGINT($2) `Event

 C_LONGINT($3) `Modifying key code

 C_LONGINT($4) `Column number

 C_LONGINT($5) `Row number

 C_LONGINT($6) `Ascii code of the key

 C_BOOLEAN($0) `Value to return

 

 $0:=False

 

 If($2=pv on double clicked) `In case "EventMethod" will also be called for other events

    BEEP

    PV VALIDATE CURRENT CELL($1) `Cell contents are validated

 End if
