QR ON COMMAND


QR ON COMMAND ( area ; methodName )

Parameter	Type	Description
area	Longint	Reference of the area
methodName	String	Name of the replacement method

Description

The QR ON COMMAND command executes the 4D method passed in methodName when a Quick Report command is invoked by the user, by the selection of a menu command or by a click on a button.

Note: This command only works in the context of a quick report area included in a form.

If area equals zero, methodName will apply to each Quick Report area until the database is closed or until the following call to the command is made: QR ON COMMAND(0;"").

methodName receives two parameters:

$1 is the reference of the area (Longint).
$2 is the command number of the command that was selected (Longint). You can compare this value with the constants of the QR Commands theme.

Note: When planning on compiling the database, it is necessary to declare both $1 and $2 as Longints, even if you do not use them.

If you want the initial command to be executed, you need to include the following in the called method: QR EXECUTE COMMAND($1;$2).

If you pass an invalid area number, the error -9850 will be generated.
