QR ON COMMAND
QR ON COMMAND ( area ; methodName )
| Parameter | Type | Description | |
|---|---|---|---|
| area | Integer | → | Reference of the area |
| methodName | Text | → | 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.
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ドル is the reference of the area (Longint).
- 2ドル is the command number of the command that was selected (Longint). You can compare this value with the following constants of the QR Commands theme:
| Constant | Type | Value | Comment |
|---|---|---|---|
| qr cmd generate | Integer | 2008 | Use of command QR RUN recommended |
| qr cmd page setup | Integer | 2006 | |
| qr cmd print preview | Integer | 2007 |
Note: When planning on compiling the database, it is necessary to declare both 1ドル and 2ドル 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ドル;2ドル).
If you pass an invalid area number, the error -9850 will be generated.
