How Automation can control QlikView / QlikView OCX
External control of QlikView /QlikView OCX
QlikView objects are accessible by means of Automation from external programs,
E.g. programs written in Visual Basic or C++ supporting Automation.
Such code can be used to control QlikView from other applications or from stand-alone programs.
Stand-alone executable files can be invoked from a QlikView document by means of launch buttons.
QlikView events
A number of predefined events may be used to trigger a macro in the QlikView/QlikView OCX internal VBScript module. All these events also trigger the OnMacro event in QlikView OCX, which can be picked up and acted upon by the host application.
The events are:
| Event ID | Event Description |
|---|---|
| 1 | A macro can be run after opening a QlikView document. |
| 2 | A macro can be run after script re-execution. |
| 3 | A macro can be run after the Reduce Data command. |
| 4 | A macro can be run after a selection in any field in the application. |
| Event ID | Event Description |

| 5 | A macro can be run after a sheet is activated. |
