Custom Object
The custom object is a sheet object specifically intended to carry custom defined OCX replacement controls.
The Custom Object: Object Menu can be accessed from the Object menu, when the custom object is the active object.
Replacement controls are windowless OCX controls programmed by QlikTech, yourself or third party vendors, which comply with the specifications for QlikView replacement OCX controls. The OCX control will be drawn in a rectangle on the sheet outlined by the underlying custom object. Communication between the OCX control and the QlikView document is maintained via the internal macro interpreter.
The QlikView installation CD comes with a few sample OCX replacement controls. These are provided as is and with full VB source code. You may use them as they are or modify the source code to better suit your needs. (I.e. QlikTech does not offer support on these sample controls.)
