    - "ownFont";
      The attribute "ownFont"; returns TRUE if an object (for example, a textEdit, a slider, a zoom navigator or a tree widget) uses its own font. If the value is FALSE, the object uses its parent widget`s font.

Scheduler.ewo

The Scheduler EWO allows the display and editing of time ranges in a definable grid of one or more days. The. The Scheduler.ewo is located under wincc_oa_path//bin/widgets/.

An EWO (External Widget Object) is a graphical object (a Widget) created by some external party (customer) that can be embedded into any WinCC OA Panel. It is platform independent. It is implemented in C++ with the platform independent Qt graphical toolkit from Trolltech. For details, refer to qt-project.org.

The scheduler.ewo supports the functionality of the WinCC OA scheduler and is included in the WinCC OA installation. It can, however, also be embedded as an object into any panel. For more information, see chapter EWO (External Widget Object).
