Description
-------

I've added support for sensor displays in KSysGuard to have row spans and column spans.

Apart from adding rowSpan and columnSpan arguments to the method signatures, I've also removed the internal list (WorkSheet::mDisplayList) used to contain all the sensor displays. This list used to be used to derived the row and column of the displays based on their index in the list. Since I now need to maintain rowSpan and columnSpan information as well, I just removed the list entirely and get all my data from mGridLayout. As a result, another change in the method signatures is the replacement of the "index" parameter with "row" and "column" parameters.

An extra advantage of doing it this way is that widgets don't shift around when resizing the grid. Another advantage is that blank spaces between the widgets are now possible. Not to mention, not maintaining the layout information outside of the actual layout component (mGridLayout) seems a clearer design to me.


This addresses bug 311925.
