@brief An empty layout item \internal The AutoSpacerLayoutItem is automatically put into each corner cell of the planeLayout grid: one of its reference-layouts is a QVBoxLayout (for the top, or bottom axes resp.), the other one is a QHBoxLayout (for the left/right sided axes). The spacer reserves enough space so all of the AbstractAreas contained in the two reference-layouts can display not only their in-bounds content but also their overlapping content reaching out of their area. KD Chart's layouting is applying this schema:
+------------------+-------------------------+-----------------+ | +--------------+ | +---------------------+ | +-------------+ | | | | | | QVBoxLayout for | | | | | | | AUTO | | | the top axis/axes | | | AUTO | | | | SPACER | | +---------------------+ | | SPACER | | | | ITEM | | | | | | ITEM | | | | | | | | | | | | | +--------------+ | +---------------------+ | +-------------+ | +------------------+-------------------------+-----------------+ | +--------+-----+ | +---------------------+ | +-------+-----+ | | | | | | | | | | | | | | | | | | | | | | | | | | | QHBox- | | | | | | | Right | | | | | Layout | | | | | | | | | | | | | | | | | | | axes | | | | | for | | | | | | | | | | | | | | | | | | | layout| | | | | the | | | | DIAGRAM(s) | | | | | | | | | | | | | | | | | | | | left | | | | | | | | | | | | | | | | | | | | | | | | axis | | | | | | | | | | | | or | | | | | | | | | | | | axes | | | | | | | | | | | | | | | | | | | | | | | +--------+-----+ | +---------------------+ | +-------+-----+ | +------------------+-------------------------+-----------------+ | +--------------+ | +---------------------+ | +-------------+ | | | | | | QVBoxLayout for | | | | | | | AUTO | | | the bottom axes | | | AUTO | | | | SPACER | | +---------------------+ | | SPACER | | | | ITEM | | | | | | ITEM | | | | | | | | | | | | | +--------------+ | +---------------------+ | +-------------+ | +------------------+-------------------------+-----------------+
A typical use case is an Abscissa axis with long labels:
2 -| | 1 -| | 0 -+------------------------------------ | | | | | Monday Tuesday Wednesday Thursday Friday
The last letters of the word "Friday" would have been cut off in previous versions of KD Chart - that is if you did not call KDChart::Chart::setGlobalLeading().
Now the word will be shown completely because there is an auto-spacer-item taking care for the additional space needed in the lower/right corner.

Derived classes like KDChart::AbstractArea are providing additional action here.

Inform the item about its widget: This enables the item, to trigger that widget's update, whenever the size of the item's contents has changed.
Thus, you need to call setParentWidget on every item, that has a non-fixed size.
