If the user sets a maximum number of text lines in the settings, this number was translated into a maximum height in pixels using QFontMetrics::lineSpacing() before this commit. In KStandardItemListWidgetInformant::itemSizeHint(), this maximum height limited the size that is reserved for the item. However, in KStandardItemListWidget::updateIconsLayoutTextCache(), the maximum height was translated back into a maximum number of lines, which limits the number of lines that are created using the QTextLayout. This approach could lead to problems if the real height of the layouted text is 1 pixel more or less than QFontMetrics::lineSpacing() times "number of lines". Now we do not store a "maximum height" inside the "maximum size" explicitly, but store a maximum number of lines and a maximum with (for Compact View) separately, and then use the number of lines also to calculate the required size in KStandardItemListWidgetInformant::itemSizeHint(). This should make sure that the correct height is reserved for each item. Thanks to Christoph Feck and Emmanuel Pescosta for helping to debug this problem and testing the patch.
