I would like to calculate the height of an entry myself, basing on the amount of text that has been added to the titleLabel. In order to achieve that, I have added an extension of DayEntryView:
public class DetailDayEntryView extends DayEntryView
{
public DetailDayEntryView( Entry< ? > entry )
{
super( entry );
setHeightLayoutStrategy( EntryViewBase.HeightLayoutStrategy.COMPUTE_PREF_SIZE );
}
@Override
protected double computePrefHeight( double width )
{
Label titleLabel = ((Label)lookup( ".title-label" ));
if( titleLabel != null )
{
return titleLabel.prefHeight( width );
}
return super.computePrefHeight( width );
}
}
that I use in my own EntryViewFactory:
public class DayEntryViewFactory implements Callback< Entry< ? >, DayEntryView >
{
...
@Override
public DayEntryView call( Entry< ? > anEntry )
{
return new DetailDayEntryView( anEntry );
}
and this code works great in most scenarios, the height of an entry is the same as height of a label.
The problem appears when entries are overlapping. As far as I can see overlapping of entries is still based on their startTime and endTime - so even though an entry can fit in the view after reducing its height, it is still being rendered as it was overlapping with another one:
(dotted lines show the size of the entry when the end time is taken into account)
I understand that this problem is not trivial. In the example above the height of an entry is less than using endTime so there is no overlapping - but when we change the height of an entry so that it is greater than height based on startTime and endTime, some additional overlapping can appear. In that case the width of the label decreases and basing on that, its height increases - so in order to present the whole text to the user, we would have to repeat the process until each entry has a proper height. It is our problem though - and I already have an idea how to solve it (I would have to introduce the maxEntryHeightProperty).
But I cannot do it since endTime is not bound with the current height of the entry when using HeightLayoutStrategy.COMPUTE_PREF_SIZE strategy.
PS. I have already tried to use com.calendarfx.model.Entry#changeEndTime(java.time.LocalTime) but after doing that I receive lots of exceptions:
java.lang.IndexOutOfBoundsException: Index 55 out of bounds for length 55
