public class TLcdLayerTree extends JTree
JTree, set up to render the layers tree structure of a view. The assumptions this
layer tree makes, that are not made by a standard JTree, are that objects present in
the tree model are:
Note that these assumptions hold when using TLcdLayerTreeModel or TLcdFlatListTreeModel.
For performance reasons, it also sets large model to
true, which means all rows should have equal height. If a cell renderer is used
that has different row heights for different values, this property must be set to
false. This assumption is ok in combination with for example a TLcdLayerTreeNodeCellRenderer.
When the used TreeCellRenderer for this tree
contains an AbstractButton mouse clicks on this button will be
passed on to the button after the TreeCellRenderer#getTreeCellRendererComponent
has been called.

public TLcdLayerTree(ILcdTreeLayered aView)
Create a new tree set up to render the layer tree structure of the ILcdTreeLayered aView.
A TreeModel, representing the hierarchical layer structure
of the view, and an adjusted TreeCellRenderer are set
on the tree.

setMinimumVisibleRowCount(int).public void setMinimumVisibleRowCount(int aMinimumVisibleRowCount)
Sets the minimum visible row count, which affects the preferred size of this JTree when in a scroll pane. This behavior is especially useful when overlaying a JTree on a map, where you want to avoid unused empty space but allow it to grow when needed.
When added to a scroll pane, a JTree defines its
preferred size based on
JTree.getVisibleRowCount(). This sub-class defines an additional minimum visible row
count. The preferred size is then kept between minimum and normal row count, based
on the amount of data currently being displayed. Suppose a minimum row count of 5 and a
normal row count of 10. If the tree currently shows 2 rows, space is made available for 5. If
it is displaying 7 rows, space for 7 rows is available. If it is showing 50 rows, space is
available for 10 rows. If you make the minimum and regular visible row count equal, you get
the default JTree behavior.
Note: this property is currently only respected when using fixed row heights (the default setting for this class).
