setTreeTable(TreeTable treeTable)
Sets the tree table this cell belongs to. |
Method Detail |

ColumnLocation getLocation()
In case location of a column changes, it is necessary to call the invalidateAll
methods on the TreeTable
to prevent incorrect rendering.
int getSpan(javax.swing.tree.TreeNode node)
The returned value implicates, over how many cells the cell in this column (in row determined by node) should span. This is analogical to colspan property of html element td.
node
- The tree node
boolean isVisible()
In case the visibility changes, it is necessary to call the invalidateAll
methods on the TreeTable
to prevent incorrect rendering.
Component newCell(MarkupContainer parent, java.lang.String id, javax.swing.tree.TreeNode node, int level)
newCell(TreeNode, int)
returned null.
parent
- The parent to which the cell must be added. Can also be used to find the TreeTable
instance (using parent.findParent(TreeTable.cass)
)id
- The component idnode
- TreeNode for the celllevel
- Convenience parameter that indicates how deep the node is in hierarchy
IRenderable newCell(javax.swing.tree.TreeNode node, int level)
IRenderable
instance for given node. IRenderable
can be used as
lightweight alternative to regular Component for cells, that don't require user interaction
(just display data).
If this method returns null, newCell(MarkupContainer, String, TreeNode, int)
is used to popuplate the cell.
node
- TreeNode for the celllevel
- Convenience parameter that indicates how deep the node is in hierarchy
Component newHeader(MarkupContainer parent, java.lang.String id)
parent
- The parent componentid
- The component id
void setTreeTable(TreeTable treeTable)
treeTable
- The tree table
