Constructor Detail

JXTreeTable.TreeTableDataAdapter

public JXTreeTable.TreeTableDataAdapter(JXTreeTable component)

Constructs a TreeTableDataAdapter for the specified target component.

Parameters:

component - the target component

Method Detail

getTreeTable

public JXTreeTable getTreeTable()

isExpanded

public boolean isExpanded()

Returns true if the cell identified by this adapter is currently expanded. Otherwise, it returns false. For components that do not support hierarchical data, this method always returns true because the cells in such components can never be collapsed.

Overrides:

isExpanded in class ComponentAdapter

Returns:

true if the cell identified by this adapter is currently expanded; Otherwise, return false

getDepth

public int getDepth()

Returns the depth of this row in the hierarchy where the root is 0. For components that do not contain hierarchical data, this method returns 1.

Overrides:

getDepth in class ComponentAdapter

Returns:

the depth for this adapter

isLeaf

public boolean isLeaf()

Returns true if the cell identified by this adapter is a leaf node. Otherwise, it returns false. For components that do not support hierarchical data, this method always returns true because the cells in such components can never have children.

Overrides:

isLeaf in class ComponentAdapter

Returns:

true if the cell identified by this adapter is a leaf node; Otherwise, return false

isHierarchical

public boolean isHierarchical()

Description copied from class: ComponentAdapter

Returns true if the cell identified by this adapter displays the hierarchical node. Otherwise, it returns false. For components that do not support hierarchical data, this method always returns false because the cells in such components can never have children.

Overrides:

isHierarchical in class ComponentAdapter

Returns:

true if the cell identified by this adapter displays hierarchical nodes; false otherwise

getFilteredStringAt

public String getFilteredStringAt(int row,
                                  int column)

Returns the String representation of the filtered value of the cell identified by the row in view coordinate and the column in model coordinates.

Note: the asymetry of the coordinates is intentional - clients like Highlighters are interested in view values but might need to access non-visible columns for testing. While it is possible to access row coordinates different from the current (that is this.row) it is not safe to do so for row > this.row because the adapter doesn't allow to query the count of visible rows.

This implementation messages the StringValue.TO_STRING with the filteredValue, subclasses should re-implement and use the api appropriate for the target component type.

PENDING JW: what about null cell values? StringValue has a contract to return a empty string then, would that be okay here as well?

PENDING JW: this is implemented to duplicate this table's lookup code if the column is not visible. That's not good enough if subclasses implemented a different strategy! We do it anyway for now, mostly we will be lucky and improve the situation against using toString always.

Overridden to fix #821-swingx: string rep of hierarchical column incorrect. In this case we must delegate to the tree directly if hidden, the visible is handled by the TreeTable itself.

PENDING JW: revisit once we switch to really using a table renderer.

Overrides:

getFilteredStringAt in class JXTable.TableAdapter

Parameters:

row - the row of the cell in view coordinates

column - the column of the cell in model coordinates.

Returns:

the String representation of the filtered value of the cell identified by the row in view coordinate and the column in model coordiantes

getStringAt

public String getStringAt(int row,
                          int column)

Returns the String representation of the value of the cell identified by the row specified row and column in model coordinates.

This implementation messages the StringValue.TO_STRING with the valueAt, subclasses should re-implement and use the api appropriate for the target component type.

PENDING JW: this is implemented to duplicate this table's lookup code if either the row or the column is not visible. That's not good enough if subclasses implemented a different strategy! We do it anyway for now, mostly we will be lucky and improve the situation against using toString always.

Overridden to fix #821-swingx: string rep of hierarchical column incorrect. In this case we must delegate to the tree directly if hidden, the visible is handled by the TreeTable itself.

PENDING JW: revisit once we switch to really using a table renderer.

Overrides:

getStringAt in class JXTable.TableAdapter

Parameters:

row - in model coordinates

column - in model coordinates

Returns:

the value of the target component's cell identified by the specified row and column
