getName in class ColumnProxy
Returns:
the column name.

getPreferredSize

public Dimension getPreferredSize(Visualization vis)
Computes and return the preferred size for this layout and this visualization.

Specified by:
getPreferredSize in interface Layout
Parameters:
vis - the visualization
Returns:
the preferred size for this layout and this visualization.

getColumn

public Column getColumn()
Returns the visualized column.

Returns:
the visualized column.

setColumn

public boolean setColumn(Column column)
Sets the visualized column.

Parameters:
column - the column
