Returns the preferred height for the given row. It loops across all visible columns and returns the maximal pref height of the rendering component. Falls back to the table's base rowheight, i f there are no columns or the renderers max is zeor.

Parameters:

table - the table which provides the renderers, must not be null

row - the index of the row in view coordinates

Returns:

the preferred row height of

Throws:

NullPointerException - if table is null.

IndexOutOfBoundsException - if the row is not a valid row index

public static void setPreferredRowHeights(JTable table)

Sets preferred row heights for all visible rows.

Parameters:

table - the table to set row heights to

Throws:

NullPointerException - if no table installed.

ordinalsOf

public static int[] ordinalsOf(Enum<?>... values)

Returns an array containing the ordinals of the given values of an Enum.

Convience for clients which define TableColumns as Enums (Issue #1304-swingx).

clear

public static void clear(TableColumnModel model,
                         boolean includeHidden)

Removes all columns of the given column model. Includes hidden columns as indicated by the includesHidden flag, the flag has no effect if the model is not of type TableColumnModelExt.

Parameters:

model - the column model to remove all columns from.
