Constructor Detail

TableHeader

public TableHeader()

Creates a table header.

Method Detail

getDefaultRenderer

public TableCellRenderer getDefaultRenderer()

Returns the default cell renderer.

Returns:

The default cell renderer.

getHeight

public int getHeight()

Returns the height of the table header.

Returns:

The height of the table header. The units of this value are specified by the underlying table's HeightUnits property.

getRenderedComponent

public Component getRenderedComponent(int column)

Returns the contents of the header cell at the specified column. This method should be used only by the rendering peer. This method will not return correct information prior to validation.

Parameters:

column - The column of the rendered header cell component to return.

Returns:

The header component.

getTable

public Table getTable()

Returns the table component with which this TableHeader is associated.

Returns:

The table component with which this TableHeader is associated.

invalidate

public void invalidate()

Marks the table header as needing to be re-rendered.

setDefaultRenderer

public void setDefaultRenderer(TableCellRenderer defaultRenderer)

Sets the default cell renderer that will be used if a column does not have an assigned renderer.

Parameters:

defaultRenderer - The new default renderer.

setTable

public void setTable(Table newValue)

Sets the table component with which this TableHeader is associated.

Parameters:

newValue - The table component with which this TableHeader is associated.

setHeight

public void setHeight(int newValue)

Sets the height of the table header.

Parameters:

newValue - The new height of the table header. The units of this value are specified by the underlying table's HeightUnits property.

validate

public void validate()

Updates the Table component to reflect its model.

Specified by:

validate in interface Component

Overrides:

validate in class AbstractComponent
