Method Detail

getBestVSColumnHeaderValueType

public Value.Type getBestVSColumnHeaderValueType(VSRelativeReference<?> reference)

Requests the value type that would best suit the listener.

Specified by:

getBestVSColumnHeaderValueType in interface IVSColumnBestValueListener

Parameters:

reference - The VSRelativeReference instance holding the reference.

Returns:

null if none is available.

onResolved

public void onResolved(VSRelativeReference<?> reference,
                       VSColumnHeader column)

Called when the property reference has been resolved. UI components use this method to set its state according to the field.

Specified by:

onResolved in interface IVSColumnListener

Parameters:

reference - The VSRelativeReference instance holding the reference.

column - The target reference.

onBroken

public void onBroken(VSRelativeReference<?> reference,
                     VSColumnHeader column)

Called when the property reference has been broken, i.e. unresolved.

Specified by:

onBroken in interface IVSColumnListener

Parameters:

reference - The VSRelativeReference instance holding the reference.

column - The target reference.

onStateChanged

public void onStateChanged(VSColumnHeader table,
                           IVSComponentState.State state,
                           boolean on)

Called when the table changes state.

Specified by:

onStateChanged in interface IVSColumnListener

Parameters:

table - The VS table.

state - The state change.

on - New state.

onParentStateChanged

public void onParentStateChanged(IVSComponent parent,
                                 IVSComponentState.State state,
                                 boolean on)

Called when the column changes state.

Specified by:

onParentStateChanged in interface IVSComponentListener

Parameters:

parent - The parent who's state was changed.

state - The state change, possible values PARENT_ENABLED, PARENT_READONLY, PARENT_VISIBLE.

on - New state.

onSingleSelectionChanged

public void onSingleSelectionChanged(VSColumnHeader column,
                                     int rowIndex)

Called when the row selection in table single-selection mode is changed to forward to column listeners.

Specified by:

onSingleSelectionChanged in interface IVSColumnListener

Parameters:

column - The column.

rowIndex - The row index selected, -1 for none.
