                                com.ait.lienzo.client.core.event.AbstractNodeMouseEvent event)

Description copied from interface: NodeMouseEventHandler

Executes when a NodeMouseEventHandler reacts to the AbstractNodeMouseEvent to which the NodeMouseEventHandler has been registered. Note uiHeaderRowIndex, uiHeaderColumnIndex, uiRowIndex and uiColumnIndex may be Optional.empty() if the event did not occur over the applicable element within the GridWidget.

Specified by:

onNodeMouseEvent in interface NodeMouseEventHandler

Parameters:

gridWidget - The GridWidget on which the event occurred.

relativeLocation - Point2D relative to the top-left of the GridWidget

uiHeaderRowIndex - Index of the Header row as seen in the UI. 0-based index. Top row is 0.

uiHeaderColumnIndex - Index of the Header column as seen in the UI. 0-based index. Leftmost column is 0.

uiRowIndex - Index of the Body row as seen in the UI

uiColumnIndex - Index of the Body column as seen in the UI

event - The original event.

Returns:

true if the event was handled.

handleHeaderCell

public boolean handleHeaderCell(GridWidget gridWidget,
                                com.ait.lienzo.client.core.types.Point2D relativeLocation,
                                int uiHeaderRowIndex,
                                int uiHeaderColumnIndex,
                                com.ait.lienzo.client.core.event.AbstractNodeMouseEvent event)

Checks if the AbstractNodeMouseEvent happened on a "linked" GridColumn. If the AbstractNodeMouseEvent was found to have happened on a GridWidget "linked" column then selection of the "linked" GridColumn is delegated to GridSelectionManager.selectLinkedColumn(GridColumn).

Specified by:

handleHeaderCell in interface NodeMouseEventHandler

Parameters:

gridWidget - The GridWidget on which the event occurred.

relativeLocation - Point2D relative to the top-left of the GridWidget

uiHeaderRowIndex - Index of the Header row as seen in the UI. 0-based index. Top row is 0.

uiHeaderColumnIndex - Index of the Header column as seen in the UI. 0-based index. Leftmost column is 0.

event - The original event.

Returns:

true if the event was handled.
