java.lang.Object

org.uberfire.ext.wires.core.grids.client.widget.grid.impl.DefaultGridWidgetCollapsedCellMouseEventHandler

All Implemented Interfaces:

NodeMouseEventHandler

public class DefaultGridWidgetCollapsedCellMouseEventHandler
extends Object
implements NodeMouseEventHandler

A NodeMouseEventHandler to handle interaction with a "merged" GridCell "hot spot". The AbstractNodeMouseEvent is checked to have happened over the GridWidget.onGroupingToggle(double, double, double, double) in which case the applicable GridRow(s) are either collapsed or expanded; depending on their state.

                                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.

handleBodyCell

public boolean handleBodyCell(GridWidget gridWidget,
                              com.ait.lienzo.client.core.types.Point2D relativeLocation,
                              int uiRowIndex,
                              int uiColumnIndex,
                              com.ait.lienzo.client.core.event.AbstractNodeMouseEvent event)

Description copied from interface: NodeMouseEventHandler

Handles the event for a Body element.

Specified by:

handleBodyCell in interface NodeMouseEventHandler

Parameters:

gridWidget - The GridWidget on which the event occurred.

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

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.
