PivotUIEvent

PivotUIEvent is fired when user operates on the Pivottable. This event class covers the following types of Events: onPivotNodeOpen, onPivotPopup, onPivotTooltip, onPivotContext.

The effective regions where the event will occur are column area, row area, and data area. In other words, activities in title cells do not trigger this event.

onPivotNodeOpen

This event is fired when user clicks on the open/close icon of a header node rows or columns.

onPivotPopup (left click)

This event is fired when user left-clicks on a cell.

• If this event is not listened, the event will not be fired.

For example,

<pivottable model=""${model} onPivotPopup='alert("Pivot Popup!")' />

onPivotTooltip (mouse over)

This event is fired when user's cursor hovers on a cell.

• If this event is not listened, the event will not be fired.

For example,

<pivottable model=""${model} onPivotTooltip='label.value = "(" + event.x + ", " + event.y + ")"' />
<label id="label" />

Note: this event will be fired whenever you move cursor to a new cell. You can listen to the event on client side to save bandwidth.

onPivotContext (right click)

This event is fired when user right-clicks on a cell.

• If this event is not listened, the event will not be fired.

For example,

<pivottable model=""${model} onPivotContext='menupopup.open(self, "at_pointer")' />
<menupopup id="menupopup">
	<menuitem label="My Menuitem" />
</menupopup>

Information provided by PivotUIEvent

PivotUIEvent provides the following information:

• The area in which the event occurs (data area, row area, or column area)
• Data field on which the event occurs (null if not applicable)
• Header node and subtotal on which the event occurs, for both row and column
• The row and column indices on which the event occurs
• Cursor coordinate relative to Pivottable component.

public void onPivotPopup$pivot(PivotUIEvent event) {
	int fieldType = event.getFieldType(); // area
	PivotField dataField = event.getDataField(); // data field
	PivotHeaderContext rowContext = event.getRowContext(); // row information
	PivotHeaderContext colContext = event.getColumnContext(); // column information
	int mouseX = event.getX(); // cursor x-coordinate
	int mouseY = event.getY(); // cursor y-coordinate
}

PivotHeaderContext

PivotHeaderContext represents a specific column or row in a Pivottable. It consists of three variables: header node, subtotal calculator, and displayed index.

• Header node refers to the PivotHeaderNode it belongs to.
• Subtotal calculator refers to the Calculator it corresponds to. If the column or row does not represent a subtotal, it will be null.
• Displayed index refers to the actual index shown in the table. The origin (0, 0) is defined to be the first data cell (the upper-left-most one).
