BiGridHeaders

This class represents the headers for a BiGrid or a tree. The headers contain several header cells.

This class extends BiComponent and therefore all methods and fields available for BiComponent are also available for BiGridHeaders .

Constructor

new BiGridHeaders ( )

Parameters

No parameters.

Properties

Name	Type	get	set	Descripton
ascending	Boolean			If this is true then the sorting should be done ascending, if false descending and if null no sort. This is also reflected on the ascending property for the BiGridHeader this applies to.
columnCount	Number			The number of columns in the header
columnOrders	Number[]			The order in which the cell headers should be displayed in. A value of [2,0,1] means that the third cell comes first, then comes the first cell and last the second.
columnWidths	Number[]			The widths of the cell headers in the headers
filler	BiGridHeaderFiller			Returns the header acting as the filler. This is the part that is shown after the last column if the grid is wider than all the columns combined.
fitColumnWidths	Boolean			When this is true the column widths are distributed so that the fill the width of the grid
sortColumn	Number			The index of the column that should show the sort arrow.

Methods

None.

Events

Name	Type	Bubbles	Descripton
ascendingchanged	BiEvent		Fired when the ascending property changes. This happens when either the user clicks on a column header cell that is already sorted or this property is changed through script. Note that if the ascending property changed due to a change of the sortColumn this event is not fired. This is by design to prevent preformance issues.
columnorderschanged	BiEvent		Fired when the column orders are changed. This happens when either the user has reordered the columns or the order is changed through script.
columnwidthschanged	BiEvent		Fired when the column widths are changed. This happens when either the user has finished resized a column or the column widths are changed through script.
columnwidthschanging	BiEvent		Fired when the column widths are changing. This happens when the user is resizing a column.
sortcolumnchanged	BiEvent		Fired when the sort column is changed. This happens when either the user has clicks on a sortable column or the sort column is changed through script. Note that when the user clicks on the currently sorted column this event is not fired. Instead the ascendingchanged event is triggered because the sorting is changed from ascending to descending or the other way around.

Static Methods

None.

Static Fields

None.

Remarks

When working with grids there is no need to manually use this class.
