BiGridColumn

This class is used to describe columns for BiGrid and BiTree.

This class extends BiObject and therefore all methods and fields available for BiObject are also available for BiGridColumn .

Constructor

new BiGridColumn ( [ sName ] )

Parameters

Name	Type	Optional	Default	Descripton
sName	String		Untitled	This is used for the text to to show on the header cell for the column

Properties

Name	Type	get	set	Descripton
align	String			The alignment of the content inside the column.
columnIndex	Number			The index of the column in the grid columns collection. This is not neccessarily the same as the display order.
grid	BiAbstractGrid			The grid that the column is used in.
header	BiGridHeader			This is the header represenging the column in the grid.
iconColumn	Number			Whether the current column is the icon column in the grid.
indentColumn	Number			Whether the current column is the indent column in the grid. This is ignored when using the columns for a non tree.
name	String			The name of the column. This is the same as the text shown on the header.
orderIndex	Number			The index of the column as it is currently being displayed. This means that the left most column has an order index of 0. This is not necessarily the same as the columnIndex when the columns have been reordered.
sortFunction	Function			This returns the function used to compare two grid rows. This means that this should return a function that takes two arguments and returns a number (just like the normal comparison function used when sorting arrays in JavaScript).
sortType	String			The type of the data in the column. This is used to decide how to sort the data in the column. Built in support for the following types: string caseInsensitiveString number date - Uses the native JS Date type To get better control over the sorting create a subclass that overrides the sortFunction getter.
tree	BiAbstractGrid			The grid that the column is used in. (Same as grid.)
width	Number			The width of the column.
visible	Boolean			Whether the column is visible or not.

Static Methods

Name	Description
caseInsensitiveStringCompare	A function taking two strings and returns a number used to compare them (less than zero if first is smaller, zero if equal and otherwise larger than zero). This comparison is case insensitive.
dateCompare	A function taking two Date objects and returns a number used to compare them (less than zero if first is smaller, zero if equal and otherwise larger than zero).
lessThanCompare	A function taking two objects and uses the built in less than operator to compare them and returns a number (less than zero if first is smaller, zero if equal and otherwise larger than zero).
numberCompare	A function taking two number arguments and returns a number used to compare them (less than zero if first is smaller, zero if equal and otherwise larger than zero).
stringCompare	A function taking two strings and returns a number used to compare them (less than zero if first is smaller, zero if equal and otherwise larger than zero).
