Method Detail

getHandle

public Handle getHandle()

Get the handle of the object.

Get a DataColumn object representing the currently sorted column. This is not the same DataColumn used to create the store. It is only of type DataColumn (not DataColumnString, etc). It can be compared with another DataColumn object using the DataColumn method.

Returns: A DataColumn object representing the currently sorted column or null if the is no column currently sorted.

getSortOrder

public SortType getSortOrder()

Get the current sorting order of the store.

Returns: A SortType object defining the current sorting order of the store or null if there is no current sort order.

handleCompareFunc

public int handleCompareFunc(Handle model, Handle aIter, Handle bIter, int col)

Call-back method invoked by the JNI code when sorting is required. For internal use only.

setSortColumn

public void setSortColumn(DataColumn column, SortType order)

Set the column in the model to sort on.

setSortMethod

public void setSortMethod(TreeIterComparison method, DataColumn column)

Set the class used to sort the list according to the values stored in the given DataColumn.
