Class DataColumn

Known Direct Subclasses:
DataColumnBoolean, DataColumnDouble, DataColumnIconSize, DataColumnInt, DataColumnLong, DataColumnObject, DataColumnPixbuf, DataColumnStockItem, DataColumnString

public abstract class DataColumn
extends java.lang.Object

Represents a block in which data can be stored in a TreeModel (such as ListStore or TreeStore). In Gtk, these are called columns and are referenced by integers. We have renamed them to DataBlocks to avoid confusion with TreeViewColumns and created these objects to use rather than integers. This allows type checking and should make programs more maintainable. This is an abstract class - there is an implementation of it for each type of data accepted by the two tree models.

Method Summary

boolean
equals(DataColumn col)
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
int
getColumn()
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.
Type
getType()
Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Method Details

equals

public boolean equals(DataColumn col)

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Determine if the given DataColumn represents the same column in the store as the current object. This compares the column ids using the getColumn() method.

getColumn

public int getColumn()

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Returns the column number of this dataBlock used internally by Gtk.

getType

public Type getType()

Deprecated. Superceeded by java-gnome 4.0; a method along these lines may well exist in the new bindings, but if it does it likely has a different name or signature due to the shift to an algorithmic mapping of the underlying native libraries.

Returns the glib Type of data contained in this column. This can only be called once. (it is only needed once - in the constructor of the listStore/TreeStore)
