Class zwt.ui.table.Column

A column represents all the attributes of a column in a table, such as width, resizibility, minimum and maximum widths.

The column also provides a cell renderer to display the values in the column and a cell editor to edit these values.

It stores the link between the columns in the table (the view) and the model through the modelIndex which is the column in the table model queried to get the values for the cells in the column. If the column is moved in the view the modelIndex does not change.

Defined in: Column.js.

zwt.ui.table.Column(int_modelIndex)

Construct a column.
Author: Jeremy KUHN.

Parameters:
int_modelIndex

See:: zwt.ui.table.TableModel

Method Detail

{zwt.ui.table.CellEditor} getCellEditor()

Return the editor associated to the column. A cell editor is used to edit the values in the column.

Returns:: The cell editor

{zwt.ui.table.CellRenderer} getCellRenderer()

Return the cell renderer associated to the column. A cell renderer is used to display the values in the column.

Returns:: The cell renderer

{zwt.ui.table.ColumnEventManager} getColumnEventManager()

Return the column event manager attached to the model.

Returns:: The column event manager

{String} getDescription()

Return the description of the column.

Returns:: The column description

{String} getLabel()

Return the label of the column.

Returns:: The column label

{Integer} getMaxWidth()

Return the maximum width of the column in the table. If the column is not resizable then the preferred width is returned.

Returns:: The maximum width

{Integer} getMinWidth()

Return the minimum width of the column in the table. If the column is not resizable then the preferred width is returned.

Returns:: The minimum width

{Integer} getModelIndex()

Return the corresponding model index of the column. This index indicates what column of the data model will be displayed in the table column.

Returns:: The model index

{Integer} getPreferredWidth()

Return the preferred width of the column in the Table. This value is used by the Table to determine the actual initial width of the column in the table.

Returns:: The preferred width

{Boolean} isEditable()

Determine whether the cells in the column are editable. Column is editable by default.

Returns:: true if the cells are editable, false otherwise

{Boolean} isResizable()

Determine whether the column is resizable. Column is resizable by default.

Returns:: true if the column is resizable, false otherwise
