Constructor Details

WTableColumn

public WTableColumn()

Creates a new table column.

Table columns must be added to a table using WTable#insertColumn() before you can access contents in it using elementAt().

Method Details

getTable

public WTable getTable()

Returns the table to which this column belongs.

See Also:

• WTable.getRowAt(int row)

elementAt

public WTableCell elementAt(int row)

Access the column element at the given row.

Like WTable#getElementAt(), if the row is beyond the current table dimensions, then the table is expanded automatically.

The column must be inserted within a table first.

getColumnNum

public int getColumnNum()

Returns the column number of this column in the table.

Returns -1 if the column is not yet part of a table.

See Also:

• WTable.getColumnAt(int column)

setWidth

public void setWidth(WLength width)

Sets the column width.

The default column width is WLength.Auto.

See Also:

• getWidth()
• WWidget.resize(WLength width, WLength height)

getWidth

public WLength getWidth()

Returns the column width.

See Also:

• setWidth(WLength width)

setStyleClass

public void setStyleClass(String style)

Sets the CSS style class for this column.

The style is inherited by all table cells in this column.

See Also:

• getStyleClass()
• WWidget.setStyleClass(String styleClass)

getStyleClass

public String getStyleClass()

Returns the CSS style class for this column.

See Also:

• getStyleClass()
• WWidget.getStyleClass()

setId

public void setId(String id)

Sets the CSS Id.

Sets a custom Id. Note that the Id must be unique across the whole widget tree, can only be set right after construction and cannot be changed.

See Also:

• WObject.getId()

getId

public String getId()

Description copied from class: WObject

Returns the (unique) identifier for this object

For a WWidget, this corresponds to the id of the DOM element that represents the widget. This is not entirely unique, since a WCompositeWidget shares the same id as its implementation.

By default, the id is auto-generated, unless a custom id is set for a widget using WWidget.setId(String). The auto-generated id is created by concatenating WObject.getObjectName() with a unique number.

Overrides:
