Detailed Description

A table column.

A WTableColumn is returned by WTable::columnAt() and managing various properties of a single column in a table (it is however not a widget).

A table column corresponds to the HTML <col> tag.

Constructor & Destructor Documentation

◆ WTableColumn()

Wt::WTableColumn::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().

Member Function Documentation

◆ columnNum()

int Wt::WTableColumn::columnNum ( ) const

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::columnAt()

◆ elementAt()

WTableCell * Wt::WTableColumn::elementAt ( int row )

Access the column element at the given row.

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

The column must be inserted within a table first.

◆ id()

const std::string Wt::WTableColumn::id ( ) const

virtual

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 composite widget 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(). The auto-generated id is created by concatenating objectName() with a unique number.
