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.

WTable, WTableRow

Constructor & Destructor Documentation

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

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()
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.

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.

See also
WWidget::jsRef()

Reimplemented from Wt::WObject.

void Wt::WTableColumn::setId ( const std::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::id()
void Wt::WTableColumn::setStyleClass ( const WString style)

Sets the CSS style class for this column.

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

See also
styleClass(), WWidget::setStyleClass()
void Wt::WTableColumn::setWidth ( const WLength width)

Sets the column width.

The default column width is WLength::Auto.

See also
width(), WWidget::resize()
const WString& Wt::WTableColumn::styleClass ( ) const

Returns the CSS style class for this column.

See also
styleClass(), WWidget::styleClass()
WTable* Wt::WTableColumn::table ( ) const

Returns the table to which this column belongs.

See also
WTable::rowAt()
WLength Wt::WTableColumn::width ( ) const

Returns the column width.

See also
setWidth(const WLength&)
