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.
| 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().
| 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.
| 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.
|
overridevirtual |
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().
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.
| 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.
| void Wt::WTableColumn::setWidth | ( | const WLength & | width | ) |
Sets the column width.
The default column width is WLength::Auto.
| const WString & Wt::WTableColumn::styleClass | ( | ) | const |
Returns the CSS style class for this column.
| WTable * Wt::WTableColumn::table | ( | ) | const |
Returns the table to which this column belongs.
| WLength Wt::WTableColumn::width | ( | ) | const |
Returns the column width.
