A container widget that represents a cell in a table.
A WTable provides a table of WTableCell container widgets. A WTableCell may overspan more than one grid location in the table, by specifying a rowSpan and columnSpan . Table cells at overspanned positions are hidden. You cannot directly create a WTableCell, instead, they are created automatically by a table.
A WTableCell acts as any other WContainerWidget, except that both the vertical and horizontal alignment of contents may be specified by setContentAlignment().
The widget corresponds to the HTML <td> or <th> tag, depending on whether the cell is a plain cell or a header cell. The widget does not provide styling, and can be styled using inline or external CSS as appropriate.
| int Wt::WTableCell::columnSpan | ( | ) | const |
Returns the column span.
|
virtual |
Returns whether the widget is visible.
A widget is visible if it is not hidden, and none of its ancestors are hidden. This method returns the true visibility, while isHidden() returns whether a widget has been explicitly hidden.
Note that a widget may be at the same time not hidden, and not visible, in case one of its ancestors was hidden.
Reimplemented from Wt::WWebWidget.
| int Wt::WTableCell::rowSpan | ( | ) | const |
Returns the row span.
| void Wt::WTableCell::setColumnSpan | ( | int | colSpan | ) |
Sets the column span.
The column span indicates how many table columns this WTableCell overspans. By default, a WTableCell has a column span of 1, only occupying its own grid cell. A column span greater than 1 indicates that table cells to the right of this one are overspanned.
| void Wt::WTableCell::setRowSpan | ( | int | rowSpan | ) |
Sets the row span.
The row span indicates how many table rows this WTableCell overspans. By default, a WTableCell has a row span of 1, only occupying its own grid cell. A row span greater than 1 indicates that table cells below this one are overspanned.
