Static Public Member Functions inherited from Wt::WWidget | |
static WString | tr (const char *key) |
Short hand for WString::tr() | |
A specialized tree node which allows additional data to be associated with each node.
Additional data for each column can be set using setColumnWidget().
Wt::WTreeTableNode::WTreeTableNode | ( | const WString & | labelText, |
std::unique_ptr< WIconPair > | labelIcon = nullptr |
||
) |
Creates a new tree table node.
Returns the widget set for a column.
Returns the widget set previously using setColumnWidget(), or 0
if no widget was previously set.
Sets a widget to be displayed in the given column for this node.
Columns are counted starting from 0 for the tree list itself, and 1 for the first additional column.
The node label (in column 0) is not considered a column widget. To set a custom widget in column 0, you can add a widget to the labelArea().

protectedvirtual |
Sets the table for this node.
This method is called when the node is inserted, directly, or indirectly into a table.
You may want to reimplement this method if you wish to customize the behaviour of the node depending on table properties. For example to only associate data with the node when the tree list is actually used inside a table.
WTreeTable * Wt::WTreeTableNode::table | ( | ) | const |
Returns the table for this node.
