const

Returns the currently selected data node, or nullptr if none is selected.

GetSelectionIsOptional()

bool QmitkNodeSelectionButton::GetSelectionIsOptional

const

Returns whether the selection is optional.

SetNodeInfo

virtual void QmitkNodeSelectionButton::SetNodeInfo ( QString  info )

virtualslot

Sets the info text that is shown when no node is selected.

Parameters

[in]

info

The info text, which may contain HTML.

SetSelectedNode

virtual void QmitkNodeSelectionButton::SetSelectedNode ( const mitk::DataNode *  node )

virtualslot

Sets the node to display.

Parameters

[in]

node

The data node to display. May be nullptr.

SetSelectionIsOptional

void QmitkNodeSelectionButton::SetSelectionIsOptional ( bool  isOptional )

slot

Set the widget into an optional mode. Optional means that the selection of no valid node does not mean an invalid state. Thus no node is a valid "node" selection too. The state influences if the info text is handled as an information (optional) or a warning (optional==false).
