◆ SelectionCheckFunctionType

using QmitkMultiNodeSelectionWidget::SelectionCheckFunctionType = std::function<std::string(const NodeList &)>

Helper function that is used to check the given selection for consistency. Returning an empty string assumes that everything is alright and the selection is valid. If the string is not empty, the content of the string will be used as error message in the overlay to indicate the problem.

Member Function Documentation

◆ AllowEmissionOfSelection()

bool QmitkMultiNodeSelectionWidget::AllowEmissionOfSelection ( const NodeList & emissionCandidates ) const

overrideprotectedvirtual

This function will be called before the CurrentSelectionChanged signal is emitted. The return value indicates if the signal should be emitted (true = emission; false = no emission). The default implementation always returns true.

Parameters

emissionCandidates The nodes that will be emitted if the function returns true.

Reimplemented from QmitkAbstractNodeSelectionWidget.

◆ changeEvent()

void QmitkMultiNodeSelectionWidget::changeEvent ( QEvent * event )

overrideprotected

◆ CurrentSelectionViolatesCheckFunction()

bool QmitkMultiNodeSelectionWidget::CurrentSelectionViolatesCheckFunction ( ) const

Returns if the current internal selection is violating the current check function, if set.

◆ DialogClosed

◆ OnInternalSelectionChanged()

void QmitkMultiNodeSelectionWidget::OnInternalSelectionChanged ( )

overrideprotectedvirtual

This member function will called when ever a new internal selection has been determined. This can be used to update the state of internal widgets. The default implementation does nothing.

Reimplemented from QmitkAbstractNodeSelectionWidget.

◆ SetSelectionCheckFunction()

void QmitkMultiNodeSelectionWidget::SetSelectionCheckFunction ( const SelectionCheckFunctionType & checkFunction )

A selection check function can be set. If set the widget uses this function to check the made/set selection. If the selection is valid, everything is fine. If selection is indicated as invalid, it will not be communicated by the widget (no signal emission).

◆ UpdateInfo()

void QmitkMultiNodeSelectionWidget::UpdateInfo ( )

overrideprotectedvirtual

Method is called if the display of the selected nodes should be updated (e.g. because the selection changed).

Implements QmitkAbstractNodeSelectionWidget.
