Member Function Documentation

virtual void SensorEditor::onCurrentRecordChange

(

int

row

)

[inline, protected, virtual]

Reimplemented from MappedBaseEditor.

                                               {
        MappedBaseEditor::onCurrentRecordChange(row);
        updateSensorChannelView();
    }

virtual void SensorEditor::onQueryChange

(

)

[inline, protected, virtual]

This function is primarily due to a bug in Qt where the mappers indexes become invalid after Model::select() is called, which also emits queryChanged(). cf. http://bugreports.qt.nokia.com/browse/QTBUG-1086 One consequence of this is that mapper->currentIndex() == -1 so it can not be used as currentIndex.

Todo:

Check whether MappedBaseEditor::onQueryChange() is still required. If not, delete.

Reimplemented from MappedBaseEditor.

                                {
        MappedBaseEditor::onQueryChange();
        updateSensorChannelView();
    }

virtual void SensorEditor::updateButtons

(

)

[inline, protected, virtual]

Reimplemented from MappedBaseEditor.

Referenced by SensorEditor().

                                {
        MappedBaseEditor::updateButtons();
        channelView->setDisabled(isCurrentRecordNew() || model()->rowCount() == 0);
    }
