Obsolete Code Removal

This section documents suggested code changes after removing support for a particular features. Each category has a short description, code snippets, a suggested upgrade path, and references to relevant commits.

Qt>=5.0.0: QDesignerCustomWidgetInterface header include and Q_PLUGIN_METADATA macro

Before: 

  #include <QtGlobal>
  #if(QT_VERSION < QT_VERSION_CHECKS(5, 0, 0))
  #include <QDesignerCustomWidgetInterface>
  #else
  #include <QtUiPlugin/QDesignerCustomWidgetInterface>
  #endif

  class Q_SLICER_MODULE_SEGMENTATIONS_WIDGETS_PLUGINS_EXPORT qSlicerSegmentationsModuleWidgetsAbstractPlugin
      : public QDesignerCustomWidgetInterface
  {
  #if (QT_VERSION >= QT_VERSION_CHECK(5, 0, 0))
    Q_PLUGIN_METADATA(IID "org.qt-project.Qt.QDesignerCustomWidgetInterface")
  #endif
    Q_INTERFACES(QDesignerCustomWidgetInterface);
  }
<pre>

After:

<pre>
  #include <QtUiPlugin/QDesignerCustomWidgetInterface>

  [...]

  class Q_SLICER_MODULE_SEGMENTATIONS_WIDGETS_PLUGINS_EXPORT qSlicerSegmentationsModuleWidgetsAbstractPlugin
      : public QDesignerCustomWidgetInterface
  {
    Q_PLUGIN_METADATA(IID "org.qt-project.Qt.QDesignerCustomWidgetInterface")
    Q_INTERFACES(QDesignerCustomWidgetInterface);
  }

Qt>=5.0.0: Python: Simpler use of setSectionResizeMode

This migration guide points becomes obsolete: Documentation/Nightly/Developers/Tutorials/MigrationGuide#Qt5:_Fix_error:_.E2.80.98class_QHeaderView.E2.80.99_has_no_member_named_.E2.80.98setResizeMode.E2.80.99

Before: 

 _setSectionResizeMode(self.horizontalHeader(), 0, qt.QHeaderView.Stretch)
 def _setSectionResizeMode(header, *args, **kwargs):
   if version.parse(qt.Qt.qVersion()) < version.parse("5.0.0"):
     header.setResizeMode(*args, **kwargs)
   else:
     header.setSectionResizeMode(*args, **kwargs)

After: 

 self.horizontalHeader(0, qt.QHeaderView.Stretch)
