QwtPlotItem to emit a new signal when legend has changed #62

Closed CEAVirginie closed 11 months ago

emit a Signal if legend changed (QwtPlotItem must derive from QObject)

PierreRaybaut commented 3 years ago

Two things are bothering me for this one:

  1. QwtPlotItem object does not inherit from QObject as of today because it was designed to be a neutral object with respect to Qt.
  2. There is already a signal emitted in this situation: QwtPlot.legendDataChanged. So, providing a minor change of implementation in the code using PythonQwt, this use case is already covered by PythonQwt
