QgsProjectionSelectionWidget select no projection issue in PyQt5

I am trying to override the original (invalid projection) value in the mqgsprojectionselectionwidget to no projection selected, but I don't know what functions would be needed! I am using pyqt5 to display plugin in QGIS 3.0

Hi
I think its better to ask in QGIS forum.
QGIS is not part of Qt so you have to have huge luck that someone knows the answer here.

Okay, thanks for the reply

So I managed to figure it out using the c++ source file for QgsProjectionSelectionWidget(https://qgis.org/api/qgsprojectionselectionwidget_8cpp_source.html)

mQgsProjectionSelectionWidget.setOptionVisible(mQgsProjectionSelectionWidget.CrsNotSet,True)

#Sets whether a predefined CRS option should be shown in the widget.

mQgsProjectionSelectionWidget.setNotSetText('Use default projection')

#Sets the text to show for the not set option. Note that this option is not shown by default and must be set visible by calling setOptionVisible().
