Potentially, this should be fixed with #440
On the toolbar3d branch I was exploring a dataset then I clicked probably letf or centre click with a modifier. The whole thing crashed with the following error:
>>> v.startRenderLoop()
QWidget: Must construct a QApplication before a QWidget
I did not have any Qt application running, nor should an interaction with the viewer spawn a QWidget.
Code to reproduce (requires a META image file, like https://github.com/TomographicImaging/CIL-Data/raw/refs/heads/main/head.mha), plus (furiously) click.
reader = vtk.MetaImageReader()
reader.SetFileName('myfilename.mha')
reader.Update()
from ccpi.viewer import viewer2D
v = viewer2D()
v.setInputData(reader.GetOutput())
v.startRenderLoop()
