<br><br></div><div>I propose to remove the unmaintained support for PythonQt full wrapping and optimize the existing light wrapping.<br><br><br></div><div>If you never build CTK with wrapping enabled, you can archive this email. The proposed changes won't impact your existing projects. <br>
</div><div><br><br></div><div>Details<br>--------<br></div><div><br></div>Currently, there is a build option named "CTK_ENABLE_Python_Wrapping" allowing to enable the automatic wrapping of CTK classes and also expose the tool to "wrap" classes within your application.<br>
<br><br></div>The wrapping exists in two flavors:<br><br></div> * Light wrapping (the default)<br></div> * Full wrapping<br><br><br></div>Light wrapping: This basically check that Qt classes derives from QObject and then create "PythonQtDecorator" allowing to instantiate/delete your classes.<br>
<br></div>Full wrapping: Attempt to make automatic use of the PythonQtGenerator (used to also wrap Qt for PythonQt). <br><br><br><br></div>Proposed changes:<br>------------------------<br><br><div><div><div><div><div><div>
<div> - Removal of option related to "Full" wrapping. This never really worked. It would require us to maintain our set of "xml" files describing CTK classes. See [3] for an examples. Later one, we could also look at PySide[4] and see how it could be supported.<br>
<br></div><div> - Simplification and optimization of the existing "Light" wrapping. In project like Slicer where there is a lot of library to "light wrap" .. the CMake configuration time is considerably impacted.<br>
