- initialization: if a threaded, the fit must not be enabled
- when changing the profile type setReadOnly for the fit and class according to if threaded or not
- when changing if threaded or not, setReadOnly accordingly for the fit and class
as described in https://forum.freecadweb.org/viewtopic.php?f=3&t=50611, the task dialog should just read out the parameters on initialization and not invoke automatically change actions.
This PR also fixes a bug that opening a document with a cheesehead hole leads to an error about an invalid index. The reason is that we access the hole cut type before we set its enums. Thus initialize the cut type with all possible enums since, if necessary, the reduced enum set will be set later on parsing the file.
+ do not rely on translated strings but set user data for the items of the combo box
+ do not use tr() to convert the C strings to QString of the hole feature, use QString::fromLatin1
+ do not use findText() twice for the same search but store the result
as mentioned in https://forum.freecadweb.org/viewtopic.php?f=13&t=47584&start=10#p433116
a typical use case is that one changes the hole type from e.g. ISO normal to ISO fine. The size should however be the same.
This PR enables this and also takes care for the thread class and cut type, see the attached screencast.
