This is to make it look more consistent with the open dialog, which needed Controls 2 in order to make the drop-downs work on MacOS.
As discussed in the CCB.
When importing only the models of a project file, Cura wasn't checking whether the file should
be added to the recent files list. This commit fixes that.
CURA-7996
Just whenever we need it, please.
This removes a warning from the start-up sequence, but the warning is still there when you open the dialogue. It's complaining that a model has size -13 and another has size -14, but I don't know which model that is. The UserChangesModel seems to be fine at a size of 1 or so.
Contributes to issue CURA-7501.
As discussed in the CCB this morning. Since the new profile will be the _changed to_ profile rather than the _changed from_ (the latter of which would make the button useful, but since the profile is already switched at that point it would be a lot of work), the 'Create New Profile ...' button (in the Keep/Discard dialog) is redundant, since you can always create a new profile if you select keep changes.
Gracefully handle the case where the machine manager is requested to
delete the last machine in Cura. In this case, instead of deleting
everything of this machine and still keep it as an active machine,
the machine manager will set the active machine to None.
The QML files which depend on the active machine were changed to
properly handle themselves when there is no active machine.
CURA-7454
There are multiple issues with that line:
* Other languages might have the application name before their version of 'About'. The previous line can't account for those languages because the application name is always appended at the end.
* The old one was trying to translate CuraApplication.applicationDisplayName which can't be statically determined.
* The old one had no explanation towards the translator.
The logic using just a "skip_project_file_check" boolean was too obscure
imho, so used a string value with more explicit values
to improve readability
CURA-6824
The UM.Application.platform property has been removed by someone for quite some time.
I don't know why the check was in there, but it doesn't seem needed at all as the property was always undefined
