Fix Qt 6.8 warnings #1074

Open Vekhir opened 1 month ago

Vekhir commented 1 month ago

In the upcoming Qt 6.8 release, several deprecations and changes are made. In preparation for that, this PR resolves the emitted warnings when building with Qt 6.8 Beta 3.

Except for the new permissions system introduced in 6.8, the changes modernise the current code and adopt current best practices.

The permissions system changes how Qt handles permission requests from websites. Most importantly, it saves the permissions itself, so we don't have to. Tested with permission.site. All new code is enclosed in preprocessor directives, as is the old permission management, to remove it with Qt 6.8+.

Builds fine with Qt 6.7.2, Qt 6.8 Beta 3, Qt 5.15.14.
