Qt6 compatibility is broken in some cases when building with conan. This is due to the find_package version check against 5.5 rejecting the Qt6 version (e.g. 6.3.1).
This patch removed the version check.
Qt6 requires C++17 for building. ADS however only requires C++14 so far. Now when building using Conon for example the packages are built independently and ADS is built using the C++-14 flag which in turn causes the included Qt6 headers to fail the compile process. This patch bumps the required C++ standard to C++17 for builds targeting Qt6 only.
This adds a `addDockWidgetToContainer()` method to `CDockManager`, which allows a dock widget to be registered with the dock manager, and added to a specific container, even if that container doesn't currently have any `DockAreaWidget`s.
This is pretty much just a clone of `addDockWidget()`, but with the ability to specify a container widget instead of a dock area.
The main CMakeLists.txt was updated to allow explicitly setting the
version for the project by setting the `ADS_VERSION` variable (e.g.
cmake .. -DADS_VERSION=1.0.0).
The default behavior is to determine the version by reading the
information from git. Adding the option to override this variable at
configure time allows the library to be built outside of its git
repository, such as when the code is vendored directly into another
project and added using `add_subdirectory`.
This fixes a crash which could occur when restoring the state of a floating container to a non-floating container.
This was because `ads::CDockContainerWidget::RestoreState()` will unconditionally assume this is floating if the XML has the `Floating` boolean set, and will dereference `floatingWidget()`. If this isn't floating, `floatingWidget()` will return `nullptr`, leading to a crash when it's subsequently used.
Fixes#379.
This fixes a bug whereby you could close a dock widget by middle-clicking its tab, even if its `CDockWidget::DockWidgetClosable` flag is set to `false`.
