To my knowledge, this is the way to go. 

Unfortunately, the Qt 4/5 interfaces to the various window managers are 
lacking (in part due to the attempt to unify the differences of the many 
supported OS). Using other advertized window flags result more often than not 
in missing/dissatisfying behavior. 

Additionally, the many existing X window manager implementations do contribute 
to the imperfection, because they all interpret 



Depending on your target OS(es), that you forgot to mention, you might need to 
combine your approach with low level OS and WM dependent code (e.g. for sticky 
windows), that could be realized with e.g. xcffib on X. But be warned, that is 
an "iceberg" can of worms and a testing nightmare...
