The animation framework aims to provide an easy way for creating animated and
|
||||
smooth GUI's. By animating Qt properties, the framework provides great freedom
|
||||
for animating widgets and other QObjects. The framework can also be used with
|
||||
the Graphics View framework.
|
||||
|
||||
|
||||
Documentation for these examples can be found via the Examples
|
||||
link in the main Qt documentation.
