Clutter discussion (2): clutter and GTK +

Embedding:

You cannot embed GTK + widgets in it. It is a toolkit of low level, so it cannot be embedded with widgets of height level, such as GTK +. However, the clutter widget can be embedded in GTK +.

 

Usage:

Clutter can provide text (editable), but cannot provide buttons, list, combox, scroll, etc. If needed, you can embed GTK +. These components are less likely to be used in small-screen handheld devices. clutter provides the mouse push and buttons in the stage or actor (the left and right keys are not distinguished, And the touch screen does not distinguish between the left and right keys), release, enter, and exit.
