*: normalize usage of layouts before, I used them two ways, once was by setting the layout later by using setLayout(QWidget), and the other was just using the constructor. I find the constructor to be easier to read, so I chose that one.

<transition source="idle" target="run">
	<event name="key_up|key_shift" />
</transition>
<transition source="run" target="attack">
	<event name="key_ctrl" />
	<condition expr="weapon != null" />
</transition>
