Because it is not QT :).

TreeView was designed to hold and show lot of data from TreeModel. If
each cell was represented as widget it could increase CPU usage
dramatically and slow down the View.

So, you must to draw the widget "from scratch" using cell area. There is
no other way.

The states and flags I am checking is used to draw my cell properly -
selected, checked/toggled, etc.

See GTK sources.
