Detailed Description

Input handler retrieve all inputs from user and may change MapView (emits viewChange signal). If handler don't accept specific action, returns false. In such case, default handler for this action should be activated.

Input handlers is application of behaviour pattern. It solves problems like:

• what should happen when finger is on the screen and plus button is pressed
• recognising multitouch gestures

Qt provides api for register custom gesture recognizers, but it is not available in QML world and its api don't fit to Map application requierements.

Handler also controls map animations.
