Tagasi [[ITI0011]] lehele.

== Üldine ==

Praktikum: 30.10.2014 kell 14:00

Teemad:
* JavaFX
* JavaFX klassi arvutites
** https://courses.cs.ttu.ee/pages/ITI0011:JavaFX#JavaFX_kasutamine_Java_versioon_1.7-ga
* Layout, Pane
* Shapes
* mouse event

== Koodinäite ==

== Exercise ==

Create an application which allows the user to draw a rectangle. There are several options how to achieve this:
* using mouse dragging: the starting point is fixed when the dragging starts (mouse press), the opposite corner moves along while dragging. if the dragging ends, the rectangle is fixed.
* using clicking: when clicking first time, one point is fixed, when clicking another time, the opposite corner is fixed (and rectangle is drawn).
* some other way

Optional requirements:
* more than one rectangle can be drawn
