My project requires that the user of the application views and interacts with a full sketch of the plant of a specific industrial process (that includes basins, pipes, valves etc.) In short the user should be able to configure the plant according to his present case. For example when the user clicks on a valve to open it, air bubbles should be seen in a specific basin and vice versa. Drawing the sketch on the screen is not the problem. What I am concerned about is how to handle the user mouse click events & repainting the sketch the easiest way possible. What I am thinking about is how can I work around the need to write my own classes to draw the process. Instea   More>>

My project requires that the user of the application views and interacts

with a full sketch of the plant of a specific industrial process (that
includes basins, pipes, valves etc.) In short the user should be able to

configure the plant according to his present case. For example when the
user clicks on a valve to open it, air bubbles should be seen in a
specific basin and vice versa.

Drawing the sketch on the screen is not the problem. What I am concerned

about is how to handle the user mouse click events & repainting the
sketch the easiest way possible. What I am thinking about is how can I
work around the need to write my own classes to draw the process.
Instead I want to directly use box-like components to represent
rectangular basins, circular like components to represent valves etc. &
then put the necessary code for updating the sketch in the event
handlers..

I'll very much appreciate any links or information from someone who had
a similar experience.
Thanks.
