Hi

I am very new at java.
I want to understand what some functions do:
I am using SWT.

1)What (its a canvas function in SWT)


actually do? and how can i draw on it...

2)Lets suppose i have a canvas in my gui..
how would i get actions from user? for example, if he press arrow key, the function will bring some int, lets say 1 for up arrow, and 2 for down arrow key?


Thank you
