[Gambas-user] Dinamic lines

[tobias]

hi,

>> How to draw a line
>> How to draw a text
>> How to do it on a printer
>> How to do it on a canvas
>> How to make lines removable

imho, one should be able to figure some of these things out using the doc.
i never worked with printer, but answers to 1 and 2 are just where 
everyone expects them:

i don't know what "canvas" is. i'm not a native english speaker and my 
dictionary gave me nothing programming related...

i don't think that lines can be made "removable" because you would have 
to have an object for them, i think. this would be waste of ram in my 
opinion and if you draw with a pencil on a paper, you don't create new 
objects that you can remove if you want to, right? :)
you have to use an eraser:
you can implement that by yourself saving source and destination coords 
of every line and if requested draw another line over it with your 
background's color... just a thought.
