Hi all,
I’m pretty new to these forums and at the moment I am working on this little drawing
application. I found this source code attached and what I will produce will be based
on this. BUT…I’m just wondered is it possible to code this so that there is an UNDO
and REDO button? Lets say that I am drawing an image use this and I get ONE line wrong, it would be really useful to undo the last line drawn and thus remove it and if I click this undo button again it remove the line that I drew immediately before this.
In fact, it would undo all the previous lines in the order that they were drawn.
The REDO would be the exact opposite.
Any ideas? Thanks in advance
