Is there any way drawing lines/curves in flex/fb4 -like pen tool?
Because it is not a practical method drawing with only <s:Line/>'s. Maybe an external tool which lets you draw and get the code for flex/fb4?
I want to draw something in IDE as a part of my application, my application is not going to be a drawing application.
Draw your interface in Illustrator. Run it through catalyst, and make a custom component. Or you can export flash components( swf's so no code ) from Illustrator directly IIRC.
