In java, JFrame is Heavy Weight Component or Light Weight Component?

Question

I Know Swing is considered lightweight because it is fully implemented in Java, without calling the native operating system for drawing the graphical user interface components.<

Answer 1

JFrames are heavyweight, since it's impossible to create a task-view-level window in most OS without creating a "heavy" AWT window. Lightweight components can replace internal widgets with java-based stuff that doesn't require JNI calls, but windows are the special case. JFrame does let you do custom renders, though. Also, if you're using other lightweight stuff, then I suggest using JFrame as well since it makes the rendering more efficient overall than mixing light and heavy components.
