Layering PApplets (Read 598 times)

samthakur74 YaBB Newbies Offline Posts: 16	Layering PApplets Dec 14^th, 2005, 2:02pm Hello, Is there any resource which shows examples using layering in processing? Specifically i would like to layer PApplets. Can this be done? What are implications of Z order on receiving user inputs? Is it that only the top layer can receive inputs? thank you Sameer

Are you talking about layering at the web-page level, or layering at the processing level?

At the web-page level, it'd work just as you expect, applets wouldn't be transparent and only the topmost one would receive input. However, it's quite likely for browsers to give you grief when you try to layer them.

At the processing level, it's simply a matter of designing your code to that effect. I could go into detail, but the approach really varies depending on what you're trying to do.

Thank you for the response.
The layering i need is not for the web pages.
I have a java fat client which is displaying super contig/contig and base pair data. I was exploring the possibility of using layers to superimpose information instead of having multiple views and trying to synchronize information between them. I am using a Papplet to show the supercontig/contig and base pair information. The PApplet is inside a swing container. I plan to layer only the Papplet area.

thank you

This would be a little complicated because PApplet is a heavyweight object, and Swing doesn't always play well with heavyweight layering (for example if you used JInternalFrames, the PApplets of windows beneath the active window would display above the active window's border).

You would want to do a little hacking to get PApplet (or even use PGraphics directly) to function as a lightweight Component, then you could use it as a normal Swing widget in your GUI.
