Hei! I have an homepage www.eurojari.net containing an applet runnable.. if i add an image to my applet witch has an question of yes or no 'shall we open a window' then, how to i: open fullscreen sized window ready to receive Graphics2D commands from my applet run().. thank you for helping a relative new person on java, c is more familiar to me but net and java is quite a new.. very much thank you..

After visiting your homepage, and waiting several minutes for the multitude of images and resources to load, I saw a message about how this site was best viewed at some 'screen resolution', and left. I realise you were not asking us to critique the homepage, but I will. Remove most of the images, or include tiny versions (in both WxH and bytes) on the homepage, but link to large versions. Move the applet from the homepage, onto a page where the user is warned to expect to 'wait a few moment' for it to load, or better, load it using webstart in a free floating window. Designing for a particular screen size fell out of fashion last millenium, make web sites for the users' screen size instead. The bottom line of the web page (re., updates) has a typo.

Is this an Applet or JApplet? Andrew T. Back to top Andrew Thompson Guest Posted: Wed Oct 11, 2006 7:11 am    Post subject: Re: Java Windows question.. JTapio wrote: ..... Quote: this is how far i have get.. please help to add canvas to frame.. Why do you want to create the canvas in the applet, rather than simply make it in the frame? (Note that if overriding 'paint' I will usually choose a Container, since there is often no need for anything more.) Quote: public void init() { Canvas canvas = new myComponent (); canvas.addComponentListener( new ComponentListener ()); // this line needs help.. What is the purpose of listening to the canvas? (I have done similar things, but until I understand exactly what you are trying to do, what it looks like in the applet, and what actions cause the frame/window to appear - I cannot help much) As an aside, the difference between a frame and a window is that a window has no decorations - no 'title bar', no 'close box'.. The code example I posted earlier in the thread, showed a full-screen window popping from an applet (which is quite bad if it has no button to close it & the way I did it, meant the user could not get back to the web page with the applet!).

You can feel safe and fine,with applet.. I need a code peek of putting an canvas to an frame..

There is really no difference in security. Compare the sandboxed/all-permissions end-user difference. Sandboxed <http://www.physci.org/pc/jtest.jnlp> all-permissions <http://www.physci.org/giffer/giffer.jnlp> (both those were written and 'published' by me, though the second hooks into an open source GIF animation library.) * I use IE, and have not bothered to remove the 3810 MSVM. If my settings get messed up and I cruise into a malicious page with the MSVM as the default VM, the web master has the potential to find the root location of the (MS) VM installation on my PC, using a *sandboxed* applet. That would not be possible with a sandboxed web start application or applet (or any other VM). Andrew T.
