Hello,

i use GLGraphics in a sketch to be able to have a full version of the applet and a preview version of the window so that i can see what i'm doing while projecting on an external display. i implemented the code on OSX and it run fine there, but on Windows 7, as soon as i call
      new  GLTextureWindow(PApplet parent, int x, int y, int w, int h) ;

Then a windows pop arise tell me the program has crashed and windows is looking for a solution...

Has anyone used GTTexureWindow sucessfully on windows ?

thanks for your help !

Hi all,

i am trying to have a second window (to display a preview of the main windows using FBO like explained here : http://processing.org/discourse/yabb2/YaBB.pl?num=1207160412/15 )

but the code is crashing : java JVM crashes with no message (i am on windows 7 32bits java 1.6_021 with nvidia video card)

the crash seems to be related to attaching the GLCanvas to the JFrame and displaying it. (displaying the windows without attaching the canvas to it, or not displaying the window seems not to crash).

any idea ?

Hello,

i run a processing application and with controlp5 control window and a main output frame. i would like to have a preview of the ouput frame within the controlP5 control window.
As i use openGL ouput, i was wondering if it would be possible to render a resized preview of my main ouput window within my control window using some accelerated openGL cloning thing (just like windows 7 can display a preview of the window above the task bar when i hover my mouse above the application like the last thumbnail on the right on this picture : http://img87.imageshack.us/img87/3162/vipohtm.png). so this must be possible by grabing the frame content, and making it a texture and drawing it resized on the control window. i just don't know where to start looking.

i remeber compiz linux window manager had to have a card supporting GLX_EXT_texture_from_pixmap in order to be able to enable desktop composition... that might a be a lead.

any idea on how do this ? i searched the forum but did not find much information.

thanks in adavance.
