java - Unpredictable behaviour with Processing -

i've started creating application in processing, , i'm getting unpredictable behaviour when place papplet object jframe using borderlayout.center.

the width of papplet 100 less width , height of jframe. on occasions, when click 'run', programme fills screen , runs smoothly, on other runs, papplet starts top left , leaves gap on 100 on bottom of screen , left hand side, , quite laggy.

i have no thought going on if i'm honest.

this result runs smoothly:

this unpredictable one:

here code i'm using:

papplet subclass public class jcanvas extends papplet { /** * papplet method - performs setup actions */ public void setup(){ size(1400,900,p3d); background(80); } /** * papplet method - drawing occurs here */ public void draw(){ background(80); pushmatrix(); translate(mousex,mousey, -199); fill(220,0,0); box(120,500,90); popmatrix(); } } viewer class public final class euroviewer { private final static int width = 1500; private final static int height = 1000; private final static boolean resizable = false; public static void main(string[] arguments){ final jframe frame = new jframe("eurographics papplet"); jcanvas sketchcanvas = new jcanvas(); frame.add( sketchcanvas ); frame.setdefaultcloseoperation(jframe.exit_on_close); frame.setsize(width, height); frame.setresizable(resizable); frame.setlocationrelativeto(null); sketchcanvas.init(); frame.setvisible(true); }

}

i tried replace jframe awt.frame incase there stability issues between swing , awt (which i'm led believe papplet built off of) in paticular case.

surprisingly plenty though, there never lag frame, has kind of solved issue. but, i've used jframe, gui work containers etc i've done swing, wondering if share knowledge , explain going on, , if possible fix? issue.

thanks.

it’s not recommended combine processing sketches swing. unpredictable behavior has been reported lot of times.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
