19:02	* mr_lou	struggles with old Java.
19:02	mr_lou	Toolkit.createImage is putting up an attitude.
19:04	aditsu	try some new java instead? :p
19:04	* aditsu	is trying to use a quickbooks sdk
19:05	mr_lou	aditsu, No I insist on getting this running in old Java.
19:06	mr_lou	And it should run.
19:07	mr_lou	java.awt.Image myImage = java.awt.Toolkit.getDefaultToolkit().getImage("/myImage.jpg");
19:07	mr_lou	or
19:07	mr_lou	java.awt.Image myImage = java.awt.Toolkit.getDefaultToolkit().createImage("/myImage.jpg");
19:07	mr_lou	But myImage.getWidth(null) is -1. I.e. nothing is loaded. Have tried with different filetypes too. Running out of things to try.
19:08	aditsu	is your image in the root directory?
19:10	mr_lou	Yes
19:10	mr_lou	Root of jar
19:11	aditsu	I think "/" means root of file system
19:13	mr_lou	Well I've tried with and without /
19:13	mr_lou	(For MIDP and BD-J I need to use / to go to root of jar).
19:13	aditsu	is it a separate file? or only inside the jar?
19:13	mr_lou	Inside jar
19:13	mr_lou	png and gif and jpg
19:13	aditsu	then I don't think you can use createImage(String) at all
19:14	aditsu	try the URL version
19:14	mr_lou	hmkay
19:15	aditsu	and you can use getResource from Class or ClassLoader
19:15	aditsu	to get a URL for something in the classpath (which includes your jar)
19:16	mr_lou	Tried those too. :-)
19:16	mr_lou	getClass().getResourse()
19:16	mr_lou	getClass().getClassLoader().getResource()
19:17	mr_lou	Nothing
19:17	aditsu	let me give it a try then..
19:18	mr_lou	Nothing
19:18	mr_lou	ups
19:19	aditsu	?
19:19	mr_lou	Hit arrow up and return in here instead of in consol.
19:19	mr_lou	I use this method in BD-J, and it works fine there.
19:20	mr_lou	But apperently not now here in old desktop java.
19:21	mr_lou	Ah...
19:21	mr_lou	Got something now.
19:23	mr_lou	Managed to get a simple test working.
19:24	mr_lou	So the only difference at this point, is the MediaTracker I attach to it...
19:24	mr_lou	Hm
19:24	aditsu	yeah, I think it may not load instantly
19:27	aditsu	you can also use the ImageObserver thing if you prefer an async approach
19:28	mr_lou	I do prefer async, but I can't figure out this ImageObserver thingy.
19:28	mr_lou	I think the javadoc I found is too simple.
19:28	mr_lou	http://www.ad.ntust.edu.tw/course/ad5601701/jmdl/docs/java/api/packages.html
19:29	mr_lou	But anyway.... it's still not the issue.
19:29	mr_lou	It's not loading ever in my other app.
19:30	aditsu	you can also check https://docs.oracle.com/javase/8/docs/api/java/awt/image/ImageObserver.html
19:30	mr_lou	I use the MediaTracker to force my app to wait untill the image is loaded.
19:30	mr_lou	Works for BD-J
19:31	mr_lou	I can't use the ImageObserver to halt my application. I'll have to implement some manual waiting time then.
19:31	mr_lou	MIDP was nicer this way. :-)
19:31	mr_lou	It would halt everything while loading images.
19:32	aditsu	sounds like you don't want async; just use MediaTracker then
19:33	aditsu	mr_lou: I also want to ask.. can't you use ImageIO?
19:33	mr_lou	No. ImageIO wasn't invented till much later - at least that's been my impression for a long time.
19:34	mr_lou	hm... since 1.4 apparently.
19:34	mr_lou	That's pretty old.
19:39	mr_lou	while (image.getWidth(null)<=0) Thread.sleep(100);
19:39	mr_lou	That works.
19:39	mr_lou	Until I call image.getWidth(null) later on again. Then it's NullPointer
19:41	mr_lou	Oh wait, that was my bad.
19:41	mr_lou	:-)
19:43	mr_lou	I'm a dumbass.
19:43	mr_lou	Next time, just remind me of that.
19:43	* aditsu	makes a mental note then quickly forgets it
19:45	mr_lou	You're right about / though. I need to omit it here. But I need to include it for MIDP and BD-J.
20:09	aditsu	sigh.. I hate bloated dependencies
20:13	aditsu	this is what my classpath looks like: http://farm2.static.flickr.com/1223/1356857214_705c36eaa6.jpg
20:25	mr_lou	:-)
20:28	mr_lou	If I don't answer, I've fallen asleep.
20:28	aditsu	good night
20:49	pdurbin	don't let the bed bugs bite
21:57	mr_lou	Damn mosquito woke me up
21:57	mr_lou	That's why I often sleep with ear-plugs.
