This looks as easy as in .NET:

Code: [Select]

textBox1.Undo();
textBox3.Redo();
While trying to implement a Font Dialog, I came across an automatic Font Dialog, but it needs to import stuff like:

Code: [Select]

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.graphics.Color;
import org.eclipse.swt.graphics.Font;
import org.eclipse.swt.graphics.FontData;
import org.eclipse.swt.graphics.Image;
import org.eclipse.swt.graphics.RGB;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.FontDialog;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;

Both NetBeans and Eclipse say that those imports are invalid. Is it a special download?

why do you need all those classes? and yes they seem like a package you would download from the internet for extended usability of Eclipse.

I really need to add Undo/Redo so that this has some value, but I can't do it, anybody knows how to?

I know how to, but for a text editor, it's a little more complicated.  Essentially, you need to store a certain number of "actions" into a buffer (Say 30), and then be able to undo and redo them. I would have two stacks. One is for Undo, and one is for Redo. Actions go on to the Undo stack.  When you "undo" them, they swap to the redo stack, along with being undone. When you redo, if there are any on the "redo" stack, you swap them to the undo stack, and redo them.

As for how much text you decide is an "action", or how you deal with that, is up to you. As long as you can undo and redo it.

this is exactly what i do for my tilemap editor. i can give the method for manipulating the stacks if you want, scout. though it may be better to learn about the package javax.swing.undo, because it was built for redo/undo in things like a text editor. my tilemap editor is really simple because you can only undo or redo placing a tile. in a text editor it's probably more complex.

Oh, I'd forgotten about that. One of the optimizations in the documentation is to not add a Return to the end of the program

that's an auto-optimization already.

fixed .jar file uploaded in the same place. i'm off to go to a movie, if there are any more bugs leave them here and i'll deal with them once i'm back.

That's actually some pretty good code, nemo. I like the way you handle error messages, too.

i always used to get mad when i entered 5 pieces of information, and the software took the time to point out each error message individually, rather than just give me everything i'm doing wrong. thanks graphmastur

Wow, a lot happened in 2.5 hours...

Deep thought, thanks for the changes!  Nemo, you too!

I would like it, though, if all text boxes are blank at the beginning.  Also, I have a screenshot of a file I tried to compile and an error box with no error message.  Finally, your error message for ending/starting characters should be "larger than or equal to" as opposed to simply "larger than."

And just like Deep Thought, don't push yourself to go "above and beyond the call of duty."  Plain 'ol monochrome, uncompressed bitmaps are fine

yep, i already reattached a fixed version, hoping no one would notice, but you did. new version attached in the same place.

Deep Thought, forget the GUI, i've got it covered.

Great, some info if you need it:

My program doesn't prompt for the name of the font. It just takes the name of the bitmap, strips the ".bmp," runs toUpperCase(), and pads it with zeros until it's eight characters long. So basically, whatever the bitmap's called is what the .8xp is called. Not sure what Hot_Dog wants, though.

Any questions about the code, just ask me

i noticed that. the GUI has a name field though, so i plan on doing the same operation as you except take it from the name field.

i gotta say, your code is interesting to go through. how did you figure out that 16973 is the identification of BMP files?

anyway, hot dog, as you may or may not know i'm pretty good at dealing with images in java (*cough* juggernaut *cough*). i know a way i could extend the allowed filetypes to other lossless compressions, like PNG and GIF, granted that they are monochrome.
edit: nevermind, i could not. i wouldn't want to tamper with Deep Thought's code, now that i think about it.

edit2: done! hot dog, let me know if this works. jar file attached.

Nice. The only suggestion I would have though is to make the text larger, or maybe add an option menu to increase the size.

What text format does it support? Does it also support unicode?

It supporst most ASCII symbols like the STO arrow UNICODE I don't really know what that is :S

I am including a colour/text format option in a near future

Ah ok I was more wondering about formats like RTF, DOC, etc. But I was also curious about ASCII/UNICODE. Would it open Illusiat 81 readme fine, for example?

i think it would only support .txt files. it's like notepad, you can open whatever file you want but it won't always be human-readable. you could open a GIF but it wouldn't display an image, for example. it would give you the unicode representation of the gif data.
