AttributedString?

**braskez** · 10-08-2012, 07:21 PM

Java Code:

	
String[] cmds = {"exit", "keystrokes", "screenshots", "auditinfo [caller name]", "callerprofile [caller name]", "about", "commandbook", "editcaller [caller name]", "newcaller", "options", "devOptions"};

String[] cmdExp = {" Closes the program", "prints all the keystrokes for that specific caller.", "prints screenshots taken of that specific caller's screen.", "prints the number of audits that specific caller has booked.", "prints general information about the caller.", "opens the about window.", "opens the commandbook.", "opens a window that allows you to edit the caller's info.", "creates a new caller and lets you add info about he/she.", "Opens the options menu.", "Opens the developer menu."};

		for(int i = 0;i<=10;i++){
	    	cmdattribute[i] = new AttributedString(cmds[i]);
	    	cmdEXPattribute[i] = new AttributedString(cmdExp[i]);
	        }

I have no idea what I am doing wrong here. Also I declared cmdattribute and cmdEXPattribute earlier.

Java Code:

public AttributedString[] cmdattribute = null;
public AttributedString[] cmdEXPattribute = null;

Here is the error I get:

Any advice is appreciated, thanks

You have to create an array object / allocate memory for 11 AttributeString objects!

I tried doing the following:

Java Code:

public AttributedString[] cmdattribute = AttributedString[11];
public AttributedString[] cmdEXPattribute = AttributedString[11];

But it just told me that AttributedString couldn't be resolved to a variable.

**eRaaaa** · 10-08-2012, 08:12 PM

did you read the link? It appears not!

new AttributedString[11] !

Thanks, I'm closer to where I need to be, but I am trying to drawString the attributed string, but I am not sure how to specify which JFrame I want it to draw to. The one I want it to draw to is named 'commandBookWindow'.
I tried

Java Code:

			commandBookWindow.add(g.drawString(cmdattribute[0].getIterator(), 30, 30));
			commandBookWindow.add(g.drawString(cmdEXPattribute[0].getIterator(),30,30));

but that didn't work at all. Any ideas?

Anyone?

I would recommend that you "draw" your String in a JLabel via its setText(...) method rather than drawing with a Graphics object. If you're required to use the latter due to homework requirements, then you'd draw in a JPanel's paintComponent method and would use the Graphics object passed into the method's parameter from the JVM. The Swing Performing Custom Painting Tutorial will tell you more about how to draw with Swing.

I tried the JLabel but instead of printing the string value I assigned earlier it printed something weird.

Java Code:

commandBookWindow = new JFrame();
JPanel topPanel = new JPanel();
topPanel.setLayout( new BorderLayout() );
commandBookWindow.getContentPane().add( topPanel );
commandBookWindow.setSize(300,300);
JLabel commandBookText = new JLabel(); 
String[] cmds = {"exit", "keystrokes", "screenshots", "auditinfo [caller name]", "callerprofile [caller name]", "about", "commandbook",
	"editcaller [caller name]", "newcaller", "options", "devOptions"};
String[] cmdExp = {" Closes the program", "prints all the keystrokes for that specific caller.", "prints screenshots taken of that specific caller's screen.",
	"prints the number of audits that specific caller has booked.", "prints general information about the caller.",
	"opens the about window.", "opens the commandbook.", "opens a window that allows you to edit the caller's info.",
	"creates a new caller and lets you add info about he/she.", "Opens the options menu.", "Opens the developer menu."};
for(int i = 0;i<=10;i++){
	    	cmdattribute[i] = new AttributedString(cmds[i].toString());
	    	cmdEXPattribute[i] = new AttributedString(cmdExp[i].toString());
	    }
String fontType=this.getFont().getFontName();
int fontSize=this.getFont().getSize();
Font bold = new Font(fontType,Font.BOLD,fontSize);
Font italics = new Font(fontType,Font.ITALIC,fontSize);
for(int i = 0;i<=10;i++){
	cmdattribute[i].addAttribute(TextAttribute.FONT, bold);
	cmdEXPattribute[i].addAttribute(TextAttribute.FONT, italics);
}
commandBookText.setText(
	cmdattribute[0]+" - "+cmdEXPattribute[0]+"\n\n"+
	cmdattribute[1]+" - "+cmdEXPattribute[1]+"\n\n"+
	cmdattribute[2]+" - "+cmdEXPattribute[2]+"\n\n"+
	cmdattribute[3]+" - "+cmdEXPattribute[3]+"\n\n"+
	cmdattribute[4]+" - "+cmdEXPattribute[4]+"\n\n"+
	cmdattribute[5]+" - "+cmdEXPattribute[5]+"\n\n"+
	cmdattribute[6]+" - "+cmdEXPattribute[6]+"\n\n"+
	cmdattribute[7]+" - "+cmdEXPattribute[7]+"\n\n"+
	cmdattribute[8]+" - "+cmdEXPattribute[8]+"\n\n"+
	cmdattribute[9]+" - "+cmdEXPattribute[9]+"\n\n"+
	cmdattribute[10]+" - "+cmdEXPattribute[10]
);
cbwScrollBar = new JScrollPane();
cbwScrollBar.setVisible(true);
commandBookWindow.add(cbwScrollBar);
cbwScrollBar.getViewport().add(commandBookText);
commandBookText.setVisible(true);

I apologize for it being length. Anyways here is the string it wrote back to me:

java.text.AttributedString@6ff3cb0e - java.text.AttributedString@4d6c3541
java.text.AttributedString@3863aace - java.text.AttributedString@1762d74e
java.text.AttributedString@5a254de0 - java.text.AttributedString@59ebd60d
java.text.AttributedString@1e71b324 - java.text.AttributedString@26e7ee9f
java.text.AttributedString@f7fb9e0 - java.text.AttributedString@a842913
java.text.AttributedString@6aa4a3c9 - java.text.AttributedString@5efd17d1
java.text.AttributedString@3bb508b6 - java.text.AttributedString@6a4f0359
java.text.AttributedString@6964fe95 - java.text.AttributedString@65861e41
java.text.AttributedString@482c7179 - java.text.AttributedString@5dcde3f3
java.text.AttributedString@783096a1 - java.text.AttributedString@3df161ac
java.text.AttributedString@324382f9 - java.text.AttributedString@6e4bc336

Except don't include the line breaks above. It printed it all on 1 line.

There's nothing strange about this result as you're seeing the default String returned by the AttributedString class's toString() method. It defaults to the method used by Object which shows the class name, @, and the hashCode for the object. Why instead of printing out the object's toString(), why not get its text. So if the class has a getText() method, then call it. Also use a for loop here to reduce your code by > 50%

**braskez** · 10-09-2012, 03:48 AM

From what I see, unless I am doing something incorrectly, the class doesn't have a getText() method. Any other alternatives?

Surely the class has an equivalent. What method do you have that returns the String that was passed into the constructor?

**braskez** · 10-09-2012, 04:31 AM

Would getConstructor(String.class); work? I'm still pretty new to this whole thing.

No, that's only for building the object. Surely the class has a method for extracting that String that passing into your constructor, right? If not, please give it a "getter" method for this purpose and use it in your code above.

So, how would I do that?

**Fubarable** · 10-09-2012, 11:34 PM

First please show us your AttributedString class code.

Well, I'm not exactly sure what you mean. I just started learning java a couple days ago so I don't know all the lingo. I do have a lot of experience with javascript, html, css, php, all that stuff so I do have some general knowledge of programming. So I suppose I will just give you my entire script. Just warning you it isn't very well organized and I probably did things the long and tedious way. But I'll get better I just got to get the hang of it. Anyways here is the code:
