Fonts (Changing Fonts and Color's)

[dbashby]

I am trying to make it so that the following code changes fonts and color

if (outputBmi < 18.5) {
                            txtResults.setText("Underweight");
                            //Needs to be orange
                            txtResults.setFont(new Font("Serif", BOLD, 18));
                                } else{
                                    if (outputBmi > 24.9){
                                       txtResults.setText("Overweight");
                                       //Needs to be red
                                        } else
                                            txtResults.setText("OK");
                                            //needs to be green

The line

txtResults.setFont(new Font("Serif", BOLD, 18));

gives me an error, it doesnt like BOLD, I thought that the import java.awt.*; contained the library for fonts so surely BOLD should not casue this problem?

I am also looking to change the colour as per comments under each statement.

Thanks in advance for any assistance

After searching the web and going through books I have tried several things, the latest is

Font font3 = new Font("Papyrus",Color.ORANGE, Font.BOLD,20);

this doesnt like Font, yet when I have

Font font2 = new Font("Ariel", Font.BOLD, 17);

it accepts this

can someone advise as to whether I am making this more difficult than it needs to be?


Thanks

Have you reviewed the Font API? That's where I'd start. Reviewing this shows no constructor that accepts a Color parameter.

What is "txtResults", a JLabel? If so, then perhaps you want to set its foreground color via setForeground(Color.YELLOW)?

[dbashby]

txtResults is the text field that displays 'ok', 'underweight' or 'overweight'

I am currently looking at the link you suggested , ermm ok, i admit it, im lost, I dont see anything to tell me what I want to do.

looool b4 any1 posted a reply to this thread i was answering your question, but my laptop ran out of battery and it closed :P .. Anyway ,,

to change the font you need Font.BOLD instead of just BOLD but i see you figuered that out .

To change the color of the text :

txtResults.setForeground(Color.RED);  // or any other color

or u can

Color c = new Color(int,int,int); // and define the values

Thats great, thanks for your help, glad your battery didnt take to long to recharge...lol

They are working apart from the overweight, this is printing out in green rather than red.

if (outputBmi < 18.5) {                                                        
                            txtResults.setText("Underweight"); 
                            txtResults.setForeground(Color.ORANGE);
                            txtResults.setBackground(Color.BLACK);
                                } else{
                                    if (outputBmi > 24.9){
                                       txtResults.setText("Overweight");
                                       txtResults.setForeground(Color.RED);
                                       txtResults.setBackground(Color.BLACK);
                                        } else
                                            txtResults.setText("OK");
                                            txtResults.setForeground(Color.GREEN);
                                            txtResults.setBackground(Color.BLACK);
                                            //needs to be green
                      }

Green !!!? huh .. i have never encountered anything like that :P .. BUT try putting curly brackets in the last else statement . coz usually when u dont put brackets after an if or an else statement in java, java only reads the next line .. so ...

else
Statement1 // only statement1 executes
Statement2

else{           // here both statement1 & 2 are executed
Statement1
Statement2 
}

I hope u understood what I meant :)

lol just to be clear ill show u in ur example

if (outputBmi < 18.5) {                                                        
                            txtResults.setText("Underweight"); 
                            txtResults.setForeground(Color.ORANGE);
                            txtResults.setBackground(Color.BLACK);
                                } else{
                                    if (outputBmi > 24.9){
                                       txtResults.setText("Overweight");
                                       txtResults.setForeground(Color.RED);
                                       txtResults.setBackground(Color.BLACK);
                                        } else [COLOR="Lime"]{[/COLOR]
                                            txtResults.setText("OK");
                                            txtResults.setForeground(Color.GREEN);
                                            txtResults.setBackground(Color.BLACK);
                                            //needs to be green
[COLOR="lime"]}[/COLOR]
                      }

lol, thanks for that, those braces get me every time

I am currently looking at the link you suggested , ermm ok, i admit it, im lost, I dont see anything to tell me what I want to do.

With practice, you will find the API to be your best friend, and if you are going to be coding in Java, you need this friendship. I strongly suggest that you start studying the API daily so that you will learn how to use it. If you do this, you will get better at using it, and you will be able to answer your own questions much quicker and more easily than you can get answers here.

Best of luck.

So having the colors displaying as required, I have a further question

I have a optionPane that if the user clicks Help will get the instruction of the use of the app

Within those instructions from the information that has already been given here can someone tell me if it is possible to format the text within this optionPane?

I am looking to center & color headings etc

I would think it is but before I try I just want to know if it is possible.

I am still trying to digest the link you gave me fubarable, thanks but at the moment its over my head, I will keep reading it though

Thanks
