I have created a GUI in JApplet Form in netbeans which also contains a JList. i just want to know how to add a text and an image before text. i know how to add a text by creating an array and pass it to the constructor of the JList but that was in simple JPanel but in JApplet Form code is disabled (non-editable).I am stuck into it.In Short i want to add my own items in JList in JApplet Form in netbeans. is there any good tutorial or some help. Need an Urgent Help. Thanks.

I built a form with Netbeans JFrame Form, I mean from netbeanse itself by right click on the project and then New and then JFrame Form. Also I use a Jtable by dragging that on the form. Now in my code I want to colorize the rows on Jtable. I have seen some idea from https://coderanch.com/t/476777/java/Color-Row-JTable But all the direction which I have seen is about overriding Jatble. My problem is In my program netbeans it self does the code in declaration JFrame element from where I can override the code or specifically in this case how can I make the rows colorized ?
If you have already put the JTable in the JFrame you can right click on it and then chose Customize Code.
It will present you a window where some code is written. You can add custom code on the white lines, not the gray ones unless you want to change an already defined property.
Remember though that you should implement your custom cell renderer first.
In case you want to change an already defined property of the JTable, you have to first change the Default Code drop down menu on the left of the property to custom creation.
I hope this will help you out.
I have been researching this topic a lot and haven't found anything that tells me I can add a BufferedImagento a JTextArea or JTextField. I am making a chat application and trying to add smiley faces for the chat. What I am trying to do is put the image right next to the string like it is text. I was thinking if you could put the Buffered image in the format of a char that would help. Please help me! Thank you!
I'd also give a try to JEditorPane.
For motivation see: http://www.apl.jhu.edu/~hall/java/Swing-Tutorial/Swing-Tutorial-JEditorPane.html.
I've noticed that most of the chat applications, show you what you and others wrote in one window (could be JEditorPane with all the smilies displayed as pics) and bellow you can have editable JTextArea showing just text.
The problem is that JTextArea and JTextField, are really only meant to show text, in order to implement something that mixes thetext with images, you would need to extend JTextArea and modify the paintComponentMethod to do custom rendering.
I'm writing a simple text editor in java, I have done it before now I have some new ideas, normally when I put in a JTextArea when I have a FlowLayout on my JFrame it will fill what is left of the JFrame. However this time it's not. Could someone help me out trying to get it to fill the rest of my JFrame? Thanks!

Java does have various layouts. For making dynamic body changes you have to learn more flexible layouts like grid or grid bag layout. Hope this help.
How can I display multiple lines within a single cell of a JList. In jtable, it is achieved by adding a JTextarea to the table cell renderer. Similiarly, Is there any code to add a custom cell renderer for a JList that holds a textarea? If yes, can you please give me a code snippet for the same?
Or do you think there is any other better method to display multiple lines within the cell of Jlist instead of using a textarea? please help me!!
Beside usage of HTML code in Swing component (like Jigar says), you can also specify a ListCellRenderer that uses a TextArea, exactly like you do in your JTable.
Try with html.
"line one <br/> linetwo"
How do I "combine" JButton with JComboBox and place it on a JToolbar, as shown in this image:
?
You'll want to use a custom renderer I suspect, and have it display clickable buttons (with the appropriate actions attached, etc).
Just create regular combo box and put image as an item. I did it once. Unfortunately I do not have a source code here but as far as I remember it was not a problem. You have to implement your custom 1ListCellRenderer. Its methodgetListCellRendererComponent()` should return for example Label with your image.
