How do I write superscript word for checkbox text in java?
So I have this very simple program that basically consists of a GUI with a few text fields and a button.
The idea is that the user enters numbers into three fields and presses the button. Then what happens is a few mathematical procedures are carried out in the background, and the resuling answer is presented in a fourth text field.
Now, this does the job, but the formatting looks awful. At the very least, I would like to have part of the output superscripted. I have next to no experience with these things, but thought I would be able to get the hang of this on my own, but I'm stuck. I think I need to use AttributedString and possibly Font, but I can't get anything to work. And I've found no tutorials.
Does anyone have any quick pointers? That'd be most helpful!
Do you need the output field to be editable? If not, try using a JLabel with HTML code. Something like:
jLabel4.setText("<html>ax<sup>2</sup>+bx+c</html>");
You can add a border to that JLabel to make it look like a text field.
Why not use other swing components that support HTML to display the answer like JLabel. If you use a JLabel for instance you can use inline html to format your answer
The reasons you are having difficulty has to do with the lack of a default typsetting system. Font selection and such typically provides a very limited means to do proper math typesetting (which is a specialized subset of general typesetting).
I don't know of any math specific typesetting already built-in to the Java libraries, that said, perhaps you can integrate the ExTex project into your Java components or roll your own solution using the 2d API (look at baseline offsetting).
Other alternatives are to generate a graphic, and display it's rendered image. If the display is static, this might be a much easier choice.

I am creating an application that calculates how fast a person can type by calculating WPM and CPM. However I have hit a snag with the UI as I found out that you cannot really highlight individual strings in a TextArea. My goal is to compare what the user is typing to the random text that is generated by having it so that the text is being dynamically coloured or highlighted as the user is typing.
See http://10fastfingers.com/typing-test/english to get an idea of what I mean
I recently read the following post Highlighting Strings in JavaFX TextArea
I was trying to achieve the same goal of highlighting individual strings inside a javaFX TextArea until I realised that it pretty much is not possible. So I looked into TextFlow which does allow me to edit individual strings. The problem with TextFlow is that all 200 of the generated words would have to appear at once which is not what I want. With a TextArea not all the text has to be displayed at once.
This is what I have so far just so that you can further get an idea of where I am heading with this.
I have been programming in Java for years and I know how to do things far more complex than this, but I can't figure out for the life of me how to do this. Believe it or not, I couldn't find anywhere on the web that could tell me how either.
I'm displaying a string that's stored in a variable and I need to be able to display a less than symbol/ store it in the string variable. So far, the rest of the string prints, just omitting the less than symbol. If it matters, I'm displaying it in a JLabel. Also, I've tried using unicode and that didn't work. Thanks!
JLabel and many other Swing components support rendering HTML, so if the component thinks your text is HTML, you need to escape < as <.
I have been looking through forum posts, blogs, videos, and various other websites for the past hour trying to figure out how to display text on the screen. From what I have seen this is not very simple to do. (Maybe it is once you know how to actually do it)
I decided (with a bit of regret) to post this question here. I am sorry if this question has already been asked a million times, but I am just not understanding how to get this to work. All of the code I have tried so far has not worked.
I would just like to know how I can display text on the screen. I do not want to use my own font or anything fancy. I would just like to know the simplest way to display text on the screen.
The simplest way would be to use Slick. Here's a link to the page specifically about loading and using fonts within your LWJGL program:
Slick-Util (Part 3) - TrueType Fonts for LWJGL
I am learning java currently and I love the newbostin, he makes simple fast tutorials but to display text I'm pretty sure u need to
1: have eclipse
2: make the base of it (the main string, idk how actually)
3. The actual code to do it is println("text here")
I'm not completely sure so you should check out the newBoston he is awesome at explaining.
Doing linguistics and phonetics, I often need to use certain special phonetic symbols. Although I'm using a special keyboard layout that enables me to write some of those characters by typing, they key combinations can often get both quite complex and highly repetitive, so I would like to create a litle app that would contain some buttons, perhaps, each of them capable of sending a specified (phonetic) symbol to whatever the current cursor position is, no matter what window on one's screen is in focus.
Is anything of this sort possible to do in Java?
I've seen a solution that copies the values into clipboard and then pastes them (Java paste to current cursor position), but that is not a very clean way to do it, is it? Is there a way better than just pasting the charactedr(s) via ctrl+V?
Many thanks for any help or advice in advance!
P.
You can use the AWT Robot to generate key press events. This will not provided the ability to insert arbitrary unicode characters but you can combine it with the technique you already described: transfer the unicode characters to the clipboard and generate a CTRL+V key event afterwards. You can try to save and restore the original clipboard content but this will work with types supported by Java only.
The focus problem mentioned in the comments can be solved by setting the window to not receive the focus via Window.setFocusableWindowState with an argument of false.
An alternative is to provide the unicode text via drag&drop. Most applications support dropping text in their input fields. The code for exporting the text is very similar as both, clipboard and d&d use the same interfaces in Java.
Hi i'm looking for a way to highlight specific words in text kind of like how a text editor might work with syntax highlighting. The highlighting will consist of the text being different colours and/or different styles such as italic, bold or regular.
In order to narrow focus, how this might be achieved using Java Swing components.
There are most probably a number of ways of doing this but one that is efficient in dealing with multiple highlighted words and large amounts of text.
Any feedback is appreciated. Thanks.
You can use the Highlighter that is available through JTextComponent's setHighlighter().
Have a look at Java's JEditorPane class: it does what you want.
I would use a JTextPane. Its easier to use than a JEditorPane as you don't have to know or worry about HTML. The link you where given to the Swing tutorial covers both components.
You probably need something like RSyntaxTextArea. I personally like it because:
- it's easy extendable
- it comes with really useful plugins
- opensource & free & maintained
- it supports bunch of languages like: C, Java, Ruby, Php, HTML, CSS, Sql and so on.
