I'm using "Flow Text View" to wrap my text around a picture.
But them problem is, I'm using Persian language so I have to set text direction to "RTL" but have no idea how to do it for the Flow Text View.
Here is a picture of how my texts get while direction is LTR...
I hope to help me how to set direction to rtl, I will provide any code you need and I will answer immediately.

I looked on google but didn't find what exactly i am looking for.
I want a edit text to have text or image which i can change by tapping it and selecting new text or image. Also i want hint followed by that text or image.
I tried multiple experiment and was able to add text(by changing selection location and adding text) and image(using drawable addition from android code)
For text :
edt.setText("Fixed Text");
Selection.setSelection(edt.getText(), edt.getText().length());
Image through XML:
android:drawableLeft="#drawable/ic_launcher"
But when i add text, i won't be able to add hint. In case of image hints get added. Also i want my permanent text and image to be tappable and updatable.
Any help would be really helpful. I want $ to be fixed and tappable, and want to change it to different currency. but want 52.63 to be hint and can be editable by user tap.
EDIT to give more clarity:
Example: i want to add part of the text as permanent and part as hint for example $ 52, so $ is permanent and not editable through user, he can select it through list view by tapping on $, but 52 he can change using android keyboard.
I am not quite sure about the whole part about the image being placed into the EditText as a hint, but if you wanted to create the $52.63 as a hint in the EditText, all you would have to do is:
edt.setHint("$52.63");
in your onCreate() method. I am not sure if this is what you are looking for, but this is a simple way to add a hint to a textEdit. If you wanted the hint to change when the user tapped the screen or something like that, I would look into adding a tap listener of the android component that you desire to be tapped to change the hint, and then modify the hint using the method above.
Right now, I'm using Java Swing to create a JEditorPane primarily for its ability to have hyperlinks. I've successfully been able to display links and have them execute behavior upon a click, but I'm running into a few problems with formatting.
How can I set the cursor so that it normally is an arrow, but changes to a text cursor when hovering over text? (In essence, the behavior a cursor has within a web browser). I tried
EditorPane.setCursor(new Cursor(Cursor.TEXT_CURSOR))
but that made it a text cursor everywhere, even when not hovering over text. Right now, hovering over a link shows a pointer hand; I'd like to maintain that functionality as well.
What is the best way to show tooltips or mouseover text when hovering over a link? I tried modifying the title attribute of the link but nothing showed up.
I was trying to implement links to skip down to a subsection of the page, much like http://en.wikipedia.org/wiki/Xkcd#History would take you directly to the History subsection of Wikipedia's xkcd page. How can I do this?
An answer to any of these would be great (and multiple would be awesome xP). Thanks a lot for your help!
As you said one can simply give answers to a single point as well, let me try one by one, here is the answer for your last Point 3
Just provide an id to your tag like this
<h1><a id = "top"></a>First Line</h1>
Now somewhere in the bottom of your page write this :
<p>Return to TOP</p>
Clicking this link, you will reach the above area of the PAGE.
Points 1 & 2 may be addressed using the approach mentioned here. In particular, the view/model conversion methods will let you condition setCursor() and getToolTipText(), respectively.
You can get source from here http://java-sl.com/JEditorPaneStructureTool.html
It shows how to obtain text view bounds. First you get caret position for current mouse poiunter using viewToModel() method. Then go down the Views tree achieving leaf view and calcualte it's bounds. See this http://java-sl.com/tip_view_rectangle.html
If your mouse pointer in the view's rectangle then your mouse over text.
You can check whether the text in caret position is link and show your tooltip.
Use this http://java-sl.com/tip_links_in_editable.html to see how to detect whether mouse is over link.

I want to change color of text written in JTextArea. For e.g. I am pasting Java code in JTextArea.
I want to give the different-2 color to Java keywords, variables and classes written in code.
Is it possible?
See Rob Camick's Message Console. It seems perfect for this use case.
Actually '2 color' might not be enough for this.
See How to Use Editor Panes and Text Panes for more details on the formatted text components that might replace JTextArea.
it's not possible
if you want to set different colors in the same area, i think JTextPane could help you
i'm not sure how to use that, but i found this

I'm just figuring out my way around SWT. I have a little problem that i cant seem to solve. I have a check-box in my window. When the check-box is checked, i would like add a multi-line, read-only, text box below it, lets say 200x200. I want the height of the window to increase to accommodate this text-box. When the check-box is unchecked I'd like the opposite to happen.
Could you help me with this? I can't find an example but maybe I'm not using the right keywords. Cheers.
--EDIT
the.duckman'ss answer was very helpful. I've managed to get it working to some extent. I'm adding a multi-line textbox 480px high. How do I automatically resize the window to accommodate the text box? When the user checks the checkbox, the textbox shows up but the height of the window doesn't increase to accommodate the textbox. My code is a little long so I've put it in PasteBin — http://pastebin.com/01RxKeEr
Thanks.
I recommend looking at the SWT Snippets to every beginner - that's probably the best place to go to with SWT questions.
This snippet does exactly what you want.
Edit
Ooops, I ignored the second half of your question, sorry. Simply add this line to your listener:
shell.setSize(shell.computeSize(SWT.DEFAULT, SWT.DEFAULT));
I'm trying to make it so when I tab to some text fields on in my JFrame the data in the text field will be highlighted. I thought I had done this in the properties before but I am not seeing the option now. Does anyone know how to do this?
You could use a FocusListener to work out when your field has focus (tutorial here).
Decide whether you want to select the text in the field, or whether you just want to change the background color. It's not quite clear what you mean by highlight.
