In my application I call an API to get the contents of the file as a String and use the TextArea UIWidget to display the file content to the user.
I want the user to be able to select the text in the text area in order to be able to copy and paste the contents of the file. When I hover over the TextArea in GWT, text selection is not being enabled. The getCursorPos function in the TextArea seems to be useful when modifying the textarea but not for selections
Text selection is enabled in TextArea by default. You either disabled it somewhere setEnabled(false), or you put another widget (panel) on top of your TextArea which prevents users from typing in or selecting a text.

I have textarea which show file data content. I have table view which contains line numbers and when double click on table view I can able to retrieve line number so I need to change the color of particular line number in textarea using JavaFx controller. How to do that? Please share your code. Thanks.
Please provide some code.
With the TextArea UI-Control you can only add color to the whole containing text.
For your purpose you should use HTMLEditor to style your text content individually.

I am developing a spam detector application using Java GUI (NetBeans). Now I have a simple user interface which includes a text area in which the user is going to paste his email in to order to check if its a spam or not, but the problem is when you paste a text in the text area all the text properties will be lost such as : Font type, color, hyperlinks etc...
So what should I do?
That's because you need RTF-enabled Swing component to visualize various text properties.
JTextArea is visualizing only plain text. Use JEditorPane or JTextPane instead.
I used JTextPane to read logs which comes from telnet server. Problem is that when the new logs occurred and written to JTextPane, my selected text deselected I suppose that I should change default caret of JTextPane but I could not. Please give an any suggestion I want to preserve my selected text.
DefaultCaret caret=(DefaultCaret)theJTextPaneInstance.getCaret();
caret.setUpdatePolicy(DefaultCaret.NEVER_UPDATE);
You can switch off the update policy.
Without resorting to wrapping a GWT TextArea in a separate DIV, how to add a search icon/magnifier icon inside the text area?
No, Not possible.Text area is not a normal Widget.
GWT's TextArea maps directly to a HTML TextArea thats why you can only set text to it. The only thing you can do ist create a Grid/VerticalPanel/HorizontalPanel and put in each cell a separate TextArea.

Use a Composite wrapping a FlowPanel, put a text area and an image inside, then in CSS position the icon absolutely so it's over the text field.
I have a jtextarea that is not editable. It has some text in it. What i want is that when a user clicks in the jtextarea, (preferably single click), the entire line be highlighted, and this highlighted text be retrieved.
Each line actually has an email of the form name#emailid.com. To select the entire text would require triple clicks. I want the email to be selected in a single click. Is this possible?
Sure. Just implement you own listener and call http://java.sun.com/javase/6/docs/api/javax/swing/text/JTextComponent.html#select%28int,%20int%29 on the JTextArea.
But wouldn't a JList not rather fit your requirements?
