Disabling JavaFX ComboBox input

How do I disable input on my editable Combobox? (Well, actually JFoenix JFXCombobox but it's basically the same apart from it's appearance)
setEditable(false) would disable keyboard input on the Combobox but the list would still appear
setDisabled(true) would disable whole Combobox but I want user to be able to focus Combobox so he can copy it's contents if necessery.
Why do I want it like that? In my forms user must first click edit button to be able to change stuff.

Basically, the method ComboBox.setEditable adds/removes an Editor to the ComboBox which can be retrieved via ComboBox.getEditor()
To keep the TextField (to copy from) but disable user-input, simply set the editable flag on the underlying TextField:
private ComboBox<String> myComboBox;
[...]
myComboBox.setEditable(true);
myComboBox.getEditor().setEditable(false);
EDIT:
As #jewelsea said in a comment below, you can hide the list as soon as the user requests to open it:
myComboBox.setOnShown(event -> comboBox.hide());
I think it would be "cleaner" to disable the button which opens the dropdown but unfortunately I have not yet found a way to do that.

Java Text Field background text that disapears when clicked

As you can see in the title i dont know how to make a java text field with text in the background that disappears when you click on it.
So theres a textfield that says "username" and when u click on it the username disapears and you can type in your password. Is it possible to do this without a new class?

my suggestion is to use swingx library and use JXTextField. so you can set the text using setPrompt method.

Hyperlink in J2ME

How I create hyperlink in J2ME?
After click the string item J2ME has to open website in system web browser.

See the same discussion on nokia forum. It will helps you.

Better create your own Button component by extending Item class and overriding paint to draw text with specified font and underlined and also you can add Action listener to it so that you can perform action
usable in forms too.

you need to use Platformrequest method to launch link in webBrowser .
Just check string is valid web address or not.

hyperlink in java

Is there any method to create clickable hyperlink in JTextArea in Java?

One way you can do it if you absolutely want to use the jTextArea is to get the User MouseClick(x,y) location and then handle from there.
However, the easier way out would be to use a JEditorPane. Maybe this link will help:

GWT hyperlink problem

i am using GWT Hyperlink for Click handling.I used rpc for showing the records in a dialog box by clicking on that link.but it is moving to home page immediately and showing the dialog box there.Please suggest me the solution for this problem.

Hyperlink should be used in combination with History (http://code.google.com/intl/nl-NL/webtoolkit/doc/latest/DevGuideCodingBasicsHistory.html) changes and not for click handling alone. When using Hyperlink the History token is updated, which will probably trigger the History change which will direct to the homepage, Next the click is handled which shows the dialog
EDIT:
Just as David mentions it's better to use the Anchor widget. Because Anchor is a native html element A, it's usability is better over using a span or div.

I concur with Hilbrand, but recommend anchor tags in such cases.
<g:Anchor name="whatever">Click me</g:anchor>

For this case I would suggest you to use CustomButton instead of HypherLink. For that custom button give some styles to look like a hypherlink. If you use label you cannot focus using keyboard.
Use hypherlink only if you are planning to give history support.
