How to make JTextFields clickable?

I posted a similar question a year ago, but it was not really well written and I didn't get an answer I could work with. Now I stand in front of the same problem. I got a JPanel (my content pane), where a MouseListener is implemented.
Everywhere I click, I get the exact coordinates of my mouse click. Except my JTextField components. When I click on those, the MouseEvent isn't even triggered. H
ow do I do this, so my mouse clicks on those will also call the mouse event?
Tried: setEnable(false) and setHighlighter(null)

Sorry thought I fixed the X/Y problem.
The X/Y problem simply means you are telling us what your attempted solution is without telling us what your requirement is. We can't suggest a different approach if we don't know what you are trying to do.
I want to open a menu,
Now we know what the requirement is.
The solution is to add the MouseListener to the text field, not the panel. If you have the same popup of the panel and the text field, then you still need to add the listener to both the panel and the text field.
You can do this in one of two ways:
Read the section from the Swing tutorial on Bringing up a Popup Menu for a working example.
Note the above tutorial is a little old, you can also check out the setComonentPopuMenu(...) method of the JComponent class. This approach will create the listener for you.

JTextPane insert component, faulty vertical alignment

I have a JTextPane, into which I need to insert a JComponent. I'm using
JTextPane.insertComponent(Component)
The item is indeed inserted, but the vertical positioning is too high. Instead of having the bottom of the component aligned with the baseline of the current line of text, the component is way above that position, blocking out/over-painting lines of text appearing above.
I have tried calling setAlignmentY(float) with various values, on both the inserted component and the JTextPane, but it doesn't affect the behavior at all.
My guess: there seems to be some state inside my JTextPane or its Document that I need to be changing. But I don't know what it is.

Have you tried calling setSize(width, height) on the JComponent before you insert it into the JTextPane? It should work for most components.

I know, this is a pretty old question, but your approach of using setAlignmentY is totally correct. Don't know what code caused it to not work, but the javadoc of JTextPane.insertComponent(Component) says the following about the alignment:
The component is placed relative to the text baseline according to the
value returned by Component.getAlignmentY. For Swing components this
value can be conveniently set using the method
JComponent.setAlignmentY. For example, setting a value of 0.75 will
cause 75 percent of the component to be above the baseline, and 25
percent of the component to be below the baseline
So using textPane.setAlignmentY(1.0f) has the desired effect.

I ran into the same problem and could not find a solution using JTextPane or JEditorPane. But I was able to use JavaFX/WebView/WebEngine/JFXPanel. You will need to update to Java 8 (JDK 1.8). I made my own class HTMLPaneType, an extension of JFXPanel, and use HTMLPaneType in place of a JTextPane.
A JTextPane requires adding a HyperlinkListener if you want to respond to href clicks. HTMLPaneType requires adding a listener if you want to NOT respond to href clicks or to respond differently. In my case, I wanted to launch an external browser on an href click. I was able to do that with both the JTextPane and the extended JFXPanel. See also

Lightweight Component over Heavyweight Component problem

The code pretty huge and involves a lot of different class/methods:
But here is the gist:
There is a main frame : A_Main
Selecting something in the main frame A: opens a JDialog B_Dialog
This B_Dialog has a JPanel on it: C_Panel
This C_Panel comprises of a textfield and a button
On clicking on the textfield/button: opens a tooltip and another JPanel: D_Panel
Now, the problem is:
1) The tooltip overflows the size of B_Dialog and therefore gets truncated
2) D_Panel however; even if its outside the boundary of B_Dialog gets displayed fully
2.1) There are some texfields and drop down menus in this D_Panel
2.2) The mouse events function correctly in this D_Panel items (drop down menus)
2.3) But Keyboard events do not function correct (Textfield)
I would be glad if you could help!
Thanks!

This can only be done in newer versions of the JDK.
See, Mixing Heavyweight and Lightweight Components.

Now, when I try to enter something in the JAR JPanel's text field, I am not able to do so as this pops out of the border of the main JDialog that contains it.
Add a JScrollPane around the JPanel, and allow it to expand both horizontally and vertically. If this doesn't work, you may need a customized Layout Manager, or use one of the default ones like GridBagLayout.
Also, you'll need to gain focus before you can enter text, but that doesn't seem to be the problem here.

In Swing, what is the best listener to use in a textarea

I am trying to change the font of the text in a textarea in Swing. Which listener should I use on textarea to trigger an action that lets the program initiate the font code.
All the examples have all the swing in the same class which lets you access the textarea directly, but I have multiple classes; I know I can pass the textarea in and in and in, but this is sloppy.
I just cannot figure out which listener to initiate.

I am trying to change the font of the
text in a textarea in Swing.
Well a JTextArea can only have a single Font, so if you want to change the Font you would have some other component, maybe a "Change Font" button that you would click. In this case you would add an ActionListener to the button to change the actual Font of the text area.
If you actually need to change the Font on selected pieces of text, then you also can't do this with a JTextArea. You would need to use a JTextPane. Read the JTextPane API and follow the link to the Swing tutorial on "Text Component Features" for an example of changing attributes on selected text. In this cause you use Actions provided by the editor kit.
So basically you need to read the Swing tutorial to find out the basics of using Swing components.

If you're listening to the textarea, then it would depend on how many different ways you want the user to be able to change the font of what they are typing.
You could use MouseListener if you want them to be able to change the font on right click/etc... or a KeyListener if you want to listen for a series of keys.

Swing: Adding listener to a component and ALL its decoration?

Can I add a listener (let's say MouseAdapter) to a Swing component
and all it's internal decoration components?
So that when a JInternalFrame is moved by the mouse
(by dragging its window title bar), it would give me following events:
mousePressed event,
mouseDragged event,
mouseReleased event.
Currently, I receive none of the above events when dragging
JInternalFrame.
I hope there is some standardized solution, but I couldn't find any.
EDIT:
Some people suggest using ComponentListener, but that wouldn't do for
me. I need to know, when the user stops dragging (mouseReleasedEvent),
not when the component moves.

Yes, you can add a listener to all a container's components. getComponents and add the listener. You should be able to manage to do this recursively. You can also use ContainerListener to check for adding and removing components.
However, MouseListener and MouseMotionListener behave strangely in that the event normally bubbles up to the parent, but does not do so if a listener is present (how is that for hopeless design?).
Your choices are:
Recursively adding listeners (bad, see above)
Adding listeners to specific components (fragile)
Adding a "glass pane" (a messy hack)
Adding an AWTEventListener to Toolkit (requires permissions)
Pushing an EventQueue and checking through events (doesn't work of Opera and Safari apparently; stops system copy-and-paste and applet dragging from working)
Use ComponentListener?

I found out how it could be done, but something tells me, it's a dirty hack ;)
Well, it works, but who can give me the guarantee that it works everywhere?
// ctor goes here {
InternalFrameUI thisUI = getUI();
((BasicInternalFrameUI) thisUI).getNorthPane()
.addMouseMotionListener(new MyMouseListener());
// }
NorthPane turns out to be the window title bar.

You should probably use a MouseMotionListener instead of a MouseListener.

In the JInternalFrame API documentation, it says:
Generally, you add JInternalFrames to
a JDesktopPane. The UI delegates the
look-and-feel-specific actions to the
DesktopManager object maintained by
the JDesktopPane.
Maybe you should add your listener to the JDesktopPane.

MouseListener/MouseMotionListener wont detect when dragging a JInternalFrame. Your best bet here to detect movement is using a ComponentListener on the JInternalFrame itself.
