glasspane

[This question is in relation to this question ] Setting : I have this home-crafted "editable label" component which looks like a label, but when you click it, it turns into an editable field, allowing you to edit it. You can hit Esc to cancel, or Shift-Enter to OK your edits - or click the respective buttons beneath the editable field. The challenge : When you go into this edit-mode, I want the rest of the UI to be completely blocked: You shall either cancel or OK the edit before being able to do anything else.

By input elements I mean things like JSpinners and JComboxBoxes. My glasspane is passed a JPanel containing JSpinners, JComboBoxes and for the most part, JLabels. The glasspane has a MouseListener attached. The surprising thing is that mouseEntered is called upon the mouse cursor leaving the input elements and hovering over the other parts or empty space of the JPanel! Is this normal behaviour? How can I get the input elements to be considered part of the JPanel for Glasspane purposes? Here is a screenshot of my UI with its input elements and jLabels. Here is an example piece of Code: import

Some kind of GlassPane as it's known for Java-Windows, but full screen. Then I'd like to draw on this window. Is this somehow possible with X11? My first attempt was ignoring all events, simply copy the image from the root window using XGetImage() ... But first of all, this is quite slow as the window would need to be full screen. XShmGetImage unfortunately isn't an option here. For sure, this window wouldn't need any decoration, but that isn't a big

I am trying to achieve the following http://www.qksnap.com/i/3hunq/4ld0v/screenshot.png I am currently able to draw rectangles successfully on a semi-transparent glasspane background using the following code: protected void paintComponent(Graphics g) { Graphics2D g2 = (Graphics2D) g; g.setColor(Color.black); // black background g.fillRect(0, 0, frame.getWidth(), frame.getHeight()); g2.setColor(Color.GREEN.darker()); if (getRect() != null && isDrawing()) { g2.draw(getRect()); // draw our rectangle (simple Rectangle class) } g2.dispose(); } Which works great, however, I would love to have the

I have a calculator application in java swing, which is working properly with mouse click input. Now I want it to read input using keyboard button stroke. I had heard about the glass pane in java tutorial, but i need to know any other simple method to meet the requirement.
