How to make a slide bar that controls opacity

I'm trying to figure out how to make a slide bar that would control opacity. If I were to take to pictures on top of each other, the slide bar would control the opasity of the top image. Thanks

can you make a slider that controls anything?  if so, what's the range you can control?
ie, when the slider is at one extreme it causes some object to have value1 and when it's at the other extreme the object has value2.  what value1, value2 can you handle?

    really it's only a matter of using startDrag() and stopDrag()
    methods, and then polling the position of the 'puck' in relation to
    it's travel area, converting it to a percentage and using that
    value to effect whatever you want.

  • How to make a slide show that will play on a TV?

    I have a
    collection of pics that I have used the slideshow module t
    o create a slide show and it works great on my PC. How do
    I create one that I can burn to a disk and play on a TV?
    Do I need to purchase
    something else or will Lightroom3 do what I need? The slideshow that I created will play on other computers but, when I put it in a dvd player for the TV it says there is no disk in it. I have tried 4 different players. Am I missing something?
    I would be very gratefull for help with this!

    Alternatively, you can export a H264 mp4 from the slideshow module, dump it on a memory stick (or plain DVD) and stick it in the TV or your BluRay player
    Not all Blu-ray palyers can play MP4 container video files. So this may, or may not work depending on your Blu-ray player's capabilities. ALL Blu-ray players will play H.264 AVC HD video with .MTS file format, but Lightroom 3  does not offer this as a slideshow export option.
    See the 'Overview' section here for more information on the file system and folder organization:

    The folder structure when using USB and SD media is different than DVD media! More information here:

  • Is their any tutorials on how to make a navigation bar with drop downs in Dreamweaver CC now ?

    Is their any tutorials on how to make a navigation bar with drop downs in Dreamweaver CC now that they do not have the spry option?

    Preran, why wouldn't Dreamweaver include it's own menu/navigation bar widget?
    I can't answer on Preran's or Adobe's behalf, but I think you'll find at least part of the answer here: http://wiki.jqueryui.com/w/page/38666403/Menubar
    Adobe decided to discontinue development of Spry in August last year, and Dreamweaver CC made the switch to using jQuery UI widgets and effects. One reason for dropping Spry was that it failed to work correctly in some browsers. Judging from the fact that the jQuery UI menubar is now "on ice", creating a flyout menu that works reliably across all devices is proving more difficult than originally envisaged.
    Because all other widgets in Dreamweaver CC use jQuery UI, it's a reasonable assumption that Adobe hoped the jQuery UI menubar would be ready in time, but it wasn't.

  • How do I restore tool bar that has history, bookmarks, tools, view ans edit on it?

    Some how I deleted the tool bar that contains following items - File, Edit, History, Bookmarks, Tools, Help.
    How do I restore this tool bar?

    Your '''menu bar''' is hidden. Press F10 or Alt on you keyboard to make the menu bar temporarily appear. Then go to Tools > Toolbars and select the menu bar to make it permanently appear.

  • How to make a Java program that recognises a function of two variables...

    How to make a Java program that recognises a function of two variables to assign values to that?
    First I will give an example and then do the question.
    Ex1.
    We have any function, eg.y = x ^ 2 + 1 (read 'y' equals 'x' high to the square), a function of the second degree.
    To build the graph of this function attach values to 'x' to find the values of 'y'
    And thus mount the pair ordered (x, y) which represents a point on the Cartesian plane.
    Assigning values to 'x' 'we can build up a table that gives us the pairs ordered:
    We can use any numbers, but arfer interval [-3.3]
    X | y = x ^ 2 + 1
    -3 | Y = (-3) ^ 2 +1 = 10
    -2 | Y = (-2) ^ 2 +1 = 5
    -1 | Y = (-1) ^ 2 +1 = 2
    0 | y = (0) ^ 2 +1 = 1
    1 | y = (1) ^ 2 +1 = 2
    2 | y = (2) ^ 2 +1 = 5
    3 | y = (3) ^ 2 +1 = 10
    We then ordered the pairs:
    (-3.10), (-2.5); (-1.2), (0,1), (1,2), (2,5), (3,10)
    Tabem that can be represented by a table:
    X | y
    -3 | Y = 10
    -2 | Y = 5
    -1 | Y = 2
    0 | y = 1
    1 | y = 2
    2 | y = 5
    3 | y = 10
    Now I begin to explain my doubts.
    See this program:
    Ex2
    * To change this template, choose Tools | Templates
    * And open the template in the editor.
    Encontrando_o_valor_de_y package;
    * @ Author des Soldat Gottes
    Import javax.swing.JOptionPane;
    Public class (Main
    * @ Param args the command line arguments
    Public static void main (String [] args) (
    Int x, y;
    String x1;
    X1 = JOptionPane.showInputDialog ( "We have the function y = x + 1 \ n" +
    "Assign a value for 'x',"); / / receives a value for the function y = x + 1
    X = Integer.parseInt (x1); / / tranforma String in int
    Y = x + 1; / / receives the value of 'x' and calculates' y '
    JOptionPane.showMessageDialog (null, "The value of 'y' is: \ t \ t" + y);
    / / Displays the value of 'y'
    System.exit (0);
    We see that the program receives above a value for 'x' and replaces the function contained in the program, y = x + 1, and so is the value of the variable 'y'.
    In: x1 = JOptionPane.showInputDialog ( "We have the function y = x + 1 \ n" +
    "Assign a value for 'x',");
    The entry is a number and that number is assigned aa ja existing function in the (y = x + 1).
    The question is: would it be possible to come to a function?
    Ex: the program ask: DIGITE THE FUNCTION?
    The USUARIO DIGITARIA A FUNCTION ANY, TYPE: y = x ^ 2 +1
    The program would recognize the function and give numerical values to that function as Ex1, at the beginning of this text.
    And then to find the values of the x and y launch a table.
    It would be possible that?
    By invez of entering with a number so that the program sustitua a function ja existing as Ex2, seen above, entering with a function quaquer (type: y = x ^ 2 +1) for the program atribuisse values to that function and then create a table of values as Ex1.
    I hope it has been easier to understand my doubts now.
    Thank you for your attention!
    God bless!

    Thanks for the explanation, could understand what fly said.
    But as it applied to a program?
    How to create a program that recognizes that the entry coefficients?Are you asking about how to parse out the coefficients from the string "3x^4 + 4x^3 - 8x^2 + 5x^1 + 2x^0"? If you define the format to strictly follow that example, this should get you started:
    Strip out the spaces
    Split the String on "x^"
    That should give you [3, 4+4, 3-8, 2+5, 1+2, 0]
    Split each resulting String on "+ | -", preserving the operator as a token so you can apply the correct sign to the coeff.
    That should leave you with [3, 4, +, 4, 3, -, 8, 2, +, 5, 1, +, 2, 0]. Every other number is a coeff, the rest are the degrees.
    You can strip out the +, since those coeffs are already positive, and strip out the - after negating the following number. This is all assuming that you have to write this yourself. There is no doubt already a library or 5 out there that does this for you.

    I want to make a dvd menu in iMovie because i don't have IDVD and can't find anywhere to download it?
    For making DVDs I would recommend iMovie 06 and iDVD 09 both readily available on Amazon or eBay.  Shop for iLife 06 and iLife 09.
    You can make menus and chapters with any version of iMovie except the latest one. There's nothing wrong with iMovie 11 either but I prefer iMovie 06.
    By using iMovie 06 and iDVD 09 I make DVDs with professional moving menus with very little effort. They look almost as good as Hollywood.

  • How to make my SLIDER control the movement of animations: ( fast & slow)

    hello!
    i wanna do water dropping animations. using a slider, to controlled how fast and slow the animations can be.
    please help me!!!

    I need help about controlling my animations with slider.
    I already know about slider & water dropping animations, but how to make this 2 things interract.
    Right now i have slider and water dropping animations, but when i scroll my slider up and down, my animations still with the same speed.
    In my opinion, i think, i need to make one func/method that take var from slider and transfer it to water dropping var(controlling the speed of anim...).
    eg: (coding)
    //class bla...bla...bla...
    JLabel sliderValue = new JLabel("Value = 25"); // slider var
    JSlider sliders = new JSlider(JSlider.VERTICAL, 0, 50, 25);
    WaterDropPanel drop = new WaterDropPanel(); // waterdropclass
    JButton start = new JButton("Start"); // start anim...
    JButton stop = new JButton("Stop"); // stop anim...
    //waterdrop class...
    class BulatanPanel extends JPanel implements Runnable
    private Thread runner;
    int yPos = -20;
    int yMove = 4;
    void playAnimation()
    if (runner == null);
    runner = new Thread(this);
    runner.start();
    void stopAnimation()
    if (runner != null);
    runner = null;
    public void run()
    Thread thisThread = Thread.currentThread();
    while (runner == thisThread)
    yPos += yMove;
         if (yPos > 310)
         yPos = -20;
    repaint();
    try
    Thread.sleep(10); // var controlling the speed of anim...
         catch (InterruptedException e) {}
    public void paintComponent(Graphics comp) {
    Graphics2D comp2D = (Graphics2D)comp;
    comp2D.setColor(Color.black);
    comp2D.fillRect(0, 0, 250, 240);
         comp2D.setColor(Color.red);
    comp2D.fillOval(110, yPos, 20, 20);

  • How to make the slider longer?

    Hi,
    I want to add a slider in my code, but the slider is too short to choose the number.
    Could anyone tell me how to make it? Thank you!
    The following is my code.
    slider1.setMin(0);
    slider1.setMax(100);
    slider1.setValue(10);
    slider1.setShowTickLabels(true);
    slider1.setShowTickMarks(true);
    slider1.setMajorTickUnit(10);
    slider1.setMinorTickCount(10);
    slider1.setBlockIncrement(1);
    slider1.setLayoutX(50);
    slider1.setLayoutY(20);

    This seems fine to me. Can you explain more what the problem is you are seeing? If you want the slider to be longer, you can manually size it (set the prefWidth, as in the following example). If that is indeed the problem, then I would suggest you look into one of the layout panes shipped with the platform which will help with making sure it is resized as you would expect.
