Sacha had it right with moving a picture control. I don't think you need to make your radar control transparent though.
Here's a version of your code with a couple of planes (read from JPEG files) flying across it. You may need to change the path constant on the diagram depending on where you copy these files.

    hey there Greg & welcome to Discussions.
    connect the projector to the Mac using the appropriate adaptor & cable, open System Prefs. > Displays > Detect Displays > Gather Windows. set rez for the projector & turn off Mirror. that's how you play your slideshow "through" the projector.

    Can u talk about this how can make this code with java?

    The author of this application says this maked by Java Swing.
    My Question is:
    What is Java Swing?
    It's easy to make this app?
    What API/Component needed for export video to MP4 Format like this application?
    How can make a similar application for education purpose with Java.

    but impossible in nothing bro, Yea, that's what Aleksey Vayner claimed and he didn't do so well.
    I need to know about swing and start to work with java to develop this software and if I need some help I ask here.Clearly yes. You also need to make simple programs and practice for a long time before you're gonna be able to write a screen recorder with MP4 output.
    I try to develop this before 3-4 years ;)I guess 3-4 years is a realistic goal, if you really concentrate on learning Java.

  • How to make a big screen PLAY button for FLV which will fade away after the movie starts?

    I wanted to make play button. Kind of this huge one in the middle of the screen as users used to see on YouTube.
    Here is the code for it which seems to work:
    play_btn.addEventListener(MouseEvent.CLICK, onClick_Play);
          function onClick_Play(event:MouseEvent) :void {
      SWF_flv2.play();
    The problem is it doesn't dissapear once the video plays. How shoudl it be done, the whole video has to go to another frame with no play_btn on it or there is a code which can make it fade away?

    The FLVPlayback component can be set to use any number of controls for the video playback. You should use those for playback control once the video has started. If you do want to create all of your own custom controls, here's an Adobe tutorial on the FLVPlayback control structure: http://help.adobe.com/en_US/as3/components/WS5b3ccc516d4fbf351e63e3d118a9c65b32-7f00.html

  • How to make a splash screen

    Hello everyone,
    I am trying to make a kind of splash screen.
    I use JWindow for this and it works well.
    My problem is, that I need to make the background of the screen "non-opaque". So only the image I add will be shown, without the background rectangle.
    I search for something like setOpaque(false) method in class JButton.
    But there is no such method for this class.
    I would be very happy if you could help me.

    I tried this,
    but it does not help. The background is being shown.
    import javax.swing.*;
    import java.awt.*;
    public class SSB extends JWindow
         public static void main(String[] args)
              new SSB();
         public SSB()
              super();
              this.setBounds(20,20,300,300);
              MyContainer c = new MyContainer();
              c.setOpaque(false);
              this.setContentPane(c);

  • How to Make a dynamic screen show after Logging Into Windows

    I have been asked if it possible to get a Screen (Web page?) to show after people log in and before it takes you to the desktop?
    what the requestor wants is basically, you log in onto your laptop, and then a screen will appear with several choices for you to choose from and you can click the item you want and then it will open...
    the thing is the requestor wants to have the company logo and specifc items in the screen...yes, I realize this sounds like the tiles that Windows 8 has).... but it also is similar to a web page...
    the person mocked up what they want in Access...
    is there a way I can do this with a .bat or group policy....

    Hi,
    What you have described looks like some kind of software management system.
    According to my knowledge, we could configure group policies/scripts to run programs at start up or user logon, but this won't offer a list for the current user to choose, or might we consider to create a software list program which will be triggered
    by a logon script, after the selection then make a call to the wanted program?
    Best regards

  • HOW TO MAKE PICTURE ON SCREEN VERTICAL

    The w2207 can be used horzonaly or verticaly.  I am setting up 2 screens on one computer, Dell OPTIPLEX GX620,  (windows 7 / 64-bit).  One horizontaly one vertical. I have 2 issues: First issue: Windows7 does not recognise screen 2 on control panel.  Screen 2 duplicates Screen 1.  I have a poweredsplitter to divide up the audio/video for additional screens.  Screen 1 and Screen 2 are connected to outputs. A thirdoutput is connected to a tv/monitor.  All screens have the same picture at the same time.  My guess is I would need toconnect Screen 2 by another means so the Windows7 will recognize it??  Maybe use DVI or HDMI don't know, asking? Second issue, I can mechanically rotate the screen from horizontal to vertical, but the text/picture stays horizontal.My View Sonic changes to match the screen position like a cell phone. The HP does not! NOTE:The View Sonic is 15 yrs. old.  Need to know how to match text/picture to screen position. DVO33308

  • How to make prints match screen view?

    After a support call, I've lowered the brightness on my imac OS 10.6.8 but the prints are darker than ever.
    I've calibrated.  The printer is an Epson 4900.  Photoshop is managing the colors.  I did not download the no color management app.
    any ideas?

    Generally speaking, you may want to learn all about color-management, calibrate and profile your equipment, and make sure you set and use color-management preferences and settings appropriate for your needs for your display and printer.
    Most color matching problems are rooted in the fact that the display monitor is not set to display your colors accurately.  There is equipment you can use, but a really rough, poor-person's way to get started (or for use in the interim) can be to print an image, then adjust your monitor to make it look as close as possible to your print.  Then when you edit your images you'll be preparing them for proper printing.  This may involve changing settings on the monitor itself or in the display driver.  But I caution you that you many never get things consistent and right without getting your head around what good color-management is all about.
    Unfortunately, because of the complexity of the realm, it's proven near impossible to teach color-management one post at a time on a forum, but there are some good references out there.  One of our members here, Gary Ballard, has published some good "getting started" info.
    Good luck.

  • How to make PowerBook remember screen layouts from small screen to Cinema

    I'm using a 23" Cinema Display with my G4 Powerbook. But I often disconnect the display if I need to take the Powerbook with me around the office.
    When I do this, I have to reposition all my windows - finder and apps - where I want them on the small screen. Then, when I reconnect to the Cinema Display, I have to reposition them all over again.
    Some apps seem to do this fairly well themselves - like Photoshop and InDesign - but others don't.
    Is there some way for me to get the Mac to remember the positions of all the windows in each configuration, so I can just switch between them... a bit like the "Location" (under the Apple menu) does for my network settings?
    Thanks for any advice.

    I don't think that you'll be able to use the HDMI port - I don't think!
    Rather, what you would need is a Thunderbolt/Mini DisplayPort to VGA (if that's what the monitor has) adapter -> http://www.monoprice.com/Product?c_id=104&cp_id=10428&cs_id=1042802&p_id=5107&se q=1&format=2.
    Good luck,
    Clinton
    P.S. Does your monitor have any other input ports? DVI would be best.
