Who paints the background of JInternalFrame

Hello all,
Im new to Swing / plaf, and I have a probably simple question.
Im trying to make an internal frame that has rounded corners. Therefore I do not want the background color to fill the entire background. Actually I'd like to paint the background myself.
I have extended and installed my own BasicInternalFrameUI. In installUI(JComponent c) I call c.setOpaque(false). And would now expect to be able to control the painting of the background by overriding BasicInternalFrameUI.paint :
public void paint(Graphics g, JComponent c) {
g.setColor(Color.black);
g.fillRoundRect(0,0, c.getWidth(),c.getHeight(),10,10);
(Disregard the fact that I paint on top of the title too - this example is only to keep it simple)
But the JInternalFrame shows it's background color, and not my rect.
It seems like the only way I can change the painting of the JInternalFrame is by overriding JInternalFrame.paint :
public void paint(Graphics g) {
super.paint(g);
g.setColor(Color.blue);
g.fillRoundRect(0,0, getWidth(), getHeight(),10,10);
But that's not really look&feel...
Could someone please enlighten me? How do I paint the background of an JInternalFrame the proper way?

Painting the background

Hi everyone. I have a little question.
I'm trying to make my application draw some background images (in the HBackground) And everything seems to be ok except when the image is drawed. It appears but distorted. I first put the background and then reduce the video playing so te background could be seen. Maybe I have to reduce the video first? For reducing it I use the AWTVideoSizeControls and ServiceContext way
This is the little piece of code for painting the background
public void cambiar_fondo_imagen(String imagen) {
        HBackgroundConfigTemplate plantilla = new HBackgroundConfigTemplate();
        plantilla.setPreference(HBackgroundConfigTemplate.FLICKER_FILTERING, HBackgroundConfigTemplate.REQUIRED);
        plantilla.setPreference(HBackgroundConfigTemplate.STILL_IMAGE, HBackgroundConfigTemplate.REQUIRED);
        HBackgroundConfiguration config = planoBackground.getBestConfiguration(plantilla);
        HStillImageBackgroundConfiguration configStill = null;
        if (config instanceof HStillImageBackgroundConfiguration) {
            configStill = (HStillImageBackgroundConfiguration)config;
        planoBackground.reserveDevice(this);
        try {planoBackground.setBackgroundConfiguration(configStill);}
        catch (Exception e) {System.out.println("Excepcion: " + e);}
        if (config != null) {
            HBackgroundImage imagenFondo = new HBackgroundImage(imagen);
            try {configStill.displayImage(imagenFondo);}
            catch (Exception e) {System.out.println("Excepcion: " + e);}
     }Maybe I may change some HBackgroundConfigTemplate options? (I'm using an i-frame of a mpg as the background image)

right-click (or command-click) in the outer canvas, and watch for the pop-up menu options.

Can I not paint the background of an image?

I can draw an image just fine (I use JFrame), but I am having a big problem
I draw the image, but the image's background color gets drawn over the GUI's. for instance if I have an airplane sprite (.gif or .png), the airplane could be black but the background color of the sprite itself is white. when I g.drawImage(airplane, 200,200,this);, it displays the black airplane along with the rest of the white surrounding that is part of the sprite. I have been able to make up for this so far by doing things like painting the entire GUI white so that you cant tell, but its getting out of hand and unworkable on this new project of mine
how do I get java to ignore the background color of the sprite itself, and just draw the pixels that are NOT the background color?
if the image is a black airplane on a white background, I want to be able to just paint the black of the airplane, so it doesn't look like a retarded white square over a blue background (the GUI's background is blue)
any help is extremely appreciated :-/

Modify your sprite so it has transparent pixels rather than a background?

There is something wrong with the volumes buttons in my macbook pro, every time i pressed the one who raises the volume, it leads me to the screen where (i do not no what its called) the background is black with the date and time and a calculator.

There is something wrong with the volumes buttons in my macbook pro, every time i pressed the one who raises the volume, it leads me to the screen where (i do not no what its called) the background is black with the date and time and a calculator. However, when i lower it, my safari tab goes out of the screen. What do you guys think i should do? I'm getting very nervous.

How do I keep the paint and clone tools from removing the background on the composition?

I am trying to remove handling wires from a Muppet video. I double click on the composition (mov file) and open the layer panel. I can get the brush, clone and eraser to work just fine and everything looks great until I play the preview. I can see all my strokes on the original movie composition. For example, the white showing in the frame below.
Since I am very new to AE, I would imagine that I am missing a setting, but it seems like I have tried all of them and nothing is working.
I am using CS5, version 10. Using the normal mode and the RGBA channel on single frame. I appreciate any help you can provide. Thanks!

Hi Rick,
I am trying to remove handler wires that can be seen on Elmo. This is an
assignment for an online class. Unfortunately, I asked this question early
last week of the instructor and he has not responded. We are required to use
the clone, paint or eraser for the exercise. Thanks for the tip regarding the
CC Simple Wire Removal tool. That will come in handy in the future. The
original clip of the Muppets does have a black transparent background. I
changed the composition settings so that I could better see the wires. Some
of the wires are just over the background and some are over a part of his
clothes. I can see my strokes when I toggle the transparency grid. I will
try the clone tool on the alpha channel and see if that works. If that is not
what I should be doing, please let me know. Thanks for your help.
I'm not really clear on what you are trying to do. If you're painting on RGBA
and you paint with a white brush you will end up with a white stroke on the
layer. All channels will be white.
Â
If you're painting with a white stroke using Alpha then you will paint white
on the alpha channel so there will be nothing changed on the layer.
Â
If you are painting with a black stroke using Alpha then you will paint a hole
in the layer which will allow the layer below to show through, but if you're
painting on RGB or RGBA then you'll end up with a black stroke on the image.
Â
If you want to paint out the wires then you must either use the clone tool or
make the brush the same color as your background. It looks like you have a
cream colored background so your paint tool must be the same color. If you
have wires over any other color, say over the body of one of the Muppets, then
you must carefully use the clone tool. Your screenshot looks like you're just
painting with a white brush. I'm assuming that your Comp BC color is white
(not usually a good idea) and that there is really no hole in your footage.
You can check that out by clicking on the Toggle Transparency Grid or by
dropping another layer below your footage.
Â
Another option to remove the wires would be to use the CC Simple Wire Removal
tool. It works amazingly well on some shots.

Paint an image in the background of the JDesktopPane?

I need to show an image in the background of an multidocument Java application (Swing based). It's not possible overwritting the method "paint" of the class "JDesktopPane" (appear some problems). Can anybody help me, please? Thanks a lot.

You have to override the painComponent method not paint.
JDesktopPane desktop = new JDesktopPane(){
    Image im = (new ImageIcon("background.jpg")).getImage();
    public void paintComponent(Graphics g){
        g.drawImage(im,0,0,this);
};I hope this helps,

The problem of the Canvas and JInternalFrame

I have some problem with the Canvas and JInternalFrame, my application contains serval internalframes and each has one canvas, but i found that canvas is at the top z-order of the window. so it result in that the canvas is at the same z-level, which confuse very much.
who can help me with this problem, thanks.

I think the problem stems from mixing AWT and Swing components (non-lightweight and lightweight)
if the reason you are using a canvas is for the paint method; do away with them and just use a JPanel (which you can use the paint method within)
hope this helps?!

Hi can anyone help with this issue regarding my wireless magic mouse? When im on google chrome and scrolling down the page i always have youtube running in the background but the audio cuts/spits/pops can anyone help me with this?

The figures you mention only make sense on your intranet. Are you still using the same wireless router. The verizon one is somewhat limited as far as max wireless-n performace. For one thing it only has a 2.4 radio. I like many people who wanted wireless-n performance before they even added a wireless-n gigabit router, have my own handling my wireless-n network.

I want to plot a waveform chart where I have a constant slope(defined by me) and new data is plotted over the chart with the defined slope already in the background.

I want my chart to have a constant slope already plotted before it continues to start plotting the real time data.. so that I can compare my new data point to point with the ideal slope that i already have in the background
Solved!

Since your graph is refreshed every time you go through the loop anyway, just set up the constant/reference array before the loop and feed it into the graph. That way you'll also have a full X-axis (and a Y-axis which at least includes all the reference data) for the graph already set up.

How do I change the background color of a BufferedImage?

I have a program and basically what I am doing is drawing on a BufferedImage object and then painting that BufferedImage object onto the panel. By default, the background is black and it draws in white. I am easily able to change the colour for drawing by doing g2.setColor(Color.RED) for example where g2 is the Graphics2D object created by image.createGraphics(). I tried g2.setBackground(Color.WHITE) and that did not work.
If more information is needed, just ask.
Any help in changing the background colour of the BufferedImage would be greatly appreciated!
Thanks in advance!

Here is a mini-code with comments explaining my trouble:
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.image.BufferedImage;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class TestBuff extends JPanel
    Graphics2D g2;
    BufferedImage image;
    public TestBuff()
        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLocationRelativeTo(null);
        frame.setSize(800,800);
        frame.add(this);
        frame.setVisible(true);
        image = new BufferedImage(800,800,BufferedImage.TYPE_INT_RGB);
        g2 = image.createGraphics();
        g2.setBackground(Color.RED); // I am setting the background colour here
    protected void paintComponent(Graphics g)
        g.drawImage(image, 0, 0, g2.getBackground(), this); // Why is this black instead of red?
    public static void main(String[] args)
        new TestBuff();
}

Can a java program be run in the background?

Hi all,
Can a java program be run in the background without the user being aware of it? I need to make a program that continuosly monitors a pc at regular intervals and runs at all time. It should be hidden(shouldn't display on the screen while running) from the user, and also, can it be run as a system file so that even if a user checks he/she would think of it as a system file?

I'm the administrator of all the computers. Then as I said there are commercial applications that do that.
Presumably you expect a problem now. And implementing an acceptable solution is going to take you months. Because not only need to 'hide' the application, you also need to set up all the monitoring and logging capability. And the first will require quite a bit of JNI work along with testing (in particular as it could interfer with existing applications on the users computers.)
I need to
install the software in all the machines and i want
that the users who use the machine should not be able
to close the program through the task manager. If the users have admin rights then they can terminate a windows service.
And if they don't have admin rights then you can simply turn off the ability to install anything.
I want
to know what the resources of the computers are and
that if anyone has added a resource to it or
not(attaching a flash usb thumbdrive etc). Lots of JNI.
