How to save the JFrame

how we save the JFrame dynamically???????/

hiiii
i'm a student doing my project in real time video processing, wherein we plan to accept real time images 4rm the web camera. We wish to divide the main frame of our front-end into 3 parts. One will display the video coming in 4rm the webcamera & the other side of the screen(front-end) the processed video.
The third part will consist of radio buttons, textboxes,etc, which we will use to adjust contrast,sharpening,etc. the changes must happen on the video as it comes in. The original video should continue to show as normal, and the processed video should reflect the changes. This should allow us to thus compare the two.
Please suggest us some way of implementing the above using JMF. We have been able to get the video as it is captured from the webcam. However we are not able to figure out how to implement the second video screen after applying the various techniques, so that it appears as a real time video.
Any help or suggestions in this regard will be appreciated.
thanx,
Leon.

please tell me am i thinking right
about this method: setImageableArea(.....)
public void setImageableArea(double x, double y, double width, double height);
like I said, I've tried this method and it doesn't seem to do anything.
the width=the JFrame Width,the height=the JFrame Height right?actually, when printing, 72 points (printing version of pixels) = 1 inch, so to do WYSIWYG, you need width = JFrameWidth * 72.0 / Toolkit.getToolkit().getScreenResolution. Ditto with height
upper left beginningx(0)---------------------------200--------------------------------600-----------------------------------y(1000)upper right beginningyou need to do something like PageSetup.getImageableX and do Graphics.translate(x,y);
also, if your page width = 720, that = 10 inches - that's a wide page (unless its in landscape)
so if i want the JFrame To Be In The Center Of The Page I Would Choose From x=200 ,y=600 depending that frame width is 400Actually, it would be 300 - 700 in your example
Because when i tried to use:setImageableArea(200, 600, 400, 200);like the above code
no changes occurs in the printed paperYes. You need to offset the Graphics object

How to change the JFrame's titlebar's icon's context menu's font?

Hi everyone.
I want to know how to change the font of the text that appears in the context menu originated from right clicking at the icon that's all the way to the left in the titlebar of JFrames that use the default look and feel for decoration (JFrame.setDefaultLookAndFeelDecorated(true); // which uses the Metal L&F, Ocean theme).
I searched around and found nothing. I thought that I could use what I learned at https://forums.oracle.com/message/9221826, but I couldn't come up with something that worked.
Thanks in advance.t

After some more messing around, I finally made it! I like Java so much that it makes me a bit sad how hard it is to do stuff like this. Anyway, I found a method here to recursively change the font of all components from a JFileChooser, but it doesn't work on the JPopupMenu (now I know the name) that pops up from the titlebar's icon. So I messed around with that method, used some casting, and was able to change the JMenuItems' font:
public static void setSubComponentFont (Component comp[], Font font) {
    for (int x = 0; x < comp.length; x++) {
        if (comp[x] instanceof Container) {
            setSubComponentFont(((Container)comp[x]).getComponents(), font);
        try {
            //comp[x].setFont(font);
            if (comp[x].toString().contains("JMenu")) {
                for (Component y : ((JMenu)comp[x]).getPopupMenu().getComponents()) {
                    if (y.toString().contains("JMenu")) {
                        y.setFont(font);
        } catch (Exception ex) {}
I was inspired to use .toString().contains() by this thread.
I also did this with nested loops, so the path to the menu items can be seen:
for (Component a : frame.getLayeredPane().getComponents()) {
    System.out.println(a.toString());
    if (a.toString().contains("MetalTitlePane")) {
        for (Component b : ((Container)a).getComponents()) {
            System.out.println(b.toString());
            if (b.toString().contains("SystemMenuBar")) {
                for (Component c : ((Container)b).getComponents()) {
                    System.out.println(c.toString());
                    for (Component d : ((JMenu)c).getPopupMenu().getComponents()) {
                        System.out.println(d.toString());
                        if (d.toString().contains("JMenu")) {
                            d.setFont(font);
Every System.out.println() gives a hint to what should go on the following if condition, so they should be used one at a time. This doesn't work for the JFileChooser's title font though. When I have time I'll either look further into it or ask another question.
So, if someone else needs it like I did, here it is. As a tip, System.out.println() and .toString() are your friends! That's how I learned what was contained in each object, and what path I needed to take to get to the objects of interest.
Thanks anyway!

How to ZOOM the JFrame and its components ?

Hi
I could not find any solution/suggestions for this, so I am asking help.
I am adding multiple components (JLables, JtextFields and a JTable) in to Jpanel(s) and to a JFrame window and I want to add Zoom (+ or - ) functions.
I don't want to take each and every component from JFrame/ JPanel(s) and resize or repaint.
Is there any way, that you can increase and decrease the whole JFrame and JPanel's view so that the components, which are been added to them, look like their sizes are also increased / decreased?
Any suggestions or help would be appreciated.
Thanks.
Regards,
Vally.

ok...
god bless the "GlassPane"
you can take a snapShot of your frame...
draw it on your glassPane..
and just use your glassPane
to paint the image with the requested size...
in this approach you cant press a button and to things..

How to set the fix size jframe window

when I run the jframe ,the jframe window size is very small
1)how to set the fix size jframe window??
2)how to set the jframe cannot change the window size??
thx~~

1. You can set the size by calling JFrame's method setSize. There are two versions of this method: (1) setSize(int width, int height) and (2) setSize(Dimension d). Note, that when you use this method to set the frame size, you don't have to call JFrame's pack method.
2. JFrame has a method called setResizable(boolean resizable) which you can call with the argument false.
Without any ill intent, these questions are regarding something that is very easily answered by looking at the documentation for the JFrame class. I suggest to anyone working with swing to at least look briefly through the base classes they're extending before giving up. In my experience it is always more gratifying to figure things out on my own than asking someone. But please don't take this the wrong way, I respect people who seek out help in order to further their knowledge, instead of just giving up.

How to update the second JComboBox according selection in first JComboBox??

I am having a hard time to update the second JcomboBox according to the selection of the first JcomboBox. For example, the content of the first JcomboBox is {city, rent}. When "city" is selected, the content of the second JcomboBox should be set to a number of cities. When "rent" is selected, the content of the second JcomboBox should be set to a range of rent.
Since I have to detect the selection in actionperformed(), where the JcomboBoxes have been added to a Panel, and my JFrame setContentPane() to this Panel, I don't know how to update the JFrame or the Panel. I can make the old JFrame disappear and a new JFrame appear instead, but this is not what I want. I tried method update(Graphics) and removeAll(), and never made it work.
I would greatly appreciate if anyone could give me any help.

Thanks for your response. I fixed the problem in the following clumsy way:
frame.getContentPane().remove(mainPanel);
mainPanel.remove(box2);
if(box1.compareTo("city")==0)
box2 = new JComboBox(cities);
else if(box1.compareTo("rent")==0)
box2 = new JComboBox(rents);
else if(box1.compareTo("type")==0)
box2 = new JComboBox(types);
box2.setBounds(305, 30, 90, 20);
mainPanel.add(box2);
frame.getContentPane().add(mainPanel);
Maybe there is a better way, but I don't know, and I don't understand your suggestion, could you further explain it? Thanks a lot.

Resizing and/or Moving the JFrame on the Screen

Is there any way to resize a JFrame when the undecorated property is set to true.
I would like to have a JFrame that is both undecorated and resizable.
Similarly, I was also wondering how to move the JFrame on the screen if the
undecorated property is set to true since there is not Border to select the
JFrame to initiate the Move.
Thanks!

yes... setSize(), setLocation().
And if you want the user to be able to do it with the mouse, you need to add a border to the rootpane to prevent anyone adding things over the whole rootpane, and add a mouse listener to it to catch mouse click and drag events and do the calculations.
If you look at the BasicInternalFrameUI, or some thing in there should have some code that does the same thing.

Problem with the JFrame maximum size

Dear all,
I need to make my application expand to the maximum screen size when
the user first starts it. I am using hte following code:
frame.setSize(getMaximumSize());
however if my JFrame has a border layout and I have added a component at the page end
"add(new JLabel("hello"), BorderLayout.PAGE_END);"
this component is not displayed on the screen until I maximize the JFrame manually by clicking on
the default "Maximize" button at the right top corner?
Does anyone know how to get the JFrame occupy the maximum screen size where all of the
components would be visible?
