Jframe calls jframe

hi every body
my problem is :
i have a main Jframe with a button its name is "search", when i click on it , i want a second frame appear with a message like "wait until search completed"and the rest of search code below it when the search completed i make the second frame disapear. this is logically acceptabland easy to do , but when i execute it with this senario the second frame appear and dissapear quickly .
i do not know why inspite of the time of seach is enough to give the second frame the chance to appear .
please help
sorry for my weak language
thanks in advance

Are you sure that the end of the search is what triggers the window to close? It sounds like you are doing some thing like this:
waitFrame = new WaitFrame();
waitFrame.dispose();

Can i call a JMenuBar in a number of JFrame(s) ?

Hi ,
I've a program with a number of JFrames.
I wanted to add a JMenuBar for each frame of my program, this menu bar has the same design code and the same events code in all the program frames, so is there a way to create this JMenuBar once only & call it some how in every JFrame to load it directly instead of writing its same code a lot of times for every JFrame ?
Thanks ,

How to call a private method in a JFrame

I have a Frame which has some properties like its size, bgcolor plus other parameters, as instance variables. There is a button on the Frame with the caption : "set properties". When one clicks on that button, a new frame should appear via which a user can change the values of the parameters of the main Frame (i.e size, bgcolor,..etc). The user would input the new values in the textfields or radio buttons that are on the new frame, and then click a submit button, which has to exist on the same NFrame. How can I do that so that when the submit button is pressed, the parameters values are updated and so is the display view ?
I made it this way : I created 2 classes, the main frame and the new Frame. I made the new Frame an instance variable of the main Frame. When the user clicks the " set properties" button on the main Frame, the new Frame is shown. The user enters new values for some of the parameters and clicks submit. The parameters in the new Frame are updated. UP TO HERE EVERYTHING WENT JUST FINE. Now, there is a private method in the main frame that changes the color, size, ...etc of the main frame according to the values stored in the instance variables color, size,...etc. THE QUESTION IS: How can the new Frame display the changes after the values have been updated ? That is, how can it call the "private" method in the main class?? Should the new class be a child class of the main class to be able to access it's private methods ??

i.e I can create new jpanel and pass in handles from one to another but not back to the jFrame.
// this is sudo code
private Panel_Top topPanel;
private Menu_Panel menuPanel;
private DataPanel dataPanel;
//create new
    topPanel = new Panel_Top();
    menuPanel = new Menu_Panel();
    dataPanel = new DataPanel();

    topPanel.setMenu_Panel(menuPanel);
    dataPanel.setMenu_Panel(menuPanel);
// in each class I use this to set
public void setDataPanel(DataPanel dataPanel) {
    this.dataPanel = dataPanel;
}But I can not seam to get a handle back to the jFrame that created it.

I only need to call 1 new login screen and no new application... how can i call a
function from another java file?From a method of any class you can invoke (call) methods of other classes. I use "method" rather than "function" here to emphasise that they are much more than bits of code that do something: they have a context (the object of which they are a method).
for instance i want to call the start function of the loginScreen.java from the
testapplication.java. i don't need any new pieces, just want to be able to open the
loginscreen jframe from the test application jframe.I wondered before why that start() method was creating a new loginScreen, but leaving that aside... One way might be for the TESTapplication class to have a member variable of type loginScreen. When some method of TESTapplication wants to invoke the start() method it just does so:loginScreen myLoginScreen = new loginScreen();
// much later...
myLoginScreen.start();There is no need for the loginScreen to have its own TESTapplication member variable since, as you say. "i don't need any new pieces".
The start() method appears to next to nothing. It makes the loginScreen instance visible. But there's already a public method to do that. Perhaps loginScreen should be a modal JDialog: calling setVisible(true) will allow the login screen to do its thing and not return until it has finished (without blocking the event queue).
It's all really a bit speculative and will remain so until you break down your application into small pieces: not functions (actions), but classes (types of obejcts including the things they can do.) Each class should have a clear and documented description of what it does.

Calling JFrame seems to produce an exception with 10g

Hi all,
I have written a couple of line of JAVA to calculate the width of of some text (font dependant). While the small program works fine under windows the same source code crashes in the Oracle PL/SQL environment. As soon as the code 'new JFrame' is executed the exception is raised (the program return -1)
Is this a normal behaviour for 10g ? Do you see a workaround to get the width of strings ?
Thanks for help.

Calling modal JFrame from JFrame?? is it possible

i have created a frame and there is a button on that frame.
on push of the button i want a modal frame to open up..
i am unable to make this modal its modless by default in my code.

how to put a frame inside a Jdialog

any help ???

how to put a frame inside a Jdialog
and calling JDIalog from a button on another frame.And you can't do this either.
What you need to do is create a class that creates a JPanel, not a JFrame. In your main application (that's within a JFrame) when the JButton is pushed, create a modal JDialog (or perhaps better a JOptionPane) and place the created JPanel in the dialog or optionpane and then show. This will work, and fairly easily.
Usually even my main application is created in a JPanel (I'm trying not to subclass unless absolutely necessary), and I add the JPanel to a JFrame when I want to show this main app. Later, if I decide that I want to show the main app as a JApplet, it's a trivial thing to just create the JApplet, add my main JPanel to it, and show the JApplet. Programming this way increases your flexibility tremendously.

Hi Denis,
Thanks for the bug link you provided. I looked at the bug they were talking about, it looks similar to what is happening to me, but they were talking about Solaris and Linux. Our app runs on Windows and the report says they did not test the fix on Windows.

JFrame calling another JFrame

Hello,
I have a simple question:
2 java files with 2 JFrames in them
JFrame1(Cars.java) calls JFrame2(AddCar.java) from actionlistener.
What I think is wrong is JFrame1 actionListener:
if(ae.getSource() == CarEdit_btn){
AddCar objEditAddCar = new AddCar();
objEditAddCar.EditCar();
And JFrame2's EditCar() method:
public void EditCar(){
AddCar windowAddCar1 = new AddCar();
windowAddCar1.setTitle("Add Car");
windowAddCar1.pack();
windowAddCar1.show();
AddCarMilage_txt.setText("544");
The problem is that AddCarMilage_txt.setText("544"); doesnt update the value of the JTextField of JFrame2.
Any ideas? Thanks
Or another way to go around for me is, how do I use args[] from main inside the constructor?

read this:
http://forum.java.sun.com/thread.jspa?threadID=5199666&messageID=9792440#9792440
it has also 2 classes and updates the textfield of the other class just copy and paste the code.

Custom JPanel moves inside JFrame when Jpanel.paintComponent(...) is called

I have a custom JPanel (CompassCalculatorPanel) that is created, setup and placed within a custom JFrame (CompassCalcFrame). Calling the JFrame constructor sets this all up and makes the Frame show up. All is good with placement and drawing initially. Then when a user changes the spinner value (change the compass heading) it is supposed to redraw the arrow within the panel. It does this just fine, but on the repaint, and subsequent paints, the Panel ends up being placed in the upper left corner of the frame, rather than at the place I positioned it. I've tried saving the upper left corner placement coordinates and calling setBounds(...) before and after the paintComponent(...) method is called. This has no effect, the panel still resides at 0, 0.
boldAny help that keeps the panel in place would be appreciated!*bold*

In response to the first couple of comments made about using Absolute positioning (layout null), I took a look at the page on doing layouts, which happens to be the link you sent. I read about each, and decided that a GridBag layout would be best. So I created a new class called CompassCalcGridBagFrame and set it all up using the same components, but with a Grid Bag layout. I encounter the exact same problem.
Just FYI: I originally created this frame using the NetBeans (6.9.1) Frame form builder. By default that uses the Free Design setting, which creates group layouts for both vertical and horizontal spacing. This is where the problem first came to be. I next used the builder to create an absolute positioning frame, which had the same issue. That is when I started building my frames using code only - no NetBeans GUIs. This is where the absolute layout from scratch code started. Same effect. And now, I've created a Grid Bag layout from code, and same effect. There has to be something I'm missing overall, as this effects all of my different layout designs.
The one thing from gimbal2's previous comment is, should I be using this custom panel within another panel? I am currently adding all of the components (and in Grid Bag, the GridBag layout) to the frame pane itself. Is that OK, or should I use a generic JPanel, and have the components all within that?
Here is the code for the newest frame class (CompassCalcGridBagFrame):

Japplet is not able to call a class that extends JFrame in internet Explore

Hi
I am doing an application on Japplet.The Japplet class calls anathor class which extends JFrame.When I am running this appication on Applet Viewer it works fine.but when I am running this aplication in internet Explorer the Frame window doesn't come.What might be the problem.
Thanks
Srikants

There is no error or exceptio comming when i am running that application on Internet Explorer.Convert the html page to use the object tag instead of the applet tag.
The IE build in jre (called msjvm) cannot display JFrame since the version is
1.1.2 and it has no javax classes.
Still problems?
A Full trace might help us out:

JFrame not showing components when called method in other class

Hi everyone,
I am new to SWING,and have this little problem.
i have created a JFrame which has a button and its calling a method in another class.the result takes much more time(around 3mins) as the call involved with FTP.
My problem is , i click the button(other componetns also there),and waiting for the result.all the time my Frame doesnt show any of the components,it looks as if the components are added to it.but when the call returns.everything is OK.
Can any1 help me?
Thanx in advance
