Public Shared Sub main

I'm working on java for the last 6 months... But I'm still confused public Shared Sub main (args [] method) of channels.
Can anyone suggest this topic in a practical and detailed way? It would be appreciated :-)

Manon says:
I read that the JVM is responsible for loading the class who knows the 'main' method (the program entry point). Right?
If this is the case, then when we use private or protected instead of public, why he gives runtime error? While I think that it must produce the error in compiling.

As regards to Java language is, main() is just another method like any other. There is nothing special about this. Is the Java runtime that exactly looking for public Shared Sub main (String []). The language and the compiler do not know or care anything on this subject.

I suspect that this is your problem:

I suspect that if you did as I suggested on the other Thread and put a breakpoint in the constructor of MyScreen, you'd have foiund, this creates a second instance.

I hope that you can take it from here.

You actually spend "autostartup' as a parameter?

How can I do to block the main thread when to display a dialog box
I have a problem to block the user interface main thread when to display a dialog box (the dialog was created by the main Application), and when the dialog box is closed, the main Application can go to the next step.
Here is my code:

SerializableAttribute public class TitledPaneExample extends Application {}

I'm also interested in how to do this without the use of a step.

But, if you are ready to use a step for this, you can create a useful first step (without borders) with its owner being your current stage. Then, you can call the function showAndWait on stage that allows to block the thread of your application. For example, I implemented a DialogStage like this:
```
package hs.mediasystem.util;

import javafx.animation.KeyFrame;
import javafx.animation.KeyValue;
import javafx.animation.Timeline;
import javafx.event.EventHandler;
import javafx.scene.effect.ColorAdjust;
import javafx.stage.Modality;
import javafx.stage.Stage;
import javafx.stage.StageStyle;
import javafx.stage.Window;
import javafx.stage.WindowEvent;
import javafx.util.Duration;

public class DialogStage extends Stage implements Dialog {

  public DialogStage() {
    super(StageStyle.TRANSPARENT);

    this.setTitle("MediaSystem-dialog");

    initModality(Modality.APPLICATION_MODAL);
  }

  protected void setParentEffect(Stage parent) {
    ColorAdjust colorAdjust = new ColorAdjust();

    Timeline fadeOut = new Timeline(
      new KeyFrame(Duration.ZERO,
        new KeyValue(colorAdjust.brightnessProperty(), 0)
      ),
      new KeyFrame(Duration.seconds(1),
        new KeyValue(colorAdjust.brightnessProperty(), -0.5)
      )
    );

    parent.getScene().getRoot().setEffect(colorAdjust);

    fadeOut.play();
  }

  protected void removeParentEffect(Stage parent) {
    parent.getScene().getRoot().setEffect(null);
  }

  protected void recenter() {
    Window parent = getOwner();

    sizeToScene();

    setX(parent.getX() + parent.getWidth() / 2 - DialogStage.this.getWidth() / 2);
    setY(parent.getY() + parent.getHeight() / 2 - DialogStage.this.getHeight() / 2);
  }

  @Override
  public final void showDialog(final Stage parent, boolean synchronous) {
    initOwner(parent);

    setParentEffect(parent);

    setOnShown(new EventHandler() {
      @Override
      public void handle(WindowEvent event) {
        recenter();
        onShow();
      }
    });

    if(synchronous) {
      showAndWait();
    }
    else {
      show();
    }
  }

  protected void onShow() {
  }

  @Override
  public void close() {
    removeParentEffect((Stage)getOwner());
    super.close();
  }

Not sure how the classpath. Which is nothing to be ashamed that you started with Eclipse, it is exactly one of those things that an IDE hides on your part.

Read into java classpath and things will be clear. For now, you'll get it to work by running this:

Java - cp. Main

(Note the point - which means "current working directory" as part of a path).

TestStand Java - 1500 error cannot find the class

Hello world

I use Java 1.7 and TestStand 2010.

I try to add a java class in the computer example folder and call the method.

The java class is just as below, because I'm just trying to call my own java class.

I put the class path to start the JAVA virtual machine in the directory where the example of the computer (which is also the directory where I put my java class).

TestStand can call methods of the computer, but not mine (received the error 1500 error cannot find class). I put my my java method call among calls for default computer example.

Also I read similar topics, but again I can not resolve the error.

Where is the part that I'm bored, in fact? Please share some ideas.

Note: I even try to leave the empty class path, but TestStand can always call the methods of the computer. Why?

----------------------

public class TestJava {}

Public Shared Sub main (String [] args) {}

}

public String returnString(boolean a) {}
Return "success";
}

}

To load a class which is within a package, you can use the package rating (or change the example in order to to use). The path to the class is passed directly to the JAVA virtual machine to load the class, but really what is necessary is the package from the class path, including the full path to the class.

This means you need to do the following:

1 set the class path in the base directory where you created all your classes, if you have the following structure:
- MyFile.java
- builds
- - MyPackage
  - - MyFile.class
You must set the classpath in the builds directory

2 when you set up your steps, you must set the path to the class in your steps from Java to MyPackage/MyFile.class (note the separator is a forward slash, not used Windows backslash, then the Browse button is not quite help with that).

Another important thing is that when you set the classpath variable you remove the normal Java class path, if you are using Java classes from the library by default, you may have to add \lib\rt.jar

Problems with video recording

Hello

I have some problems with the video recording on the BlackBerry.

On the BB 9700 my application crashes when I try to stop recording. The file produced
the app is empty.
On BB 9800 I have the same problem unless I have explicitly defined the video resolution, but
in this case, the resolution of the resulting video is different from what I
specify (640 x 480 instead of 320 x 240).
On BB 9300 an application works without problem.

Here's the example I use:

//////////////////////////////////////// App.java

public class App extends UiApplication
{

Public Shared Sub main (String [] args)
{

pushScreen (screen);
}

}

}

}
});
}

}

}

}

public void end()
throws IOException
{
If (this.rc == null) {}
throw new IllegalStateException ("RecordControl not initialized");
}

this.rc.stopRecord ();
This.rc.Commit ();

//
This.VP.Close ();
}

}

Upgrade to an operating system that has the fix is the only solution I'm aware of, but depending on who may or may not be an option.

A screen popup menu is opened after the closure of the dialog box

Hello

I have a test application with a screen containing a button.

When I click on the button (pressing the button on my BlackBerry 9220 trackpad), it opens a dialog box.

Then when I press ESC to my BlackBerry 9220, it closes the dialog box and I'm back on my screen.

Now, if I add to my screen, a menu item, the changes in behavior:

When I click on the button (pressing the button on my BlackBerry 9220 trackpad), it opens a dialog box.

Then when I press ESC to my BlackBerry 9220, it closes the dialog box and opens a menu screen.

So, I would add my item of menu but keeping the old behavior of my application after you close the dialog box.

Any idea?

Thank you.

Best regards.

Here is the code:

Import net.rim.device.api.ui.UiApplication;
Import net.rim.device.api.ui.component.ButtonField;
Import net.rim.device.api.ui.component.Dialog;
Import net.rim.device.api.ui.container.MainScreen;
Import net.rim.device.api.ui.Field;
Import net.rim.device.api.ui.FieldChangeListener;
Import net.rim.device.api.ui.MenuItem;
Import net.rim.device.api.util.StringProvider;
SerializableAttribute public class TestApplication extends UiApplication
{
public TestApplication()
{
this.pushScreen (new TestScreen());
}
Public Shared Sub main (String [] args)
{
Application TestApplication = new TestApplication();
application.enterEventDispatcher ();
}
}
final TestScreen class extends FieldChangeListener implements screen
{
public TestScreen()
{
/ * MyMenuItem MenuItem = new MenuItem (new StringProvider ("my menu item"), 0 x 230000, 0); * /
ButtonField myButtonField = new ButtonField ("button my field");
myButtonField.setChangeListener (this);
This.Add (myButtonField);
/ * this.addMenuItem (myMenuItem); * /
}
' Public Sub fieldChanged (field field, int context)
{
Dialog.Alert ("test");
}
}

Here are a few screenshots:

It comes from the popup menu. create the button with CONSUME_CLICK would be the simplest solution.

Listener Button problem

This is my first attempt at development for the BB storm, and I use JDE 4.7.

I started with a Hello World application, I found and I modified to add a simple button that says RED. When you click on I tried the wallpaper turn RED and change the button to say BLUE, when that is clicked on it turns BLUE changes back to RED button again.

I've implemented this, use a standard listener ButtonField (which I call bhandler in my code). The program type of works, with the odd effect only on the Simulator is that when I click the button, the background color changes but a little menu appears. Anyone else seen this problem of menu? I don't expect to see a menu and I have not coded anything to ask for a menu appear when I click on this button.

Here is my source code. The Manager is in bold. All the answers that I see not why only a menu would be most appreciated... Thank you.

create a new instance of the application
and launch the application on the event thread
HelloWorld APP = new HelloWorld();
theApp.enterEventDispatcher ();
}
public HelloWorld()
{
a new screen
pushScreen (new HelloWorldScreen());
}
}

create a new screen that covers the screen, which provides
standard behavior by default for BlackBerry applications
final HelloWorldScreen class extends screen
{
public HelloWorldScreen()
{

call the constructor of the screen
Super();

Add a title to the screen
LabelField title = new LabelField ("HelloWorld example", LabelField.ELLIPSIS
| LabelField.USE_ALL_WIDTH);
setTitle (title);

Add the text "Hello World!" to the screen
Add (new RichTextField ("Hello World!"));

First define the button handler
                FieldChangeListener bhandler = new FieldChangeListener()
{
' Public Sub fieldChanged (field field, int context)
{
ButtonField buttonField = field (ButtonField);
If (buttonField.getLabel () is 'RED')
{
Bottom newback = BackgroundFactory.createSolidBackground (Color.RED);
getMainManager () .setBackground (newback);
buttonField.setLabel ("BLUE");
}
on the other
{
Bottom newback = BackgroundFactory.createSolidBackground (Color.BLUE);
getMainManager () .setBackground (newback);
buttonField.setLabel ("RED");
}
}
};
Define the button itself use Manager above, this one called RED
ButtonField buttonField = new ButtonField ("RED");     Create a RED button
buttonField.setChangeListener (bhandler);               Implement the handler for button defined above

Add (buttonField); Adds the button to the screen.

}

Override the onClose() method to display a dialog to the user
with "Goodbye!" when the application is closed
public boolean onClose()
{
Dialog.Alert ("Goodbye!");
System.Exit (0);
Returns true;
}
}

Solved in Java development.

Refresh the field label

Hi, I read many posts on the forum but I have not found any that solved my problem.

I'm new to the development of BB and I'm having a problem that I seem not to be able to untangle.

I have a main class and a class of the screen. I have a button that launches a datepicker. When the DatePicker is closed I need the label of the button to refresh with the selected value. How should I do?

I tried with invalidate, creating a CustomButtonField that implements different onFocus, onUnFocus and some other stuff, but I guess I have them implemented in a bad way...

My two classes are these...

public class TestClass extends UiApplication
{

public static calendar alarm1time = Calendar.getInstance (TimeZone.getTimeZone("GMT-3"));

Public Shared Sub main (String [] args)
{

TestClass testClass = new TestClass ();
testClass.enterEventDispatcher ();

}

Public TestClass()
{

pushScreen (new TestClassScreen());

}

}

/ public final class TestClassScreen extends screen
{

public TestClassScreen()
{

ButtonField alarm1 = new ButtonField ("alarm:" + TestClass.alarm1time.get (Calendar.HOUR_OF_DAY) + ":" + TestClass.alarm1time.get (Calendar.MINUTE), ButtonField.FOCUSABLE)

{

public boolean navigationClick (int status, int time)
{

datePicker (1);
Returns true;

}

};

setTitle ("Test alarm");
Add (new RichTextField(""));
Add (alarm1);

}

public void datePicker (mutable int alarmNumber)
{

UiApplication.getUiApplication () .invokeLater (new Runnable()
{

public void run()
{

DateTimePicker datePicker = null;
datePicker = DateTimePicker.createInstance (TestClass.alarm1time, null, "HH: mm");
If (datePicker.doModal ())
{

Calendar cal = datePicker.getDateTime ();
TestClass.alarm1time = cal.

Here I need the label to be updated, in the end the datePicker is Ok

}

}

});

}

}

Thank you

Alex

Welcome to the forums.

Here's one way:

public boolean navigationClick (int status, int time)
{

datePicker(1, this);
Returns true;

}

Public Sub switch of dates (alarmNumber final int, ButtonField buttonToUpdate final)
{

UiApplication.getUiApplication () .invokeLater (new Runnable()
{

public void run()
{

DateTimePicker datePicker = null;
datePicker = DateTimePicker.createInstance (TestClass.alarm1time, null, "HH: mm");
If (datePicker.doModal ())
{

Calendar cal = datePicker.getDateTime ();
TestClass.alarm1time = cal.

buttonToUpdate.setLabel (...)}

}

});

}

A more usual way of being having change listener listen to click on the button and perform a similar treatment in there.

Edit: The Code has been corrected.
