Code to restore jPane from minimized down in toolbar?

[Rick Liberato]

.... NO!  both classes do heavy lifting and share data between them. This is a fully operational app and dependent on both main classes.

[Rick Liberato]

mmmmmm .... no!  Both main classes share data/instructions/etc between them. The event listener is listening on the serial com port,on event,parses this data stream,stores it to Derby database and up dates this back out to my jTable. This is a fully functional working app ..... dependent on BOTH main classes to funtion.  

[Paul Clapham]

Well, you're not the first person to write applications and find they need to be changed due to new requirements. It sounds like you already have a communication channel from the serial port via the database to the GUI, so maybe you can piggyback on that to find out whatever it was. Or maybe you can build another communication channel.

[Rick Liberato]

..... Now i'm really lost  :  (

[Rick Liberato]

..... all I need now is the proper code to bring this GUI back up from its iconified state ..... so the end user can again see the Gui.  I don't know how to assemble a working code structure to do this.

[Rick Liberato]

From another class, I'm trying to set this currently inconified Frame back to NORMAL.

i'm doing like this, but not working.  Whats the proper way to call this ?   thanks!  

                 

                   int state=NORMAL;    
                   
                   Frame.setExtendedState(state);

/**
 * A <code>Frame</code> is a top-level window with a title and a border.
 * <p>
 * The size of the frame includes any area designated for the
 * border.  The dimensions of the border area may be obtained
 * using the <code>getInsets</code> method, however, since
 * these dimensions are platform-dependent, a valid insets
 * value cannot be obtained until the frame is made displayable
 * by either calling <code>pack</code> or <code>show</code>.
 * Since the border area is included in the overall size of the
 * frame, the border effectively obscures a portion of the frame,
 * constraining the area available for rendering and/or displaying
 * subcomponents to the rectangle which has an upper-left corner
 * location of <code>(insets.left, insets.top)</code>, and has a size of
 * <code>width - (insets.left + insets.right)</code> by
 * <code>height - (insets.top + insets.bottom)</code>.
 * <p>
 * The default layout for a frame is <code>BorderLayout</code>.
 * <p>
 * A frame may have its native decorations (i.e. <code>Frame</code>
 * and <code>Titlebar</code>) turned off
 * with <code>setUndecorated</code>. This can only be done while the frame
 * is not {@link Component#isDisplayable() displayable}.
 * <p>
 * In a multi-screen environment, you can create a <code>Frame</code>
 * on a different screen device by constructing the <code>Frame</code>
 * with {@link #Frame(GraphicsConfiguration)} or
 * {@link #Frame(String title, GraphicsConfiguration)}.  The
 * <code>GraphicsConfiguration</code> object is one of the
 * <code>GraphicsConfiguration</code> objects of the target screen
 * device.
 * <p>
 * In a virtual device multi-screen environment in which the desktop
 * area could span multiple physical screen devices, the bounds of all
 * configurations are relative to the virtual-coordinate system.  The
 * origin of the virtual-coordinate system is at the upper left-hand
 * corner of the primary physical screen.  Depending on the location
 * of the primary screen in the virtual device, negative coordinates
 * are possible, as shown in the following figure.
 * <p>
 * <img src="doc-files/MultiScreen.gif"
 * alt="Diagram of virtual device encompassing three physical screens and one primary physical screen. The primary physical screen
 * shows (0,0) coords while a different physical screen shows (-80,-100) coords."
 * style="float:center; margin: 7px 10px;">
 * <p>
 * In such an environment, when calling <code>setLocation</code>,
 * you must pass a virtual coordinate to this method.  Similarly,
 * calling <code>getLocationOnScreen</code> on a <code>Frame</code>
 * returns virtual device coordinates.  Call the <code>getBounds</code>
 * method of a <code>GraphicsConfiguration</code> to find its origin in
 * the virtual coordinate system.
 * <p>
 * The following code sets the
 * location of the <code>Frame</code> at (10, 10) relative
 * to the origin of the physical screen of the corresponding
 * <code>GraphicsConfiguration</code>.  If the bounds of the
 * <code>GraphicsConfiguration</code> is not taken into account, the
 * <code>Frame</code> location would be set at (10, 10) relative to the
 * virtual-coordinate system and would appear on the primary physical
 * screen, which might be different from the physical screen of the
 * specified <code>GraphicsConfiguration</code>.
 *
 * <pre>
 *      Frame f = new Frame(GraphicsConfiguration gc);
 *      Rectangle bounds = gc.getBounds();
 *      f.setLocation(10 + bounds.x, 10 + bounds.y);
 * </pre>
 *
 * <p>
 * Frames are capable of generating the following types of
 * <code>WindowEvent</code>s:
 * <ul>
 * <li><code>WINDOW_OPENED</code>
 * <li><code>WINDOW_CLOSING</code>:
 *     <br>If the program doesn't
 *     explicitly hide or dispose the window while processing
 *     this event, the window close operation is canceled.
 * <li><code>WINDOW_CLOSED</code>
 * <li><code>WINDOW_ICONIFIED</code>
 * <li><code>WINDOW_DEICONIFIED</code>
 * <li><code>WINDOW_ACTIVATED</code>
 * <li><code>WINDOW_DEACTIVATED</code>
 * <li><code>WINDOW_GAINED_FOCUS</code>
 * <li><code>WINDOW_LOST_FOCUS</code>
 * <li><code>WINDOW_STATE_CHANGED</code>
 * </ul>

Call

myReferenceToAFrame.setState( Frame.NORMAL );

or if you are calling it within a class that extends Frame

setState( Frame.NORMAL );

Why on earth did you post the entire java.awt.Fame file? Calling setState() happens in your code, not inside the Frame code.

[Rick Liberato]

.... both give me errors "non-static method setState(int) can not be referenced from a static context"

Carey Brown wrote:Call

What you CAN'T do is call

Frame.setState()

This is the syntax for calling setState() IF setState() was a static method, which it is not.
You have to replace "Frame" with your own Frame reference variable.
If it still doesn't work post the 1-3 lines that are giving you grief.

[Rick Liberato]

The calling class does not extend Frame,  so here is how I'm calling setState:

         String bb = "911";                      
    
              if (e911.equals(bb))
                {
                    
                   MainDisplay.setState(Frame.NORMAL);   // <<<  this give me the same "static/non-static error
                    
                        
                    jLabel1.setVisible(true);
                    jLabel4.setVisible(true);
                    jLabel3.setVisible(true);
                    jLabel5.setVisible(true);

[Rick Liberato]

my guess is that the "MainDisplay" GUI class that was generated by the Netbeans IDE has the "setState();" un-accessible to my outside class

[Rick Liberato]

..... "setExtendedState" .......same error

[Rick Liberato]

...... if I put "setExtendedState(Frame.NORMAL);" under a test jButton in the MainDisplay class and manually maximized the screen, pressing this test button brings the Frame back to NORMAL just fine.  I just can't get " setExtendedState(Frame.NORMAL);" to work outside of my GUI class (MainDisplay).

[Carey Brown]

Somewhere in your code you are creating a new instance of MainDisplay like this

new MainDisplay();

Or

MainDisplay mainDisplay = MainDisplay();

The second one gives you a reference variable called "mainDisplay" (or whatever). Use this to invoke setState(), as in

mainDisplay.setState( Frame.NORMAL );

I notice you keep referring to setExtendedState(), how is that different than setState(). I know setState() works but I don't know anything about setExtendedState().

[Rick Liberato]

SetState();  .... is old version  gives you only "NORMAL" and "ICONIFIED"

setExtendedState(); ..... is newer version adds "MAXIMIZED_HORIZ" and "MAXIMIZED_VERT" and "MAXIMIZED_BOTH" as well.

[Rick Liberato]

.......   No error now! ..... but still NOT taking my manually iconified frame back up to normal  :  (

   String bb = "911";                      
    
              if (e911.equals(bb))
                {
                     
                    
                    MainDisplay mainDisplay = MainDisplay();
                    mainDisplay.setExtendedState(JFrame.NORMAL);    
                    

                    jLabel1.setVisible(true);
                    jLabel4.setVisible(true);
                    jLabel3.setVisible(true);
                    jLabel5.setVisible(true);

[Rick Liberato]

not working with ....JFrame.NORMAL or Frame.NORMAL or jFrame.NORMAL

[Rick Liberato]

sorry .... JFrame, jFrame and Frame

[Carey Brown]

I'm not sure anymore how to convey this to you. You ALREADY have a MainDisplay reference. Don't create yet another MainDisplay because it won't have any effect on your original instance.

Not counting these incorrect lines

MainDisplay mainDisplay = MainDisplay();
 mainDisplay.setExtendedState(JFrame.NORMAL);

show me the code where you are calling

new MainDisplay();

Come to think of it, I don't see how this compiled

MainDisplay mainDisplay = MainDisplay();

If MainDisplay is a class then you would have needed

MainDisplay mainDisplay = new MainDisplay();

[Rick Liberato]

Netbeans GUI builder must have something to do with this in that I am not calling this up properly  :  (

What is the context of this snippit? Is it inside a method that is inside your MainDisplay class? Let's see the whole MainDisplay class, or at least the whole method.

[Rick Liberato]

..... I tried that a few hrs back ..... didn't work  :  (

                            MainDisplay mainDisplay = new MainDisplay(); // <<<< Did not work with "new"!   no error ....but not working!
                            mainDisplay.setState(Frame.NORMAL);

[Rick Liberato]

"What is the context of this snippit? Is it inside a method that is inside your MainDisplay class? Let's see the whole MainDisplay class, or at least the whole method."

The two main class in this app are "MainDisplay" and "TwoWaySerialComm"   Both have a "main class"  ..... to run this app, you run "MainDisplay" .... that calls "TwoWaySerialComm" to run as well. Both are fully posted on here.

[Rick Liberato]

This is a working app!  https://www.screencast.com/t/6Rk2qkcEEKJ5

I have a listener already on the serial com port waiting for a string of data.

on event,  I parse and save to derby database then query that data back to my GUI. I also turn on labels on the GUI and post that a 911 call was made and from what phone extension it came from.

The only problem I have is that if this apps window is iconified down in the tool bar at that time (911 call detected) , I can't see the warning message it is showing.  I am simply looking for the code that will deiconify my apps window!  so, I already have a list of things that are carried out "on event"  .... just need to add a way to "show my hidden apps gui"

[Carey Brown]

Here is my attempt at a small runnable piece  of code that demonstrates your issue. That being: how to deiconify from another class instance, e.g. External.

import java.awt.EventQueue;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;


public class MainDisplay extends JFrame
{
	public static void main( String[] args )
	{
		//...
		
        EventQueue.invokeLater(() -> {
            new MainDisplay().setVisible(true);
        });
	}

	public MainDisplay()
	{
		initComponents();
		External ext = new External( this );
	}
	
	public void initComponents()
	{
		setTitle( "MainDisplay" );
		iconifyButton = new JButton( "ICONIFY" );
		setLayout( new FlowLayout() );
		add( iconifyButton );
		iconifyButton.addActionListener(new ActionListener() {
			@Override
			public void actionPerformed( ActionEvent evt )
			{
            	iconify();
			}
        });
		setSize( 300, 300 );
	}
	
	public MainDisplay getMainDisplay()
	{
		return this;
	}
	
	public void iconify()
	{
		EventQueue.invokeLater(() -> setExtendedState( JFrame.ICONIFIED ) );
	}
	
        // you could also call this method from somewhere inside the MainDisplay class
	public void deiconify()
	{
		EventQueue.invokeLater(() -> setExtendedState( JFrame.NORMAL ) );
	}
	
	// !!!! NOT STATIC !!!!
	JButton iconifyButton;
}

class External
{
	MainDisplay		mainDisplay;
	public External( MainDisplay mainDisplay )
	{
		this.mainDisplay = mainDisplay;
	}
	
	// Need some event in your External instance to
	// call this
	public void deiconify()
	{
		mainDisplay.iconify();
	}
}

[Rick Liberato]

Thanks!   ..... I've run sample code like this before with no problem.  Here the code is making "its own" Frame and acting on it.

The problem I'm having is that the way Netbeans builder creates my GUI, I cant see what code is needed to take the iconified window back to a visible display.

Can you show me a simple example of a Netbeans builder created GUI Frame with an external class calling the GUI back up from the toolbar? (lets say a simple timer firing (external class) a command to de-iconify the GUI)in the GUI's "MainDisplay" class

[Carey Brown]

Can you provide a SSCCE to illustrate where you are stuck?

I've tried to illustrate by example how to create an SSCCE but no luck. Read the above link.

[Rick Liberato]

.... making great progress!! :  )   I have at least 30 code snips that don't work  :  (

These are the only ones that allow me to compile:

            setExtendedState(Frame.NORMAL);      
            setExtendedState(JFrame.NORMAL);    
            setExtendedState(NORMAL);  

Works "in" the GUI builder Frame class  .... but not in my external class where I need it!  :  (

[Rick Liberato]

.... this may be what I need  , but error says "state is "private"  .... I will need to make that "public" and/or "static"  I would think.  (found in the JDK1.8)   I don't know how to change this in Netbeans GUI builder.  Is it possible to make this change in the Java JDK files itself?

Frame frame = getFrame();
        if (frame != null) {
            frame.setExtendedState(state | Frame.ICONIFIED);



Frame frame = getFrame();
        if (frame != null) {
            frame.setExtendedState(state | Frame.&~ICONIFIED);

[Rick Liberato]

.... after 3 days of trying to do this and getting nowhere, I gave up for now.  I just now added a listener to the "911"label on the GUI that gets turned on in this event, then on label event, I call "setExtendedState(NORMAL);"
works perfect!!  .... all of 3 mins to do  :  (
