How can I block the keyboard using the glass pane ?

I have a problem with the GlassPaneDemo from the Java Tutorial in
the
uiswing/components/example-swing
folder.
When the glass pane is visible it blocks the mouse input but the
keyboard input doesn't. For example if the glass pane is visible and
you press the F10 key, the menu will be activated. So the keyboard is
not at all blocked.
Can this problem be fixed ? I mean, to really block the keyboard
when the glass pane is visible.
Here I wrote down the specification written in the
Java Documentation at the setGlassPane method from the
RootPaneContainer interface:
The glassPane is always the first child of the rootPane and the
rootPanes layout manager ensures that it's always as big as the
rootPane. By default it's transparent and not visible. It can be
used to temporarily grab all keyboard and mouse input by adding
listeners and the making it visible. by default it's not visible.
As it may be seen, one says that the keyboard input can be blocked.
HOW ?
In hope that I resolve the problem, I have made some changes such as,
adding a key listener to the glass pane add listening to the keyboard events,
but I failed to fix the problem.
Faithfully yours,
Sarmis

Here is an example that I think will work for you.
Note the consume() call on the event object. I think that is what you're after.
import java.awt.event.*;
import java.awt.*;

public class Comparer extends JFrame implements ActionListener
    private GlassComponent myGlassPane;
    private JTextField myField;
    public Comparer()
        getContentPane().setLayout(new FlowLayout());
        getContentPane().add(myField = new JTextField(20));
        setGlassPane(myGlassPane = new GlassComponent());
        JButton theButton = new JButton("Glass");
        theButton.addActionListener(this);
        getContentPane().add(theButton);
        pack();
    public void actionPerformed(ActionEvent anEvent)
        myGlassPane.setVisible(true);
    public static void main(String[] args)
        new Comparer().setVisible(true);
class GlassComponent extends JComponent implements AWTEventListener
    Window myParentWindow;
    public GlassComponent()
        super();
        this.setCursor( Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR) );
        setOpaque(false);
        addMouseListener( new MouseAdapter() {} );
    public void setVisible(boolean aVisibleBoolean)
        if(aVisibleBoolean)
            if(this.myParentWindow == null)
                this.myParentWindow = SwingUtilities.windowForComponent(this);
            Toolkit.getDefaultToolkit().addAWTEventListener(this, AWTEvent.KEY_EVENT_MASK);
        else
            Toolkit.getDefaultToolkit().removeAWTEventListener(this);

        if(anEvent instanceof KeyEvent && anEvent.getSource() instanceof Component)
            if(SwingUtilities.windowForComponent( (Component)anEvent.getSource()) == this.myParentWindow )
                ((KeyEvent)anEvent).consume();

How to use the function pan() of JavaAPI?

public boolean pan(int x, int y) throws java.lang.Exception
Pans to the specified device point.
Parameters:
x - the x of the user's mouse click
y - the y of the user's mouse click
Returns:
true if the pan operation completed successfully
Throws:
java.lang.Exception
I don't know how to use it to move the map, and i can't find any example. Could anyone show me a simple example?
Thanks very much for your help!

The following is extracted from the API doc.
void pan(<int> x, <int> y)
This methods pans the map. The panning offset is specified by screen pixels on vertical and horizontal directions.
Parameters:
x - the panning offset in pixels on horizontal direction. A positive value pans the map to the right and a negative value pans the map to the left.
y - the panning offset in pixels on vertical direction. A positive value pans the map downward and a negative value pans the map upward.
For example, mapview.pan(500, 0) pans the map to the right by 500 pixels.

Redrawing glass pane

Hi, I have a program where I am storing information which takes up some time. I created a progressbar and put it in the glass pane and update it several times during this process. Below i posted a simplified example. In this example it works as it should and the progress bar gets redrawn every time I call pb.update().
However the code I use in the application is complex and the progress bar does not get drawn onto the screen until the method finishes, which is too late. I have tried putting repaint() calls at the end of the update() method, but that does not work. Although the program enters the paint method, nothing gets drawn onto the screen. The only thing that helped was paintimmediately(), which painted the contentPane() on the screen, but did not paint the glassPane.
My question is, how does java determine when to redraw the glass pane, since I don't have a repaint() call anywhere. Is there a way to force java to draw the glasspane on the screen? Or if you have any tips as to what could be the problem.

Read the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/progress.html]How to Use Progress Bars for a working example. You should also read the section from the tutorial on "How to Use Threads" since you are not using the Thread correctly in you simple demo.

Why Glass Pane becomes visible when resizing JInternalFrame?

This qustion has been asked _*here*_ but got no response.
Hello,
I've created a JFrame with JDesktop and one JInternalFrame on it. I've also added a glasspane (which draws a black circle only) to JFrame - it's invisible by default but when I resize JInternalFrame it shows up.. is this correct behavior? Why it is visible only when I resize and diappears when I release mouse button after resize? How I can make it invisible when resizing JInternalFrame? (Is removing JFrame's glasspane only solution?)import java.awt.Graphics;
import javax.swing.JDesktopPane;
import javax.swing.JFrame;
import javax.swing.JInternalFrame;
import javax.swing.JPanel;
public class RunMe extends JFrame {
     public RunMe() {
          this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          this.setBounds(10, 10, 800, 600);
          JDesktopPane desktop = new JDesktopPane();
          JInternalFrame testJIF = new JInternalFrame("test", true, true, true, true);
          testJIF.setBounds(10, 10, 100, 100);
          desktop.add(testJIF);
          testJIF.setVisible(true);
          this.add(desktop);
          this.setGlassPane(new MyGlassPane());
          this.setVisible(true);
     private class MyGlassPane extends JPanel {
          public MyGlassPane() {
               this.setOpaque(false);
          @Override
          protected void paintComponent(Graphics g) {
               g.fillOval(0, 0, 100, 100);
               super.paintComponent(g);
     public static void main(String[] args) {
          new RunMe();
}

First of all, thank you for being upfront about cross posting.
Whether this is "correct" behavior or not may be debatable, but it's certainly expected behavior. From the source of javax.swing.plaf.basic.BasicInternalFrameUI.BorderListener.mousePressed (towards the end of the method)Container c = frame.getTopLevelAncestor();
if (c instanceof RootPaneContainer) {
   Component glassPane = ((RootPaneContainer)c).getGlassPane();
   glassPane.setVisible(true);
   glassPane.setCursor(s);
}The glass pane is made visible to show the resize cursor.
It's set back to visible(false) in finishMouseReleased() which is invoked from mouseRelease and elsewhere (e;g; from cancelResize which is invoked from windowLostFocus)
Looks like you can't use the glass pane for whatever you had planned, the Swing designers have already used it for something else. Or this could be a workaround, depending on exactly what it is you're trying to do.@Override
protected void paintComponent(Graphics g) {
   super.paintComponent(g);
   if (this.isOpaque()) {
      g.fillOval(0, 0, 100, 100);
}You could also declare and use a boolean flag, rather than using isOpaque (which may happen to be set/reset somewhere else in the Swing code ;-)

How to use the CMS functionality in Sun Portal Server 7.2

Hi All,
How to use the CMS functionality using the ccd.war(Portlet) which is available in the library as i could add it to my channel but not able to show the functionality as it is showing the error msg "You are currently not logged in. Please login." should I create userid and there respective roles inorder to use the CMS functionality.
Has any one used this as I could this in glass fish server.
Any Input is appreciated.
Thanks & regards
Srikanth

Have a look at the "*Roles*" section of the portal server 7.2 content management system guide
http://docs.sun.com/source/820-4275/index.html . You can also look at [project mirage|https://mirage.dev.java.net] for some screencasts
Alternatively,
1. ccd.war has 3 portlets in it:
(a) custom content definition portlet
(b) custom content portlet
(c) workflow portlet
2. Inorder to work with these portlets, user needs to be in anyone of the below roles:
(a)Consumer (b) Editor (c) Approver (d) Administrator (e) Submitter (f) Contributor (g) Publisher
3. By default ccd.war gets deployed using a default roles file (/var/opt/SUNWportal/tmp/ccd.roles.properties)
Note: In windows, you may not find this file
4. Access the portlets as a user in any of the role mentioned in the ccd.roles.properties
(OR)
you can use a new roles file which has mapping to your custom roles. For this , undeploy existing ccd.war and deploy again with a new roles.properties file
Hope this helps!

How to use the "identify" feature in new 6.3.1 airport utility?

how to use the "identify" feature in new 6.3.1 airport utility?
so you can find the basestations in larger networks?

There is a workaround, which is to use Airport Utility 5.6.
I can confirm that 5.6 will run on 10.8.4 Mountain Lion, it will recognize the new 2013 Airport Extreme Base Station (A1521) running firmware 7.7.1, and it will give you access to view the device's Log & Statistics, DHCP Clients, and Profiles.
Four caveats:
1) The easiest way to install it is to download the app itself, not an installer or through the App Store. There is a page here where you can download the app: http://coreyjmahler.com/2013/03/08/airport-utility-5-6-on-os-x-v10-8-mountain-li on/ This way, you still have both versions, Airport Utility 6.x.x and 5.6.
2) When you launch 5.6, you'll get a message saying a newer version is available and asking if you want to update. Click Cancel to proceed into the utility.
3) When you click the Manual Setup button in 5.6, you'll get a warning dialog that "This version of AirPort Utility doesn't support this AirPort wireless device and might improperly configure the device if you continue to use it. Check www.apple.com/support/airport for the latest version of AirPort Utility." You can click Continue to get into the utility without issue.
4) You should probably only use 5.6 to view the additional status details. I have not tried to modify and save any AEBS settings using 5.6. There are other discussions here in the forums indicating that attempting to save settings via 5.6 that are no longer available in 6.3.1 will not actually save the settings to the AEBS even if both utilities indicate that the settings are changed. See https://discussions.apple.com/message/22677993#22677993
So, even though you can't use it to modify settings no longer available in Airport Utility 6.3.1, using Airport Utility 5.6 to view DHCP clients, Logs and Statistics is very useful for troubleshooting network issues.
PS - There are two ways to get to the DHCP Clients list, neither of which is obvious The first is to go to the Airport pane -> Summary tab and click on the "Wireless Clients:" label in the Summary display. All of the labels from "Wireless Mode:" down on the Summary display operate as links to view/edit the corresponding info/settings, which is also not obvious at first glance. Also not obvious, clicking on "Wireless Clients:" actually brings up a new pane with three tabs: Logs, Wireless Clients, and DHCP Clients. You can also get to the same pane by going to the Advanced pane and clicking on the Logs and Statistics button.
I hope this is helpful information. Took me a while to find out how to do this.

How to use outside Class in packed library plugins

I have found the very useful article from Michael Lacasse (https://decibel.ni.com/content/docs/DOC-19176) on how to use packed library as plugins. This approach makes the most sense when you try to distribute additional code after your executable has already been installed.
My problem is that when I try to use a class from the main code in a plugin, the plugins won't work anymore. Ideally, I would have liked the parent plugin-interface to inherit from a class used in the main code, or using the class as an input parameter of the plugin would be the next best thing.
I got several errors, some at execution time (#1448) or at edit time ("This VI does not match other VIs in the method: connector pane terminal(s)"). I have settled to use clusters to pass data to the plugins.
My question is: Is it possible to use a class defined in the main code in a packed-project-library, either inherited or as a parameter? If yes, do you have any example?

I should point out that it's important to use the copy THAT'S IN THE PPL, *-NOT-* the copy from your source.
It will compile if you mix them together, but they aren't the same object, and won't share data.
You should never refer to your source code for the class, except to build the PPL.

[Forum FAQ] How to use parameter to control the Expand/Collapse drill-down options in SSRS report?

In SQL Server Reporting Services (SSRS), drill-down is an action we can apply to any report item to hide and show other report items. They all are ways that we can organize and display data to help our users understand our report better. In this article,
we are talking about how to use parameter to control the Expand/Collapse drill-down options in SSRS report.
Consider that the report has a dataset (dsSales) with following fields: SalesTerritoryGroup, SalesTerritoryCountry, CalendarYear, SalesAmount.
1. The report has the following group settings:
Parent Group: SalesTerritoryGroup
Child Group: SalesTerritoryCountry
  Child Group: CalendarYear
   Details: SalesAmount
2. Add three parameters in the report:
GroupExpand:
Available Values: “Specify values”
Label: Yes           Value: Yes
Label: No            Value: No
Default Values: “Specify values”
Value: Yes
CountryExpand:
Available Values: “Specify values”
Label: Yes           Value: =IIF(Parameters!GroupExpand.Value="No",Nothing,"Yes")
Label: No            Value: No
Default Values: “Specify values”
Value: =IIF(Parameters!GroupExpand.Value="No","No","Yes")
YearExpand:
Available Values: “Specify values”
Label: Yes
Value: =IIF(Parameters!GroupExpand.Value="No" or Parameters!CountryExpand.Value="No",Nothing,"Yes")
Label: No            Value: No
Default Values: “Specify values”
Value: =IIF(Parameters!GroupExpand.Value="No" or Parameters!CountryExpand.Value="No","No","Yes")
3. Right click SalesTerritoryCountry icon in the Row Groups dialog box, select Group Properties.
4. Click Visibility in the left pane. Select “Show or hide based on an expression” and type with following expression:
=IIF(Parameters!GroupExpand.Value="Yes", False, True)
Select “Display can be toggled by this report item” option, and select “SalesTerritoryGroup” in the drop down list.
5. Use the same method setting CalendarYear, (Details) drill-down with following expression:
=IIF(Parameters!CountryExpand.Value="Yes", False, True)
=IIF(Parameters!YearExpand.Value="Yes", False, True)
6. Click SalesTerritoryGroup text box in the tablix. Select InitialToggleState property in the Properties dialog box, and type following expression:
=IIF(Parameters!GroupExpand.Value="Yes", True, False)
7. Use the same method setting SalesTerritoryCountry, CalendarYear text box with following expression:
=IIF(Parameters!CountryExpand.Value="Yes", True, False)
=IIF(Parameters!YearExpand.Value="Yes", True, False)
After that, when we preview the report, we can use these three parameters to expand/collapse drill-down.
Note:
In our test, we may meet following issue. We can check the expression of InitialToggleState property to troubleshooting the issue.

How to use search on Flash 8

I am using Flash Pro 8. I created a .fla file which contains
several objects, each of them has the ActionScript. Now I want to
search through all the ActionScript for a variable such as named
GeneratedXML (already used somewhere in the application).
So I go to Edit --> Find and Replace or Find Next. Neither
can locate the "GeneratedXML". But I know there is indeed a
variable named: GeneratedXML, because I can see it right before me.
I just want to test the search function of this tool(Flash
8). I need do a lot of searching and location of a parameters,
function names, etc throughout the .fla file.
Then how to use or do a search for a text in (the
ActionScript) in Flash 8?
Thanks

If you just click the magnifying glass in an actionscript
window its only a simple find and replace for that frame.
Try using the Edit Menu Find and Replace option...

How to Use Column Selector View in Reports

Hi all,
Can someone please advise on how to use the column selector view in CROMD's reporting tool?
Whenever I add a Column Selector view, and check the Enable checkbox of a certain column, a message appears "Click the columns in the selection pane to add more choices". However there is no selection pane, and the only thing I can do within the column is input a column label.
Am I missing any crucial steps here?
Thanks.

Hi,
Choose a column as column selector by enabling the check box and click the columns that has to get into column selector in the left navigation.
On click the columns would get in one by one. After that field that you choose would be displayed in the position of the column in the report table
Typically the purpose is something like this. If you want to dynamically change the first field say by Account Type, Account Region, Account Status and see the revenue then it can be used
