Is it possible to add a JPanel to a JMenuItem? - HELP!!!!!!!!!!!!!!!!!!!!!!
Is it possible to add a JPanel to a JMenuItem? If so how would you do this. What I'm trying to do is add a JPanel that has a bunch of JButtons added to the panel and then add the JPanel to the JMenuItem. This allows you to have more items added to one item on a JMenuItem. But what happens is that the JPanel does not show when I add it to a JMenuItem? Does any know why? Please help if you can?
thanks,
newbie
A JMenuItem extends from an awt.AbstractButton
A Jpanel extends from a JComponent
Due to its higher position in the component tree a JPanel cant be added to an JMenuItem

Is it possible to add a JPanel to JScrollPane
i created a JPanel .
I gave the layout for this panel to be NULL .
Then i added 16 JLabels in that JPanel(using setbounds)
when i try to add it to the container i was not able to see last two labels
So i tried to create a JscrollPane and i add that JPanel to this JScrollPane
I cant see any difference and the JScrollPane was not working
The code is:
JScrollPane scrollPane = new JScrollPane(p);
getContentPane().setLayout(new BorderLayout());
getContentPane().add(scrollPane,BorderLayout.CENTER);
I dont know
1) Is it correct to add a JPanel to JScrollPane
2)Is it compulsory to use a Layout style while using JScrollPanei created a JPanel .

Have you checked that the size of this container is coherent
with the one of your JPanel ?
And even before, can this container let the JPanel take the size needed for the
16 JLabels ?

However the component/container you whish to view with the JScrollPane
can have the Layout you whish. -
Is it possible to add extra frames to the collage templates?
At the moment in using PSE10 Trail, and the maximum amount of frames i can see that i can use is 19, is it possible to add more???
Any help much appreciated
GeorgieYou can use all of the frames in the content panel. After arranging your collage and clicking done, you need to save the file as a PSD file to preserve all the layers that were automatically created.
Then open Full Edit and click:
File >> Open
Then navigate to your PSD file.
If you open the layers pallet you will see that each photo in your collage has it’s own individual layer.
Select one of the layers (highlight it) then choose a from the content tab and click apply.

Is it possible to add an Actionlistener to a JPanel?
Hi
Is it possible to add a listener to a panel that would react when the mouse button was pressed whilst over the panel.
I have panels displying data and when the user clicks on th panel I wish to expand the data for better viewing.
MickpDo I add the mouselistener to the panel itself or do I add it to the Frame and have to determine that the mouse is over the panel?

displayButtons();
getContentPane().add(panel);
setVisible(true);
public void displayForm() throws SQLException{

setSize(600,740);
// Center the frame
Dimension dim = getToolkit().getScreenSize();
setLocation(dim.width/2-getWidth()/2, dim.height/2-getHeight()/2);

Border etched = BorderFactory.createEtchedBorder();
panel = new JPanel();
panel.setLayout( null );
//panel.setBackground(new Color(1,90,50));

I am still having trouble here. would it be posible to add a scrollpanel to this form? Can anyone provide me with a working piece of code so I see how it actually works.

Is it possible to add a JToolBar to JSplitPane?
When I try to add Jtoolbar to JSplitPane, it gives me the following exception:
Exception in Thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: cannot add to layout: unknown constraint: null
Is it not possible to add a JToolBar to a JSplitPane? Is it because I have not defined what is supposed to happen when the user clicks "next" or "previous" yet? What I ultimately want to happen is for something to move up in all the components of the split pane (it's a nested pane) when I hit "next," and to move back when i hit "prev" (buttons in the jtoolbar)I believe that you don't want to add the JToolBar to the JSplitPane, but instead you want to add the JToolBar to the Panel that holds the JSplitPane. For eg:
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Dimension;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JSplitPane;
import javax.swing.JToolBar;
class FuSwing1
private JPanel mainPanel = new JPanel();
private JSplitPane splitpane;
public FuSwing1()
JToolBar toolbar = new JToolBar();
toolbar.add(new JButton("foo 1"));
JPanel redPanel = new JPanel();
JPanel bluePanel = new JPanel();
redPanel.setBackground(Color.red);
bluePanel.setBackground(Color.blue);
splitpane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, redPanel, bluePanel);
mainPanel.setPreferredSize(new Dimension(400, 400));
mainPanel.setLayout(new BorderLayout());
mainPanel.add(toolbar, BorderLayout.NORTH);
mainPanel.add(splitpane, BorderLayout.CENTER);
public JPanel getMainPanel()
return mainPanel;
public void setDividerLocation(double loc)
splitpane.setDividerLocation(loc);
private static void createAndShowUI()
FuSwing1 fu1 = new FuSwing1();
JFrame frame = new JFrame("FuSwing1");
frame.getContentPane().add(fu1.getMainPanel());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
fu1.setDividerLocation(0.6);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
public static void main(String[] args)
java.awt.EventQueue.invokeLater(new Runnable()
public void run()
createAndShowUI();

Is it possible to minimize a JPanel
I have a program that extends JPanel. I'd like to add a standard minimize button to the upper right-hand corner of this panel like on a JFrame. I'd also like there to been an item in the taskbar (I'm running on NT) for this application when this app gets launched because sometime the JPanel gets lost behind other windows and you really don't know that it's there. I'm very new to Swing so I'm not even sure if it's possible to minimize a JPanel.
Thank,
JohnYou can only minimize a high-level window in AWT and Swing. You can add your panel to a frame class and that will allow you to minimize the whole thing.
As an alternative, I have code that you can use to ensure your application stays on top of all other windows. It is a freeware (GNU license) release called WInterface and it allows programmatic maximizing, minimizing and making windows 'always on top'. E-mail me for a copy.

Hello Frnds,
my problem is quite weird!! i will try to explain..as much as I can !!
My requirement is I want to show same JPanel in JDialog and JFrame at once..!!
I am adding a
JPanel A ---> JDialog
JPanel A ---> JScrollPanel B
JScrollPane B ---> JFrame.. and making frame and dialog visible together.. but JPanel is visible in dialog only..
if i dont add in JDialog.. then JPanel is visible in frame.. !!.. but why that??
JFrame fr = new JFrame();
JPanel np = new JPanel(); // This JPanel is added Twice
np.setBounds(0, 0, 128, 128);
JScrollPane scroll=new JScrollPane(np); // Once JPanel added here..
scroll.setPreferredSize(new Dimension(385,385));
fr.add(scroll);
JDialog dlg=new JDialog(fr, "Another Panel", false);
dlg.add(np); // Second Time JPanel added here..
dlg.pack();
dlg.setVisible(true);
fr.setVisible(true);Let's make it very clear : it is NOT possible to add
the same instance of a component to two different
containers.
Is it possible to have frame with component.. but on closing that frame component shifts to another frame.. and vice versa I will add to the above:
it is NOT possible to add the same instance of a component to two different containers... at the same time. Does that clarify it?
Why is it so hard to try it yourself?
Instead of waiting a couple of hours hoping someone answers the question you could have solved your problem in a couple of minutes. -
Is it possible to add markups to a PDF that I am not the author of
Most of the PDFs I generate are from other applications (like Autocad) where I "print to PDF" to create the file. Most of the PDFs I recevie are generated the same way. Prior to Acrobat Reader 8, it was simple for me and my collueges to exchange information on these PDFs by using markup tools and resending them with markups. Since Acrobat 8 has come along, I now find it impossible to markup a drawing (no matter if I have created it using Print to PDF or if someone has sent it to me). I went to the knowledge base and see that the drawing has to be enabled for markup in one of 2 ways
In an open PDF, choose Comments > Enable For Commenting In Adobe Reader, and then save the PDF.
Start the wizard to initiate a shared review or an email-based review and follow the on-screen instructions. When you’re finished, commenting is enabled in the PDF that you specify for the review.
Well, there is no Comments selection in my toolbar. Second method is given by
Quickstart: Start an email review
An email-based review lets you track review status and merge received comments into the PDF.
Click Review & Comment and choose Attach For Email Review.
If prompted, enter your identity information to create a reviewer profile.
Follow the on-screen instructions to select the PDF, invite reviewers, and send the email invitation.
If your email application doesn’t send email automatically, you may need to answer alert messages and switch to your email application to finish sending the message
But there is no Review & Comment button to click.
So, can someone tell me, can I still do a simple markup of any PDF? Even if I have to jump through hoops can I? I guess I can understand Why Adobe has done away with this feature in their free tool, as they were not getting any revenue off of it, but it greatly diminishes the usefulness of Acrobat Reader and therefore all PDFs for me.
Thanks in advance for your response.To enable this right you need Acrobat, not the free Reader.
However, starting from Reader X it is possible to add simple markups to any file, unless it has been specifically disallowed by the creator of the file. -
In contacts there is the possibility to add a new event, as the birthdays, but they do not appear in iCal. Is there any way to make that possible? It is normal to have a person with his birthday, anniversary and others key dates you want to link to such person, but the only one shows up is the birthday. How to be able to show all those dates linked to people in the agenda in the iCal?
ThanksHi,
I sugggest you try my application, Dates to iCal. It is shareware with a 2 week trial period.
Dates to iCal 2 is a replacement for Apple's birthday calendar for iCal. It has a range of features to allow the user to choose what, and what not, to sync to iCal from Address Book.
As well as automatically syncing birthday dates from Address Book, Dates to iCal 2 can sync anniversary and custom dates. It can set up to five alarms for each date in iCal and can also set different alarms for birthdays and anniversaries. It allows the option of only syncing from one Address Book group. This application also allows for the titles of the events sent to iCal to be modified to the user's preference.
Best wishes

Is it possible to add a graphics card to the back of my HP
Hello I want to know if it's possible to add a new graphics card to the back of a Laptop not inside of it but on the back of my laptop ??? my graphics Card is a Intel 4000 graphics card is a terrible for gaming TERRIBLE !!!
Not sure where it would go on the back, but no the system is closed. There is no place to insert a graphics card or attach it. You will find some hokey stuff on the internet where people say you can plug a video card in the wireless card slot but those are a hoax at worst and at best they do not tell you that such a thing would not even perform as well as what you have and is likely to damage the motherboard.

Is it possible to add a hdmi port? Hp envy 23-d010ea all-in-one
I wanted to get a Ps4 soon but i dont have a tv, and on my computer i dont have a hdmi port. i see on other models of my computer they have it for example on the 23-d052 its like this
Where as on my one is like this
so that part is just an empty space. i was wondering if it were possible to add the hdmi port or if there was a way i could still play the ps4 on my computer?
This question was solved.
View Solution.The USB 3.0 to HDMI adapter referenced above, is only designed to connect to a USB port on you computer and output an HDMI signal to an HDTV or monitor. It will not allow you to connect the HDMI output of a game console to your computer.
It may be possible to purchase all the components necessary to add that functionality to your computer, however the cost would far exceed the price of a new monitor or HDTV. Please purchase an inexpensive HDTV or monitor to use with your PlayStation.
If you have any further questions, please don't hesitate to ask.

When creating a custom SearchPlugin, is it possible to add more code such as uppercase conversion of the searchTerms and IF statements that change the URL depending on the searchTerms? Every time I try to add something firefox doesn't want to add it as a search plugin. I need to create a more powerful search tool for personal use.
I've found some external software applications that will do it, so that leads me to believe its not possible within ID CC.
