JMenuBar setFont problem.
Hi, I'm trying to change font for my menu bar, but it takes no effect.
Actually, my purpose is to set normal(not bold) font for menu.
Code:
JMenuBar menu=new JMenuBar();
menu.setFont(new Font("Serif", Font.PLAIN, 12));
//Adding menu items to the menubar.
I have tried to change font of menu items but it took no effect either.
Can anybody help me?
Thanks.
Setting the font on the individual menu items should hve worked unless you don't have the specified font installed on your sytem.
However, if you want to change the font globally, use
UIManager.put(MenuItem.font, yourFont);
UIManager.put(Menu.font, yourFont);
This will change the fonts for all menus and menu items to whatever font you specify.

Urgent : JMenuBar repaint problem
hello all,
i'm facing a problem with jmenubar. i have developed an applet which contains a jmenubar, toolbaar & a panel. i'm doing some operation on the panel like rotating it by different angles. these operations are given in the menu. i have given accelerator keys for these menuitems. when i operate with these accelerator keys everything works fine. but when i click on the menuitem then a part of the panel gets panited on the menubar. but when i minimize the window & open it again the extra portion on the menubar disappears. can u suggest me what might be the problem with this. what is happening when we click a menuitem?
any help is appreciated.
Thanks in advancei solved it by changing repaint() into revalidate() & paintImmediately()
i didn't get the reason why this works instead of repaint but now the code is working perfectly.
This was the 1st time i did a cross posting. I had to deliver the solution that day itself that's why i posted it on different forms. i thought some experts will check the forms which they r interested. anyway learned a lesson from this. won't repeat it. -
Vertical JMenuBar width problem
When I flip my JMenuBar vertical instead of horizontal by doing
BoxLayout bl = new BoxLayout(this,BoxLayout.PAGE_AXIS);
setLayout(bl);
in a constructor for a class that extends JMenuBar. When I do that only 3 characters of each JMenu in the menubar are show. The button size is also ruffly half the width of the actual window. I am doing pack() on the JFrame that houses the JMenuBar. At the moment nothing else is in the JFrame. If I do not set the layout of my JMenuBar then I get a regular horizontal one and width is fine. It's only when I want the Menus vertical instead of horizontal. Been experimenting with all kinds of stuff and no go so far. Looking for suggestions?this produces a menubar, with the screen items vertical, but it takes up too much real estate

AffineTransform problem caused by JMenuBar + JTabbedPane
Hello everyone.
I am starting to think that there is a bug in Java, because otherwise what else could cause the problem I am experiencing? Namely: adding a panel with a vertical text (like a Y axis caption) using an AffineTransform (see SSCCE below) causes this text to be misplaced in some cases.
Variant A
Panel is added directly to the application frame. This causes no problems and everything is as it should be.
Variant B
Panel is placed on a tabbed pane and a menu bar is associated with the frame. The vertical text is now shifted away from the place where it should be by the height of the menu bar plus the height of tabs on the tabbed pane. Why is this happening? Am I doing something wrong?
Moreover, when one switches to another tab and then back, the text is now shifted only by the height of the tabs. Once the application window is resized at least a bit, the text jumps right back to the position shifted by tab height plus menu bar height... Strange, strange, strange...

Edited by: -vt- on 23-Apr-2010 13:08You are ignoring the current transform on the Graphics, use the following instead of setTransform():
g2D.rotate(-Math.PI / 2.0, 0, 0); -
The problem is a simple one.
Simply I don't know how to have the two together, every time I try to create a contentPane with the buttons in it I always get errors I would love it if some one could show me how to do this.

Hi, I'm new here so I'm not even sure if I'm posting in the correct forum ^^
I usually don't have problems when building a JFrame and adding items into it but now I'm confused.
When the JFrame is "built", I get a NullPointerException from the Panel's paintComponent method when it's trying to draw an image (g.drawImage())
This is the whole JPanel class
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class PanneauDe extends JPanel
private static final String [] TAB_IMAGE = { "De1.GIF", "De2.GIF", "De3.GIF",
"De4.GIF", "De5.GIF", "De6.GIF" };
private static final int [] TAB_FREQUENCE = {0,0,0,0,0,0};
private static final int SIDE = 100;
private De unDe;
private ImageIcon imageDe;
private boolean aFirstTime;
private int aX, aY;
public PanneauDe()
unDe = new De();
aX = aY = 0;
aFirstTime = true;
addMouseListener(new EcouteurSouris());
public String getStats()
String statsMsg = "";
for ( int iPos = 0; iPos < TAB_FREQUENCE.length; iPos ++ )
statsMsg += "Face " + (iPos + 1) + " : " + TAB_FREQUENCE[iPos] + " fois\n\n";
return statsMsg;
public String getTotal()
int total = 0;
for ( int iPos = 0; iPos < TAB_FREQUENCE.length; iPos ++ )
total += TAB_FREQUENCE[iPos];
return "Le d� a �t� lanc� " + total + " fois";
public void throwDice()
unDe.throwAgain();
TAB_FREQUENCE[unDe.getFace() - 1] ++;
public void paintComponent (Graphics g)
super.paintComponent(g);
g.drawImage (imageDe.getImage(), aX, aY, null); // <---- THIS GENERATES THE NULLPOINTEREXCEPTION
class EcouteurSouris extends MouseAdapter
public void mouseClicked (MouseEvent pMouseEvent)
aX = pMouseEvent.getX();
aY = pMouseEvent.getY();
throwDice();
imageDe = new ImageIcon(TAB_IMAGE[unDe.getFace() - 1]);
repaint();
}When I click in the windows, a picture of a dice (different side, randomly generated by the method throwDice() ), when I click again the first image dissapear and another one appears... and I make statistics about the results.
I tried ...
public void paintComponent (Graphics g)
super.paintComponent(g);
//g.drawImage (imageDe.getImage(), aX, aY, null);
class EcouteurSouris extends MouseAdapter
public void mouseClicked (MouseEvent pMouseEvent)
aX = pMouseEvent.getX();
aY = pMouseEvent.getY();
throwDice();
imageDe = new ImageIcon(TAB_IMAGE[unDe.getFace() - 1]);
Graphics g = getGraphics();
g.drawImage (imageDe.getImage(), aX, aY, null);
g.dispose();
}Everything works correctly, no more NullPointerException, but the images don't dissapear when I click again. They just stay there.
I'm not completly familiar with the repaint/dispose/paintComponent but I really don't understand why i get this NullPointerException error :\
If you see some weird words in the code, it's because i'm canadian-frenchy! :)
Full program is hereThe real question is why are you trying to override the paintComponent() method. Just add the image to a JLabel and add the label to a panel.
However, the problem is that the paintComponent() method is invoked when the frame is shown and since you don't create the image until you do a mouseClick, the image in null. -

hi,
i m new to java still learning new concepts. When i was working with menu and panel i got this problem and i tried a lot but still i havn't got any success. the problem is i m creating a menu with two menuitem - one for "add item" and another for "modify item". What i want to do that on the same frame i want to create two panel of these two item. when i click "add item" option it should show add window and so with modify option. but the problem is if i click add item it shows the addpanel but when i click modify option (add item panel goes- ok ..) but it doesn't show the modify panel, it shows only the main frame on which menu is there.
i cannot understant what is happing here plz guide me.

JCombobox with JMenuBar (as drop down menu)
Hello, i'm trying to make a new component (as generic as possible) to display a tree structure in a combo-like style.
So i finally choose a JTextfield to display the current item + a JMenuBar with Menu and MenuItem generated from a TreeModel (i'm not sure this is the better choice to make, but tha's not my present problem).
2 questions :
1) am I reinventing the wheel ???

Scroll bar problems ..Please help!!!!!!
This is what the program looks like. topPanel has newItemPanel on top of it. when you click continue newItemPanel becomes invisible and newItemDescriptionPanel becomes visible. When you click continue newItemDescriptionPanel becomes invisible and priceEnterPanel becomes visible.
I want newItemDescriptionPanel and priceEnterPanel to have a scroll bar. but everything I have tried hasn't worked. I am new. You will see the code is ugly and there is an attempt to add a scrollbar.
Please help

So you don't know how to get a panel in a scroll pane, and then get that scroll pane into your GUI? Then try doing that by itself, not encumbered with 10000 lines of irrelevant code. Once you have it working, plug it into the big lump of code. Or if you can't get it working, ask about the small problem here. -

In my code, there are two lines:
message.setContent(messageBody, "text/html"); // this sets body of message
message.setContent(bodyPartObject); // this attaches a file
but it turns out that the second "setContent" statement over-writes the first one, so that I get no message in the body of the mail.
What can I do about it, shamik1? Thanks! -
Problem in layout, please help in correcting code
Hello Friends,
I am facing a very strange problem. I have 1 DespktopPane, say DT in which I have created two InternalFrames, say IF1 and IF2. Also there are two JPanels, say P1 and P2. P1 contains various controls and IF1s ContentPane is set to P1 and P2 contains nothing. There two MenuItems, say M1 and M2. On M1s click I displayed IF1 and on M2s click I displayed IF2. Before adding IF2 everything is working fine, i.e. all the controls are able to display on IF1 but after adding IF2 allthe controls are transferred from IF1 to IF2 and now IF1 displays as a blank screen and IF2 contains allthe controls which are added in JPanel p2 whereas IF2s ContenPane is set to P2 and no control is added in P2.
For your reference, here is the code:

}Please provide me the solution so that P1 appears in IF1 and P2 appears in P2.
Thanks in advance,
Ankurall the controls are able to display on IF1 but after adding IF2 allthe controls are transferred from IF1 to IF2 and now IF1 displays as a blank screen
You can't have components at more than one place in the hierarchy. If you add a component to something it is removed from its existing parent if there is one.
I'm not sure how much that helps you - I took one look at your code and ran away screaming. -
Repaint problem while clicking the popup menuitem
Hi all,
iam facing repainting problem in my application. User can initiate a single action from different options such as JButton, double-click of mouse and clicking the menu item form the JPopupMenu.
All these will execute the same code. But when iam using the first two ways, the repainting is properly working and aim getting the required UI and opening the JInternalFrame.
When the last case is being used(ie., clicking the menu item form the JPopupMenu), then the repaint is not working and the window being opened is coming in pieces and then finally i could see the window after some time, which is not the case with the first two cases.
Please help me how to solve and get the window at once. Iam attaching the code.
