Hi,

I am getting the following error
"log4j:ERROR setFile(null,true) call failed." When i try to run the application.

The below code is the sample class file which is used for put properties into the the Properties file.

import java.io.File; import java.util.ArrayList; import java.util.List; import java.util.Properties; import org.apache.log4j.Logger; import org.apache.log4j.PropertyConfigurator; /** * This Class will writes the changes(CHANGED, ADDED and DELETED) for the * corresponding elements in to the output file. */ public class LogHooks { // Logger Instance.

String emailLogPath = Util.getKeyValueFromResourceBundle(Constants.KEY_EMAIL_LOG); LogHooks emailLog = new LogHooks(emailLogPath); resultFlag = mailType.sendMail(balFacade, beanInfo, emailLog); emailLog.writeOutputLog();

Hi all,

I have a Swing application. In one of the UI, through a popup menu, we create a rectangle.. Like this we can create n number of rectangles on the UI.. There is an option to rotate the rectangle.

When i try to rotate the rectangle, the application should not allow one rectangle to overlap with other.

For eg. There is a rectangle whose coordinate points are {(1,1), {2,1), {1,2), (2,2)}.. When i rotate this rectangle its new coordinate points will be {(1,2), (2,3), (1,4), (-1,3)}. Suppose there is already a rectangle in this new position, then it should not allow me to move the present rectangle rather than stay at the same position.

As this very urgent... Need your help in this.. I need a sample code, which solves the above problem

Thanks in advance
Smriti

How do i validate? Can u give me some example.

How do i use a NumberFormat

I tried in the following manner
NumberFormat curfmt = NumberFormat.getCurrencyInstance(); curfmt.setMinimumFractionDigits(2); curfmt.setMaximumFractionDigits(2); curfmt.setGroupingUsed(false); txt_amount = new JFormattedTextField(curfmt);

But when i start typing digits into the textfield it is allowing me to enter more than 2 decimal digits.

smriti

No,
The code is written below:
import javax.swing.*; import java.awt.*; import java.awt.event.*; class Testing extends JFrame{ public Testing() { setLocation(400,300); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); String cities[] = {"London","Madrid","New York","Rome","Sydney"}; final JComboBox cbo = new JComboBox(cities); cbo.setBackground(Color.WHITE); cbo.setRenderer(new MyRenderer()); final JCheckBox cbx = new JCheckBox("Enable/Disable",true); cbx.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent ae){ cbo.setEnabled(cbx.isSelected()); }}); JPanel jp = new JPanel(new GridLayout(2,1)); jp.add(cbo); jp.add(cbx); getContentPane().add(jp); pack(); } class MyRenderer extends JLabel implements ListCellRenderer { public Component getListCellRendererComponent(JList list,Object value, int index,boolean isSelected,boolean cellHasFocus) { this.setText((String)value); //this.setOpaque(false);//<----------------- if (!list.isEnabled) { setBackground(Color.white); setForeground(Color.black); } return this; } } public static void main(String args[]){ new Testing().setVisible(true); } }

i created a renderer but even then the background is not set to white in disabled mode.

i entered the foll. code in getListCellRenderer method

if (!list.isEnabled) {
setbackground(Color.WHITE)
}

i tried using formattedTextField..

but if i give the format to be of
JFormattedTextField tamount;
MaskFormatter amount;

try {
amount = new MaskFormatter("################.##");
}
catch(IOException e){}

tamount = new JFormattedTextField(amount);


When i use the above, the application wants me to enter all the 16 numbers. and 2 fraction digits. How do i avoid this?

regards
smriti

Hi,

Is there any other way other than using JFormattedTextField ?

Hi Dave,
I am using swing. I tried your code,

I dont want to limit the numbers to only 2 but i want the user not to enter more than 2 decimals.
For ex. the number can be 4311.22 and not 4311.222222. I want to limit the number of digits in the decimal place to 2.


thanks
smriti
