Getting the text from a JTextArea...
hi, I'm making a perfect calculator program and I'm trying to add a Note Pad function to it, I also want to hide that so the other interface can be used; I can get it hided and come again but I'm wondering how could I get the text from the JTextArea INCLUSIVE the enters that are made withing it, so:
theString = jTextArea1.getText();only gives me the text and no enters; suggestions?
I think I displayed it wrongTwo things to keep in mind...
Certain Swing components will just ignore newlines, so you have to be careful where/how you're displaying your multiline text strings. Some components will display it all as one line, some will only display the top line, some will even show \n instead of doing the newline. It all just depends.
And JTextArea does support word wrapping, so just because it looks like there's a newline, there may not be one.

How to get the text present in JTextArea
i am writing application for some system to be computerised and i am not getting how to get the text present in text area and set it into database...can anybody suggest me solution??
You must have named the TextArea like
JTextArea textArea;so, use the getText() method like
String strTextAreaContents = textArea.getText();You can then use JDBC to connect to the database that you want and save your contents that is now in strTextAreaContents.

Getting the text from a text area
I have a application and I wish to take in text typed in from the user into a textArea and then send it into a method however I need to be able to send this information to a static method which accesses a HashTable and then searches for the text inputted by the user word by word. However the getText() wont allow me to access it in a static method and Im not sure of a way around this.
I know I propably haven't explained this very well but any help you can provide is appreciatedOK im going to try and explain a little better.
The main method is currently constructing a HashTable which is then accessed by other methods within the program. Due to this any methods using the HashTable as I understand it must be static. However some of the methods also require input from the user which is entered into a text box in the application. To access this information the method can't be static.
However when i have a method such as this
private static void sendMessage(HashTable theTable, String readMessage)
now as you can see I need to be able to pass it a string and the table.
Problem: How the hell do I do this its driving me nuts. -
Setting a label with the text from cmd
I know that label.setText("sdf"); usually prints out what ever we set in the label. But what i need help in is actually to get the text from the command prompt and print it unto the label. I'm doing a school project that requires users to click a GUI component menu "start server". This actually calls a batch file that connects the pc and a mobile phone with bluetooth. So, actually when the server(pc) is connecting, it prints out text like : "connecting..." . I want to disable the command prompt and actually print all those text unto a label on the GUI. Please help me somebody.
these are three classes that object_au suggested might help me to print things from a cmd to a label:-

How to get the text in a label which is imbeded in a JTextPane
I have created a JTextPane that has 5 JLabels inserted in the text. I have attempted to get the text with the following code snippet.
Component[] lbl = new Componennt[DisplayLetterPane.getComponentCount()];
// JTextPane DisplayLetterPane; is defined previously
lbl = DisplayLetterPane.getComponents();
int componentIndex = 0;
String lblText = new String(((JLabel)lbl[componentIndex]).getText());I have run a dump of the sytledDocument of the JTextPane and I see the JLabel listed as a component.
When this snippet is executed I get the following:
Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException: javax.swing.text.ComponentView$Invalidator
When I check the character where the component for the JLabel is located in the styled document it does not find an instanceof JLabel.
How can I get the text from the labels.
Thank you in advance!JTextPane jtp = new JTextPane();
for (int i = 0; i <5; i++) {
jtp.add(new JLabel("labelText"+i));
Component[] lbl = new Component[jtp.getComponentCount()];
// JTextPane DisplayLetterPane; is defined previously
lbl = jtp.getComponents();
int componentIndex = 0;
for (int i = 0; i < lbl.length; i++) {
System.out.println(((JLabel)lbl).getText());
When I do like the above, it just works fine. Can u share a little bit more of your code? -
Is there a way to get the text written into a text object in an AWTFrame
I am trying to get the text written into the text box in the AWTFrame.
I have tried the following:
<pre> AccessibleTextInfo acinfo;
AccessibleContextInfo actinfo;
AccessibleTextItemsInfo acttinfo;
actinfo = getContextInfoFromContext(ac);
GetAccessibleTextInfo(vmID,ac,&acinfo,actinfo.x,actinfo.y);
printf("char count =%i\n",acinfo.charCount);
printf("OK so far\n");
GetAccessibleTextRange(vmID,ac,0,MAX_STRING_SIZE,sData,MAX_STRING_SIZE);
printf("text =%s\n",sData);</pre>
The charCount is correct but the string returned is always null.
Is this the right way to do this. If not then is there a correct way to get the text from a text box.881530 wrote:

How can I get the "text" field from the actionEvent.getSource() ?
I have some sample code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.ArrayList;
public class JFrameTester{
public static void main( String[] args ) {
JFrame f = new JFrame("JFrame");
f.setSize( 500, 500 );
ArrayList < JButton > buttonsArr = new ArrayList < JButton > ();
buttonsArr.add( new JButton( "first" ) );
buttonsArr.add( new JButton( "second" ) );
buttonsArr.add( new JButton( "third" ) );
MyListener myListener = new MyListener();
( (JButton) buttonsArr.get( 0 ) ).addActionListener( myListener );
( (JButton) buttonsArr.get( 1 ) ).addActionListener( myListener );
( (JButton) buttonsArr.get( 2 ) ).addActionListener( myListener );
JPanel panel = new JPanel();
panel.add( buttonsArr.get( 0 ) );
panel.add( buttonsArr.get( 1 ) );
panel.add( buttonsArr.get( 2 ) );
f.getContentPane().add( BorderLayout.CENTER, panel );
f.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
f.setVisible( true );
public static class MyListener implements ActionListener{
public MyListener() {}
public void actionPerformed( ActionEvent e ) {
System.out.println( "hi!! " + e.getSource() );
// I need to know a title of the button (which was clicked)...
}The output of the code is something like this:
hi! javax.swing.JButton[,140,5,60x25,alignmentX=0.0,alignmentY=0.5,
border=javax.swing.plaf.BorderUIResource$CompoundBorderUIResource@1ebcda2d,
flags=296,maximumSize=,minimumSize=,preferredSize=,defaultIcon=,disabledIcon=,
disabledSelectedIcon=,margin=javax.swing.plaf.InsetsUIResource[top=2,left=14,bottom=2,
right=14],paintBorder=true,paintFocus=true,pressedIcon=,rolloverEnabled=true,
rolloverIcon=,rolloverSelectedIcon=,selectedIcon=,text=first,defaultCapable=true]
I need this: "first" (from this part: "text=first" of the output above).
Does anyone know how can I get the "text" field from the e.getSource() ?System.out.println( "hi!! " + ( (JButton) e.getSource() ).getText() );I think the problem is solved..If your need is to know the text of the button, yes.
In a real-world application, no.
In a RW application, a typical need is merely to know the "logical role" of the button (i.e., the button that validates the form, regardless of whether its text is "OK" or "Save", "Go",...). Text tends to vary much more than the structure of the UI over time.
In this case you can get the source's name (+getName()+), which will be the name that you've set to the button at UI construction time. Or you can compare the source for equality with either button ( +if evt.getSource()==okButton) {...}+ ).
All in all, I think the best solution is: don't use the same ActionListener for more than one action (+i.e.+ don't add the same ActionListener to all your buttons, which leads to a big if-then-else series in your actionPerformed() ).
Eventually, if you're listening to a single button's actions, whose text change over time (e.g. "pause"/"resume" in a VCR bar), I still think it's a bad idea to rely on the text of the button - instead, this text corresponds to a logical state (resp. playing/paused), it is more maintainable to base your logic on the state - which is more resilient to the evolutions of the UI (e.g. if you happen to use 2 toggle buttons instead of one single play/pause button). -
HT1694 The text has disappeared from my emails in my inbox. What can I do to get the text back?
The text has disappeared from my emails in my inbox. What can I do to get the text back?
Try closing the Mail app via the taskbar and see if the email text shows when you re-open the app : from the home screen (i.e. not with the Mail app 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Mail app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
If that doesn't fix it they try a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot. -

Getting the text of a Label from an inputField
Hello everyone,
In my application, I have an inputField and a Label.
The labelFor property of the Label directs to the inputField.
How can I get the text of the label from the inputField ?
Any suggestions ?
Thanks.
Ruthie.Hi Anilkumar,rahul,Valery.
I didn't explain it clear enough.
In my application I use the method reportContextAttributeMessage as follows:
private void checkMandatory(String fieldName, String fieldText){
IWDMessageManager messageMgr = wdControllerAPI.getComponent().getMessageManager();
IWDAttributeInfo attributeInfo = wdContext.getNodeInfo().getAttribute(fieldName);
String value = wdContext.currentContextElement().getAttributeAsText(fieldName);
if (value.length()==0){
messageMgr.reportContextAttributeMessage(wdContext.currentContextElement(),
attributeInfo, IMessageOpenUserApp.MISSING_INPUT,
new Object[] { fieldText },
true);
So,this method executes validity check to an input field
("fieldName").
In the layout I have an inputField and a Label.
The property labelFor of the Label is set to the inputField.
The parameter "fieldText" should be the text of the label.
Is there a way - that when knowing only the context attribute of the inputField - I can get the text of the Label ? what is the meaning of the labelFor property ?
Thanks.
Ruthie. -
I updated my 4S iPhone and now I am getting all the texts from another iPhone on my plan. What do I need to do?
I'm not completely clear on the GSM / LTE network frequencies in US vs Argentina, but I do know that cross-compatibility can be an issue when buying from one country and using in another. Apple products in particular have this problem. What this sounds like to me is that the phone is not compatible with Argentinian networks; or your friend had an AT&T phone and jail-broke it. This is against the end user licensing agreement, and when the phone is next updated is likely to jam the phone.
Sorry but you lost your money.

How do I get old texts from the Cloud
How do I get old text from the Cloud? Issues with my phone forced the Verizon Tech to wipe my phone and start over. He said the Cloud would hold everything and I could retrieve it later. I can't find any of the saved texts that I had. Help please.
Had you previously backed up your texts to the cloud? Yes, you can save things in the cloud, but you must first set it up to do so.

NullPointerException - Cannot get the value from variable f_cashGiven
In SubCheckout.java (a POS), what I want is when Payment button (f_cashPayment) is pressed, the action "Cash" is performed, get the value from Cash Given (f_cashGiven), do the subtraction and post the value as Cash Return (f_cashReturn). The code is filled in actionPerformed. But I cannot get the value by using f_cashGiven.getValue() from VNumber class. It returns NULL. This should be quite straight forward, but I do not know what is wrong. Please help!
