मैं JTextArea में स्क्रॉलबार कैसे जोड़ूं?

जैसा कि फ्रेडरिक में उल्लेख किया गया है, इसे प्राप्त करने का आसान तरीका यह है कि वह यह JTextArea के दृश्य क्षेत्र के स्क्रॉलिंग की अनुमति देगा।

बस पूर्णता के लिए, निम्नलिखित है कि यह कैसे प्राप्त किया जा सकता है: 

 < कोड> JTextArea ta = नया JTextArea (); JScrollPane sp = नया JScrollPane (ta); // JTextArea एक JScrollPane में रखा गया है   
 एक बार जब  JTextArea  को  JScrollPane  में शामिल किया गया हो, तो  JScrollPane  को उस स्थान पर जोड़ा जाना चाहिए जहां टेक्स्ट क्षेत्र होना चाहिए। निम्न उदाहरण में, स्क्रॉल सलाखों के साथ पाठ क्षेत्र को  JFrame  में जोड़ा जाता है: 
 
  JFrame f = new JFrame (); । F.getContentPane () (सपा) को जोड़ने;   
  आपको टिप्पणियों में उल्लेख करने के लिए kd304 धन्यवाद कि  JScrollPane  को  JTextArea  के बजाय कंटेनर में जोड़ना चाहिए - - मुझे लगता है कि पाठ्य क्षेत्र को पाठ क्षेत्र के साथ स्क्रॉल फलक के बजाय गंतव्य क्षेत्र में जोड़ने के लिए एक सामान्य त्रुटि है।

    SQL/PHP: Table design question -

    -
    I have two tables, called a "cart" and what I call "items" That the cart be able to store a "item" and a list of quantities. That's why I have created another table "cart_items" which contains the ID of the template, the ID of the item and the quantity. Is this a good design, or should I add another area for the ID of "cart_itim"? Or is there a better way to do it all together? When I try to update my car, I am just running in trouble, my cart items do not update properly, what am I going to do all "cart_times" by car Is connected and then to re-add each "cart_item" and I can not help but it seems that there should be a better way This is a very good design. In the words ER (unit relationship) there are many relationships between objects and cart, through this I mean that an item can appear in many different trains and many different in a cart - Different items may be included In this context ...

    NHibernate Passing Session to the Repository -

    -
    How do I go about passing a session for a repository class? We say that I have two projects 1) TestSite 2) Business Objects The Republican Business Objects Project is included in the project. The NHibernate session has been opened in the test site project. Now, I want to use the same session because the test site initiates the transaction on that session. Currently, I am using the following: var repository = New Customer Resor (_session); Of course, it looks ugly! I'm thinking in some way that a dependency injection frame can be tilted and I can be provided without entering the repository with the ejection object. In our WCF service, we actually use a unitofwork that wraps an operation and stores ISSN for that operation. . The repositories know how they are receiving a hint from the current unit of work under which they are running In case of testing we have a base test class, Those who are included in any test class, who touch the test database, we then control t...

    When I wanted to verify my in-memory xml schema, I found this strange error, did I do anything wrong? [Test] Public Zero Validation XML () {int errorCount = 0; On xmlString = "& lt ;? xml version = '1.0'> ?? response & gt; error code = '1' & gt; success & lt; / error & gt; & lt; / Reaction & gt; "; XmlDocument xmlDocument = New XmlDocument (); XmlDocument.LoadXml (xmlString); XmlDocument.Validate ((sender, e) = & gt; error code +); Assurance First (0, error code); } The exception was: failed: System.InvalidOperationException: XmlSchemaSet on the document is either empty or has a schema in it. Provide schema information before making a valid call System.Xml.XmlDocument.Validate (ValidationEventHandler validationEventHandler) You are trying to validate a schema describing XmlDocument xmlDocument .Schemas.Add (New XmlSchema ()); To verify it in front of an empty schema (as opposed to zero) and verificat...
