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।

    After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

    delphi - Mouseover hint for TChart series value -

    -
    I am using a TChart in Delphi 7, and I want to display charts sometime. I am using the following code to set the chain value to a database query: chart1.FreeAllSeries; Chart1.SeriesList.Clear; Chart1.AddSeries (TBarSeries.Create (self)); TBarSeries (chart1.Series [0]) BarStyle :. = BsRectGradient; Stop starting with Query 1; Executed; While EOF does not start chart1.Series [0]. Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End; Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar. Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...? This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you: Process TForm...

    How to Create Master-Details view using Asp.Net MVC framework -

    -
    I am evaluating the Asp.Net MVC framework for my enterprise application for the past few weeks. The one thing I'm trying to achieve is the master-detail view. As it is very clear that there is no vivestate and there is no postback. For example, now I am using the product, customer, order and order details table from the Northwind database and I am using the especial MVC. I want to make master-detail view. Basically I do not have to have separate ideas (pages of other words) for order and order details. View order and order details should be included. How should I design my controller and see how to get this functionality. Thanks & amp; Regards, Burhanuddin Ghee You want to write a domain-specific view-model class Adds an order and details from its order (I'm assuming that order-> order details are 1-> n relation, not familiar with Northwind): public class command view model (Public order order); Set;} public inenemable & lt; Order deletate & gt; ...
