java - How to make the row editable(false) in JTable -


संभव डुप्लिकेट:

मैं नेटबीन्स का उपयोग कर एक आवेदन विकसित कर रहा हूं।

मैंने एक जेटीबल प्रारूप में एक रिपोर्ट तैयार की है।

यह ठीक से काम करता है लेकिन पंक्तियों और कॉलम संपादन योग्य हैं, और मैं उन्हें गैर-संपादन योग्य।

अपने टेबल मॉडल में आप isCellEditable () विधि: 

  सार्वजनिक वर्ग MyModel डिफ़ॉल्टTableModel {सार्वजनिक MyModel (वस्तु [] [] डेटा, ऑब्जेक्ट [] cols) {super (data, cols); } सार्वजनिक बूलियन है CellEditable (int row, int col) {return false; }}

It usually works, but when there is an exception method that is decorated with MyHandleError (see = "special error...

Problem 2: When I gather the first part off the part, it is unable to run the full MPEG file is. Duration of each piece: 1 second Example: wheel = ["yui_2", "yui_3", "yui_4", "yui_5", "yui_6"...
