c++ - Resize Column Width QTableWidget -

-

मुझे QTableWidget के साथ बनाया गया यह विजेट है: यहां छवि विवरण दर्ज करें

और मैं चाहूंगा कि मेरी मेज का कॉलम विजेट के पूरी चौड़ाई पर कब्जा करने के लिए आकार बदलता है, जबकि पंक्तियों के लिए ठीक है क्योंकि यह है । मुझे पता है कि मेरे जैसे एक समान प्रश्न हैं लेकिन मैं इसे इस तरह हल करने में सक्षम नहीं था .. यह मेरा कोड है 

  शून्य MainWindow :: createTable (int पंक्तियाँ, इंट कॉलम) {mainList = नया QTableWidget; QStringList हेडर लेबल्स; हेडर लेबल्स & lt; & lt; "शीर्षक" & lt; & lt; "निदेशक" & lt; & lt; "वर्ष" & lt; & lt; "काउंटर" & lt; & lt; "रेटिंग"; mainList- & gt; setRowCount (पंक्तियाँ); mainList- & gt; setColumnCount (कॉलम); mainList- & gt; setHorizontalHeaderLabels (headerLabels); मुख्यलिस्ट- & gt; सेट एडिटट्रिगर (QAbstractItemView :: DoubleClicked; QAbstractItemView :: SelectedClicked); mainList- & gt; setSelectionBehavior (QAbstractItemView :: SelectRows); mainList- & gt; resizeColumnsToContents (); मुख्य लिस्ट- & gt; सेटसिज़ पॉलिसी (QSizePolicy :: विस्तार, QSizePolicy :: विस्तार); setCentralWidget (mainList); }    
 
 
 यह ध्यान में रखते हुए कि आप क्यूटी 5 का उपयोग कर रहे हैं,   पूर्व>  QTableWidget * mainList = नया QTableWidget; QHeaderView * header = mainList - & gt; क्षैतिज हेडर (); header- & gt; setSectionResizeMode (QHeaderView :: खिंचाव);   
 OR  
 यदि रीसाइज किया गया है तो QTableView की अंतिम कॉलम उसके माता-पिता को भरने के लिए एक शीर्ष ध्वज है।

I am getting an Ajax call on a jsp page which in turn is redirecting based on the value of a flag variable JSP file. The AJAX call is something like this: $ Ajax ({url: 'uploadwebcamimage.jsp', type: "post", data: {encodeimg: dataUrl, OwnerId: document.Clickpictures.OwnerId.value, OwnerPhone: document.Clickpictures.OwnerPhone.value, mobilepass: document.Clickpictures.
