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।

c++ - Cmake produces file extensions in static library archives -

I have recently switched to autotools to cement, since the limiter cross platform is better for development and what I saw When I build a stable library of my C ++ code, all the files inside .cpp.o is a suffix ar income tax PA8 / libgenericTZR.a genericTZR.cpp.o I have seen other libraries made by other tools and they do not do it, I'm not sure this is the realm And there is a bad thing, but how can I create static libraries without cpp file extension? This is my CMake file add_executable (PA8 ISP_Charges.cpp genericTZR.cpp genericTZR.h) set (LIBSRC genericTZR.c genericTZR.h) add_library (genericTZR shared $ {LIBSRC}) add_library (genericTZR shared $$ TARGET_OBJECTS: myObjects & gt;) install add_library (Generic TZR-static static $ {LIBSRC}) set_target_properties (Generic TZR-Static Properties OUTPUT_NAME $ install (TARGETS PA8 DESTINATION BIN) TARGETS GENICTZR GENERICTZR-STATIC DESTINATION lib) Installed (files "$ {PROJECT_BINARY_DIR} /PA8/genericTZR.h...

c# - XML - Serialize class - Some questions -

-
I have the idea of ​​serializing the properties of a class in an XML-file and then uploading this file to the server The reason for this is that I want to download this file again and read the serialized content. Then this kind of structure: file exists (myfile.xml) - & gt; Serialize the file in data from class (myclass.cs) - & gt; Upload file. Now the content may look something like this: Now the problem is, I do not know how to walk. I want the new data to be serialed in the next way, but it should be linked to that XML-file, not a new one. So I download this file and then I serialize the new data as an attachment so that it will look like this: And it should be repeated many times as I want: download file, serial new data and attach it together, then upload it again. Now, the second issue is, I want to read it. I also use XML-class for this. For the type of ultimate type, the data should be serialized, I set the square in which the assets are. But now,...
