model里面的data，角色判断为 case Qt::TextAlignmentRole: { return QVariant(Qt::AlignCenter |); }

小白不懂啊。能不能详细说说？

原文为《Qt中将QTableView中的数据导出为Excel文件>>，地址http://blog.csdn.net/superjoel/article/details/5321404，资源比较难下载，我下载好帮作者上传下。实例可用，简单易懂，对于QTableView导出为excel新手比较合适！谢谢原作者！

常用代码整理： 12.判断邮箱格式是否正确的代码： //利用正则表达式验证 -(BOOL)isValidateEmail:(NSString *)email { NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}"; NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES%@",emailRegex]; return [emailTest evaluateWithObject:email]; } 13.图片压缩用法：UIImage *yourImage= [self imageWithImageSimple:image scaledToSize:CGSizeMake(210.0, 210.0)]; //压缩图片 - (UIImage*)imageWithImageSimple:(UIImage*)image scaledToSize:(CGSize)newSize { // Create a graphics image context UIGraphicsBeginImageContext(newSize); // Tell the old image to draw in this newcontext, with the desired // new size [image drawInRect:CGRectMake(0,0,newSize.width,newSize.height)]; // Get the new image from the context UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext(); // End the context UIGraphicsEndImageContext(); // Return the new image. return newImage; } 14.亲测可用的图片上传代码 - (IBAction)uploadButton:(id)sender { UIImage *image = [UIImage imageNamed:@"1.jpg"]; //图片名 NSData *imageData = UIImageJPEGRepresentation(image,0.5);//压缩比例 NSLog(@"字节数:%i",[imageData length]); // post url NSString *urlString = @"http://192.168.1.113:8090/text/UploadServlet"; //服务器地址 // setting up the request object now NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ; [request setURL:[NSURL URLWithString:urlString]]; [request setHTTPMethod:@"POST"]; // NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"]; NSString *contentType = [NSString stringWithFormat:@"multipart/form-data;boundary=%@",boundary]; [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; // NSMutableData *body = [NSMutableData data]; [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithString:@"Content-Disposition:form-data; name=\"userfile\"; filename=\"2.png\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; //上传上去的图片名字 [body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[NSData dataWithData:imageData]]; [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [request setHTTPBody:body]; // NSLog(@"1-body:%@",body); NSLog(@"2-request:%@",request); NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; NSLog(@"3-测试输出：%@",returnString); 15.给imageView加载图片 UIImage *myImage = [UIImage imageNamed:@"1.jpg"]; [imageView setImage:myImage]; [self.view addSubview:imageView]; 16.对图库的操作选择相册： UIImagePickerControllerSourceTypesourceType=UIImagePickerControllerSourceTypeCamera; if (![UIImagePickerControllerisSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) { sourceType=UIImagePickerControllerSourceTypePhotoLibrary; } UIImagePickerController * picker = [[UIImagePickerControlleralloc]init]; picker.delegate = self; picker.allowsEditing=YES; picker.sourceType=sourceType; [self presentModalViewController:picker animated:YES]; 选择完毕： -(void)imagePickerController:(UIImagePickerController*)pickerdidFinishPickingMediaWithInfo:(NSDictionary *)info { [picker dismissModalViewControllerAnimated:YES]; UIImage * image=[info objectForKey:UIImagePickerControllerEditedImage]; [self performSelector:@selector(selectPic:) withObject:imageafterDelay:0.1]; } -(void)selectPic:(UIImage*)image { NSLog(@"image%@",image); imageView = [[UIImageView alloc] initWithImage:image]; imageView.frame = CGRectMake(0, 0, image.size.width, image.size.height); [self.viewaddSubview:imageView]; [self performSelectorInBackground:@selector(detect:) withObject:nil]; } detect为自己定义的方法，编辑选取照片后要实现的效果取消选择： -(void)imagePickerControllerDIdCancel:(UIImagePickerController*)picker { [picker dismissModalViewControllerAnimated:YES]; } 17.跳到下个View nextWebView = [[WEBViewController alloc] initWithNibName:@"WEBViewController" bundle:nil]; [self presentModalViewController:nextWebView animated:YES]; //创建一个UIBarButtonItem右边按钮 UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:@"右边" style:UIBarButtonItemStyleDone target:self action:@selector(clickRightButton)]; [self.navigationItem setRightBarButtonItem:rightButton]; 设置navigationBar隐藏 self.navigationController.navigationBarHidden = YES;// iOS开发之UIlabel多行文字自动换行（自动折行） UIView *footerView = [[UIView alloc]initWithFrame:CGRectMake(10, 100, 300, 180)]; UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(10, 100, 300, 150)]; label.text = @"Hello world! Hello world!Hello world! Hello world! Hello world! Hello world! Hello world! Hello world!Hello world! Hello world! Hello world! Hello world! Hello world! Helloworld!"; //背景颜色为红色 label.backgroundColor = [UIColor redColor]; //设置字体颜色为白色 label.textColor = [UIColor whiteColor]; //文字居中显示 label.textAlignment = UITextAlignmentCenter; //自动折行设置 label.lineBreakMode = UILineBreakModeWordWrap; label.numberOfLines = 0; 30.代码生成button CGRect frame = CGRectMake(0, 400, 72.0, 37.0); UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; button.frame = frame; [button setTitle:@"新添加的按钮" forState: UIControlStateNormal]; button.backgroundColor = [UIColor clearColor]; button.tag = 2000; [button addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:button]; 31.让某个控件在View的中心位置显示：（某个控件，比如label，View）label.center = self.view.center; 32.好看的文字处理以tableView中cell的textLabel为例子： cell.backgroundColor = [UIColorscrollViewTexturedBackgroundColor]; //设置文字的字体 cell.textLabel.font = [UIFont fontWithName:@"AmericanTypewriter" size:100.0f]; //设置文字的颜色 cell.textLabel.textColor = [UIColor orangeColor]; //设置文字的背景颜色 cell.textLabel.shadowColor = [UIColor whiteColor]; //设置文字的显示位置 cell.textLabel.textAlignment = UITextAlignmentCenter; 33. ———————-隐藏Status Bar—————————– 读者可能知道一个简易的方法,那就是在程序的viewDidLoad中加入 [[UIApplication sharedApplication]setStatusBarHidden:YES animated:NO]; 33. 更改AlertView背景 UIAlertView *theAlert = [[[UIAlertViewalloc] initWithTitle:@"Atention" message: @"I'm a Chinese!" delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:@"Okay",nil] autorelease]; [theAlert show]; UIImage *theImage = [UIImageimageNamed:@"loveChina.png"]; theImage = [theImage stretchableImageWithLeftCapWidth:0topCapHeight:0]; CGSize theSize = [theAlert frame].size; UIGraphicsBeginImageContext(theSize); [theImage drawInRect:CGRectMake(5, 5, theSize.width-10, theSize.height-20)];//这个地方的大小要自己调整，以适应alertview的背景颜色的大小。 theImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); theAlert.layer.contents = (id)[theImage CGImage]; 34. 键盘透明 textField.keyboardAppearance = UIKeyboardAppearanceAlert; 状态栏的网络活动风火轮是否旋转 [UIApplication sharedApplication].networkActivityIndicatorVisible，默认值是NO。 35截取屏幕图片 //创建一个基于位图的图形上下文并指定大小为CGSizeMake(200,400) UIGraphicsBeginImageContext(CGSizeMake(200,400)); //renderInContext 呈现接受者及其子范围到指定的上下文 [self.view.layer renderInContext:UIGraphicsGetCurrentContext()]; //返回一个基于当前图形上下文的图片 UIImage *aImage = UIGraphicsGetImageFromCurrentImageContext(); //移除栈顶的基于当前位图的图形上下文 UIGraphicsEndImageContext(); //以png格式返回指定图片的数据 imageData = UIImagePNGRepresentation(aImage); 36更改cell选中的背景 UIView *myview = [[UIView alloc] init]; myview.frame = CGRectMake(0, 0, 320, 47); myview.backgroundColor = [UIColorcolorWithPatternImage:[UIImage imageNamed:@"0006.png"]]; cell.selectedBackgroundView = myview; 37显示图像: CGRect myImageRect = CGRectMake(0.0f, 0.0f, 320.0f, 109.0f); UIImageView *myImage = [[UIImageView alloc] initWithFrame:myImageRect]; [myImage setImage:[UIImage imageNamed:@"myImage.png"]]; myImage.opaque = YES; //opaque是否透明 [self.view addSubview:myImage]; 38.能让图片适应框的大小（没有确认） NSString*imagePath = [[NSBundle mainBundle] pathForResource:@"XcodeCrash"ofType:@"png"]; UIImage *image = [[UIImage alloc]initWithContentsOfFile:imagePath]; UIImage *newImage= [image transformWidth:80.f height:240.f]; UIImageView *imageView = [[UIImageView alloc]initWithImage:newImage]; [newImagerelease]; [image release]; [self.view addSubview:imageView]; 39.实现点击图片进行跳转的代码：生成一个带有背景图片的button，给button绑定想要的事件！ UIButton *imgButton=[[UIButton alloc]initWithFrame:CGRectMake(0, 0, 120, 120)]; [imgButton setBackgroundImage:(UIImage *)[self.imgArray objectAtIndex:indexPath.row] forState:UIControlStateNormal]; imgButton.tag=[indexPath row]; [imgButton addTarget:self action:@selector(buttonClick:) forControlEvents:UIControlEventTouchUpInside];

cxGrid右键菜单源码含源码 //CXVIEW的右键菜单 { Tag=19003 //TableView.Columns[i].Tag=19003 表示此列是计算列; } unit ABcxGridPopupMenuU; interface // 关闭RTTI反射机制减少EXE文件尺寸 {$IF CompilerVersion >= 21.0} {$WEAKLINKRTTI ON} {$RTTI EXPLICIT METHODS([]) PROPERTIES([]) FIELDS([])} {$IFEND} uses ABPubListBoxItemU,ABPubMemo

将tableView中的表头以及文本内容都进行居中处理 1、需要在构造函数中增加一句： //以下增加的是表头的效果 ui->tableView->horizontalHeader()->setSectionResizeMode(QHeaderView::Stretch);//布局排版是全部伸展开的效果 2、就是直接对tableView的文本内容开始进行居中的效果处理在将数据一个个的插入表中需要加入如下的代码，来达到居中的效果 QStandardItemModel* mode

eightNameCol.setStyle( "-fx-alignment: CENTER;"); 哎，搞了好多天才弄好
