We're using a custom subclass of QAbstractTableModel as the model for the QTableView . Right now, we have a checkbox by setting the Qt::ItemIsUserCheckable flag. But we can't figure out how to get rid of the blank textbox next to the checkbox! How can we make the column only have a checkbox, nothing else? 回答1: Here is a solution. For this to work properly, your column should not have the Qt::ItemIsEditable or Qt::ItemIsUserCheckable flags set.

If i filter one column using certain value, and with the filtered data, if i try to filter second column, last filter gets reset and data are displayed corresponding to filter on second column. I want to achieve multiple column filter on Qtableview. Code snippet: self.tableView = QTableView() self.model = QtGui.QStandardItemModel(self) self.proxy = QtGui.QSortFilterProxyModel(self) self.proxy.setSourceModel(self.model) self.tableView.setModel

When I open a window, it look ok but when i resize the window, the QTableView itself gets resized but columns' width remains the same. Is there any build-in way to make it work? I want columns to resize to fit the edges of QTableView every the the window gets resized. 回答1: There is a header flag to ensure that the QTableView's last column fills up its parent if resized. You can set it like so: table_view->horizontalHeader()-

I am able to hover a single cell on mouse over: void SchedulerDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const { ... if(option.showDecorationSelected &&(option.state & QStyle::State_Selected)) { QColor color(255,255,130,100); QColor colorEnd(255,255,50,150); QLinearGradient gradient(option.rect.topLeft(),option.rect.bottomRight()); gradient.setColorAt(0,color); gradient.setColorAt(1,colorEnd); QBrush brush(gradient); painter

QSqlQueryModel 类为SQL结果集提供了只读数据模型。所以当前示例只显示不操作。 如果想在视图直接操作数据库内容，需要自己封装一个类且继承 QSqlQueryModel，重写里面的虚函数。 #include <QtSql/QSqlDatabase> #include <QtSql/QSqlQuery> #include <QtSql/QSqlQueryModel> QSqlDatabase * m_db ; QSqlQuery * m_qy ; QSqlQueryModel * m_model ; 第一步//打开数据库 m_db = new QSqlDatabase ; * m_db = QSqlDatabase :: addDatabase ( "QMYSQL" ); //链接MYSQL的驱动 m_db -> setHostName ( "127.0.0.1" ); //设置主机名 m_db -> setPort ( 3306 ); //配置端口号 m_db -> setDatabaseName ( "myDBtest" ); //打开"myDBtest"数据库 m_db -> setUserName ( "root" ); //账号 m_db -> setPassword ( "root" ); //密码 if ( m_db -> open ()){ qDebug

I have QTableView and QAbstractTableModel . I require rows to have height equal to 24. I know the only way to do this is by calling QTableView::setRowHeight . Since the model is dynamic it may be added new rows, but I don't want to call setRowHeight each time new row is added. How can I configure QTableView such that it uses the same height for new added rows or can a model be sent the height of rows? For Qt versions < 5 QHeaderView *verticalHeader = myTableView->verticalHeader(); verticalHeader->setResizeMode(QHeaderView::Fixed); verticalHeader->setDefaultSectionSize(24); For Qt versions >= 5

I am using QTableView to display data retrieved from QtSql.QSqlQuery I want to know how can i create filters for it like in excel. In the above image i need to get the filters for All heders (Sh_Code,SH_Seq,Stage) The filters will have unique values in of that column on which we can filter. Required result I need the Table view header with a dropbox listing all unique values in that column just like in excel below. No need of Top,Standard filter... as shown in image. Need only "All" and the unique "column items" This is from my .NET application, uploaded for more clarity Here is an example of

This is a follow up question to: PyQt: How to sort QTableView columns(strings and numericals) Now I am planning to do the same sorting for the excel files Here is my Code: self.Upload = QtGui.QPushButton() self.Upload.clicked.connect(self.showOpenDialog) self.Table = QtGui.QPushButton() self.table.clicked.connect(self.LoadTable) def showOpenDialog(self): fileName = QtGui.QFileDialog.getOpenFileName(self, 'Open file', '/home') if (".xls" or ".xml" or ".xlsx" or ".xlsm") in fileName: with open(fileName, 'rb') as drate: self.Datas = pd.read_excel(drate, index_col=0) self.Loaded_File.clear() self
