I am trying to delete all rows from a QTableWidget . Here is what I tried. for ( int i = 0; i < mTestTable->rowCount(); ++i ) { mTestTable->removeRow(i); } I had two rows in my table. But this just deleted a single row. A reason could be that I did not create the the table with a fixed table size. The Qt Documentation for rowCount() says, This property holds the number of rows in the table. By default, for a table constructed without row and column counts, this property contains a value of 0. So if that is the case, what is the best way to remove all rows from table? Just set the row count to

I am trying to set background color of TableWidget based on certain value from data loaded from Sqlite database like in example below . I have seen below answer in PyQt Tableview background color based on text value rather than True or False which works . Problem is , In my setup I use TableWidget with a Button ( I used Qt Designer ) that loads the data from Sqlite database and I am not too sure how to implement below code into my setup as I dont entirely understand how it works: def data(self, item, role): if role == Qt.BackgroundRole: if QSqlQueryModel.data(self, self.index(item.row(), 2),

Is it possible to make one cell a formula driven cell and have it update automatically? Similar to Excel. For example, I want user to fill out two cells, and then a third cell will automatically divide when user fills both cells. I'd like it to be NOT connected to a button. QTable Screenshot Code for TableWidget: self.tableWidget = {} for i in range(int(self.numberLine.text())): self.tableWidget[i] = QTableWidget() self.tableWidget[i].setRowCount(5) self.tableWidget[i].setColumnCount(3) self.tableWidget[i].setHorizontalHeaderLabels(['OEM (Case {})'.format(i+1), 'ZVI (Case {})'.format (i+1),

I have a QTableWidget that I've set up such that you can't select the cells, but can select rows/columns by their headers. The problem I'm having is when I select a row, it deselects any columns that were selected, and same for column/rows. I want to be able to select rows with the ExtendedSelection behavior and columns with the SingleSelection behavior, but independently of eachother. Here's what I'm doing: ui->tableWidget->setSelectionMode(QAbstractItemView::NoSelection); connect(ui->tableWidget->horizontalHeader(),SIGNAL(sectionClicked(int)), this,SLOT(horizontalHeaderClicked(int)));

Currently, if the user clicks on a cell that is only partially visible, the window automatically scrolls over so that the cell is fully displayed. Is there any way to stop the table doing this? Thanks The scrolling is done by QAbstractItemView which call the virtual function scrollTo with index the hint EnsureVisible . You can't prevent the call, because it is done through a private timer, but you can change what the scrollTo function does: void TableWidget::scrollTo(const QModelIndex &index, ScrollHint hint) { if(hint == QAbstractItemView::EnsureVisible) return; QTableWidget::scrollTo(index,
