qtableview

I want to delete a selected row from the table when I click on the delete button. But I can't find anything regarding deleting rows in the Qt documentation. Any ideas? You can use the bool QAbstractItemModel::removeRow(int row, const QModelIndex & parent = QModelIndex()) functionality for this. Here you can find an example for all this. Also, here is an inline quote from that documentation: removeRows() Used to remove rows and the items of data they contain from all types of model. Implementations must call beginRemoveRows() before inserting new columns into any underlying data structures, and

I have a QTableView in a PyQt application, and I want to keep track of when the selection changes. I've tried connecting the signal to a slot as follows (using the advice on this page : self.view.selectionModel().selectionChanged.connect(self.selChanged) where the slot it is connected to is defined as: def selChanged(self, selected, deselected): print "Sel changed" However, whenever I load the QMainWindow on which the QTableView resides, I get an immediate segmentation fault. Am I doing something silly here? eric I was having a similar problem and the fix was here: PySide: Segfault(?) when

I have a MySql table, let's call it x : CREATE TABLE x ( Id int unsigned NOT NULL PRIMARY KEY AUTO_INCREMENT, A int unsigned NOT NULL, B int, FOREIGN KEY (A) REFERENCES y(Id) ); And then I have another table, let's call it y : CREATE TABLE y ( Id int unsigned NOT NULL PRIMARY KEY AUTO_INCREMENT, First varchar(255), Last varchar(255) ); I want to display table x in one QTableView and in place of column A from table x I want to display columns First and Last from table y from row whose Id is equal to A from table x . Do you have any ideas? Let me know if my explanation is not clear enough. You

I'm doing an implementation of a CheckBox that inherits from QitemDelegate, to put it into a QTableView. the problem is that I get when inserted flush left and I need it centered. As I understand the method that is responsible for the Paint. I have it written as follows: void CheckBoxDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const { bool checkValue; QStyleOptionButton BtnStyle; BtnStyle.state = QStyle::State_Enabled; if(index.model()->data(index, Qt::DisplayRole).toBool() == true) { BtnStyle.state |= QStyle::State_On; checkValue = true;

I followed the Spin Box Delegate tutorial, which Qt provides, to try to implement my own QItemDelegate . It would be used to specify a QComboBox to represent data in a QTableView cell but it is not working. My biggest problem is that I don't know when my QItemDelegate is going to be utilized. when itemModel->setData() is used or when itemModel->setItem() . I would suspect setItem() because I reimplemented a QItemDelegate (emphasis on the "Item") but the tutorial uses setData() and it works fine. I know that if the specified QItemDelegate does not work it uses the default one but how do I now
