qtablewidget

i have the following code defining the gui of my app class Ui (object): def setupUi(): self.tableName = QtGui.QTableWidget(self.layoutWidget_20) self.tableName.setObjectName(_fromUtf8("twHistoricoDisciplinas")) self.tableName.setColumnCount(4) self.tableName.setRowCount(3) and the following code in my app class MainWindow(QtGui.QMainWindow): def __init__(self): self.ui = Ui() self.ui.setupUi(self) self.createtable() #creating a tw cell def cell(self,var=""): item = QtGui.QTableWidgetItem() item.setText(var) return item def createtable(self): rows = self.tableName.rowCount() columns = self

I am student programmer and I am using Qt to develop a GUI interface for work and Im having trouble figuring out how I should make this this import function work. A bit of programmers writers block if you will. SO far I have this for code: void InjectionLocationsDialogExpanded::importCSVFile() { QString fileName = QFileDialog::getOpenFileName(this, ("Open File"), "/home", ("csv File(*.csv)")); QString data; QFile importedCSV(fileName); QStringList rowOfData; QStringList rowData; int tempint = 0; data.clear(); rowOfData.clear(); rowData.clear(); if (importedCSV.open(QFile::ReadOnly)) { data =

what I want to do is to change the color of a QTableWidget item, when I hover with the mouse over the item of my QTableWidget. Firstly, the table widget needs to have mouse-tracking switched on to get the hover events. Secondly, we need to find some signals that tell us when the mouse enters and leaves the table cells, so that the background colours can be changed at the right times. The QTableWidget class has the cellEntered / itemEntered signals, but there is nothing for when the mouse leaves a cell. So, we will need to create some custom signals to do that. The TableWidget class in the demo

Consider a QTableWidget and two buttons "move up" and "move down". Clicking on move up, the current row should move up one row, analogously for "move down". What's the easiest way to implement the corresponding move up and move down functions? I have revised my answer because it did not have enough detail previously The process involves connecting your buttons to a slot (or slots) that will look at the current selection, and move them by taking them from the view, and inserting them into new locations. The following example is actually using a QTableView + QStandardItemModel. The reason is

I want to merge(span) horizontal headers in QTableWidget . I tried googling for the same, but no luck and hence posting it. Please guide me. You can subclass QHeaderView and create one section for each of the groups of columns/rows you would like to span and connect signals and slots to have them react to the different columns/rows. The following example is for spanning the horizontal header: #include <QtGui> class MyHeaderModel : public QAbstractItemModel { public: MyHeaderModel(QObject *parent = 0) : QAbstractItemModel(parent) {} int columnCount(const QModelIndex &parent = QModelIndex())

I have custom widget made with qt designer and i want to add it to QTableWidget cell. But it doesn't work. Here is the code : int nRows =10; for(int row = 0; row < nRows;row++;) { QTableWidgetItem* item = new QTableWidgetItem(); CustomWdg* wdg=new CustomWdg( ); mTableWdg->insertRow( row ); mTableWdg->setItem(row, 0, item); mTableWdg->setCellWidget( row, 0, wdg ); } If you want to add custom widget into table cell you can use QItemDelegate. Create your own Delegate class and inherit it from QItemDelegate. class MyDelegate : public QItemDelegate { public: CChoicePathDelegate (QObject *parent = 0
