问题 I want to have a tablewidget that will color some of the rows based on certain conditions and threshold. For example, if the data in one column reaches over 20, it will color the row where that 20 was. What i have only searches through the Qtablewidgetitem and it does not do what I want it to do. def setmydata(self): for n, key in enumerate(self.data): for m, item in enumerate(self.data[key]): newitem = QtGui.QTableWidgetItem(item) c = newitem.column() + 2 print c for items in item: if

问题 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. 回答1: 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

问题 I am using PyQt for a simple application that reads from a log file with JSON formatted strings, and outputs them nicely in a table. Everything is working as expected except when I try to emit a signal from a 'load' function. This signal is picked up by the main window, in a slot designed to resort the table with new information. Without the signal emitted, the table populates fully and properly: By uncommenting the self.emit so that the signal IS emitted, the table ends up being incomplete:

问题 I made a form in QtDesigner. This form gets loaded from PySide with help of the function widget = loader.load(file, parent) However, the QTableWidget (with objectNname buffer_table) don't get accessible with widget.buffer_table If I use a QPushButton instead it works. How can I get this working. I'd like to fill up the table in Python. This is the ui-file i'd like to use: http://pastebin.com/6PZFrvmr EDIT: When I create a new table and try to load it, it seems to work. However, if I put it in

问题 I work eith pyqt4 in python3.4 I want to validate if the text in the cell is a float number when it is introduced. How I do that? 回答1: You have two options. You can create a QItemDelegate and override the createEditor , setEditorData and setModelData to control the widget they're presented with to edit the data. You can create a QLineEdit with a validator if you'd like, but if they can only enter a number, you should probably just use a QSpinBox or QDoubleSpinBox , which only allow integers

问题 I want to highlight the row on mouse hover in my QTableWidget . When I hover the mouse, only single cell highlighted. I have tried this approach : bool MyTabWidget::eventFilter(QObject *target, QEvent *event) { if( target == ui->MyTableWidget ) { //Just to print the event type qDebug() <<"EventType : "<<event->type(); } } Output : EventType : 13 . `(13 = QEvent::Move)` I have done lost of googling. but not get any proper solution. Is there any other approach to fulfill my requirment (to

问题 I would like to have one column in QTableWidget NOT editable. In forums I have read a lot about some flags but could not manage to implement. 回答1: Insert into the QTableWidget following kind of items: QTableWidgetItem *item = new QTableWidgetItem(); item->setFlags(Qt::ItemIsSelectable|Qt::ItemIsEnabled); Works fine! EDIT: QTableWidgetItem *item = new QTableWidgetItem(); item->setFlags(item->flags() ^ Qt::ItemIsEditable); This is a better solution. Thanks to @priomsrb. 回答2: The result of using

问题 I have a QTablewidget , it can add rows and columns. Values can be inserted by user. I know how to get a single value of a cell by using current.item() method. But think and look at below image. User can insert different values and texts. I like to read a row values by its own. because I need to use values later. but I do not know how and where could values be read dynamically and still have a method to tell for exampel if a value under C is valid or not. Visualization: Here sees values at

问题 I'm trying to fill a QTableWidget from a file that was exported by my program, but when I try to set text to the table cells they just ignore me, nothing happens. void MainWindow::on_actionOpen_Project_triggered() { QString line, fileName; fileName = QFileDialog::getOpenFileName(this,tr("Open Project"), "", tr("Project Files (*.project)")); if(!fileName.isEmpty()){ QFile file(fileName); if (!file.open(QIODevice::ReadOnly | QIODevice::Text)) return; QTextStream in(&file); for(int i=0;i<ui-
