qtableview

问题 To start, I've already looked at ekhumoro's code on a nearly similar subject Here. However, when I attempt to implement this code, I am getting a different result. Instead of copying and pasting all the I selected, it only copies the first cell of the selected row or rows respectively. I need users to be able to select multiple rows or columns and paste those values in either excel or notepad. Any ideas? GUI: Code: from PyQt4 import QtCore, QtGui, QtSql import sys import sqlite3 import time

问题 The line self.tableView.setSortingEnabled(True) sorts a table view when clicking on the header, but it sorts incorrectly. That is, it thinks every column is a string (e.g. it sorts numbers like 1,11,12,2,22,3 , etc). How do I correct this? My code: self.model = QtGui.QStandardItemModel() with open(file_name_temp, "rt") as fileInput: i = 1 for row in csv.reader(fileInput): item = QtGui.QStandardItem() for field in row: items = [ item.setData(field, QtCore.Qt.UserRole) ] print(items) self.model

问题 Is there a way to drag rows out of a QTableView? I know how to internally move columns within a QTableView by configuring some properties on the view: table_view_->horizontalHeader()->setSectionsMovable(true); table_view_->horizontalHeader()->setDragEnabled(true); table_view_->horizontalHeader()->setDragDropMode(QAbstractItemView::InternalMove); Going through the documentation on QAbstractItemView::DragDropMode , I intuitively expected my following attempt to allow external dragging of

问题 I wrote the below code for a qt gui to view the query output in a QTableView(Model oriented). now i want to save this output as a .csv or .txt file. There were suggestions to use QTableWidget(Item oriented) but I would like to stick to the model based approach. void MainWindow::on_pushButton_clicked() { db = QSqlDatabase::addDatabase("QOCI"); db.setHostName("host"); db.setDatabaseName("db"); db.setUserName("uid"); db.setPassword("pw"); db.setPort(port); QString MyQuery = ui->lineEdit->text();

问题 I have a problem with the line below self.tableView.set??????????(df) that supposed to display the data frame in PyQt5. I put ??? there where I am missing the code I need. def btn_clk(self): path = self.lineEdit.text() df = pd.read_csv(path) self.tableView.set??????????(df) The rest of the code works, because if I use print(df) in the above code, the data frame is printed in the IPython console. So, Pandas reads the CSV and prints it. But, I tried many things to get it displayed in PyQt5 and

问题 Recently, I made the switch to QT. It has taken some time, but I am starting to find my way around. However, one issue remains: I want to port a program, that responds to every key press while editing a cell in a table view (QTableView with QStandardItemModel). The idea is to show and update a list of possibilities on a separate form while the user is entering a text in a table view's cell. After every key stroke, the list needs to be updated according to the current text in the edit field of

问题 I am creating a table inside of a PyQt5 GUI using QTableView. I have 35 rows and 5 columns from a pandas dataframe. Scrolling and sorting the table is extremely slow (on the order of seconds). I have already looked for solutions, but most people were having trouble with populating the table. One person suggested using a numpy array, but I did not see any increase in performance. Here is my code: def create_table(dataframe): table = QTableView() tm = TableModel(dataframe) table.setModel(tm)

问题 I am using the code in this answer to add checkbox in tableview. I want to show it in the first column. Here is my code: mysqlquerymodel.h #ifndef MYSQLQUERYMODEL_H #define MYSQLQUERYMODEL_H #include <QObject> #include <QMap> #include <QModelIndex> #include <QSqlQueryModel> class MySqlQueryModel : public QSqlQueryModel { Q_OBJECT public: explicit MySqlQueryModel(QObject *parent = 0); Qt::ItemFlags flags(const QModelIndex & index) const; QVariant data(const QModelIndex & index, int role) const

问题 Clicking the QTableView " Item_B_001 " prints out its row number # 0 . But in source model's self.items this item corresponds to the number # 3. How to get a "real" Source Model's Item's row number - a number it really corresponds to? from PyQt4.QtCore import * from PyQt4.QtGui import * import sys class Model(QAbstractTableModel): def __init__(self, parent=None, *args): QAbstractTableModel.__init__(self, parent, *args) self.items = ['Item_A_001','Item_A_002','Item_B_001','Item_B_002'] def
