问题 My application starts with an empty table, and I want to imlement different methods to add items. One should be by double-clicking the table's unused area (or "background") that is not occupied by any cells. When a cell is double-clicked, I want the default behavior. I've found way to do this by re-implementing QAbstractScrollArea::mouseDoubleClickEvent() method in my TestTable class: #include <QMouseEvent> #include <QTableView> class TestTable : public QTableView { Q_OBJECT signals: void

Create PushButtons in QTableView with QStyledItemDelegate subclass

阅读更多关于 Create PushButtons in QTableView with QStyledItemDelegate subclass

问题 I have the exact same problem, but I will use the QTableView widget. I read this and was wondering if I can override the createEditor function to use for instance QFileDialog to get the new data. If this is possible, can anyone provide me with an example to implement such a subclass to QItemDelegate. And if not, can anyone provide me with an example to implement a subclass to QItemDelegate, witch can draw a button next to a QLineEdit to get the functionality here. Edit: Maybe this question is

下面想象一个这样的场景，你的数据库有一个表中储存有用户信息，姑且称为user表。 .schema user CREATE TABLE user(id integer,name text,telphone text,unique(id)); 表user中储存有 id：相当于用户的实际ID，唯一 name: 用户的用户名，供显示或者登录的时候使用 telphone:一个附加信息，电话号码一般我们程序中还会有一个储存用户数据的表，这里引用为data表,里面储存的是一些用户数据，完全可以自定义。在多用户的情况下我们一般会添加一个字段user_id来表示这个数据的所属用户。 .schema data CREATE TABLE data(message text,time datetime,user_id integer); 这是一个简单的场景，现在我们的需求是提供一个用户界面，可以显示出姓名，时间，信息我们需要怎么做呢，（这里不提我曾经见过的一个中规模程序中逻辑控制拼接这些信息的了，代码冗余且丑陋，性能更不用提～）我们在数据库中创建一个view来解决（引用为view1）： .schema view1 CREATE VIEW view1 as select (select name from user where id=data.user_id) as name,time

PyQt: QTableView + QSqlTableModel - Copy and Paste All Selected Rows or Columns into Notepad or Excel

阅读更多关于 PyQt: QTableView + QSqlTableModel - Copy and Paste All Selected Rows or Columns into Notepad or Excel

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?
