如何使 QTableWidget 中的单元格只读? [英] how to make a cell in a QTableWidget read only?

问题描述

我有以下代码定义我的应用程序的 gui

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)

以及我的应用程序中的以下代码

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.tableName.columnCount()
         for i in range(rows):
             for j in range(columns):
                 item = self.cell("text")
                 self.ui.tableName.setItem(i, j, item)

我希望能够添加新的行和列并对其进行编辑，但我想锁定某些单元格.(我已经有了扩展表格的代码)如何在保持其他单元读写的同时使某些单元格只读?我找到了这个链接 How to make a column in QTableWidget read only? 用 C++ 中的问题解决方案，python 解决方案是否类似?

I want to be able to add new rows and columns and edit them but i want to lock some of the cells. ( i already have code that expand the table ) how can i make some cells read only while keeping the others read write? i found this link How to make a column in QTableWidget read only? with a solution for the problem in C++, is python solution similar ?

推荐答案

我玩了一下代码并阅读了更多文档问题的答案是

I played a little with the code and read some more documentation the answer to the problem is

def createtable(self):
     rows = self.tableName.rowCount()
     columns = self.tableName.columnCount()
     for i in range(rows):
         for j in range(columns):
             item = self.cell("text")
             # execute the line below to every item you need locked
             item.setFlags(QtCore.Qt.ItemIsEnabled)
             self.ui.tableName.setItem(i, j, item)

<小时>

解决办法是item.setFlags(QtCore.Qt.ItemIsEnabled)"这一行，你用它来设置单元格属性QtCore.Qt.ItemIsEnabled为disabled，这样就不能选择或编辑单元格了

---

The solution is the line "item.setFlags(QtCore.Qt.ItemIsEnabled)", you use it to set the cell property QtCore.Qt.ItemIsEnabled to disabled, so you can't select or edit the cell

根据 上的文档，您可以在运行时以这种方式更改许多其他属性http://doc.qt.io/archives/qt-4.8/qt.html 在 Qt::ItemFlag

You can change a number of other properties this way at runtime as per documentarion on http://doc.qt.io/archives/qt-4.8/qt.html under the section Qt::ItemFlag

正如 Sven 在对这个问题的第二个答案的评论中提到的，如果您的 QTableWidgetItem 中有静态数量的行和列，您可以使用 Qtdesigner 选择单元格的属性，如果您使用它来创建屏幕您的申请

as mentioned in a comment by Sven on the second answer to this question, if you have a static number of rows and columns in your QTableWidgetItem you can select the properties of the cells with Qtdesigner if you use it to create the screens for your application
