如何使 QTableWidget 中的单元格只读？

发布于 2024-12-09 15:45:35 字数 1186 浏览 5 评论 0原文

我有以下代码定义我的应用程序的 gui

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

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编辑它们，但我想锁定一些单元格。（我已经有扩展表格的代码）如何使某些单元格只读，同时保持其他单元格读写？我找到了这个链接 How to make a columns in QTableWidget read only? 以及 C++ 中问题的解决方案，python 解决方案是否类似？

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

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 ?

我玩了一下代码并阅读了更多文档
问题的答案是

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)

解决方案是“item.setFlags(QtCore.Qt.ItemIsEnabled)”行，您使用它来将单元格属性QtCore.Qt.ItemIsEnabled设置为禁用，因此您无法选择或编辑单元格

您可以按照 http://doc.qt.io/archives/qt-4.8/qt.html 在 Qt::ItemFlag 部分下，

如 Sven 对此问题的第二个答案的评论中所述，如果 QTableWidgetItem 中有静态数量的行和列，则可以使用 Qtdesigner 选择单元格的属性（如果您使用 Qtdesigner 为应用程序创建屏幕）

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)

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

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

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

当没有编辑触发器时，永远不会进入 QTableWidgetItem 的编辑状态：

self.tableName.setEditTriggers(QtGui.QAbstractItemView.NoEditTriggers)

就像Sven Krüger的答案一样，您也可以将此方法用于PyQt5 :

self.tableWidget.setEditTriggers(QtWidgets.QTableWidget.NoEditTriggers)

Like Sven Krüger's answer, you can also use this methods for PyQt5:

self.tableWidget.setEditTriggers(QtWidgets.QTableWidget.NoEditTriggers)

如果您希望 UI 看起来相同（仍然可以选择，并变成蓝色，但不可编辑），我发现 QtCore.Qt.ItemIsEditable 给出了很好的结果。

item = QtWidgets.QTableWidgetItem()
item.setFlags(item.flags() ^ QtCore.Qt.ItemIsEditable)
self.table_widget.setItem(row, column, item)

If you want the UI to look the same (have it still selectable, and turn blue, but just not editable) I found QtCore.Qt.ItemIsEditable gave good results.

item = QtWidgets.QTableWidgetItem()
item.setFlags(item.flags() ^ QtCore.Qt.ItemIsEditable)
self.table_widget.setItem(row, column, item)

对于 PyQt6，它与 @ozcanyarimdunya 相同，但具有枚举 EditTrigger：

self.tableWidget.setEditTriggers(QTableWidget.EditTrigger.NoEditTriggers)

For PyQt6, it's the same as @ozcanyarimdunya but with the enum EditTrigger:

self.tableWidget.setEditTriggers(QTableWidget.EditTrigger.NoEditTriggers)

如果你想让整个表格不可编辑，请尝试以下操作：

for row in range(self.tableName.rowCount()):
    for col in range(self.tableName.columnCount()):
        self.tableName.item(row,col).setFlags(Qt.ItemFlag.ItemIsEditable)

if you want to make the whole table is not editable try this:

for row in range(self.tableName.rowCount()):
    for col in range(self.tableName.columnCount()):
        self.tableName.item(row,col).setFlags(Qt.ItemFlag.ItemIsEditable)
