[英]Python PyQt5 - How to rename table headers?
I have a function that adds new column to the table, hoewer I do not know how to rename the column header.我有一个 function 向表中添加新列,但是我不知道如何重命名列 header。 What I want is for the user to either double click on the column header so that you could edit the column header.
我想要的是用户双击列 header 以便您可以编辑列 header。 or what I have now: I have aa button that adds a new column and line Edit where you write your column name.
或者我现在拥有的:我有一个按钮,可以添加一个新列和行编辑,您可以在其中写入列名。
I do not know how to rename the column header names我不知道如何重命名列 header 名称
This is my code that handles adding new column to the table.这是我处理向表中添加新列的代码。
def addNewColumn(self):
self.tableColumn = self.table_Database.columnCount()
self.table_Database.setColumnCount(self.tableColumn + 1)
self.table_Database.setItem(0,self.tableColumn,QtWidgets.QTableWidgetItem())
if self.table_Database.rowCount() == 0:
self.table_Database.setRowCount(1)
self.table_Database.setItem(1,0,QtWidgets.QTableWidgetItem())
SOLUTION/FIX: So here is the fix, I have also added an error message that will be displayed if the column doesn't carry a name, if it doesn't the column will not be added解决方案/修复:所以这是修复,我还添加了一条错误消息,如果该列没有名称,将显示该错误消息,如果没有,则不会添加该列
def addNewColumn(self):
self.error_message = QtWidgets.QErrorMessage()
if self.addNewColumnName_TEXT.text() == '':
self.error_message.showMessage('Column doesn't have a name')
else:
self.tableColumn = self.table_Database.columnCount()
self.table_Database.setColumnCount(self.tableColumn + 1)
self.table_Database.setItem(0,self.tableColumn,QtWidgets.QTableWidgetItem())
self.__tableHeader_Labels.append(self.addNewColumnName_TEXT.text())
self.table_Database.setHorizontalHeaderLabels(self.__tableHeader_Labels)
if you use a model.. See headerData... it defines the horizontal header... columns.如果您使用 model.. 请参阅 headerData... 它定义了水平 header... 列。
class TableModel(QtCore.QAbstractTableModel):
def __init__(self, data):
super(TableModel, self).__init__()
self._data = data
def headerData(self, p_int, Qt_Orientation, role=None):
if role == Qt.DisplayRole and Qt_Orientation==Qt.Horizontal:
header = ['Symbol', 'Time', 'Price', 'Current Price','Orig Qty', 'Executed Qty', 'Type']
return header[p_int]
else:
return QtCore.QAbstractTableModel.headerData(self, p_int, Qt_Orientation, role)
def data(self, index, role):
if role == Qt.DisplayRole:
# See below for the nested-list data structure.
# .row() indexes into the outer list,
# .column() indexes into the sub-list
return self._data[index.row()][index.column()]
def rowCount(self, index):
# The length of the outer list.
return len(self._data)
def columnCount(self, index):
# The following takes the first sub-list, and returns
# the length (only works if all rows are an equal length)
return len(self._data[0])
