cellDoubleClicked 文本 python [英] cellDoubleClicked text python

问题描述

我在使用 PyQt5 时遇到了一个问题，我已经制作了一个 QTableWidget，它显示了我之前在 Pandas 中制作的 DataFrame(来自电子表格).

Im dealing with a problem when using PyQt5, i already made a QTableWidget which displays a DataFrame i prevously made in pandas (from a spreadsheet).

我尝试不成功的是:从用户双击的单元格中获取文本，以便我可以使用该信息根据所做的选择构建一个新的小部件.

What im trying unsuccesfully to do is: Get the text from the cell that the user double-clicks so i can use that information to build up a new Widget based on choice made.

我学到的是，我首先需要将双击连接到一个函数，但之后我无法继续:

What i've learned is that i first need to connect the double-click to a function, but i cant continue afterwards:

我在 QTableWidget 上的连接如下:

my connection on my QTableWidget goes as follows:

(在我的 MainWindow 小部件下)

(Under my MainWindow Widget)

self.tableView.cellDoubleClicked.connect(self.expandShipments)

然后我声明这个信号连接的函数(expandShipments)"

"Afterwards i declare the function to which this signal connects (expandShipments)"

def expandShipments(self):

 *** code i need to get doubleClicked cell text ***

我真的很感激这个案例.

I'd really appreciate a hand with this case.

这是我的表格填充方式.

This is the way my table is populated.

QTableWidget.

QTableWidget.

def loadFile(self):
    fileName='C:/Users/310287757/Desktop/JLG/Programming/tstBIGDF.xlsx'
    df = pandas.read_excel(fileName, sheetname='MAIN', header=0)  # read file and set header row
    df= df.loc[df['Name Opp'] == self.comboProy.currentText()]
    self.tableView.setColumnCount(len(df.columns))
    self.tableView.setRowCount(len(df.index))
    tags=[]
    for ele in list(df.columns.values):
        tags.append(ele)

    self.tableView.setHorizontalHeaderLabels(tags)
    for i in range(len(df.index)):
        for j in range(len(df.columns)):
            self.tableView.setItem(i, j, QTableWidgetItem(str(df.iat[i, j])))

    self.tableView.resizeColumnsToContents()
    self.tableView.resizeRowsToContents()
    PPen = df['Pending amount'].values.sum()
    PTot = df['total item amount'].values.sum()
    PP=("Pendiente por facturar: U$S %.2f"% PPen)
    PT=("Total: U$S %.2f" % PTot)
    self.lblPEND.setText(PP)
    self.lblTOTAL.setText(PT)

    del df,fileName,tags

推荐答案

cellDoubleClicked 信号发送行和列.所以你的代码应该是这样的:

The cellDoubleClicked signal sends the row and column. So your code should look like this:

self.tableView.cellDoubleClicked.connect(self.expandShipments)
...

def expandShipments(self, row, column):
    item = self.tableView.item(row, column)
    print(item.text())
