pyqt in QTableWidget the drop-down list

Stumbled on a giant cow artificial intelligence course, could not help but share to everyone. Tutorial is not only a zero-based, user-friendly, and very humorous, like watching a fiction! I think too much bad, so to others. Tutorial links: https://www.cbedai.net/qtlyx       

 

Sometimes we want to choose the drop-down list in the cell QTableWidget's like this excel inside. So how to set it? How to achieve read and write it? Especially in pyqt, in a c ++, the Internet has been a lot of examples.

1, write

 for row in range(len(index_list)):
                for col in range(len(col_list)):
                    if row in [2, 3, 4]:
                        table.setItem(row, col, QTableWidgetItem(
                            str(df.loc[df.index[row], df.columns[col]])))
                    elif row == 0:
                        comBox_direction = QComboBox()
                        comBox_direction.addItems(["买", "卖"])
                        comBox_direction.setStyleSheet("QComboBox{margin:3px};")

                        if df.loc[df.index[row], df.columns[col]] == "买":
                            comBox_direction.setCurrentIndex(0)
                        elif df.loc[df.index[row], df.columns[col]] == "卖":
                            comBox_direction.setCurrentIndex(1)
                        table.setCellWidget(row, col, comBox_direction)
                    elif row == 1:
                        comBox_call_put = QComboBox()
                        comBox_call_put.addItems(["看涨", "看跌"])
                        comBox_call_put.setStyleSheet("QComboBox{margin:3px};")
                        if df.loc[df.index[row], df.columns[col]] == "看涨":
                            comBox_call_put.setCurrentIndex(0)
                        elif df.loc[df.index[row], df.columns[col]] == "看跌":
                            comBox_call_put.setCurrentIndex(1)
                        table.setCellWidget(row, col, comBox_call_put)

Let's look at the code above. This code is used to refresh the QtableWidget, and the value of the table consistent dataframe. General assignment is simple:

table.setItem(row, col, QTableWidgetItem(
                            str(df.loc[df.index[row], df.columns[col]])))

So if you want to assign to a QComboBox it? It is also very simple, first instantiate a QComboBox objects:

comBox_direction = QComboBox()
comBox_direction.addItems(["买", "卖"])
comBox_direction.setStyleSheet("QComboBox{margin:3px};")

Then, bound to the table:

table.setCellWidget(row, col, comBox_direction)

 

 

Let's look at the code above. This code is used to refresh the QtableWidget, and the value of the table consistent dataframe. General assignment is simple:

2, Reading

So, when we want to read the table in QComBox, how to do it?

combox_context_llist = [table.cellWidget(i, col).currentText() for i in range(0, 1)]

When we get content combox time, and that is the time to write, in turn, use cellWidget, rather than item.

 

Well, ending with a python students can also achieve a combination of a table and combox.
