要在导入Excel至QTableView时显示实时进度条,你可以使用QProgressDialog。
以下是一个简单的示例代码:
```python
from PyQt5.QtWidgets import QFileDialog, QProgressDialog
def import_excel(self):
file_name, _ = QFileDialog.getOpenFileName(self, "Open Excel file", "", "Excel Files (*.xlsx *.xls)")
if file_name:
# get rows and columns from Excel file
# ...
# set up progress dialog
progress_dialog = QProgressDialog("Importing...", "Cancel", 0, rows, self)
progress_dialog.setWindowTitle("Import Excel")
progress_dialog.show()
# read data from Excel file and insert into QTableView
for row in range(rows):
# insert data into QTableView
# ...
# update progress dialog
progress_dialog.setValue(row)
if progress_dialog.wasCanceled():
break
progress_dialog.close()
```
在这个示例中,我们首先使用QFileDialog获取Excel文件的文件名。然后,我们获取Excel文件的行数和列数,并设置QProgressDialog。在读取Excel文件中的数据并插入到QTableView中的过程中,我们使用progress_dialog.setValue()来更新进度条的值。如果用户点击了“取消”按钮,我们就使用progress_dialog.wasCanceled()检查用户是否取消了操作,并在需要时停止导入过程。
请注意,这只是一个简单的示例,您可能需要根据您的具体需求做一些修改。
