将所有项目设置为 PyQt5 的默认值(标签除外)的方法? [英] Way to set all items to defaults of PyQt5 except labels?

问题描述

我创建了一个框架并向该框架添加了许多 pyqt5 项目.

I have created a frame and added many pyqt5 items to that frame.

添加表单后，我想将框架的所有项目清除为默认空白值.我可以通过 .clear() 方法设置单个项目来做到这一点.

After adding the form, I want to clear all the items of the frame to default blank values. I can do that by setting individual items by .clear() method.

有什么办法可以一次性清除框架或选项卡中的所有项目以清除(或默认)值?

Is there any way where I can clear all the items in a frame or tab to clear(or default) values at one go?

推荐答案

没有清除所有输入的方法.一个简单的解决方案是使用 findChildren 方法遍历小部件:

There is no method that cleans all the inputs. A simple solution is to iterate over the widgets using the findChildren method:

for widget in parent_widget.findChildren([QLineEdit, QComboBox]):
    if hasattr(widget, "clear") and callable(widget.clear):
        widget.clear()

或

for widget in parent_widget.findChildren(QWidget):
    if not isinstance(widget, QLabel) and hasattr(widget, "clear") and callable(widget.clear):
        widget.clear()
