英文:
A button defined as default with the qt designer GUI does not respond to return on Linux/Mac
问题
我正在学习PyQt6。使用Qt Designer创建了一个简单的GUI。请看截图。代码也可以在那里看到。
我想要实现的目标是，我的GUI中的按钮是默认按钮，因此在输入数字后按Enter/Return键会触发转换。
在macOS和Linux下都没有成功。
以下是您的代码部分：
from PyQt6.QtWidgets import QApplication, QWidget
import sys
from PyQt6 import uic
from rechner import Rechner
class UI(QWidget):
def __init__(self):
super().__init__()
uic.loadUi("maingui.ui", self)
self.button.setAutoDefault(True)
self.button.clicked.connect(self.handle_button_click) # 将按钮连接到一个函数
def handle_button_click(self):
rechner = Rechner()
kelvin, fahrenheit = rechner.umrechnung(int(self.eingabe.text()))
self.label_kelvin.setText(str(kelvin) + " K")
self.label_fahrenheit.setText(str(fahrenheit) + " F")
app = QApplication(sys.argv)
window = UI()
window.show()
app.exec()
我已经尝试过autoDefault和default，以及同时使用两者。另外，我在代码中添加了一行self.button.setAutoDefault(True)。不幸的是，按钮未明显显示为默认按钮，并且不像通常情况下那样响应Enter/Return键。
英文:
I am just working my way to PyQt6. Created a simple GUI using Qt Designer. See screenshot. The code can be seen there as well.
What I want to achieve is that the button in my GUI is a default button and thus after entering a number by Enter/Return the conversion is triggered.
Neither under macOS nor under Linux
Hier noch mein Code:
from PyQt6.QtWidgets import QApplication, QWidget
import sys
from PyQt6 import uic
from rechner import Rechner
class UI(QWidget):
def __init__(self):
super().__init__()
uic.loadUi("maingui.ui", self)
self.button.setAutoDefault(True)
self.button.clicked.connect(self.handle_button_click) # connect the button to a function
def handle_button_click(self):
rechner = Rechner()
kelvin, fahrenheit = rechner.umrechnung(int(self.eingabe.text()))
self.label_kelvin.setText(str(kelvin) + " K")
self.label_fahrenheit.setText(str(fahrenheit) + " F")
app = QApplication(sys.argv)
window = UI()
window.show()
app.exec()
I have already tested autoDefault as well as default and both at the same time. Also in the code I added a line self.button.setAutoDefault(True). Unfortunately, the button is not displayed recognizably as a default button and does not respond to Enter/Return as usual.

谢谢您提供的解决方案。

Thank you for the solution.
> If you read the documentation more carefully (especially the default property), you'll see that it specifically refers to dialogs. You're just using a QWidget, which doesn't support such a mechanism. You need to use a QDialog. – musicamante
