如何在PyQt5中对齐QLabel?

self.blank_word_label = QLabel(blank_word, self)
self.blank_word_label.move(20,200)
#This doesn't work!!!
self.blank_word_label.setAlignment(Qt.AlignCenter)
#Sets where on the screen the window will open and the size of the window respectively using x and y coordinates
self.setGeometry(1427, 30, 162, 231)
#Locks the size of the window and make it impossible for the user to change it
self.setFixedSize(self.size())

这是一个hang子手游戏项目,我正在使用Windows 7机器上的PyQt5和Python。我已经使用相同的设置创建了两个小项目(一个硬币翻转模拟器和一个模具卷模拟器)。我仍然是初学者,这是我第三次和最近的“重大”项目。我无法将单词的空白版本与主窗口的中心对齐,以至于无法弄清楚。欢迎任何帮助/建议。 :)如何在PyQt5中对齐QLabel?
答
我认为你遇到的问题是你没有给你的标签明确的宽度,因此它只是使用它需要的任何空间。我将设置标签宽度的主窗口部件的宽度,然后将它只有垂直,即:
self.blank_word_label = QLabel(blank_word, self)
self.blank_word_label.setFixedWidth(162)
# Or, if you reorder your code so that your self.setGeometry(1427, ...) line occurs before this code, you could do directly:
# self.blank_word_label.setFixedWidth(self.width())
self.blank_word_label.move(0, 200)
self.blank_word_label.setAlignment(Qt.AlignCenter)
另外,我想你可以让标签可以自动调整大小,然后调整基于其宽度和其左父宽度。无论如何,为了使其居中,您应该始终确保 label.width() + 2 * label.left() == form.width()
。即使label.left()为负值,label.width()由于某种原因高于form.width(),这应该可以工作。

非常感谢。这似乎解决了这个问题。对不起,我无法赞成,因为我没有足够的声誉,但这对我有效。再次感谢。 :) –
对于您指的是哪种QLabel,如果文本的几何尺寸较小,也可以将文本居中。 – eyllanesc

@eyllanesc我想将用户猜测的单词的空白版本与窗口中心对齐,因为所有单词都有不同的长度。 –
