在 PyQT GUI 中循环更新标签 [英] Loop to Update Labels in PyQT GUI

问题描述

我有一个 pyqt gui，其中包含在 init 上填充数据的标签.标签本身很容易更新:

I have a pyqt gui that among other things, has labels that are populated with data on init. The labels themselves are easy to update with:

self.ui.mylabel_1.setText('foobar')
self.ui.mylabel_2.setText('foobar')

有什么办法可以像我下面的伪代码那样以类似的方式循环遍历这个:

Is there any way I can loop over this in a similar way to do this as in my following pseudo:

for num in range (1,24):
   self.ui.mylabel_num.setTest('foobar')

推荐答案

做到这一点的简洁方法是将所有标签的列表存储在某处，即 self.all_labels = [self.ui.mylabel_1, self.ui.mylabel_2] 然后为 self.all_labels 中的标签做 : label.setTest('foobar').

The clean way to do this is to store a list of all your labels somewhere, i.e. self.all_labels = [self.ui.mylabel_1, self.ui.mylabel_2] and then doing for label in self.all_labels: label.setTest('foobar').

您也可以使用 getattr使您的示例工作:

You could also use getattr to make your example work:

for num in range (1,24):
   label = getattr(self.ui, 'mylabel_{}'.format(num))
   label.setTest('foobar')
