如何确保单选按钮处于选中状态
如何确保单选按钮处于选中状态
提问于 2019-06-02 21:33:18
我正在做一个实验，在这个实验中，我向参与者展示刺激，并在每次刺激后问他们问题。我有四个问题，每个问题都在一个单独的框架中。每个问题的答案是从七个单选按钮中选择一个。我在一个单独的框架中也有一个按钮，用于保存选择的值并显示下一个刺激。这里的问题是，如果参与者忘记选择其中一个单选按钮，该按钮的值将保存为0，我希望避免这种情况。我试图设置一个条件，仅当选择了所有单选按钮时才启用下一个刺激按钮，但我失败了。有没有办法做到这一点？

您可以让按钮始终处于活动状态，并在按下它时检查条件，只有在设置了所有变量时才进入下一个刺激：
if all([urgency.get(), annoyance.get()] ... etc):
# go to next stimulus或者，您可以在IntVars和enable按钮中跟踪更改，仅当全部设置完毕后才能跟踪更改。为每个IntVar设置一个跟踪：
urgency.trace('w', enable_button)然后在回调函数中检查IntVar状态：
def enable_button(*args):
if all([urgency.get(), annoyance.get()] ... etc):
