在 QlineEdit PyQT 中设置变量

Question

I need to put a value of an element ( float) of a list into a QlineEdit of GUI i developed with Qt Designer.

raw = self.model_lineEdit.text()  
print('raw : ', raw)
ic,E = zip(*[ list(map(float,line.split(", "))) for line in raw.split("\n") ])
E,ic = np.array(E),np.array(ic)
self.Eoff1_lineEdit.setText(E[3]) 

Unfortunately, it does not work. Can someone help me please ? Thank you in advance and have a good day :) !

Answer 1

Probably it is because you are actually trying to write something different from a string.

To ensure that your data is passed as string, you have to use

self.Eoff1_lineEdit.setText(str(E[3]))

instead of

self.Eoff1_lineEdit.setText(E[3])
