Tolong bantu saya mengubah suai pelbagai benang atau berikan beberapa bukti, saya hanya mahu dia mengeluarkan log ke dalam kotak teks. . .

Answer 1

def hanshu(b) Bukankah ini salah? Bolehkah saya memetik self.xxx di sini? Anda boleh menghantar nilai dalam bentuk def hanshu(xx,yy,b) dan kemudian cuba lagi apabila menggunakannya, ia adalah hanshu(self.xx,self.yy,b) Adakah anda faham apa yang saya maksudkan?

Answer 2

Gesaannya sangat jelas
Benang bukan GUI boleh mengendalikan elemen benang GUI
Ini tidak selamat untuk benang dalam QT
Jika anda mahukan benang bukan GUI mengendalikan benang GUI, anda harus menggunakan slot isyarat
