我创建了一个小部件，小部件的过程从输入 SQL.table_name 开始，然后切换 Run_analysis 按钮以生成 csv.file 格式的输出。上述过程表现良好。但我坚持在较大的文本框中打印(打印)语句。
class EpiClass:
NR = 0
R = 0
CT = 0
def __init__(self, obj):
self.obj = obj
def epi_calc(self):
"""Function to process EPI formula"""
with open(FN, "w") as FL: #FN object FL
for j in self.obj:
if j[12] is not None and float(j[12]) != 0: #Exclude (Null, 0) values in Cre-j[12]
j12 = float(j[12])
type(j12)
#type(j[12]) #tested
#type(j[35]) #tested
{
Body of statement, assume it add two variable
}
print("Total no of rows affected:", EpiClass.CT)
print("No. of records not analysed:", EpiClass.NR)
print("No. of records analysed:", EpiClass.R)
这里我们转到 PyQt5。
class WinClass(QMainWindow):
"""Main Window"""
def __init__(self):
super().__init__()
self.title = 'EGFR Widget'
self.left = 10
self.top = 10
self.width = 1920
self.height = 1080
self.init_ui()
def init_ui(self):
"""Window Geometry"""
self.setWindowTitle(self.title)
self.setGeometry(self.left, self.top, self.width, self.height)
#label
# Create textbox
self.textbox = QLineEdit(self)
self.textbox.move(20, 20)
self.textbox.resize(280, 40)
# Create a button in the window
self.button = QPushButton('Run Analysis', self)
self.button.move(20, 80)
#Print affected Rows
self.textbox2 = QLineEdit(self)
self.textbox2.move(120, 120)
self.textbox2.resize(880, 140)
# connect button to function on_click
self.button.clicked.connect(self.on_click)
self.show()
@pyqtSlot()
def on_click(self):
"""Button Action function"""
tb_value = str(self.textbox.text())
new_class = Edb(tb_value)
new_class.eclass()
######Im messed up in this step to print that 3 statements in textbox2#############
tb2_value = str(self.textbox2.text(EpiClass.CT))
#tb3_value = str(self.textbox2.text(EpiClass.NR))
#tb4_value = str(self.textbox2.text(EpiClass.R))
if __name__ == '__main__':
APP = QApplication(sys.argv)
ex = WinClass()
sys.exit(APP.exec_())
请建议一个代码来解决打印语句。非常感谢!
最佳答案
您正在尝试使用只读方法text进行写入，您应该使用setText。我会将这些语句保存在某个变量中并从您的小部件访问，但这取决于您。我希望它有帮助。
def on_click(self):
"""Button Action function"""
tb_value = "Total no of rows affected: {}".format(EpiClass.CT)
self.textbox2.setText(tb_value)
