关闭窗口的窗体qgis
关闭窗口的窗体qgis
提问于 2018-10-03 21:52:49
我正在使用qt designer和一些python代码为QGIS3制作自定义表单，以进行验证。
但是，我在映射按钮动作OK和Cancel时遇到了问题。我首先断开按钮的连接，然后将它们连接到另一个函数以验证表单中的数据。
但是，当我尝试调用close函数(关闭窗口的窗体)时，它只会使窗体消失，但窗口仍然存在
下面是我的代码：
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import QLineEdit, QDialogButtonBox, QComboBox, QLabel, QPushButton
import psycopg2
myDialog = None
cbb_implant = None
Validat = 0
def formOpen(dialog,layerid,featureid):
bdd = psycopg2.connect("host=localhost")
cursor = bdd.cursor()
global myDialog
myDialog = dialog
dialog.hideButtonBox()
global cbb_implant
cbb_implant = dialog.findChild(QComboBox, "cbb_implantation")
cursor.execute('SELECT * FROM l_implantation_type')
fetch = cursor.fetchall()
if len(fetch)>0:
for i in range(0,len(fetch)) :
cbb_implant.addItem(fetch[i][1])
cbb_implant.setCurrentIndex(7)
ok_chem = dialog.findChild(QPushButton, "ok_chem")
ok_chem.clicked.connect(validate)
def validate():
global Validat
if Validat == 0 :
print("HELLO")
Validat = 1
else :
myDialog.save()
myDialog.close()谢谢你的帮助

我发现了另一种关闭整个窗户的方法。
我简单地模拟了退出键按下(通过使用pyautogui模块)，它完成了这项工作。

你可以试试这段代码
myDialog.parent().close()这对我很管用
