这是我的主文件（bazapodataka.py），其中所有其他.ui文件都将被调用

Question

我设法将我的main_GUI文件导入到我的main.py文件中，但我想要实现另一个GUI，该GUI会显示单击按钮的结果main_GUI文件。这可能吗？

这是我的主文件（bazapodataka.py），其中所有其他.ui文件都将被调用

        self.ui = uic.loadUi("C:\Python34\Lib\site-packages\PyQt4\BazaPodataka\database_GUI.ui")
        self.ui.show()

ok = db.open()

if ok:
    print("Connected to database")
else:
    print("Error connecting to database")

sys.exit(app.exec_())

这是我的main_GUI文件（database_GUI.ui）

基本上，我设法将database_GUI.ui文件实现到我的bazapodataka.py文件中，但现在我想打开我的第二个GUI文件（kirurg_GUI.ui），我从"kirurg"选择了comboBox选项，然后点击Add。那可能吗？

编辑：在bazapodataka.py中导入时，我的database_GUI.ui类是否会转发所有按钮，组合框等？

另外，这是最好的方法吗？我的意思是，将外部GUI实现到一个主要的python文件？

编辑2：

import sys
from PyQt4.QtSql import *
from PyQt4 import QtCore, QtGui, uic
from database_GUI import Ui_Main_GUI_Widget
from kirurg_GUI import Ui_kirurg_Widget

class database_GUI(QtGui.QWidget, Ui_Main_GUI_Widget):
       def __init__(self):
              QtGui.QWidget.__init__(self)
              self.setupUi(self)

              button = QtGui.QPushButton("Add_button")
              button.clicked.connect(self.open_kirurg_ui)

       def open_kirurg_ui(self):
              kirurg = KirurgUi()
              kirurg.show()

class kirurg_GUI(QtGui.QWidget, Ui_kirurg_Widget):
        def __init__(self):

db.setDatabaseName("BP Za bolnicu")

db.setPort(5432)
ok = db.open()

if ok:
    print("Connected to database")
else:
    print("Error connecting to database")

sys.exit(app.exec_())

出于某种原因，它不会连接到我的数据库，除非在此之后放入该数据库代码：

if __name__ == "__main__":
           app = QtGui.QApplication(sys.argv)
           main_GUI = database_GUI()
           main_GUI.show()

Answer 1

是的，当然有可能，但我会考虑进行一些重构。

假设您有三个文件：

bazapodataka.py - 这是将加载所有UI的主要python文件
database_ui.py - 这是您的第一个用户界面
kirurg_ui.py - 在第一个用户界面中点击按钮时调用的用户界面

您的bazapodataka.py应该是这样的：

import sys
from PyQt4.QtSql import *
from PyQt4 import QtCore, QtGui, uic
from database_ui import Ui_Main_Gui_Widget #importing UI as py files generated by pyuic
from kirurg_ui import Ui_kirurg_Widget

class TestApp(QtGui.QWidget, Ui_Main_Gui_Widget): #inherit from Ui_Main_Gui_Widget
    def __init__(self):
        QtGui.QWidget.__init__(self)
        self.setupUi() #call the Ui_Main_Gui_Widget's setupUi method

        self.kirurg_Add_button.clicked.connect(self.open_kirurg_ui)

    def open_kirurg_ui(self):
        if self.Add_comboBox.currentText() == "kirurg":
            kirurg = KirurgUi()
            kirurg.exec_()


class KirurgUi(QtGui.QWidget, Ui_kirurg_Widget):
    def __init__(self):
        QtGui.QWidget.__init__(self)
        self.setupUi()


db = QSqlDatabase.addDatabase("QPSQL")
db.setHostName("localhost")
db.setDatabaseName("BP Za bolnicu")
db.setUserName("postgres")
db.setPassword("zanoktica")
db.setPort(5432)
ok = db.open()
if ok:
    print("Connected to database")
else:
    print("Error connecting to database")

if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    win = TestApp()
    win.show()
    sys.exit(app.exec_())

注意：我没有测试应用程序，但应该可以使用。

将多个.ui文件导入main.py文件

这是我的主文件（bazapodataka.py），其中所有其他.ui文件都将被调用

这是我的main_GUI文件（database_GUI.ui）

和我的最后一个gui文件（kirurg_GUI.ui）
