我已经编写了一个Python应用程序,我想分发它。我已经在其之上构建了一个GUI,并且到目前为止运行良好。我使用以下命令来设置GUI:
qtCreatorFile = "gui.ui"
Ui_MainWindow, QtBaseClass = uic.loadUiType(qtCreatorFile)
class MyApp(QtWidgets.QMainWindow, Ui_MainWindow):
def __init__(self):
# Initialize parent PyQt classes
QtWidgets.QMainWindow.__init__(self)
self.setupUi(self)
(....)
应用程序以以下内容开头:
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
window = MyApp()
window.show()
sys.exit(app.exec_())
如果我正确理解,为了将'gui.ui'文件与fbs一起使用,我应该将其作为资源加载。所以我将它们用作修改:
from fbs_runtime.application_context import ApplicationContext, cached_property #added to imports)
class AppContext(ApplicationContext): # Subclass ApplicationContext
def run(self):
qtCreatorFile=self.get_design() # to get the .ui file
Ui_MainWindow, QtBaseClass = uic.loadUiType(qtCreatorFile)
window = MyApp()
version = self.build_settings['version']
window.setWindowTitle("EPANET parser v" + version)
window.show()
return self.app.exec_()
def get_design(self):
qtCreatorFile=self.get_resource("gui.ui") # It is in the correct src\main\resources path
return qtCreatorFile
@cached_property # all tutorials suggest this , but don't understand why. ???
def main_window(self):
return MainWindow(self)
fbs应用程序应以以下if __name__ == '__main__:'
替换开头:
if __name__ == '__main__':
appctxt = AppContext()
exit_code = appctxt.app.exec_()
sys.exit(exit_code)
但是,出现以下错误:
Traceback (most recent call last):
File "C:\Users\....src\main\python\main.py", line 61, in <module>
class MyApp(QtWidgets.QMainWindow, Ui_MainWindow):
NameError: name 'Ui_MainWindow' is not defined
我了解到MyApp现在是从Ui_MainWindow
类内部定义的AppContext
继承的,MyApp无法引用它。任何帮助将不胜感激!
答案 0 :(得分:3)
您可以使用uic.loadUi()代替uic.loadUiType(),只需通过传递.ui路径即可填充窗口
main.py
from fbs_runtime.application_context.PyQt5 import ApplicationContext, cached_property
import sys
from mainwindow import MyApp
class AppContext(ApplicationContext):
def run(self):
self.window.resize(640, 480)
self.window.show()
return appctxt.app.exec_()
def get_design(self):
qtCreatorFile = self.get_resource("gui.ui")
return qtCreatorFile
@cached_property
def window(self):
return MyApp(self.get_design())
if __name__ == "__main__":
appctxt = AppContext()
exit_code = appctxt.run()
sys.exit(exit_code)
mainwindow.py
from PyQt5 import QtWidgets, uic
class MyApp(QtWidgets.QMainWindow):
def __init__(self, ui, parent=None):
super().__init__(parent)
uic.loadUi(ui, self)
