将用 Qt 设计器创建的 .ui 文件传递给 fbs 进行打包 [英] Pass a .ui file created with Qt designer to fbs for packaging
问题描述
我编写了一个 Python 应用程序，我想分发它.我已经在它上面构建了一个 GUI，到目前为止工作正常.我使用以下内容来设置 GUI:
i have written a Python application and I would like to distribute it. I have built a GUI on top of it and works fine so far. I use the following to set up the 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:
The application starts with the following:
if __name__ == "__main__":
app = QtWidgets.QApplication(sys.argv)
window = MyApp()
window.show()
sys.exit(app.exec_())
如果我理解正确，对于使用 fbs 打包的 'gui.ui' 文件，我应该将其作为资源加载.所以我使用这些作为修改:
If I understand correctly, for using the 'gui.ui' file withing packaging with fbs, I should load it as a resource. So I use these as a modification:
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 应用程序应该以如下替换 if __name__ == '__main__:':
The fbs application should start with the following replacement of if __name__ == '__main__:':
if __name__ == '__main__':
appctxt = AppContext()
exit_code = appctxt.app.exec_()
sys.exit(exit_code)
但是，我收到以下错误:回溯(最近一次调用最后一次):文件C:\Users\....src\main\python\main.py"，第 61 行，在 <module> 中类 MyApp(QtWidgets.QMainWindow, Ui_MainWindow):NameError: name 'Ui_MainWindow' 未定义
However, I get the following error:
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
我知道 MyApp 现在继承自 AppContext 类中定义的 Ui_MainWindow，MyApp 无法引用它.任何帮助将不胜感激！
I understand that the MyApp is inheriting from the Ui_MainWindow that is defined inside the AppContext class now, and MyApp cannot reference it. Any help will be greatly appreciated!
推荐答案
您可以使用 uic.loadUi() 代替 uic.loadUiType()，它只是通过传递 .ui 路径来填充窗口
Instead of using uic.loadUiType() you can use uic.loadUi() that just populates the window by passing the .ui path
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)
