将用户界面对象从文件调用到另一个文件 [英] Calling UI objects from a file into another

问题描述

我目前正在用Python为Maya编写UI脚本.

I am currently writing a UI script for Maya in Python.

因此，我的UI顶部具有不同的选项卡，并且我不想将每个代码都放在MainClass中，因为这太麻烦且太长了.对于每个选项卡，我想在不同的.py文件中编写其脚本.我想在__init__函数下创建连接，同时，将另一个脚本中的函数加载到要使用的MainClass中.

So, I have UI that has different tabs at the top and I do not want to put every single piece of code in the MainClass because that would be too messy and long. For every tab, I want to write its script in a different .py file. I want to create the connections under the __init__ function, at the same time, load functions from another script into this MainClass to be used.

问题是，我应该如何在新文件中从UI调用objectName?我试图导入MainClass代码，但是没有用，并且我不想在新的.py文件中初始化UI窗口.解决这个问题的好方法是什么?

Question is, how should I go about calling objectName from the UI in a new file? I tried to import the MainClass code but that didn't work and I don't want the initialize the UI window in the new .py file. What's a good way to go about this?

示例:

test.ui文件具有一个标记为打印"的按钮和一个列表小部件.每次按下打印"按钮，列表小部件上都会出现"Hello World"字样.

test.ui file has one button labelled "Print" and a list Widget. Every time 'Print' button is pressed, the words "Hello World" will appear on the list widget.

在loadUi_test.py文件中

In loadUi_test.py file

def loadUi(uiFile):
    #code that loads ui

def getMayaWindow():
    #gets main Maya Window

    ptr = apiUI.MQtUtil.mainWindow()
    if ptr is not None:
        return shiboken.wrapInstance(long(ptr), QtGui.QMainWindow)

class mainClass():
    def __init__(self, parent = getMayaWindow()):

        super(pipeWindow,self).__init__(parent)
        self.setupUi(self)

    def closeEvent(self,event):
        super(mainClass, self).closeEvent(event)

在function_test.py

In function_test.py

def printFunc():
    listWidget.clear()
    listWidget.addItem("Hello World!")

在 init .py

from pipeline import loadUi_test
from pipeline import function_test

uiFile = "test.ui"
b = loadUi_test.loadUi(uiFile)
a = loadUi_test.mainClass()
a.pushButton.clicked.connect(function_test.printFunc(b))

这不起作用，出现错误元组对象没有属性listWidget"

This does not work, I get an error " tuple object has no attribute listWidget "

如果我改为这样做:a.pushButton.clicked.connect(function_test.printFunc(a))，则会收到错误无法连接信号clicked()"

If I do this instead: a.pushButton.clicked.connect(function_test.printFunc(a)), I get the error "Failed to connect signal clicked()"

推荐答案

通常，只要所有文件在python路径上都可用，就可以从其他文件加载类.您可以使用import语句加载类.

In general, you can load classes from other files as long as all of the files are available on your python path. You can load a class using the import statement.

典型模式的基本示例在磁盘上看起来像这样

A basic example of the typical pattern looks like this on disk

mytool
|
+---  __init__.py
+--- model_tab.py
+--- texture_tab.py
+--- tool_tab.py

其中的主要工具是mytool，在__init__.py中定义，而组件则位于其他文件中.您可以使用from SomeModule import SomeClass模式导入类.这样可以很容易地将您的作品保存在单独的文件中.您可以在__init__.py

where the main tool is mytool, defined in the __init__.py and the component pieces live in the other files. You can import a class using the from SomeModule import SomeClass pattern. That makes it easy to keep your pieces in separate files. You'd structure the imports like this in __init__.py

from mytool.model_tab import ModelTab
from mytoool.texture_tab import TextureTab
from mytool.tool_tab import ToolTab

有了这个，您就可以使用在其他文件中定义的类来汇编实际的gui.您可以将主类放在__init__.py中，也可以放在方便的单独文件中

With that in place you can assemble your actual gui using the classes you have defined in your other files. You could put you master class in the __init__.py or in a separate file as seems convenient
