python for houdini——pyside2&pyqt5在houdini中的使用
houdini虽然可以创建ui界面,但是都是通过代码所实现的，而外置qt插件可以创建图形界面，然后在代码中加载，即可以实现所见即所得的界面，再导入houdini中
具体步骤如下：
1、下载python，然后安装pyside2或pyqt5组件
通过命令行 pip install PySide2 或 pip install PyQt5 即可完成安装
2、在python安装路径找到designer，打开创建界面，之后保存为ui文件
3、生成py文件
通过命令行
pyuic5 -o C:\Users\Administrator\Desktop\text1.py C:\Users\Administrator\Desktop\text1.ui
生成py文件
打开py文件
# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'C:\Users\Administrator\Desktop\text1.ui'
#
# Created by: PyQt5 UI code generator 5.13.1
#
# WARNING! All changes made in this file will be lost!
from PyQt5 import QtCore, QtGui, QtWidgets
class Ui_Form(object):
def setupUi(self, Form):
Form.setObjectName("Form")
Form.resize(400, 300)
self.gridLayout = QtWidgets.QGridLayout(Form)
self.gridLayout.setObjectName("gridLayout")
self.pushButton = QtWidgets.QPushButton(Form)
self.pushButton.setObjectName("pushButton")
self.gridLayout.addWidget(self.pushButton, 0, 0, 1, 1)
self.pushButton_2 = QtWidgets.QPushButton(Form)
self.pushButton_2.setObjectName("pushButton_2")
self.gridLayout.addWidget(self.pushButton_2, 1, 0, 1, 1)
self.pushButton_3 = QtWidgets.QPushButton(Form)
self.pushButton_3.setObjectName("pushButton_3")
self.gridLayout.addWidget(self.pushButton_3, 2, 0, 1, 1)
self.retranslateUi(Form)
QtCore.QMetaObject.connectSlotsByName(Form)
def retranslateUi(self, Form):
_translate = QtCore.QCoreApplication.translate
Form.setWindowTitle(_translate("Form", "Form"))
self.pushButton.setText(_translate("Form", "PushButton"))
self.pushButton_2.setText(_translate("Form", "PushButton"))
self.pushButton_3.setText(_translate("Form", "PushButton"))
可以看出这是一个创建ui界面的类，在setupUi函数内创建界面，然后在restranslateUi函数中修改界面
修改py文件里面的代码

self.pushButton_3.setText(_translate("Form", "PushButton"))
class MyWidget(Ui_Form,QtWidgets.QWidget):
def __init__(self,parent=None):
super(MyWidget,self).__init__(parent)
self.setupUi(self)
if __name__ == '__main__':
app = QtWidgets.QApplication(sys.argv)
win = MyWidget()
win.show()
sys.exit(app.exec_())
在命令行里运行py文件
python C:\Users\Administrator\Desktop\text1.py
得到界面程序
4、修改py文件，导入到houdini中
注释掉刚才的修改

将文件保存到E:/360MoveData/Users/Administrator/Documents/houdini17.0/python2.7libs
在houdini工具栏新建一个工具，写入代码
from text1 import Ui_Form
from PySide2 import QtWidgets
class MyWidget(Ui_Form,QtWidgets.QWidget):
def __init__(self,parent=None):
super(MyWidget,self).__init__(parent)
self.setupUi(self)
widget = MyWidget()
widget.show()
应用，点击该工具，弹出界面
