3dsmax不同版本 pyside qt UI 设置max窗口为父窗口的方法
3dsmax不同版本 pyside qt widget 设置 max 窗口为父窗口的方法
前言:
3dsmax 在 2014 extension 之后开始集成 python 和 pyside,但是在版本2014 extension - 2015 中,当设置 qt ui 的父窗口为 max 主窗口的时候会报错,3dsmax2016 修复了这个bug,2017 和 2018 对 parenting qt widget to max main window 的方式都有所更新,下面来看看每个版本的具体方式。
3dsmax2014 extension - 2015:
下面是报错的代码:(在maxscript listener中运行 python.executefile @"[path]\maxpygui.py",[path]改为文件的所在路径)
# -*- coding: utf-8 -*- """ 在maxscript listener中运行 python.executefile @"[path]\maxpygui.py" [path]改为 maxpygui.py 所在的路径 """ from pyside import qtgui from pyside import shiboken import maxplus class _gcprotector(object): widgets = [] app = qtgui.qapplication.instance() if not app: app = qtgui.qapplication([]) def main(): maxplus.filemanager.reset(true) w = qtgui.qwidget() w.resize(250, 100) w.setwindowtitle('window') _gcprotector.widgets.append(w) main_layout = qtgui.qvboxlayout() label = qtgui.qlineedit() main_layout.addwidget(label) cylinder_btn = qtgui.qpushbutton("test") main_layout.addwidget(cylinder_btn) w.setlayout(main_layout) # 这是会报错的方式 maxwinhwd = maxplus.core.getwindowhandle() parent = shiboken.wrapinstance(long(maxwinhwd), qtgui.qwidget) w.setparent(parent)#报错在这里,如果你的窗口继承了qtgui.qwidget,parent = parent 也会报错,如果想正常运行,请注释这行 """max2016的修正方式 maxplus.attachqwidgettomax(w) """ """不太好的方式 hwnd = w.winid() import ctypes ctypes.pythonapi.pycobject_asvoidptr.restype = ctypes.c_void_p ctypes.pythonapi.pycobject_asvoidptr.argtypes = [ctypes.py_object] int_hwnd = ctypes.pythonapi.pycobject_asvoidptr(hwnd) maxplus.win32_set3dsmaxasparentwindow(int_hwnd) """ w.show() if __name__ == '__main__': main()
注意:如果运行报错syntaxerror: encoding declaration in unicode string (maxpygui.py, line 0),请去掉第一行的 # -*- coding: utf-8 -*-,在命令行中运行不需要指定,下面的代码例子也一样。
很多人建议不要 parenting qt widget to max main window ,不过还是有人尝试了很多方法,autodesk 官方 也给出了 pyqt4 的方式,链接:https://area.autodesk.com/blogs/chris/pyqt-ui-in-3ds-max-2014-extension,我使用的是pyside,所以没有验证过,也有人把这种方式改为 pyside ,有兴趣的可以试试。
一种比较理想的代替方式:
下面是在:https://github.com/alfalfasprossen/qtinwin 上找到的代码,下载后有以下文件:
在这里只关注 maxparenting.py 和 maxparenting_example.py,在maxscript listener中运行 python.executefile @"maxparenting_example.py",这是以owner的方式来实现的,具体描述请看代码里面的注释。
下面附上代码:

其它.py文件有兴趣的可以自己尝试。
3dsmax2016:
在2016中,终于做出了修正,在模块 maxplus 中增加了attachqwidgettomax(),不过这只是一种简单的指定方式,我们还是没办法获得 max main window 的qt对象,没办法以继承 qtgui.qwidget 来指定parent,but, it's not a bid deal。
# -*- coding: utf-8 -*- """ 在maxscript listener中运行 python.executefile @"[path]\maxpygui.py" [path]改为 maxpygui.py 所在的路径 """ from pyside import qtgui from pyside import shiboken import maxplus class _gcprotector(object): widgets = [] app = qtgui.qapplication.instance() if not app: app = qtgui.qapplication([]) def main(): maxplus.filemanager.reset(true) w = qtgui.qwidget() w.resize(250, 100) w.setwindowtitle('window') _gcprotector.widgets.append(w) main_layout = qtgui.qvboxlayout() label = qtgui.qlineedit() main_layout.addwidget(label) cylinder_btn = qtgui.qpushbutton("test") main_layout.addwidget(cylinder_btn) w.setlayout(main_layout) """这是会报错的方式 maxwinhwd = maxplus.core.getwindowhandle() parent = shiboken.wrapinstance(long(maxwinhwd), qtgui.qwidget) w.setparent(parent)#报错在这里,如果你的窗口继承了qtgui.qwidget,parent = parent 也会报错,如果想正常运行,请注释这行 """ #max2016的修正方式 maxplus.attachqwidgettomax(w) """不太好的方式 hwnd = w.winid() import ctypes ctypes.pythonapi.pycobject_asvoidptr.restype = ctypes.c_void_p ctypes.pythonapi.pycobject_asvoidptr.argtypes = [ctypes.py_object] int_hwnd = ctypes.pythonapi.pycobject_asvoidptr(hwnd) maxplus.win32_set3dsmaxasparentwindow(int_hwnd) """ w.show() if __name__ == '__main__': main()
3dsmax2017:
所以,在2017中,为了解决2016的问题,在 maxplus 中增加了getqmaxwindow(),这个方法直接返回 max main window 的 pyside.qtgui.qwidget object:
""" 在maxscript listener中运行 python.executefile @"[path]\maxpygui.py" [path]改为 maxpygui.py 所在的路径 """ from pyside import qtgui from pyside import shiboken import maxplus class _gcprotector(object): widgets = [] app = qtgui.qapplication.instance() if not app: app = qtgui.qapplication([]) def main(): maxplus.filemanager.reset(true) w = qtgui.qwidget() w.resize(250, 100) w.setwindowtitle('window') _gcprotector.widgets.append(w) main_layout = qtgui.qvboxlayout() label = qtgui.qlineedit() main_layout.addwidget(label) cylinder_btn = qtgui.qpushbutton(u"我们") main_layout.addwidget(cylinder_btn) w.setlayout(main_layout) #max2017的改进方式 parent = maxplus.getqmaxwindow() w.setparent(parent)#上面返回的parent直接是pyside.qtgui.qwidget object,可以不通过wrapping,直接设置为父窗口 """这是会报错的方式 maxwinhwd = maxplus.core.getwindowhandle() parent = shiboken.wrapinstance(long(maxwinhwd), qtgui.qwidget) w.setparent(parent)#报错在这里,如果你的窗口继承了qtgui.qwidget,parent = parent 也会报错,如果想正常运行,请注释这行 """ """max2016的修正方式 maxplus.attachqwidgettomax(w) """ """不太好的方式 hwnd = w.winid() import ctypes ctypes.pythonapi.pycobject_asvoidptr.restype = ctypes.c_void_p ctypes.pythonapi.pycobject_asvoidptr.argtypes = [ctypes.py_object] int_hwnd = ctypes.pythonapi.pycobject_asvoidptr(hwnd) maxplus.win32_set3dsmaxasparentwindow(int_hwnd) """ w.show() if __name__ == '__main__': main()
3dsmax2018 (pyside2):
在2018中,去掉了 maxplus 中的getqmaxwindow(),所以没办法直接获得 max main window 的 pyside.qtgui.qwidget object,但是增加了qthelpers 类,里面有静态方法getqmaxmainwindow() 获得 maxmainwindow 的指针,然后我们可以通过传统方式来进行转换:
maxwinhwd = maxplus.qthelpers.getqmaxmainwindow()
parent = shiboken2.wrapinstance(long(maxwinhwd), qtgui.qwidget)
例子代码在这里就不提供了,只是要注意的是2018开始,集成的是pyside2,所以要用shiboken2,而且 shiboken2 是在 pyside2 下的一个模块,所以导入方式为(和maya的不一样):
from pyside2 import shiboken2
