How to Use MEL or Python to auto Open Preference Window and change the setting inside it?

怎样可以使用MEL 或 Python来快速打开Preference窗口，并修改里面的东西？

I need to change the preference setting very very often: 我需要频繁的点击：

Windows>Setting and Preferences>preferences>Display>View>里的Wireframe on Shaded，to paint用来绘制Vertex Color, When i am paint the vertex color,画的时候，I want the green selected Wireframe line disappear, so I change the Wireframe on Shaded to "None"我想让绿色的Wireframe消失，and after that I change it to "Full.

Is there any MEL or Python Language to change this option in one time? And Thankyou~!

有没有MEL 或 Python脚本，可以一键修改这个设置的方法？感谢！！

或者有可以写在Runtime Command Editor里的就更好了。

It will be better if It can be make to a HotKey as well.

Thankyou!!

Hi,

You can use the script editor to find out what underlying commands are being called when you change a UI value. Just 1) open the Preferences window and navigate to the Display settings 2) in the Script editor toggle on History > Echo All Commands 3) Toggle the preference off/on 4) Disable History > Echo All Commands.

Now look at the script editor history pane and you will see these commands.

displayPref -wsa "none";
displayPref -wsa "full";

So, with this knowledge, it is simple to make a script that will toggle this preference without opening the preferences window.

// Toggle wireframeOnShadedActive (-wsa) display preference
displayPref -wsa (`displayPref -q -wsa` == "none" ? "full" : "none");
