## Method Documentation

__init__ | ( | self, |
|  | Display | display,
|  | long | supportWindow,
|  | QString | wmName,
|  | SIP_PYLIST | properties,
|  | int | screen=-1,
|  | bool | doACtivate=1
| ) |  |  |

__init__ | ( | self, |
|  | Display | display,
|  | SIP_PYLIST | properties,
|  | int | screen=-1,
|  | bool | doActivate=1
| ) |  |  |

This constructor differs from the above one only in the way it accepts the list of supported properties. The properties argument is equivalent to the first element of the properties array in the above constructor, and therefore you cannot read all root window properties using it.

__init__ | ( | self, |
|  | Display | display,
|  | long | properties,
|  | int | screen=-1,
|  | bool | doActivate=1
| ) |  |  |

This constructor differs from the above one only in the way it accepts the list of supported properties. The properties argument is equivalent to the first element of the properties array in the above constructor, and therefore you cannot read all root window properties using it.

Window Managers must call this after creating the NETRootInfo object, and before using any other method in the class. This method sets initial data on the root window and does other post-construction duties.

Clients must also call this after creating the object to do an initial data read/update.
