Property Change Event occurs whenever the properties of a window, layer or other property provider object has changed.

Getting Started

You can have your python script react to all property change events or react to property change events for a particular class.

To have your script react to all property change events, you need to put your python script in your Python directory under a folder called On_Properties_Changed.

To have your script react to a property change event from a particular class, you need to put your script in your Python directory under one of the folders listed below:

Defined Variables

INTViewer will define several variables for use in your script depending on the source of the property change event.

If the script is in the On_Properties_Changed folder, then the following properties will be included:

• eventType: description of event including source name
• source: the object whose properties were changed
• properties: a dictionary containing names of properties changed and their values

If the script is for a property change event coming from a specific source then the following variables will be included:

• window: the window whose properties were changed (variable only included if source is a window)
• layer: the layer whose properties where changed (variable only included if source is a layer)
• object: the object whose properties where changed (variable only in included if source is not a layer or window)
• properties: a dictionary containing names of properties changed and their values
