## Description

The GladeWidgetAdaptor object is a proxy for widget class support in Glade. it is automatically generated from the xml and allows you to override its methods in the plugin library for fine grained support on how you load/save widgets and handle thier properties in the runtime and more.

## Functions

### enum GladeCreateReason

These are the reasons your GladePostCreateFunc can be called.

#### Members

GLADE_CREATE_USER | Was created at the user's request (this is a good time to set any properties or add children to the project; like GtkFrame's label for example). |
GLADE_CREATE_COPY | Was created as a result of the copy/paste mechanism, at this point you can count on glade to follow up with properties and children on its own. |
GLADE_CREATE_LOAD | Was created during the load process. |
GLADE_CREATE_REBUILD | Was created as a replacement for another project object; this only happens when the user is changing a property that is marked by the type system as G_PARAM_SPEC_CONSTRUCT_ONLY. |
GLADE_CREATE_REASONS | Never used. |
