Hi,
I have derived a class out of Glib::Object and I'm using Glib::Property in
it. I'm able to get the properties to work except for figuring out one
thing.
Some of the properties are required to be read-only while others can allow
read/write access. The read-only properties are initialized like below.
m_propA(*this,
"p0904",
"<some nick name>",
"<some property description",
Glib::PARAM_READABLE)
My understanding was that, irrespective of whether a property is read-only
or read/write, the object that installs the property (including its derived
classes) can both read as well as write. However for other classes (which
only have access to an instance of this object) can only read from it. I
wrote a little test code to confirm this theory but to my surprise everyone
had read/write access!
What could I be doing wrong?
Also is there any means where if any of the properties of an object is
modified, the object gets 'notified'? I found the statement below in *GObject
Reference Manual* (
https://developer.gnome.org/gobject/stable/gobject-properties.html).
*Once the property has been set by the object's set_property class method,
execution returns to g_object_set_property which makes sure that the
"notify" signal is emitted on the object's instance with the changed
property as parameter unless notifications were frozen by
g_object_freeze_notify. *
However I couldn't see any in Glib::Object documentation. Please suggest.
