How to disable individual members of a QHash and QList?

[in_dbasu]

In my project i have a widget which have a QHash vector table and QList on it.I want to access each individual members of the QHash and QList and then disable the members.But i don't get any function to disable the members.

Code:

for(index=0;index<screen.children.count;index++)
{
 
screen.children.at(index).?
 
}

for(index=0;index<screen.children.count;index++)
{

screen.children.at(index).?

}

To copy to clipboard, switch view to plain text mode 

Here screen is a QWidget. In Qwidget class we have a function called setdisabled which can be used to disable the whole widget but how to disable the individual members?
