Is it possiable to get Qlabel name from Qlabel text? : Our project, We have used Qlabels in different UI and different class.

like. 

ui->label->setText(label_ABC);

we want to provide label name change access to the user. 

default name already exists. if the user wants to change label name then first they change label_ABC to label_XYZ. this is saved in a database. 

we want to replace lable_ABC to label_XYZ in all UI.

what is the best way to doing this?
