Hi to all!

I got an idea how to save settings for a widget, but I do no know how to code it. Here is my problem:

In my app I have several widgets (mostly QWidget) - settings pages under main settings window (also derived from QWidget). Every settings page has QLabels, QTextEdits, QComboboxes, etc ... Now, when I click save, the save slot connected to signal clicked must get contens of all textedits and other value input widgets and save them in a object, which class is subclassed from QSettings. At the end, this app must notify sister parent application that new settings has been apllied to ini file and client must reeread settings without terminating and reruning it. Is this possible?
