Qlistwidget with checkbox

Dear all,

in Qlistwidget i implemented the checkboxes with items,
if i click the item it want to enable the checkbox,
if checkbox already enable it want to disable the checkbod

[i.e] i dont want to click particularly check box to enable, if i click
the item in the Qlistwidget item that item automatically enables the checkbox
and if checkbox already enabled it want to disable?

is it possible? any one have idea about this?

and

is there any possible way to put the check box at right side of the Qlistwidget
