I know,
but  when I click the right button,it will emit the signal:
itemClick(QTreeWidgetItem*,int).

so I don't know who emit the signal itemClick,left button or right
button.and the result is:when I clicked
the left button,the itemClick will be done
and when I clicked the right button,the itemClick also will be done,but I
don't want to call the itemClick when
I clicked the right button!

so how can I distinguish which button has been clicked when the signal
itemClicked be emited?

thank all
