Contex menu appear multiple times

[kubas]

Hey,
i have this issue:

i added contexmenu to qtreewidget

tree.setContextMenuPolicy(ContextMenuPolicy.CustomContextMenu);
tree.customContextMenuRequested.connect(this, "treeMenu(QPoint)");
 
....
 
private void treeMenu(QPoint point)
{
QMenu menu = new QMenu(tree);
 ... add some actions ... 
menu.exec(ui.tree.mapToGlobal(point));
}

tree.setContextMenuPolicy(ContextMenuPolicy.CustomContextMenu);
tree.customContextMenuRequested.connect(this, "treeMenu(QPoint)");

....

private void treeMenu(QPoint point)
{
QMenu menu = new QMenu(tree);
 ... add some actions ... 
menu.exec(ui.tree.mapToGlobal(point));
}

To copy to clipboard, switch view to plain text mode 

it works just fine but ..
if i right click on it it fires up 3 times,
so multiple times is the signal emitted.
How to deal with it and filter the signals or block ?

Greets,
Kubas
