get mousePressEvent in qlistview

[saber]

@mrjj here is how i tried

// in constructor 
connect(ui->viewlist->viewport(), SIGNAL(clicked()),this, SLOT(ll()));

void corefm::ll(){

    qDebug() << "lllllll " ;
}

in application output i got this .

QObject::connect: No such signal QWidget::clicked() in
../corebox/corefm/corefm.cpp:45
QObject::connect:  (sender name:   'qt_scrollarea_viewport')
QObject::connect:  (receiver name: 'corefm')

and why this is not working ??

void corefm::mousePressEvent(QMouseEvent *event)
{
    qDebug() << "Mounting " ;
}

Hi
The viewport do not have a clicked() signal.
I meant for you use it with event filter to catch it that way.

@mrjj

here is the 2 view for my file manager . first on is listview and second one is tree view.
but mouse mousePressEvent is not working.

here is the cpp file corefm.cpp

ui->viewlist->viewport()->installEventFilter(this);
ui->viewtree->viewport()->installEventFilter(this);

@mrjj i am getting mousePressEvent in outside of listview

[mrjj]

Hmm, it dont recall it being that difficult.
And the listview is all the way down there ?

[saber]

@mrjj
no, that is another widget.
i need that function . please help me

[mrjj]

@saber
Well what ever widget is under the mouse cursor gets the click.
So you need event filter on those too.
I though you just want to click outside the actual items,
not the whole wide window.

@mrjj
yes , i just want to click outside the actual items in listview .
i just want click event on list view .
not whole window.

but mouse press event not working there.

[saber]

Try this:

class ClickOutListView : public QListView{
Q_OBJECT
Q_DISABLE_COPY(ClickOutListView)
public:
explicit ClickOutListView(QWidget* parent = Q_NULLPTR) : QListView(parent){}
Q_SIGNALS:
void clickedOut();
protected:
void mousePressEvent(QMouseEvent *event){
if(!indexAt(event->pos()).isValid()) 
clickedOut();
QListView::mousePressEvent(event);
}
};

and right-click->promote your QListView to ClickOutListView in designer

@VRonin
sorry for late reply .
your code is working.
can i use this in treewidget to achieve same mouseevent?

[mrjj]

@saber
Hi
Yes QTreeWidget also have
mousePressEvent etc. so should work the same.
