[SOLVED] Can’t connect to doubleclick signal in treeview.

scumpyt

First, I apologize for not formatting my code correctly.

Second, I have solved the issue: I included variable names in my SIGNAL/SLOT declaration, which of course need to be removed, then all works fine.

@connect(ui.treeView, SIGNAL(doubleClicked(const QModelIndex& )),
this, SLOT(onShowCenteredBookMark(const QModelIndex&))); // Variable names removed@

Hi,

I have a dock-able widget with a treeView in it. The tree contains book-marked locations to the central map in my app. I would like to be able to double-click on the items in the tree, and then jump to that location on the map. The problem is that I can't seem to get my connect to recognize the signal.

Here is the set-up code in my dockwidget constructor:

@
// Configure treeView...
ui.treeView->setModel(PC->myBookMarkModel);
ui.treeView->setHeaderHidden(false);
ui.treeView->setSortingEnabled(true);
ui.treeView->setSelectionMode( QAbstractItemView::SingleSelection );
ui.treeView->setExpandsOnDoubleClick(false); // Turn off double-click for expand.
ui.treeView->setEditTriggers(QAbstractItemView::NoEditTriggers); // Turn off double-click for edit

// Connect to a slot that will return the view to the bookMarked spot...
connect(ui.treeView, SIGNAL(doubleClicked(const QModelIndex& index)),
this, SLOT(onShowCenteredBookMark(const QModelIndex& index)));
@

It compiles fine, but when I run it, I get this message saying that there is no such signal... What am I doing wrong?
@
Object::connect: No such signal QTreeView::doubleClicked(const QModelIndex& index) in c:\workspace\nextgen\projects\bsoko\source\bookmarkdockwidget.cpp:84
Object::connect: (sender name: 'treeView')
Object::connect: (receiver name: 'BookMarkDockWidget')
@
Anybody have an ideas?
