Add Data with a QPushButton to QTreeView

[Tortura]

Hi,

I have two QTreeViews. The first one is filled with Data. Now I want to select data from this view and add it by clicking on a QPushButton to a second QTreeView.

I know that I have to connect the QPushButton to a method that is adding the data. My problem is that I don't know how the method should look like.

Thanks for help.

Simply connect your pusshButton to the slot:
@
....
connect(this->btn_copy, SIGNAL(clicked()), this, SLOT(copy_clicked()));
...
@

in this slot just copy item from one treeview to another:
@
void YourClass::copy_clicked()
{
this->tree_view_right->addItem(this->tree_view_left->itemAt(this->tree_vew_left->currentIndex()));
}
@

Thanks for your reply.

I connected my button and wrote the copy_clicked() method but when I start my program I get this error:

Object::connect: No such slot MyClass::copy_clicked()
Object::connect: (sender name: 'btn_copy')
Object::connect: (receiver name: 'Dialog')

What did I do wrong?

Weird, I placed the method in front of the connect command and the errors don't appear anymore. BUT nothing else is happening.

have you declared your slot in class declaration? Like:
@
private slots:
void copy_clicked();
@

Have you read about signals and slots already? "Signals and slots":http://doc.qt.digia.com/qt/signalsandslots.html

I'm a beginner with Qt and programming with Python and PyQt. Therefore it's a bit complicated to rethink the c++ code in python and how to do everything right.

Because I became desperate with this problem I posted it here and thought that I can solve this problem. I'll read the "Signals and slots" article. Thanks.

I tried something else. And now by starting the program it says

'QTreeView' object has no attribute addItem

Do I have to implement the addItem() method by myself?

[AcerExtensa]

Yes, addItem was just from my head... use right method to insert element to the treeview...

[AcerExtensa]

If you use QTreeWidget instead of QTreeView this method will already exist... (addItem, insertItem, etc...)
