Is there a way to get all elements like (input, label , combox) with names and regarding value?

BluTiGeS

Hi all,

i am searching for a way how I can get all Elements on a Widget which has focus.

So for example I have a widget with 2 labels and some boxes, the first label is just for example "NOTE:" and the second would be "some hint",
Also there are some comboboxes and input fields on this widget.

So I am trying to get all element like the labels and the comoboxes with their name and the current set value.

Is this somehow possible in qt? So that i maybe get a text output of the current set input elements ?

So that the result could be:
@
label1 has value "NOTE"
label2 has value "some hint"
comboBox has value 2 selected
@

Many Thanks in advance

Regards

Hi

Well If you make them in designer, you can access all via
ui->

If you new them yourself, you could just keep the pointers around ?

else
look at
QObject::findChildren

Something like

  QList<QWidget*> mylist= parent.findChildren<QWidget*>();
    foreach (const QWidget* current, mylist) {
       
    }

parent being the widget you want to work with.
But can you describe more what you have or show the program so maybe there is a better way.

You can walk through QObject tree:

const QObjectList localChildren = ui->centralWidget->children();
foreach (QObject *obj, localChildren) {
QLabel *label = qobject_cast<QLabel *>(obj);
if(label){
qDebug() << label->text();
}
}

Or do it recursively.

thanks for the replies, i will have a look into it.

So for my use case i think i need to get first the widget which ahsa focus with:

QWidget *focus =  QApplication::focusWidget();

and then use yeckel 's code part

const QObjectList localChildren = focus->children();
foreach (QObject *obj, localChildren) {
QLabel *label = qobject_cast<QLabel *>(obj);
if(label){
qDebug() << label->text();
}
QLabel *box= qobject_cast<QComboBox*>(obj);
if ( box)
{
box->itemData(box->currentIndex());
}
}

is this understanding correct?

@BluTiGeS
Almost correct,
just also make sure the variable is the same type as the one toy try to cast to

QLabel *box= qobject_cast<QComboBox*>(obj);
if ( box)
should be
QComboBox*box= qobject_cast<QComboBox*>(obj);

Thanks, my fault copy paste error ;)

I will give it a try

@BluTiGeS
Can I ask why you need to do it so dynamic?
To avoid to rewrite the code that create the widgets in first place or
you doing something fancy?

BluTiGeS

The background behind this is that i want to have a way to automate testing of the application running.

So therefore i will have commands sending keyevents to the application and then a command to get the current screen values and get the as a XML or something similar, which than can be read by a python script for example to check if all values are set correct after the key sequence.

I am using a pad having 6 input keys (embedded) so not a full keyboard.

Do you have any better idea how to automate it?

Important is that I must be able to to get all information for the currently view on the page on the display device in a readable file format.

Ahh its module testing.
then it makes sense :)

Well there is
http://doc.qt.io/qt-5/qtest-overview.html
Never used it so can say if its good or anything.

I'm using http://funq.readthedocs.org/ for something similar.
