Created February 23, 2016 18:59
This functions show how to connect to a signal defined by a QMetaProperty. This is usefull to create editor for an object without knowing the object itself.
QWidget *ProjectWidget::_createBoolTreeEntry(QObject *cloudData, QMetaProperty property)
{
auto checkbox = new QCheckBox(this);
checkbox->setChecked(property.read(cloudData).toBool());
connect(checkbox, &QCheckBox::clicked, [=](bool checked)
{
property.write(cloudData, checked);
});
