i have a question about the QUiLoader. I load an ui-file with quiloader.load(&file). The ui-file contains some customwidget. The setters from my customwidgets are always called twice. I wondering if i do something wrong or is it a bug?

My problem is, that i have a setter that does slightly more complex things and i dont want to work with flags in the setter like "if(notAlreadyDone){...}". Any ideas how i can avoid that?

Pseudocode:
.h-File
@
class QDESIGNER_WIDGET_EXPORT MyLineEdit : public QWidget{
Q_OBJECT
Q_PROPERTY(QString labelText READ getLabelText WRITE setLabelText)
private:
QString labelText;
public:
void setLabelText(const QString& labelText);
};
@

cpp-File:
@
MyLineEdit::MyLineEdit(QWidget* parent) : QWidget(parent){}

void MyLineEdit::setLabelText(const QString& labelText){
qDebug() << PRETTY_FUNCTION << "LabelText:" << labelText;
this->labelText = labelText;
}
@

Load-UI-File:
@
qDebug() << "--> before" << uiMaskFileName;
QUiLoader loader;
QWidget* parent = new QWidget();
QWidget* formWidget = loader.load(&file, parent);
qDebug() << "--> after";
@

UI-File:
@
...
<item>
<widget class="MyLineEdit" name="myLineEdit">
<property name="labelText">
<string>Test:</string>
</property>
</widget>
</item>
...
@

Consolen-output:
@
--> before "/tmp/my.ui"
void MyLineEdit::setLabelText(const QString&) LabelText: "Test:"
void MyLineEdit::setLabelText(const QString&) LabelText: "Test:"
--> after
