[Solved] QToolButton Dynamic translation

[Osper]

Hi everyone!

I am writing a QT C++ application which uses a dynamic translation. It works fine with QPushButton, but it crashes when I try to dynamically translate QToolButton.
Could anyone point me in the right direction to solve this problem?

Declaration (mainwindow.hpp):

#include <QMainWindow>
 
class QStackedWidget;
class QPushButton;
class QToolButton;
 
class MainWindow : public QMainWindow {
	Q_OBJECT
 
public:
	explicit MainWindow(QMainWindow *parent = 0);
 
public slots:
 
private slots:
	void setLangEn();
	void setLangSl();
 
private:
	void closeEvent(QCloseEvent *event);
	void changeEvent(QEvent *event);
 
	QPushButton *cancelBtn;
 
	QToolButton *btnTParcelTake;
 
};

#include <QMainWindow>

class QStackedWidget;
class QPushButton;
class QToolButton;

class MainWindow : public QMainWindow {
	Q_OBJECT

public:
	explicit MainWindow(QMainWindow *parent = 0);
	
public slots:
	
private slots:
	void setLangEn();
	void setLangSl();

private:
	void closeEvent(QCloseEvent *event);
	void changeEvent(QEvent *event);
	
	QPushButton *cancelBtn;
	
	QToolButton *btnTParcelTake;

};

	sm->setMapping(btnTParcelTake, 1);
 
	...
}
 
void MainWindow::setLangEn() {
	qApp->removeTranslator(&appTranslator);
	if (appTranslator.load("rc/translations/translation_en.qm", ".")) {

	if (event->type() == QEvent::LanguageChange) {
		setWindowTitle(tr("Translated"));
		cancelBtn->setText(tr("Cancel"));
		btnTParcelTake->setText(tr("Take Package"));  //<<= program crashes when I use this command
	}

Ok, I have managed to solve this by changing QToolButton *btnTParcelTake = new QToolButton(); to btnTParcelTake = new QToolButton();
