Hello,
if I loose a connection to device I want to open a message box which says that the application waits for the connection to be reestablished.
Therefore, when i recognize the lost connection i start a thread which will run until the connection is established again. Then it emits a Signal which says that the connection is established.
This signal is connected to a slot of my gui thread, but unfortunately it does not close the messagebox, cause the thread is stuck in showing the messagebox.
Is there a proper way to do this? Here is a snippet of my code
QMessageBox* m_box; //private class variable of gui thread
public void on_ConnectionLost() {
m_box = new QMessageBox();
m_box->setText("Wait for connection to return");
m_box->show();
}
public void on_ConnectionEstablished() {
if (m_box != nullptr) {
m_box->close();
delete m_box;
m_box = nullptr;
}
//restart processing
}
Thank you!
Regards
