Calculation stops when using QMessageBox -> critical()
-
Hello,
in my programm I use a QMessageBox to display an Error (when closing the application while (Real-Time- ) calculation runs).
Now I have the problem, that the calculation stops until the QMessageBox is closed.This is my code:
@if (this->communicate) {
QMessageBox messageBox;
messageBox.critical(0, "Warning", "Still communicating!");
messageBox.setFixedSize(500, 200);
event->ignore();
}@Is there a way to let my Programm continue its calculation while the QMessageBox is open?
Greetings,

Hi and welcome to devnet,
You have to setup the message box completely yourself and call either show or open for that.
critical() is a static function calling exec thus the blocking behavior (and you are using it wrong)
