[Question] Crash if Url is incomplete
Unsolved
QtWebEngine
-
Good Evening Forum.
I have the following strange Problem:When the Url contains only Strings like ftp:/, ftp://, http:/, http:// etc, the whole Application crashes. I wrote an very simple if else Checkpoint:
if(errorTestString.endsWith("ftp:/", Qt::CaseInsensitive) || errorTestString.endsWith("ftp://", Qt::CaseInsensitive) || errorTestString.endsWith("ftps:/", Qt::CaseInsensitive) || errorTestString.endsWith("ftps://", Qt::CaseInsensitive) || errorTestString.endsWith("http:/", Qt::CaseInsensitive) || errorTestString.endsWith("http://", Qt::CaseInsensitive) || errorTestString.endsWith("https:/", Qt::CaseInsensitive) || errorTestString.endsWith("https://", Qt::CaseInsensitive)) { // QWebEnginePage::WebAction stopOnError; //stopOnError = QWebEnginePage::Stop; m_BrowserModule->triggerPageAction(QWebEnginePage::Stop, true); //m_BrowserModule->triggerPageAction(QWebEnginePage::Stop); QMessageBox::critical(this, "Invalid Url", "Please check Url"); // m_BrowserModule->triggerPageAction(stopOnError); //m_BrowserModule->load(QUrl("www.google.de")); } else if(!errorTestString.endsWith("ftp:/", Qt::CaseInsensitive) || !errorTestString.endsWith("ftp://", Qt::CaseInsensitive) || !errorTestString.endsWith("ftps:/", Qt::CaseInsensitive) || !errorTestString.endsWith("ftps://", Qt::CaseInsensitive) || !errorTestString.endsWith("http:/", Qt::CaseInsensitive) || !errorTestString.endsWith("http://", Qt::CaseInsensitive) || !errorTestString.endsWith("https:/", Qt::CaseInsensitive) || !errorTestString.endsWith("https://", Qt::CaseInsensitive)) { m_BrowserModule->load(loadEnteredUrl); }The Error Message in Debug Mode is:

[1209/200239:FATAL:navigation_controller_impl.cc(927)] Check failed: active_entry->site_instance() == rfh->GetSiteInstance(). The program has unexpectedly finished.I know, it is unlikely that someone types only i.e. ftp:// but I know that I sometimes accidently hit the Enter Button. So it should not crash the whole Application. That is complete BS. If it is only a String like 'abc', you get the normal ERR_NAME_NOT_RESOLVED Page.
The Problem is, that calling the Stop Trigger to Stop loading the Page/Url, is already too late. The if else Checkpoint gets hit, but the Application crashes after that.
Thanks!
