Translations for tool tips don't show up

[magicp7]

Hello,

I'm relatively new to Qt and I'm having some problems with the translations of my tool tips into other languages.
I've written a method that sets the tool tips on start up. Afterwards I'm loading my .qm file with the translations
and set up the translator. This works fine for everything that isn't a tooltip; all texts are translated, only the tool tips
are shown in the original language.
The tool tip texts are also contained in the .ts file, a translation is available, but it just doesn't use the translation when
I change the language.

Does anyone have an idea what could be causing this?

I added a part of the of the method that sets my tool tips. All my tool tips are set in this way.

void MainWindow::InitToolTips(void) // Set Tool-tips
{
  const QString TStart = "<b><span style=\"color:green;\">";
  const QString TEnd   = "</span></b>";
 
  ui->btn_StartTab->setToolTip(TStart +                     tr("Kopieren von Einstellungen zwischen Drehmomentschlüssel und Datenbank")     + TEnd);
  ui->btn_WrenchTab->setToolTip(TStart +                    tr("Einstellungen für aktuell angeschlossenen Drehmomentschlüssel")             + TEnd);
  ui->btn_ProgramsTab->setToolTip(TStart +                  tr("Schraubfälle und Ablaufpläne verwalten")                                    + TEnd);
  ui->btn_DataTab->setToolTip(TStart +                      tr("In die Datenbank geladene Verschraubungsdaten verwalten")                   + TEnd);
  ui->btn_Workflows->setToolTip(TStart +                    tr("Einstellen von Premium-Workflows")                                          + TEnd);
  ui->btn_LiveMode->setToolTip(TStart +                     tr("Live-Anzeige aktivieren")                                                   + TEnd);
  ui->tbtn_ProgramSettings->setToolTip(TStart +             tr("Zeige den Dialog zur Programmkonfiguration")                                + TEnd);
  ui->tbtn_RadioConfig->setToolTip(TStart +                 tr("Zeige den Dialog zur Funkschnittstelle")                                    + TEnd);
  ui->tbtn_Help->setToolTip(TStart +                        tr("Zeige die Programmhilfedatei an")                                           + TEnd);
}

void MainWindow::InitToolTips(void) // Set Tool-tips
{
  const QString TStart = "<b><span style=\"color:green;\">";
  const QString TEnd   = "</span></b>";
  
  ui->btn_StartTab->setToolTip(TStart +                     tr("Kopieren von Einstellungen zwischen Drehmomentschlüssel und Datenbank")     + TEnd);
  ui->btn_WrenchTab->setToolTip(TStart +                    tr("Einstellungen für aktuell angeschlossenen Drehmomentschlüssel")             + TEnd);
  ui->btn_ProgramsTab->setToolTip(TStart +                  tr("Schraubfälle und Ablaufpläne verwalten")                                    + TEnd);
  ui->btn_DataTab->setToolTip(TStart +                      tr("In die Datenbank geladene Verschraubungsdaten verwalten")                   + TEnd);

  ui->btn_LiveMode->setToolTip(TStart +                     tr("Live-Anzeige aktivieren")                                                   + TEnd);
  ui->tbtn_ProgramSettings->setToolTip(TStart +             tr("Zeige den Dialog zur Programmkonfiguration")                                + TEnd);
  ui->tbtn_RadioConfig->setToolTip(TStart +                 tr("Zeige den Dialog zur Funkschnittstelle")                                    + TEnd);
  ui->tbtn_Help->setToolTip(TStart +                        tr("Zeige die Programmhilfedatei an")                                           + TEnd);
}

The tool tip texts are also contained in the .ts file, a translation is available, but it just doesn't use the translation when
I change the language.

You mean you change the language after these "setToolTip" methods have been executed?
If so, how would that code miraculously run again?
