Compiler Fehler in moc.. Hilfe!

Hi Leute, dass hier ist der Fehler, und ich kann damit garnichts anfangen:

hier die Header und C++ datei. Die "ui_login.h" ist eine vom Designer erzeugte Datei.

Moin!

Schau dir nochmal in der Doku folgendes an über "Using a component in your application", Stichwort "multiple inheritance approach".

Ich habe gehofft er kommt selbst drauf wenn er die Klassendeklaration sieht... naja hätte ja auch qt3 sein können

[Limexx]

habs nun gelesen, ich brauche die UI aber public... aber aus dem Text wird mir nicht ganz klar, was ich machen soll...

btw ich werkle mit QT erst 3-4 Tage rum, also habe ich noch so gut wie NULL erfahrung

[Christian81]

Und was spricht dagegen, Ui_mw_login in class x_Login als public zu definieren?

[Flachkoepper]

Deine Klassendeklaration muss auch die Vererbung von QMainWindow beinhalten:

Code: Alles auswählen

 class x_Login : public QMainWindow, public Ui_mw_login
{ ... 

Ach ja, und setupUi(this) nicht vergessen.

Du solltest Dich echt erstmal mit C++ Grundlagen beschäftigen bzw. nochmal lesen was ich geschrieben habe. Flachkoepper hat natürlich auch Recht.
