ich bin gerade dabei einen kleinen Vortrag über das Signal & Slot Konzept in Qt zu schreiben.
Ich würde gern ein kleines Tutorial mit reinnehmen,
das Auge ißt ja bekanntlich mit
Leider muss ich zugeben, dass C++ so gar nicht meine Stärke ist
und vielleicht mag einer von Euch mal schnell drüberschauen
und mir beim Fehler helfen.
Hier der Code der Main.cpp:
Code: Alles auswählen
#include "ui_HelpBrowser.h"
#include <QtGui/QtGui>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
app.setQuitOnLastWindowClosed(true);
QMainWindow *form = new QMainWindow;
Ui::MainWindow ui;
ui.setupUi(form);
ui.textBrowser->setSource(QString("http://doc.trolltech.com/"));
form->show();
return app.exec();
}Code: Alles auswählen
main.cpp: In function `int qMain(int, char**)':
main.cpp:10: error: `MainWindow' is not a member of `Ui'
main.cpp:10: error: expected `;' before "ui"
main.cpp:11: error: `ui' undeclared (first use this function)
main.cpp:11: error: (Each undeclared identifier is reported only once for each f
unction it appears in.)
