[SOLVED] QT5: Promoting widget inside a promoted form class

[Jufa]

Yes, it's all ok.

form1.h
@#ifndef FORM1_H
#define FORM1_H

#include <QWidget>

namespace Ui {
class Form1;
}

class Form1 : public QWidget
{
Q_OBJECT

public:
explicit Form1(QWidget *parent = 0);
~Form1();

private:
Ui::Form1 *ui;
};

#endif // FORM1_H
@

form2.h
@#ifndef FORM2_H
#define FORM2_H

#include <QWidget>

namespace Ui {
class Form2;
}

class Form2 : public QWidget
{
Q_OBJECT

public:
explicit Form2(QWidget *parent = 0);
~Form2();

private:
Ui::Form2 *ui;
};

#endif // FORM2_H

MainWindows contains a widget. This widget is promoted to Form1, wich contains a widget promoted to Form2.

What should I check now?

Which IDE & compiler do you use? I have same construction(promoted widget in promoted widget) and it works in VS(msvc) & QtCreator(gcc). But your linker somhow can't find object file with Form2... Try to include Form2 header in Form1 header to ensure it will be compiled....

[Sam]

Can you attach an image of the Object Inspector/Explorer of the MainWindow .

[Jufa]

AcerExtensa, I have VS & QTCreator(vc). I have tried including form2.h in form1.h, but the same result.

Sam, this is the image:

Nops not this image . open mainwindow.ui the object inspector is on extreme right just above the property explorer.

[Jufa]

Oh, sorry. This one:

Here is project with promoted widget in promoted widget of main widget. It works in QtCreator(gcc) and in MSVC: "PromoWidget.tar.gz":http://xplatforms.de/PromoWidget.tar.gz

Test it in your Environment.

[Jufa]

I'll get crazy with this. Your project works perfect! I have been comparing file by file and all seems exactly the same. But mine keeps giving me this error.

This is my project (ultra basic, just like yours):

Thanks for all your responses and your time!

I can compile and run your project without problems whatsoever. Have you tried cleaning your project and rerunning qmake? Sometimes hitting rebuild isn't enough.

[Jufa]

I don't know what you mean with "clean" but I have deleted the debug folder and recompile... and it worked! Thanks everyone! I'll change the post to "solved"!

Right Click on your Project Tree there is an option in the context Menu "Clean" , which will clear the moc files generated by the compiler in debug and release folder of your project.

[Jufa]

Thanks! That made the trick!

thread marked as solved.
