setupUi is not a member of my QT application

[lfreeman6490]

The specific error messages are

C2512: 'Ui::Pathloss' no appropriate default constructor available

C1903: unable to recover from previous error(s); stopping compilation

thanks for your help so far, i appreciate it

I can not see your ui file

[lfreeman6490]

I have a 'ui_Pathloss.h' file that is about 800 lines so I can't really post that one. My 'pathloss.ui' file is my design and GUI that I created

[JoeCFD]

@JoeCFD said in setupUi is not a member of my QT application:

Ui::Pathloss

this constructor Ui::Pathloss() does not exist or defined in private section

You need something like the following code in the header:
QT_BEGIN_NAMESPACE

class Ui_FileDeleteProgressDialog
{
public:
Ui_FileDeleteProgressDialog(){}

void setupUi( QDialog * dialog )
 {    
 } // setupUi

};

namespace Ui {
class FileDeleteProgressDialog: public Ui_FileDeleteProgressDialog {};
} // namespace Ui

QT_END_NAMESPACE

[lfreeman6490]

Where in my code should I add that? Would that go in my header file?

Hi,

@lfreeman6490 said in setupUi is not a member of my QT application:

ui(new Pathloss)

It should be:

ui(new Ui::Pathloss)

You are missing the namespace for that class.

[lfreeman6490]

@SGaist Doing that tells me that there is no appropriate default constructor. Do I have to change all instances of 'Pathloss' to 'Ui::Pathloss'?

[JoeCFD]

@lfreeman6490 They are defined in ui_pathloss.h. Open it and check if the class name is Ui_Pathloss. It is possible that the class name is Ui_pathloss?

[lfreeman6490]

@JoeCFD the class is named 'Ui_f_pathloss'. This was automated by QT so I didn't change it

[JoeCFD]

@lfreeman6490 That is a typical Qt error. You define it in Qt Designer with the matching class name.
Load your Qt ui file back to Qt Designer and set class name properly.

[lfreeman6490]

@JoeCFD So I should change that to Ui_Pathloss?

to look like this?

namespace Ui {
    class Ui_Pathloss: public Ui_Pathloss {};
    class FileDeleteProgressDialog: public Ui_FileDeleteProgressDialog {};
} // namespace Ui

[JoeCFD]

@lfreeman6490 You do not do this. Load your Qt ui file back to Qt Designer and set class name properly.
your class name is f_pathloss in the ui file. This is even not a good name.

[lfreeman6490]

@JoeCFD I did that and nothing changed, still getting the same error

[SGaist]

Fix what you have in your pathloss.h file to match what you have in your ui_pathloss.h file.

But it sure does look strange that there's such a name mismatch.

[lfreeman6490]

@SGaist I changed everything to be Ui_Pathloss. I now am getting a new error

"C2664: 'Ui_Ui_Pathloss::setupUi': cannot convert parameter 1 from 'Ui_Pathloss *const' to 'QFrame *'

[SGaist]

Did you modify anything else than what I suggested ?
What is your actual code ?

[lfreeman6490]

@SGaist main .cpp

#include "pathloss.h"
#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    Ui_Pathloss w;
    w.show();
    
    return a.exec();
}

pathloss.cpp

#include "pathloss.h"
#include "ui_pathloss.h"

Ui_Pathloss::Ui_Pathloss(QWidget *parent):
    QWidget(parent),
    ui(new Ui::Ui_Pathloss)
{
    ui->setupUi(this);
}

Ui_Pathloss::~Ui_Pathloss()
{
    delete ui;
}

pathloss.h

#ifndef PATHLOSS_H
#define PATHLOSS_H

#include <QWidget>

namespace Ui {
class Ui_Pathloss;
}

class Ui_Pathloss : public QWidget
{
    Q_OBJECT
    
public:
    explicit Ui_Pathloss(QWidget *parent = 0);
    ~Ui_Pathloss();

private:
    Ui::Ui_Pathloss *ui;
};

#endif // PATHLOSS_H

my ui_Pathloss.h file is too long to post here, but this is the namespace at the bottom

namespace Ui {
    class Ui_Pathloss: public Ui_Pathloss {};
} // namespace Ui

QT_END_NAMESPACE

This post is deleted!

@JoeCFD Change your class to Pathloss in your ui file, not Ui_Pathloss.

[lfreeman6490]

@JoeCFD
throws an error at

{
    ui->setupUi(this);
}

"C2664: 'Ui_Ui_Pathloss::setupUi': cannot convert parameter 1 from 'Ui_Pathloss *const' to 'QFrame *'
