namespace "Ui" has no member "xxxxx"

[aftershocker1]

Hello, first post on here and looking for some guidance. I am using Qt in VS2019. I am just making a wee test application to try and learn what I am doing and come across an error message. In the ItemAddDialog.h file I have a red error line under

private:

Ui::ItemAddDialog ui; //error under "ItemAddDialog"

The error message says "namespace "Ui" has no member "itemAddDialog".

These are the error messages when I run in VS.

1>C:\Users\gh185103\source\repos\QtStoreInvApp\QtStoreInvApp\itemadddialog.h(15,6): error C2039: 'ItemAddDialog': is not a member of 'Ui'

1>C:\Users\gh185103\source\repos\QtStoreInvApp\QtStoreInvApp\x64\Debug\uic\ui_itemadddialog.h(99): message : see declaration of 'Ui'

1>C:\Users\gh185103\source\repos\QtStoreInvApp\QtStoreInvApp\itemadddialog.h(15,20): error C2460: 'ItemAddDialog::ui': uses 'ItemAddDialog', which is being defined

1>C:\Users\gh185103\source\repos\QtStoreInvApp\QtStoreInvApp\itemadddialog.h(6): message : see declaration of 'ItemAddDialog'

Any help would be fantastic! Thanks

So look into the ui class and you will see that the compiler is correct.

Hi and welcome to the forums

But what is ItemAddDialog ?

Did you make a custom widget you called ItemAddDialog ?

it should generate a file called ui_ItemAddDialog.h ?

Do you use the plugin for Qt for Vs ?

[aftershocker1]

ItemAddDialog is a Qt Widgets class so has an itemadddialog.cpp, itemadddialog.h & itemadddialog.ui.

I used the plugin for Qt for VS2019.

I can see a file called ui_ItemAddDialog.h in the x64 ->debug folder.

The code for the problamatic .h file is....

#pragma once

#include <QWidget>
#include "ui_itemadddialog.h"

class ItemAddDialog : public QWidget
{
Q_OBJECT

public:
ItemAddDialog(QWidget *parent = Q_NULLPTR);
~ItemAddDialog();

private:
Ui::ItemAddDialog ui; //red error in ItemAddDialog
};

Hope that can help you help me!

@aftershocker1 said in namespace "Ui" has no member "xxxxx":

#include "ui_itemadddialog.h"
Ui::ItemAddDialog ui; //red error in ItemAddDialog

So what is in ui_itemadddialog.h? It dsoes not sound like it defines Ui::ItemAddDialog.
