QComboBox cannot show the icon

king558

I am using Qt5.8.0 and QtCreator 4.2.1. The resource was added before. The icon cannot displayed. Only with absolute path C:/img/icon/ works. And I compile the source with 5.9.0 with QtCreator 4.3.0 without any modification. It shows the icon. Someone can tell me the reason and solution.

#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi( this );
    ui->comboBox->addItem( QIcon( ":/img/icon/star.png" ), "Test1" );
    ui->comboBox->addItem( QIcon( ":/img/icon/pencil.png" ), "Test2" );
    ui->comboBox->addItem( QIcon( ":/img/icon/delete.png" ), "Test3" );
}

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

Hi
If you go to the resource in the project view, find the file and right click.
What paths is shown ?

Is the actual img folder located on c:/ ?

The Path is correct. Its Real Path is C:\Users...\Documents\Qt5.8.0\15_QComboBox\icon

Does it show a preview ?
Path seems correct so I wonder if it really can find them

If you click on the top resource file and select
alt text
(missing files)

Does the star/delete/pencil stay?

Now it shows the icon, what I did is, run qmake and rebuild. Thx all for help.

Oh so it did not recompile it by itself :)
Sometimes one must run qmake manually.
