QPixmap not show in .exe file

iliahero

hi. i use this code to showing pixmap:

MainWindow::MainWindow(QWidget *parent)
        : QMainWindow(parent)
        , ui(new Ui::MainWindow)
    {
        ui->setupUi(this);
        QPixmap pm(":/img/board/tic.jpg");
        ui->board->setScaledContents(true);
        ui->board->setPixmap(pm);
    }

this code work when i run my app in release mode in qtcreator but in release folder when i click on .exe file its dont work and this code dont showing the picture.
but when i use the directory of my img(like this: C://dir/dir/...) its showing my picture.

sorry if im not good in english. please help!

How do you deploy your executable? Use windeployqt - it deploys all required plugins (in your case the jpg image plugin).

iliahero

@Christian-Ehrlicher i use this command :
windeployqt.exe --quick .

i dont think my problem is from deploy becuse when i use this code its showing my picture:

QPixmap pm("C:/Users/Other/Desktop/img1.jpg");
    ui->board->setScaledContents(true);
    ui->board->setPixmap(pm);

i think my problem is from loading picture in recourse file in my project

@iliahero
In your code put in qDebug() << QFile::exists(":/img/board/tic.jpg"); (or whatever suitable in place of qDebug()). That tells you whether the file exists. Assuming that returns true the issue is with showing the pixmap, maybe as @Christian-Ehrlicher said; if it returns false you have some other problem.

iliahero

@JonB returned true

@iliahero
So as @Christian-Ehrlicher says it looks like the deployed version has trouble showing a .jpg file. Look in what windeployqt has packaged for your executable, does it contain anything like a plugin to do with showing JPEGs?

@JonB
i use this command :
windeployqt.exe --quick .

my release folder have a folder named imgformats its have :
qgif, gicn, qico, qjpeg, qsvg, qtgs, qtiff, qwbmp, qwebm.

but as i said i think the problem is not from deploy becuse when i use the path of my img in my desktop and deploy my project its showing pixmap

Maybe it's a confusion/mixup of filenames, you have
":/img/board/tic.jpg" and C:/Users/Other/Desktop/img1.jpg, not the same file?

iliahero

my problem solved
The problem was with my system

@hskoglund my problem solved

thanks

@iliahero
Yes, I understand it is weird if it works from an external .jpg file but not from one in a resource which you have checked exists. I do not have an explanation for that.

Unless somehow the resource image does not contain what you think it does.

Get rid of setScaledContents() just in case that is a problem.
Discover whether on the line after QPixmap pm("C:/Users/Other/Desktop/img1.jpg"); that qDebug() << pm.isNull(); returns true or false.
For the sake of a few minutes coding, try in your code extracting :/img/board/tic.jpg to an external file and then setting that as a pixmap. Look at the extracted file and see if it is correct.

@iliahero said in QPixmap not show in .exe file:

The problem was with my system

What does that mean, given that you had checked the file was valid and the deployed image had the necessary plugins?

iliahero

my project was created on "example" directory. i copy my project to another directory
but when i deploy my project, its deploy the older version of my project.
