Push Button with image?

[szisziszilvi]

If you want to use the resource system, is it not that there is a ":/" missing? In my application I use resiurce files like this:
QFile qfi(":/texts/res/usageNotes.txt");
This works:

QIcon icon;
    QPixmap qpm;
 
    if(qpm.load(":/img/myImage.jpg"))
    {
        icon.addPixmap(qpm);
        ui->pushButton->setIcon(icon);
    }
    else ui->label->setText("nincs betöltve");

QIcon icon;
    QPixmap qpm;

    if(qpm.load(":/img/myImage.jpg"))
    {
        icon.addPixmap(qpm);
        ui->pushButton->setIcon(icon);
    }
    else ui->label->setText("nincs betöltve");

To copy to clipboard, switch view to plain text mode 

Otherwise I have the guess that the absolute path works because the executable file is not generated in the same directory as the code, so the executable file whilst working is trying to find the image on the relative path from itself, where is actually nothing, as there might be even no directory like that.

Simplest way to set image on the Push Button::
btn = (QPushButton *)ui->btn;
btn->setIconSize((QSize(56,68)));
QPixmap* pixmap1 = new QPixmap(":/images/orange.bmp");
QIcon icon1(*pixmap1);
btn->setIcon(icon1);

I think this might help you..

btn = (QPushButton *)ui->btn;

btn = (QPushButton *)ui->btn;

To copy to clipboard, switch view to plain text mode 

Why this cast ? (which is an old C-style cast anyway).

[Gokulnathvc]

Anyway its works fine. Finding the simplest way to use yet more powerful

[unit]

ui->btn->setIconSize((QSize(56,68))); isn't work?

and in qt don't use old c-style cast. you have static_cast and object_cast

You shouldn't need any casts here. Be it implicit or explicit, C or C++ style.

[Gokulnathvc]

btn = (QPushButton *)ui->btn;
btn->setIconSize((QSize(56,68)));

[wysota]

btn = (QPushButton *)ui->btn;
btn->setIconSize((QSize(56,68)));

But why the cast? Not that this is relevant to the subject (it was about a missing file) but since we're already here, let's solve this situation too.
