Updating Icons after a QResource::registerResource()

[romulodefarias]

I have a program that changes the resources file on the fly (QResource::registerResource()) successfully.

The problem is that my icons aren't changing automatically.

I've implemented a few solutions which work, but none of them seemed really good for me...

Take a look:

Solution 1
It isn't a really bad solution, but it's so handmade for me. This project has a lot of Icons

QPixmap pix(":/images/save");
QIcon icon(pix);
ui->myBtn->setIcon(icon);

Solutuion 2
Really bad, performance issues, also too handmade.

QObject::disconnect(ui->myBtn, SIGNAL(clicked()), this, SLOT(changeResources()));
ui->setupUi(this);
QObject::connect(ui->myBtn, SIGNAL(clicked()), this, SLOT(changeResources()));

I thought calling the window's QWidget::update() method would do the job but unfortunately, no.

Is there some smarter solution?

Hi and welcome to devnet,

What about mimicking the language change system ? Create a new event type that you'll post when changing a resource and each widget that would like to update its icons can listen to that event and act accordingly.

Hope it helps
