QMacStyle::standardIcon returns icons that don't match the mac theme.

[micheal]

Using Qt 5.9.6 on Mac High Sierra, I'm tasked with creating a window with a custom titlebar, while maintaining some of the native look and feel across platforms.

I was hoping to grab the window control icons using QStyle::standardIcon, which I believe should be calling the implementation of QMacStyle::standardIcon

I'm passing QStyle::SP_TitleBarCloseButton, QStyle::SP_TitleBarMaxButton and QStyle::SP_TitleBarMinButton.

The icons that are returned don't match the native icons at all. Would an upgrade to Qt 5.12 help, or will I need to create my own images to try emulate the native look?

Alternative approaches also welcome!

Hi and welcome to devnet,

Upgrading is a good idea since 5.12 is the current LTS.

That said, what are you getting ?

[micheal]

Upgrading has been on the back burner for a while, I'm in favour of it and could certainly make a good argument for doing it sooner if it would fix this problem!

These are the icons that are being returned:

Can you provide a minimal sample code that reproduces that ?

[micheal]

Here's a short sample, which results in the following window:

int main(int argc, char* argv[])
{
	QApplication app(argc, argv);
	QMainWindow window;

	QStyle *style = app.style();
	QIcon closeIcon = style->standardIcon(QStyle::SP_TitleBarCloseButton);

	QPushButton button;
	button.setIcon(closeIcon);

	window.setCentralWidget(&button);
	window.show();

	return app.exec();
}

I tested this out on 5.12, making sure to first specify

setStyle(QStyleFactory::create("macintosh"))

but got the same result.

Solution is to make images that look native and use those instead, not much of a solution but it seems to be the only option.

@micheal
I build my app on both mac and windows and use

app->setStyle("fusion");

I get the native Mac look and feel on the Mac and the windows look and feel on windows with just that piece of code.
