How to make background's alpha? about slib HOT 7 CLOSED

m_view->setAlpha(0.8)

This will set the alpha of the view object.

To set the background window's alpha, use following snippet

getMainWindow()->setAlpha(0.8);

from slib.

Yes,I want to set alpha of the view object.
But it seems to be ineffective.

You can confirm the effect by setting the background color of the container.

getPager()->setBackgroundColor(slib::Color::Black);

I want to set area of title bar's alpha only,not all pager.
thanks.

It's OK:

slib::Color m_color;
m_color.setRGBA(100, 100, 100, 100);//use Color Object to set alpha.
m_view->setBackgroundColor(m_color);//OK,It's alpha.

m_view->setBackgroundColor(slib::Color(100, 100, 100, 100));

from slib.

Thanks.
