Opening windows hidden
« on: December 25, 2020, 01:23:15 pm »
Good day,

I'd like to open a render window in hidden mode, though I found out this is not currently implemented and requires dealing with openGl directly.

Am I right, is there a way I didn't see ?

Thank you,

Jean-François

hello
how exactly would be a hidden window? a window that can't be seen, but yet you can draw and use events from it? should it appear in the OS' taskbar (since if it does, may not be hidden enough for what you are planning)?

I believe there is no such thing built in SFML, but if you explain better what you are trying to do maybe we can help.
Visit my game site (and hopefully help funding it? )

Hello,

At the moment, I have an application that can launch sub-systems.

I sometimes need to instanciate a window have it invisible as its initial state.
At the moment I instanciate and immediatly set it invisible:

void setVisible (bool visible)

This makes it flash thus I'd prefer start it invisible.

You could create the window tiny (1x1, for example) and quickly move it offscreen and resize it. You can then set it to be 'hidden'. This can be much less noticeable than working with a full size window.

That said, it looks like the ability to open a window without it being visible could well be available in the future...

Thanks I'll try it.

I remember from last time I tested this solution it was indeed kind of working.
