Hi guys.

Could you please tell me how I can know the width and height of a device?

like system.displayWidth –

or get systemHeight, –

or something like that.

Ijust want to write the line so the program “returns” to me the correct width and height

Thanks

Do you want the device’s actual pixels?  display.pixelWidth, display.pixelHeight

Do you want the content area size:  display.contentWidth, display.contentHeight
