The following lists the defaults for each window attribute and indicates whether the attribute is applicable to InputOutput and InputOnly windows:

Attribute	Default	InputOutput	InputOnly
background-pixmap	None	Yes	No
background-pixel	Undefined	Yes	No
border-pixmap	CopyFromParent	Yes	No
border-pixel	Undefined	Yes	No
bit-gravity	ForgetGravity	Yes	No
win-gravity	NorthWestGravity	Yes	-
