Transient - bakkeby/dusk GitHub Wiki
Transient is an internal flag that is set when a client window has the TRANSIENT_FOR X window
hint set referring to an existing client (i.e. the parent window).
This is a way for an application to indicate to the window manager that the new window being raised is meant to be a short lived one and this is typically used for dialog boxes, splash screens, etc.
Transient window are treated different to normal windows:
- client rules do not apply to transient windows unless transient specific rules are used
- transient windows are by default floating](Floating)
- transient windows are by default centered within the parent window
- transient windows never swallow terminals
Setting the Transient flag as part of client rules have little to no effect besides preventing
the window from swallowing a terminal, as it says nothing to indicate which the parent window is.
