Flags

The term Flag in the context of this window manager refers to features that can be enabled on a per window basis via client rules.

The idea of flags stems from the many patches for that introduce new rule options, often storing a new value in the Client struct.

One example of this is the swallow patch which adds two new int values of isterminal and noswallow both to the rules list and the Client struct.

Instead of having multiple boolean values (iscentered, isfloating, isfakefullscreen, etc.) one could instead have a single unsigned long value that could hold up to 64 flags (one flag per bit). That is exactly what flags do and this makes it easier to set up rules.

Example rule combining Floating and SwitchWorkspace flags:

static const Rule clientrules[] = {
	...
	{ .class = "Gimp", .workspace = "5", .flags = Floating|SwitchWorkspace },
	...

Client flags can also be changed externally using the toggleclientflag function.

MoveResize	Used internally to indicate that the client is being moved or resized	Floating
MovePlace	Used internally to indicate that the client is being moved within stack	Floating
NeverFocus	Indicates that the client should never receive focus	Focus
Locked	Used by setfullscreen, prevents state change	Fullscreen
RestoreFakeFullScreen	Internal flag that indicates that fake fullscreen should be restored when exiting actual fullscreen	Fullscreen
