Binds a specified fvwm command Function to an edge of the screen. Direction may be one of "North", "Top", "West", "Left", "South", "Bottom", "Right" and "East". If Function is omitted the binding for this edge is removed. If EdgeCommand is called without any arguments all edge bindings are removed.

Function is executed when the mouse pointer enters the invisible pan frames that surround the visible screen. The binding works only if EdgeThickness is set to a value greater than 0. If a function is bound to an edge, scrolling specified by EdgeScroll is disabled for this edge. It is possible to bind a function only to some edges and use the other edges for scrolling. This command is intended to raise or lower certain windows when the mouse pointer enters an edge. FvwmAuto can be used get a delay when raising or lowering windows. The following example raises FvwmButtons if the mouse pointer enters the top edge of the screen.

# Disable EdgeScrolling but make it possible
# to move windows over the screen edge
EdgeResistance -1
Style * EdgeMoveDelay 250
Style * EdgeMoveResistance 20

# Set thickness of the edge of the screen to 1
EdgeThickness 1

# Give focus to FvwmButtons if the mouse
# hits top edge
EdgeCommand Top Next (FvwmButtons) Focus
# Make sure the Next command matches the window
Style FvwmButtons CirculateHit

Module FvwmButtons
Module FvwmAuto 100 "Silent AutoRaiseFunction" \
     "Silent AutoLowerFunction"

# If any window except FvwmButtons has
# focus when calling this function
# FvwmButtons are lowered
DestroyFunc AutoLowerFunction
AddToFunc AutoLowerFunction
+ I Current (!FvwmButtons) All (FvwmButtons) Lower

# If FvwmButtons has focus when calling this function raise it
DestroyFunc AutoRaiseFunction
AddToFunc AutoRaiseFunction
+ I Current (FvwmButtons) Raise

Normally, the invisible pan frames are only on the screen edges that border virtual pages. If a screen edge has a command bound to it, the pan frame is always created on that edge.
