	pressed 0
    	pressX	-
	pressY	-

## Bindings:
#
bind TPanedwindow <ButtonPress-1> 	{ ttk::panedwindow::Press %W %x %y }
bind TPanedwindow <B1-Motion>		{ ttk::panedwindow::Drag %W %x %y }
bind TPanedwindow <ButtonRelease-1> 	{ ttk::panedwindow::Release %W %x %y }

bind TPanedwindow <Motion> 		{ ttk::panedwindow::SetCursor %W %x %y }
bind TPanedwindow <Enter> 		{ ttk::panedwindow::SetCursor %W %x %y }
bind TPanedwindow <Leave> 		{ ttk::panedwindow::ResetCursor %W }
# See <<NOTE-PW-LEAVE-NOTIFYINFERIOR>>
bind TPanedwindow <<EnteredChild>>	{ ttk::panedwindow::ResetCursor %W }


## Sash movement:
#
proc ttk::panedwindow::Press {w x y} {
    variable State

    lassign [$w identify $x $y] sash element
    if {![info exists sash] || $sash eq ""} {
    	set State(pressed) 0

    set State(pressed) 	1
    set State(pressX) 	$x
    set State(pressY) 	$y

    set State(sashPos)	[$w sashpos $sash]
}

}

proc ttk::panedwindow::Release {w x y} {
    variable State
    set State(pressed) 0
    SetCursor $w $x $y
}

## Cursor management:
#
proc ttk::panedwindow::ResetCursor {w} {
    variable State
    if {!$State(pressed)} {
	$w configure -cursor {}
    }
}

proc ttk::panedwindow::SetCursor {w x y} {
    variable ::ttk::Cursors

    if {![llength [$w identify $x $y]]} {
    	ResetCursor $w
    } else {
    	# Assume we're over a sash.
	switch -- [$w cget -orient] {
	    horizontal 	{ $w configure -cursor $Cursors(hresize) }
	    vertical 	{ $w configure -cursor $Cursors(vresize) }
	}
    }
