# Ttk widget set initialization script.

### Source library scripts.
#

    variable library
    if {![info exists library]} {
	set library [file dirname [info script]]
    }
}

source [file join $::ttk::library keynav.tcl]

source [file join $::ttk::library cursors.tcl]
source [file join $::ttk::library icons.tcl]
source [file join $::ttk::library utils.tcl]

## ttk::deprecated $old $new --
#	Define $old command as a deprecated alias for $new command
#	$old and $new must be fully namespace-qualified.
#
proc ::ttk::deprecated {old new} {
    interp alias {} $old {} ttk::do'deprecate $old $new
}
## do'deprecate --
#	Implementation procedure for deprecated commands --
#	issue a warning (once), then re-alias old to new.
#
proc ::ttk::do'deprecate {old new args} {
    deprecated'warning $old $new
    interp alias {} $old {} $new

## deprecated'warning --
#	Gripe about use of deprecated commands.
#
proc ::ttk::deprecated'warning {old new} {
    puts stderr "$old deprecated -- use $new instead"
}

### Forward-compatibility.
#
# ttk::panedwindow used to be named ttk::paned.  Keep the alias for now.
#
::ttk::deprecated ::ttk::paned ::ttk::panedwindow

    ### Widgets.
    #	Widgets are all defined in the ::ttk namespace.
    #
    #	For compatibility with earlier Tile releases, we temporarily
    #	create aliases ::tile::widget, and ::t$widget.
    #	Using any of the aliases will issue a warning.
    #

	    deprecated ::tile::$wc ::ttk::$wc
	    namespace eval ::tile [list namespace export $wc]
	}

### ::ttk::ThemeChanged --
#	Called from [::ttk::style theme use].
#	Sends a <<ThemeChanged>> virtual event to all widgets.
#
proc ::ttk::ThemeChanged {} {

### Public API.
#

proc ::ttk::themes {{ptn *}} {
    set themes [list]

    foreach pkg [lsearch -inline -all -glob [package names] ttk::theme::$ptn] {
	lappend themes [namespace tail $pkg]
    }

    return $themes
}

## ttk::setTheme $theme --
#	Set the current theme to $theme, loading it if necessary.
#
proc ::ttk::setTheme {theme} {
    variable currentTheme ;# @@@ Temp -- [::ttk::style theme use] doesn't work
    if {$theme ni [::ttk::style theme names]} {
