### Load widget bindings.

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

# (not enough to justify their own file...)
#
bind TLabelframe <<Invoke>> { tk::TabToWindow [tk_focusNext %W] }

### Load settings for built-in themes:
#

variable library
# "default" always present:
uplevel #0 [list source [file join $library defaults.tcl]]
set builtinThemes [style theme names]
foreach {theme scripts} {
classic classicTheme.tcl

foreach script $scripts {
uplevel #0 [list source [file join $library $script]]
}
}
}
}
ttk::LoadThemes; rename ::ttk::LoadThemes {}
### Select platform-specific default theme:
#
# Notes:
# + On OSX, aqua theme is the default
# + On Windows, xpnative takes precedence over winnative if available.
# + On X11, users can use the X resource database to
# specify a preferred theme (*TkTheme: themeName);
# otherwise "default" is used.
#
proc ttk::DefaultTheme {} {
set preferred [list aqua vista xpnative winnative]
set userTheme [option get . tkTheme TkTheme]
if {$userTheme ne {} && ![catch {
uplevel #0 [list package require ttk::theme::$userTheme]
}]} {

}
foreach theme $preferred {

}
}
return "default"
}
ttk::setTheme [ttk::DefaultTheme] ; rename ttk::DefaultTheme {}
