Still the safe 'load' # provedes a speciall case. The Tk can be divided into 4 groups, # that each has a safe handling procedure. # # - "::tkcon::SafeItem" handles commands like 'button', 'canvas' ...... # Each of these functions has the window name as first argument. # - "::tkcon::SafeManage" handles commands like 'pack', 'place', 'grid', # 'winfo', which can have multiple window names as arguments. # - "::tkcon::SafeWindow" handles all windows, such as '.'. For every # window created, a new alias is formed which also is handled by # this function. # - Other (e.g. bind, bindtag, image), which need their own function. # ## These functions courtesy Jan Nijtmans (nijtmans@nici.kun.nl) ## if {[string compare [info command tk] tk]} { proc tk {option args} { if {![string match app* $option]} { error "wrong option \"$option\": should be appname" } return "tkcon.tcl" } } if {[string compare [info command toplevel] toplevel]} { proc toplevel {name args} { eval frame $name $args pack $name } } proc ::tkcon::SafeSource {i f} { set fd [open $f r] set r [read $fd] close $fd if {[catch {interp eval $i $r} msg]} { error $msg } } proc ::tkcon::SafeOpen {i f {m r}} { set fd [open $f $m] interp transfer {} $fd $i return $fd } proc ::tkcon::SafeLoad {i f p} { global tk_version tk_patchLevel tk_library auto_path if {[string compare $p Tk]} { load $f $p $i } else { foreach command {button canvas checkbutton entry frame label listbox message radiobutton scale scrollbar spinbox text toplevel} { $i alias $command ::tkcon::SafeItem $i $command } $i alias image ::tkcon::SafeImage $i foreach command {pack place grid destroy winfo} { $i alias $command ::tkcon::SafeManage $i $command } if {[llength [info command event]]} { $i alias event ::tkcon::SafeManage $i $command } frame .${i}_dot -width 300 -height 300 -relief raised pack .${i}_dot -side left $i alias tk tk $i alias bind ::tkcon::SafeBind $i $i alias bindtags ::tkcon::SafeBindtags $i $i alias . ::tkcon::SafeWindow $i {} foreach var {tk_version tk_patchLevel tk_library auto_path} { $i eval set $var [list [set $var]] } $i eval { package provide Tk $tk_version if {[lsearch -exact $auto_path $tk_library] < 0} { lappend auto_path $tk_library } } return "" } } proc ::tkcon::SafeSubst {i a} { set arg1 "" foreach {arg value} $a { if {![string compare $arg -textvariable] || ![string compare $arg -variable]} { set newvalue "[list $i] $value" global $newvalue if {[interp eval $i info exists $value]} { set $newvalue [interp eval $i set $value] } else { catch {unset $newvalue} } $i eval trace variable $value rwu \{[list tkcon set $newvalue $i]\} set value $newvalue } elseif {![string compare $arg -command]} { set value [list $i eval $value] } lappend arg1 $arg $value } return $arg1 } proc ::tkcon::SafeItem {i command w args} { set args [::tkcon::SafeSubst $i $args] set code [catch "$command [list .${i}_dot$w] $args" msg] $i alias $w ::tkcon::SafeWindow $i $w regsub -all .${i}_dot $msg {} msg return -code $code $msg } proc ::tkcon::SafeManage {i command args} { set args1 "" foreach arg $args { if {[string match . $arg]} { set arg .${i}_dot } elseif {[string match .* $arg]} { set arg ".${i}_dot$arg" } lappend args1 $arg } set code [catch "$command $args1" msg] regsub -all .${i}_dot $msg {} msg return -code $code $msg } # # FIX: this function doesn't work yet if the binding starts with '+'. # proc ::tkcon::SafeBind {i w args} { if {[string match . $w]} { set w .${i}_dot } elseif {[string match .* $w]} { set w ".${i}_dot$w" } if {[llength $args] > 1} { set args [list [lindex $args 0] \ "[list $i] eval [list [lindex $args 1]]"] } set code [catch "bind $w $args" msg] if {[llength $args] <2 && $code == 0} { set msg [lindex $msg 3] } return -code $code $msg } proc ::tkcon::SafeImage {i option args} { set code [catch "image $option $args" msg] if {[string match cr* $option]} { $i alias $msg $msg } return -code $code $msg } proc ::tkcon::SafeBindtags {i w {tags {}}} { if {[string match . $w]} { set w .${i}_dot } elseif {[string match .* $w]} { set w ".${i}_dot$w" } set newtags {} foreach tag $tags { if {[string match . $tag]} { lappend newtags .${i}_dot } elseif {[string match .* $tag]} { lappend newtags ".${i}_dot$tag" } else { lappend newtags $tag } } if {[string match $tags {}]} { set code [catch {bindtags $w} msg] regsub -all \\.${i}_dot $msg {} msg } else { set code [catch {bindtags $w $newtags} msg] } return -code $code $msg } proc ::tkcon::SafeWindow {i w option args} { if {[string match conf* $option] && [llength $args] > 1} { set args [::tkcon::SafeSubst $i $args] } elseif {[string match itemco* $option] && [llength $args] > 2} { set args "[list [lindex $args 0]] [::tkcon::SafeSubst $i [lrange $args 1 end]]" } elseif {[string match cr* $option]} { if {[llength $args]%2} { set args "[list [lindex $args 0]] [::tkcon::SafeSubst $i [lrange $args 1 end]]" } else { set args [::tkcon::SafeSubst $i $args] } } elseif {[string match bi* $option] && [llength $args] > 2} { set args [list [lindex $args 0] [lindex $args 1] "[list $i] eval [list [lindex $args 2]]"] } set code [catch ".${i}_dot$w $option $args" msg] if {$code} { regsub -all .${i}_dot $msg {} msg } elseif {[string match conf* $option] || [string match itemco* $option]} { if {[llength $args] == 1} { switch -- $args { -textvariable -
