# tkfbox.tcl -- # # Implements the "TK" standard file selection dialog box. This # dialog box is used on the Unix platforms whenever the tk_strictMotif # flag is not set. # # The "TK" standard file selection dialog box is similar to the # file selection dialog box on Win95(TM). The user can navigate # the directories by clicking on the folder icons or by # selecting the "Directory" option menu. The user can select # files by clicking on the file icons or by entering a filename # in the "Filename:" entry. # # RCS: @(#) $Id: tkfbox.tcl,v 1.68.2.3 2009/10/22 10:27:58 dkf Exp $ # # Copyright (c) 1994-1998 Sun Microsystems, Inc. # # See the file "license.terms" for information on usage and redistribution # of this file, and for a DISCLAIMER OF ALL WARRANTIES. # package require Ttk #---------------------------------------------------------------------- # # I C O N L I S T # # This is a pseudo-widget that implements the icon list inside the # ::tk::dialog::file:: dialog box. # #---------------------------------------------------------------------- # ::tk::IconList -- # # Creates an IconList widget. # proc ::tk::IconList {w args} { IconList_Config $w $args IconList_Create $w } proc ::tk::IconList_Index {w i} { upvar #0 ::tk::$w data ::tk::$w:itemList itemList if {![info exists data(list)]} { set data(list) {} } switch -regexp -- $i { "^-?[0-9]+$" { if {$i < 0} { set i 0 } if {$i >= [llength $data(list)]} { set i [expr {[llength $data(list)] - 1}] } return $i } "^active$" { return $data(index,active) } "^anchor$" { return $data(index,anchor) } "^end$" { return [llength $data(list)] } "@-?[0-9]+,-?[0-9]+" { foreach {x y} [scan $i "@%d,%d"] { break } set item [$data(canvas) find closest \ [$data(canvas) canvasx $x] [$data(canvas) canvasy $y]] return [lindex [$data(canvas) itemcget $item -tags] 1] } } } proc ::tk::IconList_Selection {w op args} { upvar ::tk::$w data switch -exact -- $op { "anchor" { if {[llength $args] == 1} { set data(index,anchor) [tk::IconList_Index $w [lindex $args 0]] } else { return $data(index,anchor) } } "clear" { if {[llength $args] == 2} { foreach {first last} $args { break } } elseif {[llength $args] == 1} { set first [set last [lindex $args 0]] } else { error "wrong # args: should be [lindex [info level 0] 0] path\ clear first ?last?" } set first [IconList_Index $w $first] set last [IconList_Index $w $last] if {$first > $last} { set tmp $first set first $last set last $tmp } set ind 0 foreach item $data(selection) { if { $item >= $first } { set first $ind break } incr ind } set ind [expr {[llength $data(selection)] - 1}] for {} {$ind >= 0} {incr ind -1} { set item [lindex $data(selection) $ind] if { $item <= $last } { set last $ind break } } if { $first > $last } { return } set data(selection) [lreplace $data(selection) $first $last] event generate $w <> IconList_DrawSelection $w } "includes" { set index [lsearch -exact $data(selection) [lindex $args 0]] return [expr {$index != -1}] } "set" { if { [llength $args] == 2 } { foreach {first last} $args { break } } elseif { [llength $args] == 1 } { set last [set first [lindex $args 0]] } else { error "wrong # args: should be [lindex [info level 0] 0] path\ set first ?last?" } set first [IconList_Index $w $first] set last [IconList_Index $w $last] if { $first > $last } { set tmp $first set first $last set last $tmp } for {set i $first} {$i <= $last} {incr i} { lappend data(selection) $i } set data(selection) [lsort -integer -unique $data(selection)] event generate $w <> IconList_DrawSelection $w } } } proc ::tk::IconList_CurSelection {w} { upvar ::tk::$w data return $data(selection) } proc ::tk::IconList_DrawSelection {w} { upvar ::tk::$w data upvar ::tk::$w:itemList itemList $data(canvas) delete selection $data(canvas) itemconfigure selectionText -fill black $data(canvas) dtag selectionText set cbg [ttk::style lookup TEntry -selectbackground focus] set cfg [ttk::style lookup TEntry -selectforeground focus] foreach item $data(selection) { set rTag [lindex [lindex $data(list) $item] 2] foreach {iTag tTag text serial} $itemList($rTag) { break } set bbox [$data(canvas) bbox $tTag] $data(canvas) create rect $bbox -fill $cbg -outline $cbg \ -tags selection $data(canvas) itemconfigure $tTag -fill $cfg -tags selectionText } $data(canvas) lower selection return } proc ::tk::IconList_Get {w item} { upvar ::tk::$w data upvar ::tk::$w:itemList itemList set rTag [lindex [lindex $data(list) $item] 2] foreach {iTag tTag text serial} $itemList($rTag) { break } return $text } # ::tk::IconList_Config -- # # Configure the widget variables of IconList, according to the command # line arguments. # proc ::tk::IconList_Config {w argList} { # 1: the configuration specs # set specs { {-command "" "" ""} {-multiple "" "" "0"} } # 2: parse the arguments # tclParseConfigSpec ::tk::$w $specs "" $argList } # ::tk::IconList_Create -- # # Creates an IconList widget by assembling a canvas widget and a # scrollbar widget.
