Some notes about transitioning code from ttk::treeview to tablelist.
O: is old code with treeview.
N: is new code with tablelist.
N2: transforms hidden columns into row attributes
N: Using tablelist
package require tablelist_tile
O: Creation
ttk::treeview $win.tree -height 20 \
-columns {type status leftfull leftname leftsize leftdate rightfull rightname rightsize rightdate} \
-displaycolumns {leftsize leftdate rightsize rightdate}
N: Creation
tablelist::tablelist $win.tree -height 20 \
-movablecolumns no -setgrid no -showseparators yes \
-columns {0 "Structure" 0 "" 0 "" 0 "" 0 Name 0 Size 0 Date 0 "" 0 Name 0 Size 0 Date}
N2: Only visible columns kept
tablelist::tablelist $win.tree -height 20 \
-movablecolumns no -setgrid no -showseparators yes \
-columns {0 "Structure" 0 Name 0 Size 0 Date 0 Name 0 Size 0 Date}
O: Scroll
$tree configure -yscroll "$vsb set" -xscroll "$hsb set"
N: Scroll
$tree configure -yscrollcommand "$vsb set" -xscrollcommand "$hsb set"
O: treeview's heading is set in -columns in tablelist
$tree heading \#0 -text "Structure"
$tree heading leftname -text "Name"
$tree column leftsize -stretch 0 -width 70 -anchor e
N: tablelist gives logical names to columns like this
$tree columnconfigure 0 -name structure
$tree columnconfigure 1 -name type -hide 1
$tree columnconfigure 4 -name leftname -hide 1
$tree columnconfigure 5 -name leftsize -align right
N2: No hidden columns
$tree columnconfigure 1 -name leftname -hide 0
O: Bindings
bind $tree <Button-3> "[mymethod ContextMenu] %x %y %X %Y"
bind $tree <Double-ButtonPress-1> "[mymethod DoubleClick] %x %y"
bind $tree <Key-Return> [mymethod KeyReturn]
N:
set bodyTag [$tree bodytag]
bind $bodyTag <<Button3>> [bind TablelistBody <Button-1>]
bind $bodyTag <<Button3>> +[bind TablelistBody <ButtonRelease-1>]
bind $bodyTag <<Button3>> "+[mymethod ContextMenu] %W %x %y %X %Y"
bind $bodyTag <Double-1> "[mymethod DoubleClick] %W %x %y"
bind $bodyTag <Key-Return> [mymethod KeyReturn]
O: Clear tree
$tree delete [$tree children {}]
N:
$tree delete 0 end
O: Configure/Create root node
$tree set {} type directory
N:
set topIndex [$tree insertchild root end {}]
$tree cellconfigure $topIndex,type -text directory
O: Node's Children
set todo [$tree children {}]
lappend todo {*}[$tree children $node]
N:
set todo [$tree childkeys root]
lappend todo {*}[$tree childkeys $node]
O: Getting cell info
set status [$tree set $node status]
N:
set status [$tree cellcget $node,status -text]
N2: Hidden is now row attribute
set status [$tree rowattrib $node status]
O:
A loop to open/collapse all
N:
$tree expandall
$tree collapseall
O: Handle coords in a binding
method DoubleClick {x y} {
set node [$tree identify row $x $y]
set col [$tree identify column $x $y]
set colname [$tree column $col -id]
}
N:
method DoubleClick {W x y} {
foreach {W x y} [tablelist::convEventFields $W $x $y] break
set node [$tree index @$x,$y]
set col [$tree columnindex @$x,$y]
set colname [$tree columncget $col -name]
}
O: Identifying tree column
if {$col eq "#0"}
N:
if {$colname eq "structure"}
O: Set cell valuex
$tree set $node status $status
N:
$tree cellconfigure $node,status -text $status
N2:
$tree rowattrib $node status $status
O: Set row property
$tree item $node -tags $status
N:
$tree rowconfigure $node -foreground $color($status) \
-selectforeground $color($status)
O: Get parent, identify root
set parent [$tree parent $node]
if {$parent eq ""} { return }
N:
set parent [$tree parentkey $node]
if {$parent eq "" || $parent eq "root"} { return }
O: Creating node
set id [$tree insert $node end -text $name \
-values $values]
N: For tablelist $name is part of $values
set id [$tree insertchild $node end $values]
N2: Also fill in rowattribs
$tree rowattrib $id type $type
$tree rowattrib $id status unknown
O: Tree column name is a row attribute in treeview
$tree item $id -text $name/
N:
$tree cellconfigure $id,structure -text $name/
