BWidget Tree double-click
|

| Hi,
Until now, the program shows the Tree widget with one file of my home
folder on each node (like a tree file explorer).
How can I make something happend when I double-click a node?
I didn't find information about doing this on the official
documentation.

It is I'm sure. I'll give you a snippet out of a tree editor I've
developed in the past. Assuming the tree widget is stored in 'wTree' you
will bind the double-click to the tree:
$wTree bindText <Double-1> "nodeRename $wTree $wProc"
$wTree bindImage <Double-1> "nodeRename $wTree $wProc"
## The bind procedure is then called with the selected (double-clicked)
node appended as last parameter
proc nodeRename { tree wdata node } \
{
global lastNode currentNode currentType currentName status
## Save current edited text
if {$currentNode != ""} {
set value [$wdata get 1.0 end]
set value [string range $value 0 [expr [string length $value] - 2]]
$tree itemconfigure $currentNode -data [list $currentType
$currentName $value]
}
## Get selected item
set nData [$tree itemcget $node -data]
set nType [lindex $nData 0]
..................
Hope you find it useful.

It now reads:
> $wTree bindText <Double-1> "nodeRename $wTree $wProc"
> $wTree bindImage <Double-1> "nodeRename $wTree $wProc"
As a note, doing both a bindText and a bindImage call upon the same Tree
does not work as expected; the latter call overrides the former. (See
http://tinyurl.com/p38fs for bug report.) With the forthcoming BWidget
1.8 you may want to use bindArea instead.
