TR - I saw that the combobox of the Tile package didn't support autocompletion, so I added it using the code from BWidget:
proc ComboBoxAutoComplete {path key} {
#
# autocomplete a string in the ttk::combobox from the list of values
#
# Any key string with more than one character and is not entirely
# lower-case is considered a function key and is thus ignored.
#
# path -> path to the combobox
#
if {[string length $key] > 1 && [string tolower $key] != $key} {return}
set text [string map [list {[} {\[} {]} {\]}] [$path get]]
if {[string equal $text ""]} {return}
set values [$path cget -values]
set x [lsearch $values $text*]
if {$x < 0} {return}
set index [$path index insert]
$path set [lindex $values $x]
$path icursor $index
$path selection range insert end
}All you need to do now, is binding <KeyRelease> to this procedure:
package require Tk 8.5 package require tile ttk::combobox .c -values [list one two three four five six seven] pack .c -padx 5 -pady 5 bind .c <KeyRelease> [list ComboBoxAutoComplete .c %K]
CLN 2006-04-20 - Shouldn't this be in a namespace or at least be named ttkComboBoxAutoComplete? For that matter, why not submit a patch to get this into the Tile distribution. (Not that I wouldn't be grateful to have it available here in the mean time if I was using Tile.)
TR 2006-04-21 - I just read the tile paper [L1 ] by Rolf Ade. It mentions autocompletion code in the demos directory of the tile distribution. I haven't used that code yet, but it seems to do the same job as the code above, just in the correct namespace and as a command like
tile::combobox::enableAutocomplete
So, the above code is not needed, really ...
RLH It would be nice if a widget is involved to see a graphic showing the widget. Not necessary...but nice.
D. McC 2008 Dec 8: OK, after rummaging through the ttk::style man page and trying things out in vain, I give up. Can somebody tell me how to specify the background color for the entry portion of the ttk::combobox? And can somebody tell me why there is not even an option to specify colors of Ttk widgets in the same ultra-simple way as for Tk widgets, e.g., "-bg AntiqueWhite"?
Bryan Oakley 2008 Dec 8: To solve your immediate problem, try this:
ttk::combobox .cb -style mycombobox.TCombobox ttk::style configure mycombobox.TCombobox -fieldbackground bisque
(using "ttk::style map" may be a better choice, but I'll leave that as an exercise for the reader)
As to why there is no option, that's the design philosophy of the themed widgets -- you lose some amount of control over individual widgets but gain the ability to create unified themes.
D. McC 2008 Dec 9: Thanks--it works! Now I'll see about incorporating that into my color-scheme files.
What I still don't understand is why the programmer isn't given a choice about how much control over individual widgets (and ease of configuring them) to trade off for how much ability to create unified themes.
TLT 2009-11-28 - I was annoyed that the ttk::combobox does not change the cursor to an ibeam when it is inside the text entry widget. The following binding fixes that:
bind TCombobox <Motion> {
if {[%W cget -state] eq "normal" && [%W identify %x %y] eq "textarea"} {
%W configure -cursor xterm
} else {
%W configure -cursor ""
}
}
pack [ttk::combobox .cb]
