#12 Problem with interface port editing

[Gilles Duboscq]

When i click on the drop-down/list-box to set the number of wires for a port I get this error:

bad window path name ".dblist"
bad window path name ".dblist"
while executing
"grab set $w"
(procedure "dialogWait" line 13)
invoked from within
"dialogWait .dblist -dosync 0"
(procedure "Dropbox::showlist" line 32)
invoked from within
"Dropbox::showlist $w"
(procedure "Dropbox::press" line 10)
invoked from within
"Dropbox::press .edport.box.bit"
(command bound to event)

This happens either in the Port Properties dialog that pops-up after a right-click+add input/output
Or when using the Port List in the Interface tab

In fact this applies to all dropbox elements in the UI

Having the same problem

The proposed solution is in the default branch at https://bitbucket.org/starling13/tkgate .
It changes the behaviour of drop-down lists, which are disappeared after mouse pointer leaves it and need to be discussed.

Here is the patch:

-    bind $w_top <Configure> { destroy .dblist }
+    bind .dblist <Leave> { destroy .dblist }
     bind .dblist <Button-1> "Dropbox::listdnaction $w %W"
     bind .dblist <ButtonRelease-1> "Dropbox::listupaction $w %W"
     bind .dblist <Enter> "Dropbox::didEnter $w"

The problem is in that on Cygwin the top-level window is reconfigured many times while
drop-down box is being created and displayed, but on linux (at least) it is reconfigured only after window changes its size or positioning.
