Hello :)
I've done a testCase with the GUI Recorder where I insert a hook on the
package explorer view.
I've downloaded the Ali Mehregani's codes (cf. the
" http://dev.eclipse.org/newslists/news.eclipse.tptp/msg01854. html" news to
know more - very usefull) to get access to the controls located in this
hooked View (the packageExplorer view), and particularly a tree (likely a
TreeViewer).
I've noticed that I can't get control on all the children of the tree in
my code if it isn't fully expanded (am I right or do I need sleep? :p). To
resolve the problem I just add a recursive method to perform a
setExpanded(true) on each tree item.
Surprisingly, it works but just a bit...
The tree is expanded but the expanded items don't show up!
I've somthing like this:
** initial state -, for ex. fully collapsed but it doesn't matter: **
+MyTreeRoot
** I perform the setExpanded)true) through my verification hook and I get
: **
-MyTreeRoot
|_ << nothing
** instead of (for example): **
-MyTreeRoot
|_FirstChild
| |_file1
|
|_SecondChild
The weird thing is that if I "physically" click on the +MyTreeRoot to
expand it, it perfectly works...
I was wondering if it was due to the cast I made on my tree component (I
did a cast from "Control" to "Tree") because I suppose that the tree in
this view is a TreeViewer.
If someone has a beginning of solution... Cheers
Bertrand.
