Hi, in my WebApp I use a GWT Tree. I have made a Button, when you klick
this button the whole tree should be expanded / closed.
But when I click the button sometimes a TreeItem does not close. When I
debug this I can see that the open state is not changed but I called the
method treeItem.setState(open).
So I don't know why this isn't changed in my TreeItem.
Any suggests ?
Thanks in advance.
Here is my onClick Method:
* public void onClick( ClickEvent event )*
* {*
* Object source = event.getSource();*
* if ( source.equals( getView().getButtonBaumEinAusKlappen() ) )*
* {*
* for ( int i = 0; i < getView().getTree().getItemCount(); i++ )*
* {*
* TreeItem myTreeItem = getView().getTree().getItem( i );*
* if(myTreeItem.getChildCount()>0)*
* getView().getTree().expandAll( myTreeItem, !expandState );*
* myTreeItem.setState( !expandState );*
* int andkw = 5;*
* }*
* expandState = !expandState;*
* }*
*}*
and here is my epandAll method:
* public void expandAll( TreeItem item, boolean expand )*
* {*
* for ( int i = 0; i < item.getChildCount(); i++ )*
* {*
* // do action here*
* TreeItem childTreeItem = item.getChild( i );*
* childTreeItem.setState( expand );*
* // recursive call for current node.*
* expandAll( childTreeItem, expand );*
* }*
* }*
