Emilian Bold created NETBEANS-2326: -------------------------------------- Summary: Explorer API views (ListView, TreeTableView) flicker when filtering nodes Key: NETBEANS-2326 URL: https://issues.apache.org/jira/browse/NETBEANS-2326 Project: NetBeans Issue Type: Bug Components: platform - Explorer, platform - Nodes Affects Versions: 8.2, 10.0 Reporter: Emilian Bold Attachments: dummy-nodes.png, filternode-flicker.mov
For a brief second the Explorer API views show dummy nodes for a filtered node. The children filtering is done the 'usual' way: {{}}{{new FilterNode.Children(node) {}} {{ @Override}} {{ protected Node[] createNodes(Node key) {}} {{ if (rule(key)) {}} {{ return super.createNodes(key);}} {{ } else {}} {{ //filter out}} {{ return new Node[0];}} {{ }}} {{ }}} and what happens is that the ListView / TreeTableView GUI does *not* show only the allowed nodes. It shows all the original children for a split second then it shows the filtered nodes. See the attached screenshot and video for a general idea. I'm also going to attach a small project. Oddly enough Children.Keys(boolean lazy) [http://bits.netbeans.org/dev/javadoc/org-openide-nodes/org/openide/nodes/Children.Keys.html#Keys-boolean-] does mention a "dummy" Node but it was never clear what that is and I never imagined it could go all the way to the UI. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@netbeans.apache.org For additional commands, e-mail: commits-h...@netbeans.apache.org For further information about the NetBeans mailing lists, visit: https://cwiki.apache.org/confluence/display/NETBEANS/Mailing+lists
