Re: Checkbox tree component
Hi guys, I've been fighting with trees for a week now and nearly have it doing what I require. However there is one thing I can't figure out. -My tree is build using data from an external source. -When I click a checkbox in the tree my tree model is completely restructured based upon data from an external source. -The tree is rebuilt from the root node downwards and the treemodel updated via a call to it's setRoot() using the new root as the argument. What I want is for the node that was checked to stay checked, that is, persist across the tree update. This obviously happens by default, that is, without rebuilding the from the root node, but I don't know how to update the tree without doing that. Any ideas? -- View this message in context: http://www.nabble.com/Checkbox-tree-component-tp13433102p23098936.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Re: Checkbox tree component
Hey Doug, I was able to get the check boxes to work. Thanks for your help on that. However there is another problem that I am not able to get to work. I have created another panel with a checkbox tree in it and i want that panel to show only when I check one of the child nodes in my main checkbox tree. i.e. I have Panel1 and Panel2 for a page both having a checkbox tree component in them say checkboxtree1 and checkboxtree2 respectively. I want the Panel2 to show up (along with the tree) only when a node of the checkboxtree1 is selected. I tried to add the panel dynamically in the onNodeCheckUpdated() method of the main panel but it doesn't work like that. Any ideas about how i can get this to work.

Re: Checkbox tree component
I am sure there are a couple of ways to do this.
First thing that comes to mind is to override the Panel2.isVisible() method
and return true if there are any nodes selected in CBTree1.
for instance:
Panel checkBoxPanel2 = new Panel( checkBoxPanel2 ) {
public boolean isVisible() {
return /** cbTree1 Selection State **/;
}
};
To determine the cbTree1 Selection State, either you iterator through the
entire tree to determine if a node is selected via the TreeState or capture
the number of nodes selected/deselected via TreeStateListener.
By overridding isVisible(), no matter if you are refreshing the entire page
or via Ajax, the checkBoxPanel2 visibility would be handled correctly.
Hope that helps.
- Doug

Re: Checkbox tree component
Hey Doug, I am fairly new to wicket. I am trying to use the checkbox tree component and it seems to be working well. However I would like to check or uncheck all the child nodes if the parent node is selected(i.e. if the check box in front of the parent node is checked or unchecked). Kindly let me know how can I implement that. Thanks, vishy_sb Doug Leeper wrote: Ok here it is. I have also included my use of it.

Re: Checkbox tree component
It depends. Are you building the entire tree up front or are you building the child nodes dynamically (i.e. when the parent node is selected/expanded)? -- View this message in context: http://www.nabble.com/Checkbox-tree-component-tp13433102p18147561.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Checkbox tree component
Well currently I am testing the tree using a model which creates the entire tree up front... however for the final implementation I would be building the child nodes dynamically hence I guess I would be using both of them Thanks for the quick reply Doug Leeper wrote: It depends.

Re: Checkbox tree component
Doug, great work! Can I just ask you a question, what does your implementation of the CategoryTreeModel look like? I've been trying all sorts of approaches for doing a similar category tree but I've never liked / got the model approach to work in a nice fashion. :) /Regards Mats On Oct 27, 2007 6:04 AM, Doug Leeper [EMAIL PROTECTED] wrote: Ok here it is.

Re: Checkbox tree component
Hello All! This CheckBox tree is very cool. But I'm having some strange interactions with the web server: when I run under Jetty everything goes smoothly, but when I deploy to tomcat, I get a bunch of unrendered component exceptions for the component with id checkbox and whose class is some deeply nested anonymous inner class. Does anyone have any idea what could possibly be the difference between the two containers? I believe that I'm running with servlet-api-2.5 in both Jetty and Tomcat. My web.xml has version=2.5 in its webapp tag. I'm not getting unredered component complaints for anything else anywhere in my site. I'm totally baffled. Any help would be greatly appreciated, Ciao, Ben. -- View this message in context: http://www.nabble.com/Checkbox-tree-component-tf4699092.html#a14184918 Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Checkbox tree component
Has anyone put together a checkbox tree component? I've done some searches but haven't turned anything up. Basically, I'd like a tree with a checkbox leading each node that when checked also selects all child nodes. I'm thinking of something like the tree you see when you do software updates in Eclipse: http://www.nabble.com/file/p13433102/Clipboard01.jpg The component would provide a method for getting all the selected nodes.
