Yuriy – I do not understand your question

@Paul – you can check each node’s SelectionState property value, and you can compare it to com.mathworks.mwswing.checkboxtree.SelectionState.SELECTED, .NOT_SELECTED or .MIXED. For example:

if jRoot.getSelectionState == com.mathworks.mwswing.checkboxtree.SelectionState.NOT_SELECTED, ...

I am using the Matlab built in class (com.mathworks.mwswing.checkboxtree.CheckBoxTree), how do I get a list of which nodes have the check box marked?

If I use:

jCheckBoxTree.getSelectionPaths()

…from the built-in class example I get a list of the highlighted nodes, not the checked ones.

-Thanks

… found a solution:

set(nodeFile(qq),'SelectionState',SelectionState.SELECTED);

However, this unfortunately does not update the parent selection boxes. Is there any method to re-validate the whole selection state of the jtree?

Thanks so much!

this is an incredibly cool resource as all your stuff.

I’m using the com.mathworks.mwswing.checkboxtree.DefaultCheckBoxNode and would like to set the state of the check boxes programmatically.

I know the getSelectionState property that works fine for me.
However, setSelectionState method does not:

>> jBox.setSelectionState(true)
No method 'setSelectionState' with matching signature found for class 'com.mathworks.mwswing.checkboxtree.DefaultCheckBoxNode'.

Any ideas?
Thanks so much!

@KhRaIf – there are several ways in which you can speed up your Matlab code. In general, you need to run the Profiler and see where the performance hotspot is, and try to optimize that. One general idea that could help is to create the tree model first, and only then to attach it to the tree, rather than updating a visible tree one node at a time (which is much slower since the tree needs to refresh after each update). Also, updating an invisible tree is faster than a visible one – you can make it visible when it is ready.

If you still need additional assistance, email me for private consulting.

@Daniel – try to use the parent’s Children property, as in: numel(hParent.Children)

@ACenTe – this would probably require creating a custom CellRenderer class in Java. Email me for private consulting on this if you are interested.

I have a question regarding the uitree/uitreenode and if it is possible to speed up the process. I have built my tree using uitreenode, and the user can have several filters. Because I have more then 1e4 elements, it takes quite a while filter everytime. For the time being, I do it using the following workflow:

for k=1:NumberOfElements
   Check_if_Filter_Satisfied;
   New_Node = uitreenode;
   MyTree.add = Node ;
end

this is taking too much time.
Is there a possibility to speed up things? Maybe by extracting a small tree from a larger tree?
Thanks in advance,
