Hi Luca,

To implement the deselection functionality on the ‘CheckBoxTree’ component, you can use the ‘SelectedNodes’ property to dynamically manage the selection state of the nodes.

Below is a code snippet demonstrating how to deselect all the nodes:

app.Tree_2.SelectedNodes = '';

Refer to the following MathWorks Documentation to learn more about ‘SelectedNodes’ property: https://www.mathworks.com/help/releases/R2024b/matlab/ref/matlab.ui.container.checkboxtree.html#mw_b3759bc1-1118-4512-8d8a-4c51ee96beda

I hope this helps!

HI. I think that selected mode refers to the last one selected..But in my Node (as in the photo) I have several children to deselect. However it doesn't work

In checknode I see node with flag....In selectednode No

[Walter Roberson]

app.Tree_2.SelectedNodes = [];

looks like it would work, but I am not certain that

app.Tree_2.SelectedNodes = '';

would work.

Hi @Luca Re

Do you want to deselect the checked boxes like 'Static' and 'MainStrum'?

[Luca Re]

i want to remove flag in all children....Static..MainStrum and all the others flagged

[Luca Re]

@Walter Roberson No..using selected deselects only the last selected one (but does not remove the flag if it has it)

[Luca Re]

@Sandeep Mishra excuse me..i used word "deselect" not correctly..i want to remove flag in all children

[Sandeep Mishra]

@Luca Re

To uncheck all the boxes in 'Tree_2' CheckBoxTree, you can use the following code:

app.Tree_2.CheckedNodes = []
