Hello everobody,

I have build a Window with a TreeView and 2 radio buttons.

1 radio button to expand all nodes // 1 radio button to collapse all nodes

OnClick on each radio button called a specific recursive function that expand or collapse my tree : 

// Expand all treeview nodes 
function expand_tree(my_treeview){
    my_treeview.expanded = true;
    var branches = my_treeview.items;
    for (var i = 0; i < branches.length; i++) {
        if (branches[i].type == 'node') {
            expand_tree (branches[i]);
        }
    }
}
// Collapse all treeview nodes 
function collapse_tree(my_treeview){
    my_treeview.expanded = false;
    var branches = my_treeview.items;
    for (var i = 0; i < branches.length; i++) {
        if (branches[i].type == 'node') {
            collapse_tree (branches[i]);
        }
    }
}

 

expand_tree function expand all nodes into my tree

But, collapse_tree function seems to do nothing…

I think my_treeview.expanded = false is the problem. 

I test it with my_treeview.collapsed = true but unsuccessfully

Do you have any idea ?

Thank you

Hi Stéphane,

think, we are still lucky with tree view and InDesign.

With PhotoShop it's not available anymore since Flash was removed:

 

February 15, 2017

Photoshop UI toolkit for plug-ins and scripts

Known issues

 

The Flash Player widget is no longer supported. It is not possible to play SWF/Flash/Flex files through the script UI any longer.
Treeview widget is not supported.
Graphics drawing is not supported on Checkbox and Radiobutton widgets.
Button background color cannot be changed.
Font styles on text are not supported

Hi,

 

I cannot see any obvious problem, are you able to share your whole project so that we have a place to start from?

 

Regards
