check if a group is open or closed

[Ciccillotto]

I have a small problem
I need to know if a group is open or closed
I put up a small script in uxp
but it tells me that the group is always open even if it is closed,
this is the script.

checkLayerGroupStatus()

async function checkLayerGroupStatus() {
    const layers = app.activeDocument.layers;
    const groupName = "Color"; 

    const layerGroup = layers.find(layer => layer.name === groupName && layer.layers);
    if (!layerGroup) {
        showAlert( `Level group "${groupName}" not found`);
        return;
    }

    const isOpen = layerGroup.visible;
    if (isOpen) {
        showAlert(`The level group "${groupName}" is open.`);
    } else {
        showAlert( `Level group "${groupName}" is closed.`);
    }
}

Is »visible« not the Layer Visibility which is unrelated to whether a Group is open or not? 

[Ciccillotto]

even if I remove visible the problem remains.

[c.pfaffenbichler]

Not what I meant. 

»visible« seems to refer to the Layer’s/Group’s visibility, so where is the property that describes whether a Group is expanded?

[c.pfaffenbichler]

@DBarranca , please forgive the intrusion. 

Do you know whether in UXP Scripting Groups have a property that indicates whether they are closed or expanded in the Layers Panel? 

[Ciccillotto]

I haven't found anything about it, I hope Barranca passes by this post.

c.pfaffenbichler How could the same thing be with javascript. I'll see if I can adapt it.

As far as I can tell ESTK Scripting does not provide a property for determining that. 

There have been work-arounds to open and close a Group but those were less than elegant.

It seems that layerSectionExpanded is the property being sought. Get it via batchPlay.

Found also an ExtendScript version.

• Collapse single group of layers

Dang, fully missed that one! 

[Ciccillotto]

Thank you for your help but I couldn't solve it.

[sttk3]

What is the reason for that?

[c.pfaffenbichler]

Dang again! 

As the property worked fine in ESTK Scripting I assumed the UXP samples @sttk3 linked to would work out for you.

Verified that it works with this UXP script.

@sttk3
wonderful
I wasted two days trying to figure out how to fix the problem
but I couldn't
thank you so much for your help

[sttk3]

In other words, the problem was solved by my code, correct?

[Ciccillotto]

Yes your code is perfect. Thank you with all my heart.
