Check grids in the document:

[Shulipa Bernad]

Hello everyone!
Friends I need to open a dialog window with a ckekbox, however, it is necessary to check if in the current document it has grids, if it is true, the chekbox has a true validation "cb1.value = true;". Serial possible? Thanks.

dlg = new Window("dialog"); 
cb1 = dlg.add("checkbox", undefined, undefined, {name: "cb1"}); 
cb1.text = "Checkbox"; 
cb1.value = false;
dlg.show();

cb1.value = activeDocument.guides.length 

?

Hi DmitryEgorov , I need to check "grids" not guids

You will most likely need to use Action Manger javascript coded to get some action reference to check the toggle state of menu View>Show>Grid shortcut Ctrl+' I don't know how to code that. Perhaps R-bin will help.

Once you know the toggle state you can toggle the state if you need to.

function ToggleGrid() {
    var dialogMode = DialogModes.NO;
    var desc1 = new ActionDescriptor();
    var ref1 = new ActionReference();
    ref1.putEnumerated(app.charIDToTypeID('Mn  '), app.charIDToTypeID('MnIt'), app.charIDToTypeID('TgGr'));
    desc1.putReference(app.charIDToTypeID('null'), ref1);
    executeAction(app.charIDToTypeID('slct'), desc1, dialogMode);
};

Thanks for the support JJMack  .I confess that it is very difficult for us to find a code that checks the current status of this command.

Its in the Adobe manual but is greek to me

Menu selection commands return an empty descriptor. We do not know state of menu item before executeAction command and after. We can only switch it.
