How to change options in Preferences

Great request, @SeanH.
As has already been discussed elsewhere, we cannot at the moment support the Eucon protocol since it would probably involve reverse engineering or getting licensed by Avid (and since that would compete with their consoles I don't see that happening).
However, we could automate opening the Prefs dialog and click checkboxes. Usually the GUI automation is pretty quick so it would may be barely noticeable - and I guess lots of functions could benefit from being able to set prefs.
Would that kind of solution be usable to you?

I'm trying to adapt the function to toggle the Audio Files checkbox in the 'Save Copy In...' window in pr tools but I'm also getting the error "CheckBoxAction requires UIElement (Checkbox Action)"

Any chance you can see where I'm going wrong?

function setPrefCheckbox(groupName, checkboxName, targetValue) {
    var prefsWin = sf.ui.proTools.windows.whoseTitle.endsWith('Save Copy In...').first;

    //Find group
    var group = prefsWin.groups.whoseTitle.is(groupName).first;

    //Find CheckBox and set it
    var checkbox = group.checkBoxes.whoseTitle.is(checkboxName).first;
    checkbox.checkboxSet({
        targetValue: targetValue
    });
}
setPrefCheckbox('Items To Copy', 'Audio Files', 'Enable');

Thanks yet again,
Dustin

EDIT

nevermind, it was way easier than I thought.

sf.ui.proTools.windows.whoseTitle.is('Save Copy In...').first.checkBoxes.whoseTitle.is('Audio Files').first.checkboxSet({
    targetValue: "Enable",
});

Also, what's the right way to wrap code on this forum so it shows up with the proper formatting?

Hey all. I'm trying to use that code @chrscheuer has up there to change color coding of clips. Problem is there are 2 buttons named "Tracks and MIDI Channels". I want to change the second one and not the first one as I'm trying here but getting an error.

function openPrefs() {
    sf.ui.proTools.appActivateMainWindow();

    //Open up Preferences
    sf.ui.proTools.menuClick({ menuPath: ['Pro Tools', 'Preferences...'] });

    //Wait for Preferences window to appear
    var prefsWin = sf.ui.proTools.windows.whoseTitle.endsWith('Preferences').first;
    prefsWin.elementWaitFor();
}

function setPrefCheckbox(tabName, groupName, checkboxName, targetValue) {
    var prefsWin = sf.ui.proTools.windows.whoseTitle.endsWith('Preferences').first;

    //Choose tab
    prefsWin.children.whoseTitle.startsWith(tabName).first.elementClick();

    //Find group
    var group = prefsWin.groups.whoseTitle.is(groupName).first;

    //Find CheckBox and set it
    var checkbox = group.checkBoxes.whoseTitle.is(checkboxName).first;
    checkbox.checkboxSet({
        targetValue: targetValue
    });
}

function setPrefRadioButton(tabName, groupName, radioButtonName) {
    var prefsWin = sf.ui.proTools.windows.whoseTitle.endsWith('Preferences').first;

    //Choose tab
    prefsWin.children.whoseTitle.startsWith(tabName).first.elementClick();

    //Find group
    var group = prefsWin.groups.whoseTitle.is(groupName).first;

    //Find RadioButton and click it
    group.radioButtons.whoseTitle.is(radioButtonName).first.elementClick();
}

function setPrefRadioButton2(tabName, groupName, groupName2, radioButtonName) {
    var prefsWin = sf.ui.proTools.windows.whoseTitle.endsWith('Preferences').first;

    //Choose tab
    prefsWin.children.whoseTitle.startsWith(tabName).first.elementClick();

    //Find group
    var group = prefsWin.groups.whoseTitle.is(groupName).first;
    var group2 = group.groups.whoseTitle.is(groupName2).first;

    //Find RadioButton and click it
    group2.radioButtons.whoseTitle.is(radioButtonName).first.elementClick();
}

function closePrefs() {
    //Click OK
    var prefsWin = sf.ui.proTools.windows.whoseTitle.endsWith('Preferences').first;
    prefsWin.buttons.whoseTitle.is("OK").first.elementClick();

    //Wait for Preferences window to close
    prefsWin.elementWaitFor({ waitForNoElement: true });
}

//Here you set your preferences:
openPrefs();
setPrefCheckbox('Display', 'Color Coding', 'Always Display Marker Colors', 'Enable');
setPrefRadioButton('Display', 'Color Coding', 'Track Color');
setPrefRadioButton2('Display', 'Color Coding', 'Default Clip Color Coding', 'Tracks and MIDI Channels');
closePrefs();

How do I define that radio button under "Default Clip Color Coding" without changing the one by the same name under "Default Track Color Coding"?

Thanks.
