Like a global Settings panel that can be opened by a button in the main UI, or a button on the Effects page, or a button on the Arpeggiator page.

@Yannrog is this what you're trying to do? If so, something like this will work:

const pnlSettings = Content.getComponent("pnlSettings");
const btnSettings = Content.getAllComponents("btnSettings");

for (b in btnSettings) b.setControlCallback(btnSettingsControl);

inline function btnSettingsControl(component, value) {
	if (value) {
		for (b in btnSettings) {
			if (b != component) b.setValue(0);
		}
	}

    pnlSettings.showControl(value);
}

Your buttons can be btnSettingsMain, btnSettingsEffects, etc.

Or, simpler: btnSettings1, btnSettings2, etc. as long as they all start with btnSettings

Same code, but fully commented, in case it helps:

# Find the panel you want to show/hide
const pnlSettings = Content.getComponent("pnlSettings");

# Find all the buttons that need to toggle the panel:
# btnSettingsMain, btnSettingsEffects, etc.
const btnSettings = Content.getAllComponents("btnSettings");

# Set the function that is called when any of the buttons are clicked
for (b in btnSettings) b.setControlCallback(btnSettingsControl);

# The function that shows/hides the panel when a button is clicked
inline function btnSettingsControl(component, value) {
    # If the button is clicked 'on', turn off all the other buttons
	if (value) {
        # Check every button in btnSettings
		for (b in btnSettings) {
            # If it's a different button, turn it off
			if (b != component) b.setValue(0);
		}
	}

    # Set the panel visibility to the value of the button:
    # Button on gives value of 1, which shows the panel
    # Button off gives value of 0, which hides the panel
    pnlSettings.showControl(value);
}

Thank you

Think like this for panel names, pnlPage0, pnlPage1, pnlPage2, etc.

Buttons below and panels switching above. It would be easier.

However the name of the buttons are specific to the panel

Is it possible without a loop?

Thank you for your response, wow this is great. Ok, can the second part be done. If any of them is 1,

show the panel?

There are different ways to do this depending on how your project is set up and how you want things to behave.

The simplest is to have a single callback function applied to all the buttons. Then in the callback you can check the value of all the buttons, if any of them are 1 you show the panel.
