Detailed Description

A ComboBox that continuously scans the local network for DS100 devices announced via Zeroconf/mDNS and lets the user select one to connect to.

Used inside the connection settings dialog (MainComponent::showConnectionSettings()), embedded via juce::AlertWindow::addCustomComponent().

When the user picks an entry, onServiceSelected fires with the resolved IP and port so the caller can populate the IP/port text editors in the same dialog.

Network discovery

Backed by ZeroconfSearcher::ZeroconfSearcher("OCA", "_oca._tcp") from the JUCEAppBasics submodule, which handles mDNS browsing on a background thread. handleServicesChanged() is called on the JUCE message thread via MessageManager::callAsync whenever the service list changes, rebuilding the combo items with entries of the form "DeviceName (ip:port)".

Layout adaptation inside AlertWindow

juce::AlertWindow::updateLayout() only calls setTopLeftPosition() for custom components — it never resizes them. If the component were left at its initial size it would overflow and be clipped whenever the dialog is narrower than that size (e.g. on narrow Stage Manager windows or small device screens).

parentSizeChanged() therefore overrides the JUCE hook that fires on each parent resize to set the component's width to 80 % of the parent dialog's width, matching the width that AlertWindow gives to its own built-in text editors and combo boxes. The initial setSize() call in the caller sets a small placeholder width (10 px) so the component does not inflate the dialog before parentSizeChanged() runs.
