public class JFileChooser extends JComponent implements Accessible
Emulator for JFileChooser. Emulator-only host (no surrogate): showOpenDialog composes an internal modal JDialog hosting a Vaadin Upload, parks the calling virtual thread via the JDialog modal machinery, and returns APPROVE_OPTION / CANCEL_OPTION once the user uploads + confirms (or cancels). showSaveDialog picks a name, hands back a per-session temp target via getSelectedFile(), and opens the synthetic download affordance. Selection getters return java.io.Files pointing at per-session temp files. Transfer mechanics are shared with FileDialog via BrowserFileTransfer.

      @Deprecated public int showDialog(Component parent, String approveButtonText)
      Deprecated.
      triage the call site to showOpenDialog(Component) (the app reads the file) or showSaveDialog(Component) (the app writes it) — setApproveButtonText(String) keeps the custom label. The deprecation is deliberate divergence from the JDK, and is what makes an untriaged call site visible at compile time rather than only when someone walks that path.
      Unsupported in the browser, always throws — the sole throw on this class (R_match_swing_errors throw-trigger case (4), D_showdialog_throws). CUSTOM_DIALOG declares no LOAD/SAVE direction, and the two are different browser mechanisms that must be committed before the dialog opens, so no default is defensible: mapping it to LOAD silently produces an unreachable file whenever the app was naming an output. Nothing is mutated before the throw — the call is a no-op plus an exception. setDialogType(CUSTOM_DIALOG) itself stays faithful and round-trips; only the show is refused.
      Throws:
      IllegalStateException - always, carrying the triage rule.

      public void setAccessory(JComponent newAccessory)
      Parameters:
      newAccessory - the accessory component. Typed vaadinx.swing, not javax.swing: the JDK declares this signature, so per R_no_vaadin_in_api limb 1 it must speak the emulator's types. It took the JDK type until D_reverse_fanout_rows, which made the method impossible to call from import-swapped code at all — a migrator's JPanel is a vaadinx.swing.JPanel.
