A panel groups controls and paints an optional background rectangle. Child coordinates are relative to the panel's (x,y).

Example:

panel sidebar {
  x 0; y 0; width 120; height 240; background "#F5F5F5"

  label head { x 6; y 6; text "Menu"; textColour black }

  button a { x 6; y 32; width 108; height 22; text "Home" }
  button b { x 6; y 58; width 108; height 22; text "Settings" }
}

Supported children inside a panel:

• label, button, input, image, listbox
• Panel-level properties: x, y, width, height, background.

Variables recorded for panel children mirror window ones, prefixed with panel_<panelName>_..., e.g.:

• panel_sidebar_button_a_text
• panel_sidebar_input_search_text
• panel_sidebar_listbox_items_count
