Key patterns

Gui.menubarBegin()
// align=17 (0x11 = NK_TEXT_LEFT)
if (Gui.menuBeginLabel("File", 17, 120, 200)) {
    Gui.layoutRowDynamic(25, 1)
    if (Gui.menuItemLabel("New", 17)) addLog("File > New")
    if (Gui.menuItemLabel("Open", 17)) addLog("File > Open")
    Gui.separator(128, 128, 128, 60, true)
    if (Gui.menuItemLabel("Exit", 17)) addLog("File > Exit")
    Gui.menuEnd()
}
Gui.menubarEnd()

// Right-click contextual
if (Gui.contextualBegin(0, 150, 200, 0, 0, w, h)) {
    Gui.layoutRowDynamic(25, 1)
    if (Gui.contextualItemLabel("Copy", 17)) addLog("Copy")
    if (Gui.contextualItemLabel("Delete", 17)) addLog("Delete")
    Gui.contextualEnd()
}
