public void ShowAsDropDown (Rect buttonRect, Vector2 windowSize);


buttonRectウィンドウの位置からボタンが決定されます (Descriptionを参照)。



The window is styled in the same way as a PopupWindow, which means the window is automatically closed when it loses focus, and has no frame around the edge. Note this function auto-fits the window to screen while trying to place it first below then above the button it was triggered from. This means the windowSize might change when fitting it to screen, so you should make sure you read the 'position' afterwards to check whether the size was cropped.
