It display the bitmap charged in its Glyph property, or if this property is empty, it becomes an active transparent zone to place at the top of Bitmap to define several hot zones for example. Supports PopUp Menus, three-state bitmaps, etc. TXFoldButton - Identical to TXStatiButton but with the possibility of unfolding itself and to fold up itself on him even by adjusting the size of his parent control (generally TPanel). When the button is folded up it's possible to hide the Parent controls and when it's unfolded to display them (like the left button of the Netscape 4.x toolbar). 和TSpeedButton相同的按钮TXStaticButton ,和TXStatiButton 相同的按钮TXFoldButton
