引入pngimage第三方控件，可以支持 PNG 格式的图标、效果更好。 pngimage 很有意思，Delphi版包括4个pas文件（具体哪个是关键没有仔细研究）， 只要 uses pngimage 就可用 Image 来载入PNG格式的图片，很神奇，佩服作者。 增加缓冲功能 DoubleBuf，减少闪烁。 添加 Align 属性的继承，编译成控件时便于摆放。 增加控制标题文本区显示控制的属性设置 ShowCaption。 添加载入背景方法 loadBackPic。 加强整个界面拖动的效果。(Introduction pngimage third-party controls, you can support the PNG format icons, better. pngimage very interesting, Delphi Edition includes four pas file (which is the key not specifically studied), Image can be used as long as the uses pngimage to load PNG format images, it is amazing, admire the author. Increase the buffering function DoubleBuf, to reduce flicker. Add Align property inheritance, controls easy to compile into place.
