VGScene 学习日志一：关于TvgScene设置为透明后，里面的按钮不能点击的问题记录

因工作需要，今天开始研究Delphi开发工具下的VGScene控件，首选 介绍一下VGScene:

VGScene speeds the development of all graphical application, providing: a graphical editor integrated in IDE, graphical objects, simplify animation, advanced windows and controls, maximum performance, skinning engine, bitmap effects. VGScene can be used as development tools for SCADA, GIS, CAD and KIOSK applications.

 

• Powerful vector engine like Adobe Flash or Microsoft WPF

   

• Fast realtime anti-aliased vector graphics, resolution independent, alpha blending, gradient and special visual filling

   

• WYSIWYG design-time and run-time designer and property editors

   

• Advanced GUI engine - window, button, textbox, numberbox, memo, anglebox, list box and much much more

   

• Advanced skinning engine based on vector graphics styles. Cool exists styles - Dark, Modern, Vista, Air.

   

• VGScene provides shape primitives for 2D graphics along with a built-in set of brushes, pens, geometries, and transforms

   

• Advanced animations techniques calculated in background thread. Easy to use, accuracy, minimal CPU usage and automatic FPS correction

   

• VGScene provides for bitmap effects, however, they are rendered in software. Special effects such as dropshadows and blurring are built in.

   

• VGScene can be used as development tools for SCADA, GIS, CAD and KIOSK applications

   

• Path object have SVG, WPF path data format

   

• Very easy to use and powerful layouts. The child elements are recursively arranged by their parents.

   

• Layered forms, unicode enabled

   

• Jpeg, Png, Tiff and Gif format read/write support on Windows and Mac OS X

   

• Fast thumbnail creation and image processing

   

• Cross-platform solution available on Microsoft Windows and Apple Mac OS X

主要就是可媲美.net的WPF界面效果，跨平台，动画效果实现。目前不知道最新版本是多少了，我使用的是4.42.可以在csdn的下载里面找到我发布的安装包。

 

 

我的第一个例子其实很简单，就是在一个窗体上放置了一个TvgScene,里面创建了四个按钮对象(TvgBitmapButton）,然后通过属性编辑器设置，第一就是设置TvgScene的Transparency为true，然后设置其下的Root1的HitTest为False.

         第二就是设置四个按钮的Click事件，只是简单的弹出对话框，

当我运行里来后，窗体无边框的show了出来，但当我点击放到上面的按钮后，发现无反应，设置断点发现没有触发事件。经过和Demo仔细

对比，我才发现原来是Form窗体的BorderStyle没有设置为bsNone造成的。

       希望对同样用VgScene的兄弟们有帮助。
