Qt Creator plugin动手实践（1）学习基本构成

Qt Creator plugin

如果把D:\Qt\Qt5.9.8\Tools\QtCreator\lib\qtcreator\plugins\路径下的文件全部删除（只保留Core4.dll文件），然后再启动，那么Qt Creator就变成这样了，简直就是个空壳子：

可见Qt Creator这个庞然大物是由各类插件构成的！把插件拿掉，它就只是一张皮了。

Qt Creator 源码学习

开源项目参考：

https://github.com/lexxmark/QtCreator-JsExtensions-Plugin https://github.com/pasccom/QtcDevPlugin https://github.com/MichaelSp/QtCreator-Jenkins-Plugin https://github.com/Eaknyt/QtCreator-ColorPickerPlugin

Qt5：

qtdesigner的源码在Qt Creator源码里面，以插件形式出现

https://github.com/qt-creator/qt-creator/tree/master/src/plugins/designer

Qt4：

Qt Creator源码里面是没有设计器的实际的代码的，它使用的是QtDesigner.dll。

qtdesigner的源码在qtsdk中。

以qt4.8源码为例：qtdesigner.dll的源码路径为\tools\designer\src
