Qt Creator plugin動手實踐（1）學習基本構成

Qt Creator plugin

如果把D:\Qt\Qt5.9.8\Tools\QtCreator\lib\qtcreator\plugins\路徑下的檔案全部删除（隻保留Core4.dll檔案），然後再啟動，那麼Qt Creator就變成這樣了，簡直就是個空殼子：

可見Qt Creator這個龐然大物是由各類插件構成的！把插件拿掉，它就隻是一張皮了。

Qt Creator 源碼學習

開源項目參考：

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的源碼在Qt Creator源碼裡面，以插件形式出現

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

Qt4：

Qt Creator源碼裡面是沒有設計器的實際的代碼的，它使用的是QtDesigner.dll。

qtdesigner的源碼在qtsdk中。

以qt4.8源碼為例：qtdesigner.dll的源碼路徑為\tools\designer\src

https://github.com/qt/qt/tree/4.8/tools/designer 個人筆記：2019/4/19，摘錄于Qt Creator源碼
