QML开发炫酷中文键盘篇

(36) 2024-02-26 18:01:01

首先声明拼音是拿的谷歌源码,其次布局-界面-逻辑都是本人所写.

本键盘主要开发的功能:
1.支持任意大小写,及特殊字符的输入
2.支持中文输入
3.支持快捷选项

上图大致分为两部分{ cpp,qml }

1.abstractlistelement.cpp,abstractlistmodel.cpp这两个cpp是与QML交互拼音接口
2. 主插件:MyVirtualKeyboard.qml
3. 子插件: {

3.1 ClickedInformationModel.qml : 代理显示字符
3.2 LetterListDelegate.qml: 代理点击组件
3.3 {LetterListModel_1.qml,LetterListModel_2.qml
,LetterListModel_3.qml,LetterListModel_4.qml} : 代理键盘
3.4 MyVirtualKeyboard_js.qml : 处理界面逻辑
3.5 MyVirtualKeyboardAnimation.qml: 处理界面动画
}

主插件源码:
