QT5.8.自定义虚拟键盘包括

Question

我正在编写一个基于QtVirtualKeyboard的定制虚拟键盘。在我的项目中，我需要能够使用我的键盘版本。

但是，我发现的唯一方法是重新编译项目，并在我的版本"qtvirtualkeyboardplugin.dll“中替换"mingw53_32\plugins\platforminputcontexts”中的原始"qtvirtualkeyboardplugin.dll“。并在qputenv("QT_IM_MODULE", QByteArray("qtvirtualkeyboard"));中使用main.cpp函数

在阅读了几个小时的文档和尝试了各种事情之后，我仍然找不到方法在本地使用自定义键盘，而不删除原始的"qtvirtualkeyboardplugin.dll“。

我假设您已经分叉了代码，在这种情况下，下面的修改似乎足以使plugins/platforminputcontexts安装一个不同名称的插件

• 将qtvirtualkeyboard/src/virtualkeyboard/qtvirtualkeyboard.json重命名为qtvirtualkeyboard/src/virtualkeyboard/customvirtualkeyboard.json。
• 在customvirtualkeyboard.json中，将qtvirtualkeyboard键重命名为customvirtualkeyboard。
• 在qtvirtualkeyboard/src/virtualkeyboard/plugin.cpp中，将pluginName字符串的内容更改为customvirtualkeyboard。
• 在qtvirtualkeyboard/src/virtualkeyboard/plugin.h中，将FILE字符串更改为customvirtualkeyboard。
• 在src/virtualkeyboard/virtualkeyboard.pro中，将TARGET = qtvirtualkeyboardplugin更改为TARGET = customvirtualkeyboardplugin。这会影响您在.dll中看到的已安装的plugins/platforminputcontexts、.lib等的名称。

下面是作为Git diff所做的更改：
