我正在编写一个基于 QtVirtualKeyboard 的自定义虚拟键盘​​。对于我的项目，我需要能够使用我的键盘版本。

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

经过数小时的阅读文档和尝试各种事情后，我仍然找不到在本地使用自定义键盘的方法，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，以下修改似乎足以将不同名称的插件安装到plugins/platforminputcontexts：

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

以下是作为 Git diff 的更改：
