Qt虚拟键盘[PyQt 5.8]-找不到样式，无法调整虚拟键盘的大小

我一直在尝试使用Qt虚拟键盘，并且一直运行得很好。

问题是：

1. 设置环境变量。
2. QT_VIRTUALKEYBOARD_STYLE（未找到）。我已经从另一个stackoverflow帖子中创建了自己的样式，看起来不错，但是没有找到。

警告：Cannot find style ".../INTERACT/interact-ii/tools/en_GB/customkb.qml" - fallback: "default"

一些尝试：

1. 已经将customkeyboard.qml单独文件放在我自己的项目中，并将变量设置为其路径。
2. 修改后，将整个文件夹“ en_GB”从项目中的默认Qt文件夹中放入。
3. 还使用我的样式将变量设置为Qt文件夹中的原始路径。
4. 下载了Qt 5.8 / 5.7 / 5.6，并对所有qtvirtualkeyboard进行了相同的操作。
5. 看到上述错误（备用：“默认”）后，我尝试将qml项目从qt文件夹添加到default.qml。[... / Qt / 5.8 / Src / qtvirtualkeyboard / src / virtualkeyboard / content / styles / default]
6. 用QTCreator打开了qtvirtualkeyboard.so文件，并在更改我的qml文件后构建了所有文件，以查看它是否可以更改某些内容，并且没有任何更改。

他们似乎都没有修改我的键盘大小和位置。

以下是一个重要示例的文件。

问题：

我在设置STYLE和LAYOUT变量方面做错了吗？我应该真正设置这两者中的哪一个，是STYLE还是LAYOUT变量会改变键盘的大小和位置？我应该在哪里真正放置qml文件？我究竟做错了什么？看不出是什么问题！！

我相信您会混淆样式的布局，这会给您带来一些问题。

布局（Layouts）

1. en_GB目录中的.qml文件是Qt用于键盘布局的文件。
2. 要包含自定义布局，必须将QT_VIRTUALKEYBOARD_LAYOUT_PATH变量指向为自定义布局创建的目录（例如QT_VIRTUALKEYBOARD_LAYOUT_PATH = /path/to/custom/keyboard-layout/mycustomlayout）。然后，要添加英式英语的自定义布局，您将在/path/to/custom/keyboard-layout/mycustomlayout中创建一个en_GB目录。在您的en_GB目录中，至少应具有main.qml。
3. 您已将文件命名为customkeyboard.qml。为了让Qt来正确定位，加载和处理您的自定义布局，您必须遵循默认布局（即main.qml，handwriting.qml，symbols.qml）的文件命名约定，作为参考这里。

样式（Styles）

对于自定义样式，您必须将自定义样式目录放在$$[QT_INSTALL_QML]/QtQuick/VirtualKeyboard/Styles中，如此处所述。显然，您的自定义style.qml文件位于自定义样式目录中。

希望这可以帮助您澄清一些事情。

为了澄清起见，QT_VIRTUALKEYBOARD_LAYOUT_PATH应将其设置为en_GB的包含文件夹。为了确认您已经为布局正确设置了所有设置，我只需要交换前两个键main.qml（例如，用“ W”代替“ Q”），以验证Qt是否正在使用您打算操纵的布局。在中定义位置，大小等style.qml。这个文件应该被放置在$$[QT_INSTALL_QML]/QtQuick/VirtualKeyboard/Styles/YourCustomStyleNameGoesHere/style.qml与QT_VIRTUALKEYBOARD_STYLE设置为$$[QT_INSTALL_QML]/QtQuick/VirtualKeyboard/Styles/YourCustomStyleNameGoesHere
