如何在QML中编写条件导入语句? [英] How to write conditional import statements in QML?

问题描述

就像我们在C ++中有预处理器指令一样，它可以用于条件包含.

Like we have preprocessor directives in C++ for conditional includes.

类似地，如何在QML中进行条件import?

Similarly, how to do conditional importing in QML?

if x  
    import ABC 1.0

推荐答案

根据您要实现的目标，可能的解决方法是使用加载程序.但是它不导入模块，而只是允许动态选择要使用的QML组件.

Depending on what you want to achieve, a possible workaround is to use a Loader. But it does not import a module, it just allows to choose dynamically which QML component you'll use.

Loader
{
    source: condition?"RedRectangle.qml":"BlueRectangle.qml"
}
