Question

是否有可能在NSIS安装程序自定义页面上显示一些描述性文本，但仅限鼠标悬停？

我在安装程序开头检查了先决条件，当一个（或多个）测试失败时，会显示相应的警告消息。在整个安装之前显示自定义页面。问题是，有太多的消息（在最坏的情况下）和安装程序页面很小 - 不可能显示所有这些消息而没有重叠...所以我想只显示一些标题（简要描述问题）以及在专用区域下面某处的更详细信息，但仅当鼠标移动到简短文本上时。或者，其他解决方案是创建一些可滚动区域......

但我不知道如何在NSIS中这样做。我知道.onMouseOverSection回调，但AFAIK只能在部分选择页面中使用。

是否可以在NSIS页面中进行此操作？

提前致谢。

我不认为在instfiles页面上这样做是个好主意。我会去一个自定义页面。如果您决定使用自定义页面构思，则可能有3个选项：

创建一个自定义nsis插件，以任何您想要的方式显示页面。
使用nsDialogs创建自定义页面，并使用WndSubclass plugin处理鼠标消息。
使用两个组件页面并调整其中一个。

以下示例使用第3个选项，因为它仅使用官方nsis插件。
