[英]How to show some text on mouse move in NSIS installer
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,但只能在鼠标悬停时显示?
我在安装程序的开头进行了先决条件检查,当一个(或多个)测试失败时,将显示相应的警告消息。 这是在整个安装之前显示的自定义页面。 问题是,有太多消息(在最坏的情况下)并且安装程序页面很小-无法覆盖所有消息而不显示它们...所以我只想显示一些标题(简要描述问题)和更详细的信息(位于专用区域下面的某个位置),但仅限于将鼠标移到简短文本上时。 或者,其他解决方案是创建一些可滚动区域。
但是我不知道如何在NSIS中做到这一点。 我知道.onMouseOverSection回调,但是AFAIK它只能在节选择页面中使用。
是否可以在NSIS页面中执行此操作?
提前致谢。
我认为在instfiles
页面上执行此操作不是一个好主意。 我会去自定义页面。 如果您决定采用自定义页面提示,则可能有3个选择:
以下示例使用第三个选项,因为它仅使用官方的nsis插件。
