这是一个关于网络设备命令行接口(CLI)中角色权限的描述。`role name level-0`是创建一个名为"level-0"的角色,这个角色的权限级别是0,即最低权限级别。这个角色的描述是“Predefined level-0 role”,意为预定义的级别0角色。在网络设备中,通常会预定义一些角色,如级别0、级别1、级别15等,每个角色都有不同的权限和能力,用于控制用户对设备的访问和操作。级别0是最低权限级别,通常只能查看和执行一些基本操作,而级别15是最高权限级别,可以访问和控制设备的所有功能和配置。其他级别的权限则介于两者之间。通过定义不同级别的角色和分配给不同的用户,可以实现对网络设备的分层访问和管理。

Qt::UserRole
Qt::UserRole is a constant integer value defined in the Qt framework. It is used as a base role for user-defined data roles in item models.
In Qt's item models, data is stored in a table-like data structure, with rows and columns. Each cell in the table can hold data, and each cell is identified by a QModelIndex, which specifies its row and column. In addition to the row and column, a QModelIndex can also specify a data role, which identifies the type of data stored in the cell.
Some common data roles used in Qt's models include Qt::DisplayRole (for the data displayed to the user), Qt::EditRole (for the data displayed when the cell is being edited), and Qt::ToolTipRole (for the tooltip text displayed when the mouse hovers over the cell).
Qt::UserRole is a constant that can be used as a base role for user-defined data roles. For example, if you want to associate additional data with a cell in an item model, you can use a data role that is greater than or equal to Qt::UserRole. This ensures that the role you use does not conflict with any of the predefined roles used by Qt's models.
