指向DRAWITEMSTRUCT结构的长指针,其中包含有关所需绘图类型的信息。 备注 DRAWITEMSTRUCT结构的itemAction和itemState成员定义要执行的绘图操作。 默认情况下,此函数绘制一个默认复选框列表,其中包含一个字符串列表,每个字符串左侧都有一个采用默认大小的复选框。 复选框列表大小是Create中指定的大小。

对Typescript中可为空的类型进行Nullcheck 在Typescript中,可为空的类型可以通过Nullcheck来处理。Nullcheck是一种检查变量是否为空的机制,可以帮助开发人员在运行时避免出现空引用错误。 在Typescript中,可以使用三种方式进行Nullcheck: 使用if语句进行Nullcheck: 代码语言:txt 复制 let myVariable: string | null =...
