9 11.3.3.4 使能(Enable)与可见性(Visible)属性 【*例11.3.3.4-1】 本例目标:制作一个带四个子菜单项的顶层菜单项;

该下拉菜单分为两 个功能区;

每个功能区的两个菜单项是相互对立的,因此采用使能属性处理;

当图形窗坐 标轴消隐时,整个坐标分隔控制功能区不可见. (1)编写如下脚本 M 文件 exm11334_1.m [exm11334_1.m] clf h_menu=uimenu('

label'

,'

Option'

);

%产生顶层菜单项Option h_sub1=uimenu(h_menu,'

label'

,'

Axis on'

);

%产生Axis on菜单项,由缺省设置而使能 h_sub2=uimenu(h_menu,'

label'

,'

Axis off'

,... '

enable'

,'

off'

);

%产生Axis off菜单项,但失能 h_sub3=uimenu(h_menu,'

label'

,'

Grid on'

,... '

separator'

,'

on'

,'

visible'

,'

);

%产生与上分隔的Grid on菜单项,但不可见 h_sub4=uimenu(h_menu,'

label'

,'

Grid off'

,... '

);

%产生Grid off菜单项,但不可见 set(h_sub1,'
