Waitbar在水平步骤,matlab

Question

我正在尝试修改此代码

h = waitbar(0,'Please wait...');

for i=1:10, % computation here %  waitbar(i/10) end
close(h)

如何将waitbar分成10个步骤.我的意思是它应该看起来像

Answer 1

以下代码允许您向等待栏添加垂直线:

hWait = waitbar(0,'Progress');  %# Create the waitbar and return its handle
hAxes = get(hWait,'Children');  %# Get the axes object of the waitbar figure
xLimit = get(hAxes,'XLim');     %# Get the x-axis limits
yLimit = get(hAxes,'YLim');     %# Get the y-axis limits
xData = repmat(linspace(xLimit(1),xLimit(2),11),2,1);  %# X data for lines
yData = repmat(yLimit(:),1,11);                        %# Y data for lines
hLine = line(xData,yData,'Parent',hAxes,...  %# Plot the lines on the axes...
             'Color','k',...                 %#   ... in black...
             'HandleVisibility','off');      %#   ... and hide the handles

在运行上面的代码然后执行之后waitbar(0.35,hWait);,您将看到如下图:

注意:绘图中的黑线(我添加的垂直线和进度条周围已存在的框)将在更新时间歇性地出现在红色进度条的上方或下方.这似乎是WAITBAR行为的现有错误,我还没有找到解决方法来纠正它.但是,在MathWorks文件交换中可以找到很多替代方案,所以如果内置函数不能用于ya,我肯定会检查出来.;)
