在GUI的静态文本中创建多行“字符串"

问题描述

我在GUI中有一个静态文本，需要编写如下内容:

I have a static text in GUI and need to write something like:

y1 = A[1]
y2 = A[2]
y3 = A[3]

等(有一定的限制，现在这并不重要).

etc. (there is a certain limit, right now this is not important).

其中y1, y2, y3是字符串，而A[1], A[2], A[3]是数字在矩阵A中.

Where y1, y2, y3 are strings, and A[1], A[2], A[3] are numbers in a matrix A.

我只是不确定如何在该静态文本中输入新行，这意味着我不确定如何从y1转到y2.

I'm just not sure how to enter a new line in that static text, meaning I'm not sure how to go from y1 to y2.

我知道互联网上对此问题有很多答案，但是由于某种原因我找不到适合我需求的答案.

I know there are a lot of answers to this question on the Internet but I can't find one that suits my needs for some reason.

我该怎么做?

谢谢.

推荐答案

请确保static-text的伸展距离足以容纳这些多行文本.这是一个演示，其中包含A中的一些样本值.诀窍是在每个单元格代表每个这样的赋值文本时使用Nx1 cell array.代码必须清楚-

Make sure that the static-text is stretched far enough to accommodate those multi-lines text. Here's a demo with some sample values in A. The trick is to use a Nx1 cell array with each cell representing each such assignment text. The code must make it clear -

A = [4 9 22 29 34 47 56 78 100]; %// Assumed as a vector for demo

cellstrg = cell(numel(A),1);
for k = 1:numel(A)
    cellstrg(k) = {['y',num2str(k),' = ' ,num2str(A(k))]};
end
set(handles.text1,'String',cellstrg) %// handles.text1 is tag to that static text

您可以使用cellfun方法避免for循环，这种方法可能效率不高，但只是实现同一件事的一种简洁方法-

You can avoid the for-loops with a cellfun approach, which might not be efficient, but just a concise way of achieving the same thing -

cellstrg = strcat('y',cellstr(num2str([1:numel(A)]')),'=',strtrim(cellstr(num2str(A'))))

在GUI上输出-
