将command中的信息显示在edit中
本帖最后由 shizhi214 于 2010-8-31 15:47 编辑请问：在matlab GUI中，如何将command窗口中的运行警告信息发送到GUI的edit窗口中？
另外就是希望edit框中的内容是可以追加的，也就是说，程序有多个地方向edit框输出信息，后一条输出的信息自动添加到前一条的后面，而不是象set（）那样，之前的信息就没有了。
请问如何实现 1.这个问题是要获得command window窗口的字符串，希望下面几句话对你有所帮助mde = com.mathworks.mde.desk.MLDesktop.getInstance;
cw = mde.getClient('Command Window');
xCmdWndView = cw.getComponent(0).getViewport.getComponent(0);xCmdWndView 是结构体，他的text属性就是command窗口的字符串
2.自动添加，你可以把之前的字符串保存下面，新的接在后面，然后更新字符串
建议你可以参考一下

找不到你说的xCmdWndView 的Text 属性。
>> mde = com.mathworks.mde.desk.MLDesktop.getInstance;
cw = mde.getClient('Command Window');
xCmdWndView = cw.getComponent(0).getViewport.getComponent(0);
>> fieldnames(xCmdWndView)
ans =
'FOCUS_ACCELERATOR_KEY'
'DEFAULT_KEYMAP'
'WHEN_FOCUSED'
'WHEN_ANCESTOR_OF_FOCUSED_COMPONENT'
'WHEN_IN_FOCUSED_WINDOW'
'UNDEFINED_CONDITION'
'TOOL_TIP_TEXT_KEY'
'TOP_ALIGNMENT'
'CENTER_ALIGNMENT'
'BOTTOM_ALIGNMENT'
'LEFT_ALIGNMENT'
'RIGHT_ALIGNMENT'
'WIDTH'
'HEIGHT'
'PROPERTIES'
'SOMEBITS'
'FRAMEBITS'
'ALLBITS'
'ERROR'
'ABORT'
>> fieldnames(cw)
ans =
'WHEN_FOCUSED'
'WHEN_ANCESTOR_OF_FOCUSED_COMPONENT'
'WHEN_IN_FOCUSED_WINDOW'
'UNDEFINED_CONDITION'
'TOOL_TIP_TEXT_KEY'
'TOP_ALIGNMENT'
'CENTER_ALIGNMENT'
'BOTTOM_ALIGNMENT'
'LEFT_ALIGNMENT'
'RIGHT_ALIGNMENT'
'WIDTH'
'HEIGHT'
'PROPERTIES'
'SOMEBITS'
'FRAMEBITS'
'ALLBITS'
'ERROR'
'ABORT' 说错了，不是结构体，我不知道是什么类型，应该是java class或者user class或者dataset之类吧
但是可以得到从text中找到输入的字符串>> magic(3)
ans =
8 1 6
3 5 7
4 9 2
>> mde = com.mathworks.mde.desk.MLDesktop.getInstance;
cw = mde.getClient('Command Window');
xCmdWndView = cw.getComponent(0).getViewport.getComponent(0);
>> get(xCmdWndView,'text')
ans =
>> magic(3)
ans =
8 1 6
3 5 7
4 9 2
>> mde = com.mathworks.mde.desk.MLDesktop.getInstance;
cw = mde.getClient('Command Window');
xCmdWndView = cw.getComponent(0).getViewport.getComponent(0);
>> get(xCmdWndView,'text') 5# qibbxxt
谢谢，现在我想把程序运行的时间记录到指定的文件中，但是有时可以实现，有时又不能实现，看看是什么问题。
下面是M文件中的程序：
clc;
tic
% 记录程序运行时间到指定的文件中。
% 程序段
for k = 1:10^6
k;
end
% 程序段
toc
mde = com.mathworks.mde.desk.MLDesktop.getInstance;
cw = mde.getClient('Command Window');
xCmdWndView = cw.getComponent(0).getViewport.getComponent(0);
mystr = get(xCmdWndView,'text');
fid = fopen('myfile.m','w');
fprintf(fid,'%s\n',mystr);
fclose(fid);
type myfile.m
6# lin2009
你的这个程序在我的电脑上面运行正常
7# qibbxxt
多运行几次，不是每一次都正常，我的版本是2010a。 clc;clear
% 记录程序运行时间到指定的文件中。
% 程序段
if exist('myfile.m')
delete myfile.m
end
tic
for k = 1:10^6
k;
end
% 程序段
toc
mde = com.mathworks.mde.desk.MLDesktop.getInstance;
cw = mde.getClient('Command Window');
xCmdWndView = cw.getComponent(0).getViewport.getComponent(0);
mystr = get(xCmdWndView,'text');
fid = fopen('myfile.m','w');
fprintf(fid,'%s',mystr);
fclose(fid);
for i=1:20
clc
tic
% 记录程序运行时间到指定的文件中。
% 程序段
for k = 1:10^6
k;
end
% 程序段
toc
mde = com.mathworks.mde.desk.MLDesktop.getInstance;
cw = mde.getClient('Command Window');
xCmdWndView = cw.getComponent(0).getViewport.getComponent(0);
mystr = get(xCmdWndView,'text');
fid = fopen('myfile.m','at');
fprintf(fid,'%s',mystr);
fclose(fid);
end
dbtype myfile.m这是我运行了21次，得出的结果Elapsed time is 0.023347 seconds.
