如何在指南Matlab中创建下一个按钮和反向按钮
如何在指南Matlab中创建下一个按钮和反向按钮
提问于 2014-06-23 16:11:23
我正在制作一个GUI，我正在使用它的指南。在写我的问题之前，我必须解释一些细节，它们是:数据的-Kind :文本文件，来自人体两条腿的16块肌肉肌电的数据，所以我必须绘制16张图表。我的图形用户界面的-Objective是显示4在每个“页面”，所以我需要下一个按钮和后退按钮，能够看到所有的16个graphs.In其他词，我的GUI需要4个“页面”。-My指南由1次底部浏览我的数据，1次底部切换(更新)4个图形的形状显示在ABS中，图与信封，和一个组合的ABS和包络图，一个菜单来切换显示的图形的形状，和两个额外的底部，一个是下一个按钮，另一个是后退按钮。
总之，我只是停留在如何创建下一个按钮和后退按钮。我的代码的其他角色已经开发出来了。
提前谢谢。
Ps:谢谢你建议我改进我的问题。
是的，我想重绘我的图表(我的英语不太好，所以我无法解释得更好)

让我纠正你的代码，告诉你你犯的小错误(我不是很有经验，但我认为这能帮你)。我没有试图理解textscan(...)调用，因为我没有您的一个txt文件。
function Search_Patient_Callback(hObject, eventdata, handles)
% global cell_data (I avoid global variables)
[file, path]=uigetfile('*.txt', 'Select file');
% arq = [path,file]; (it is the same as below, no ?)
full_pathname=strcat(path,file);
text=fileread(full_pathname);
cell_data= textscan(text, repmat('%f',1,41),'headerlines',11);
delimiter = '\t';
startRow = 3;
endRow = 8;
formatSpec = '%*s%*s%*s%f%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%*s%[^\n\r]';
fileID = fopen(full_pathname,'r');
textscan(fileID, '%[^\n\r]', startRow-1, 'ReturnOnError', false);
dataArray = textscan(fileID, formatSpec, endRow-startRow+1, 'Delimiter', delimiter, 'ReturnOnError', false);
time_foot1 = dataArray{:, 1};
% Now store the relevant data in the handles structure :
handles.timefoot=timefoot1;
handles.cell_data=cell_data;
guidata(hObject,handles); % This line saves the current handles (so it saves the changes above)
% handles = guidata(hObject); % This line replaces current handles with the one stored. Use it only in the beginning of a function that doesn't take handles as an input, or after a call to a function that affects handles.然后
function Updating_Callback(hObject, eventdata, handles)
y_data=0.001;
t=(handles.cell_data{1,1})/1000; % else you can say 'cell_data=handles.cell_data;' and use 'cell_data' as you did
%time_foot1= getappdata(0,'time_foot'); (let is use the handles structure instead of getappdata)
time_foot1=handles.time_foot;
text_rfoot=0.0009;
text_lfoot=0.0007;
[emg1_1 emg2_1 emg3_1 emg4_1 emg1e_1 emg2e_1 emg3e_1 emg4e_1]=emg_signal(handles.cell_data); % EMG RMS and EMG Envelope
popup_sel_index = get(handles.popupmenu, 'Value');
switch popup_sel_index
[skipping a few lines]
end
% a=get(handles.next_pushbutton,'Value') (what for ??)
% handles = guidata(hObject) (you do not want to erase the handles structure do you ?)
guidata(hObject,handles); % OK but not neccesary because nothing changed in the handles structure in the function)现在，，您想要做的事情，是修改您的更新函数，以便它考虑到您推送上一个/返回的次数。我认为。因此，我将在GUI handles.index=1中创建一个简单的变量OpeningFcn (别忘了用guidata保存它)，每次按下其中一个按钮，就会修改它的值(+1或-1)。然后在更新函数中，newIndex=mod(handles.index,4);和newIndex告诉您必须显示哪个“平面”。
另一种解决方案是使用另一个带有字符串{'1','2','3','4'}的弹出菜单，并在您已经使用它时使用它。
