我不确定我是否以正确的方式进行此操作,但我希望有一个功能,当被调用时,基本上重置4个图。我将图存储为handles.distplot1
,handles.distplot2
等等,希望有一个下拉菜单来选择轴上显示的图。我需要在几个不同的事件之后重置这些图,所以我很自然地想把它们放在一个函数中并避免代码冗余。我希望像
function setupDistPlots(hObject, eventdata, handles)
% filler data for surfc
x = [1 2];
z = zeros(2);
% setup blank plots for funtion to work with
a = figure(1); set(a, 'Visible', 'off')
handles.distplot1 = surfc(x, x, z);
b = figure(2); set(b, 'Visible', 'off');
handles.distplot2 = bar(NaN);
c = figure(3); set(c, 'Visible', 'off')
handles.distplot3 = surfc(x, x, z);
d = figure(4); set(d, 'Visible', 'off')
handles.distplot4 = bar(NaN);
guidata(hObject, handles);
我认为应该按预期工作,但我不知道如何调用它。在open函数中,我尝试setupDistPlots(hObject, eventdata, handles)
,但在稍后尝试访问handles.distplot1
时收到以下错误:
Reference to non-existent field 'distplot1'.
Error in tabbedGUI>distanceToggle_Callback (line 212)
distribution(hObject,
handles.distplot1, ...
Error in gui_mainfcn (line 95)
feval(varargin{:});
Error in tabbedGUI (line 45)
gui_mainfcn(gui_State, varargin{:});
Error in
@(hObject,eventdata)tabbedGUI('distanceToggle_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating UIControl Callback
编辑:还请指出我可以改进的一切。我在Matlab中所做的一切都让人感觉像是一种更好的方式。
edit2:open函数的问题是在打开函数setupDistPlots
之前调用guidata(hObject, handles)
。但是现在当我按下按钮时再次调用`setupDistPlots'时,我收到以下错误:
Error using matlab.graphics.primitive.Data/set
Invalid or deleted object.
Error in andrewDistribution (line 45)
set(hplot1, 'xData', x1, 'yData', y1, 'zData', zeros(length(x1)))
Error in tabbedGUI>distanceToggle_Callback (line 200)

Error in gui_mainfcn (line 95)

答案 0 :(得分:1)
我假设你的初步尝试看起来像这样:
% --- Executes just before testgui is made visible.
function testgui_OpeningFcn(hObject, eventdata, handles, varargin)
% Choose default command line output for testgui
handles.output = hObject;
setupDistPlots(hObject, eventdata, handles)
% Update handles structure
guidata(hObject, handles);
正如评论中所述,您对handles
使用guidata
保存到GUI的setupDistPlots
结构的更改将被GUIDE随后的{{1}覆盖调用。简短的回答是在 guidata
之后放置setupDistPlots
以使所有内容都按照书面形式运行。
现在答案更长。我猜你很熟悉,主要是与MATLAB scripts rather than MATLAB functions合作。脚本共享基础工作区的位置functions each have their own separate workspace in memory。如上所述,guidata
无法知道您已更改OpeningFcn
结构,因此使用传递给handles
的{{1}}值很高兴覆盖您的更改}。要解决这个问题,您需要为handles
提供一些方法来了解您已做出更改。
setupDistPlots
的一种方法是specify an output:
OpeningFcn
在您的GUIDE代码中setupDistPlots
来电之前放置function handles = setupDistPlots(hObject, eventdata, handles)
% filler data for surfc
x = [1 2];
z = zeros(2);
% setup blank plots for funtion to work with
a = figure(1); set(a, 'Visible', 'off')
handles.distplot1 = surfc(x, x, z);
b = figure(2); set(b, 'Visible', 'off');
handles.distplot2 = bar(NaN);
c = figure(3); set(c, 'Visible', 'off')
handles.distplot3 = surfc(x, x, z);
d = figure(4); set(d, 'Visible', 'off')
handles.distplot4 = bar(NaN);
