我尝试以编程方式创建GUI。它应显示以下内容:
右侧的复选框是静态的!!左侧复选框的数量取决于用户输入!
我尝试做的是创建右侧动态复选框的面板和这些面板的滚动条。
不幸的是,我对程序化GUI创建完全陌生。到目前为止,GUIDE一切都运行良好。
我找到了一个很好的例子
Adding scroll bar in subplots within GUI
用轴进入它,但我不适应复选框:( 到目前为止,这是我的尝试。
%# create figure, panel, and slider
w = 600; h = 500; %# width/height of figure
handles.hFig = figure('Menubar','figure', 'Resize','off', ...
'Units','pixels', 'Position',[200 200 w h]);
handles.hPan = uipanel('Parent',handles.hFig, ...
'Units','pixels', 'Position',[0 0 w-20 h]);
handles.hSld = uicontrol('Parent',handles.hFig, ...
'Style','slider', 'Enable','off', ...
'Units','pixels', 'Position',[w-20 0 20 h], ...
'Min',0-eps, 'Max',0, 'Value',0, ...
'Callback',{@onSlide,handles.hPan});
%# add checkbox
hcb = zeros(7,1);
clr = lines(7);
for i=1:7
hcb(i) = addcheckbox(handles);
pause(1) %# slow down so that we can see the updates
end
滑块功能未更改。这对我来说是最有问题的功能:
function hcb = addcheckbox(handles)
%# look for checkboxes
cb = findobj(handles.hPan, 'type','checkbox');
if isempty(cb)
%# create first checkbox
hcb = uicontrol(handles.hFig,'Style','checkbox',...
'String','Display file extension',...
'Value',1,'Position',[30 20 130 20]);
else
%# get height of figure
p = get(handles.hFig, 'Position');
h = p(4);
%# increase panel height, and shift it to show new space
p = get(handles.hPan, 'Position');
set(handles.hPan, 'Position',[p(1) p(2)-h p(3) p(4)+h])
% %# compute position of new axis: append on top (y-shifted)
% p = get(ax, 'Position');
% if iscell(p), p = cell2mat(p); end
% p = [p(1,1) max(p(:,2))+h p(1,3) p(1,4)];
%
% %# create the new axis
% hAx = axes('Parent',handles.hPan, ...
% 'Units','pixels', 'Position',p);
%
% %# adjust slider, and call its callback function
% mx = get(handles.hSld, 'Max');
% set(handles.hSld, 'Max',mx+h, 'Min',0, 'Enable','on')
% %#set(handles.hSld, 'Value',mx+h) %# scroll to new space
% hgfeval(get(handles.hSld,'Callback'), handles.hSld, []);
end
end
当我执行它时,我收到错误:
Error using findobj
Invalid handle
Error in addcheckbox (line 3)
cb = findobj(handles.hPan, 'type','checkbox');
这个错误是有道理的,因为我没有一个名为复选框的句柄......在示例'轴'是图中包含的预定义句柄...如何在此上下文中集成复选框?
答案 0 :(得分:0)
如上面的评论所述,GUIDE中提供了uitable
个对象,并且已经包含了复选框和滚动条。虽然我绝对更喜欢程序化GUI,但我也不想重新创建已经运行的整个GUI:)
这是一个小型的程序化示例(更容易复制/粘贴)来说明:
let f (x:int) (y:int) : int = x + y
let g (x:bool) (y:bool) (z:bool) : bool = x & y & z
type T = T with
static member ($) (T, x) = fun y -> f x y
static member ($) (T, x) = fun y z -> g x y z
let inline myFunc x y = (T $ x) y
let result1 = myFunc 3 5
let result2 = myFunc true false true
这给了我们:
