我维护的软件包的一个功能是将用户的产品速记名称解析为其全名。在踢回用户输入之前,软件会尝试两种方法自动执行此操作。如果自动尝试失败,则请求用户与表匹配。
GUI部分非常大,因此它保留在自己的子功能中。子函数只返回idx
或索引变量。我很难让matlab“耐心”等待GUI指定idx。
以下是带注释的代码的重要部分:
function [ idx ] = mnmhelper( modeldb )
%mnmhelper makes a UI table for the user to manually select the correct
%model
%% uitable generation
f = figure('UserData',1); %userdata will be the selection;
t = uitable('Parent',f,...
'Data',modeldb.Model,...
'CellSelectionCallback',@select_callback);
b = uicontrol('Parent', f,...
'Style','pushbutton',...
'String','Commit Model Name',...
'Callback',@button_callback);
%% callbacks - note that these are nested in the parent fnc
function select_callback(hObject , eventdata)
%hObject - handle to uitable
%eventdata - currently selected table indexes
f.UserData = eventdata.Indices; % pass selection as userdata array: [row,col]
end
function button_callback(hObject,eventdata,selection)
idx = f.UserData(1);
close(f);
figclosed = 1; %see additional notes below code on this line
end
end
问题是matlab会错误地定义idx,因为它没有等待使用该数字。
我试图添加以下部分:
%% strongarm matlab into waiting for user to do this
figclosed = 0;
while figclosed < 1 %don't evaluate to command line until figure is finished
% ... do nothing
% once this evaluates to ==1 and kicks out of this, idx is defined
end
在所有回调之后,但是matlab将在while循环中等待并且数字不会生成。我如何让matlab等待?
我是否需要CreateFcn
才能使matlab等待?
