Function Scilab-在GUI中调用另一个GUI。功能不工作

我对scilab非常陌生，我创建了两个GUI（参见下面的示例），其中脚本2是从脚本1调用的。但是，脚本2中的函数似乎不起作用。有人能帮忙吗

脚本1

'//////////
f=figure('figure_position',[0,0],'figure_size',[1250,650]);
//////////
delmenu(f.figure_id,gettext('File'))
delmenu(f.figure_id,gettext('?'))
delmenu(f.figure_id,gettext('Tools'))
toolbar(f.figure_id,'off')

handles.dummy = 0 ;

handles.exam=uicontrol(f,'unit','normalized','BackgroundColor',        [0.5,1,1],'Enable','on','FontAngle','normal','FontName','helvetica','FontSize',[14],'FontUnits','points','FontWeight','bold','ForegroundColor',[0,0.5,0],'HorizontalAlignment','center','ListboxTop',[],'Max',[1],'Min',[0],'Position',[0.5,0.5,0.1,0.05],'Relief','flat','SliderStep',[0.01,0.1],'String','exam','Style','pushbutton','Value',[0],'VerticalAlignment','middle','Visible','on','Tag','obj102','Callback','exam_callback(handles)')

function exam_callback(handles)
close(f);
clear
exec('costs0-1.sce',-1) ; 
endfunction`

脚本2

f=figure('figure_position',[0,0],'figure_size',[1250,650],'auto_resize','on','background',[8]);

function Calculate_callback(handles)
if handles.service.value == 1 then
resource_hrs = 2
end

if handles.service.value == 2 then
resource_hrs = 10
end

set(handles.totalhours,'String',string(resource_hrs));

endfunction

问题 这是一个范围界定问题。调用函数

exam\u callback（）

时，它将使用

exec（'costs0-1.sce'，-1）

运行另一个脚本。 在该脚本中定义函数

Calculate\u callback（handles）

。这超出了范围，在

exam\u callback（）

完成时被删除，因此在按下按钮时无法调用

第二个问题是句柄不会受到全局影响，因此当离开

exam\u callback（）

时，第二个Cost Gui的句柄不会添加到

句柄中

解决方案
您可以将GUI的生成移动到函数
createCostGui（）
中，然后在script1的开头用
exec（'costs0-1.sce'，-1）加载script2

要使
Calculate\u回调（句柄）
函数放弃handles参数，并使用标记查找句柄

function Calculate_callback()

    serviceHandle = findobj('tag','service');

    if serviceHandle.value == 1 then
        resource_hrs = 2
    end

    if serviceHandle.value == 2 then
        resource_hrs = 10
    end

    totalHoursHandle = findobj('tag','totalhours');

    set(totalHoursHandle,'String',string(resource_hrs));

endfunction

进一步评论
文本元素通常是静态的，因此不需要回调参数。
如果希望参数保持默认值，则无需指定它们

从：

h=uicontrol（PropertyName，PropertyValue，…）创建一个uicontrol并为其指定属性和值。它将默认值指定给未指定的任何特性。默认的uicontrol样式是“按钮”。默认父对象是当前图形。有关这些属性和其他属性的信息，请参阅“属性”部分

对你的问题说几句话

下次出现错误消息时，您的问题可能会更具体。
非常感谢您花费的时间和精力，效果非常好！
