Scilab -在GUI中调用另一个GUI.函数不工作

Question

我对scilab非常陌生，我创建了两个gui(见下面的示例)，其中脚本2从脚本1调用。然而，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

Answer 1

问题

这是一个范围问题。当函数exam_callback()被调用时，它与exec('costs0-1.sce',-1)一起运行另一个脚本。在该脚本中，您定义了函数Calculate_callback(handles)。当exam_callback()完成时，它将超出范围并被删除，因此当按下按钮时不能调用。

第二个问题是句柄不受全局影响，所以当离开exam_callback()时，第二个成本Gui的句柄不会添加到handles。

解决方案

您可以将GUI的生成移到函数createCostGui()中，然后在script1的开头使用exec('costs0-1.sce',-1);加载script2。

使Calculate_callback(handles)函数放弃handles参数并使用标记来查找handles

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

Text元素通常是静态的，因此不需要Callback参数。如果您希望参数保持其默认值，则不需要指定它们。

来自Scilab文档:

h = uicontrol(PropertyName, PropertyValue，…)创建一个uicontrol并为其分配指定的属性和值。它将默认值分配给您未指定的任何属性。默认的uicontrol样式是"Pushbutton"。默认父图形是当前图形。有关这些属性和其他属性的信息，请参阅属性部分。
