java - GWT: How can I reinitialize a widget in UI binder discarding all changes obtained during its life cycle? -

-

I have a UI-binder-powered composite that contains a lot of widgets and is used for item-specific information. Suppose, this is just a composite: 

  ...  & Lt; G: label ui: field = "description" /> & Lt; W: CustomPanel & gt; & Lt; W: customfu you: field = "afu" & gt; ... & lt; / w: customfu & gt; & Lt; W: Custom UI UI: Field = "Bar" & gt; ... & lt; / W: custombar & gt; & Lt; / W: CustomPanel & gt; & Lt; / H: FlowPanel & gt; & Lt; g: FlowPanel UI: field = "itemPanel2" & gt; ... & lt; / g: FlopNell & gt; ...   
 At some point, I have to hide the first panel using the  hide ()  method. However, the  hide ()  method can not be sufficient if  restart  ()  itemPanel  panel, and possibly intended for free DOM resources Which can be allocated for  CustomFoo  and  CustomBar  components, please note that  itemPanel.clear ();  Destroys all nested widgets, so a consistent call such as  title.setText (...)  has no effect because DOM has been deleted in this scenario.  
 How can I redesign  itempanel , like it has been loaded with its UI binder?  
 Thanks in advance.   
 
 
 ItemPanel to create a widget then you can use:  
  MyCompositeWidget.remove (panel1); ItemsPanel panel2 = new itemPanel (); MyCompositeWidget.add (panel2);   
 If you need a specific situation, you can use insert () rather than add ().

c++ - Redefined variable in the other module -

-
Why do we redefine the variable in other modules, so it is OK to add this module together? I have written two modules main.cpp and module.cpp as the following: // - main.cpp-- // # include & lt; Stdio.h & gt; Int main () {int i = 5; Printf ("I value is% d", i); } and // - module.cpp - // int i = 7; I am now compiling and adding g ++ as the following: g ++ -c main .cpp g ++ - c module. cao g ++ - o bin main.o module.o and it's okay. But I hope the compilation will be successful, while the linker will throw an exception like redefining varaible when I'm running .bin output then the value of i is 5 . UPD: I understand that if we use I as global variable module main.cpp that linker will throw an error. The main variable in the function is a local variable of i function. It is not visible and is present outside the function is. Consider the following example #include & lt; Iostream & gt; Int i = 3; Int main (...
