解决QT:forward declaration of 'struct Ui::xxx';invalid use of incomplete struct "Ui::Widget" 等莫名奇妙错误 今天在进行QT Widget的UI设计时,改了下Widget的对象名,然后在多次成功编译运行后,执行清理,重新构建,就出现了好多莫名奇妙的错误: widget.h:12: 错误:forward declaration of 'struct Ui::Widget'...
每当你新键一个 QT设计界面, QT会自动生成yyy.ui文件,如 <?xml version="1.0" encoding="UTF-8"?><uiversion="4.0"><class>Form</class><widgetclass="QWidget"name="Form"><propertyname="geometry"><rect><x>0</x><y>0</y><width>400</width><height>300</height></rect></property><proper...
you can't define myotherstruct again, because you previously typedefed it as mystruct! try tp #define it instread of typedefing it, and themm #undef it before the forward declaration! Jul 19, 2012 at 9:58pm vlad from moscow(6539) ...
You do not have complete type struct ElementoDiLista. You have complete type struct elemento and its alias ElementoDiLista. struct elemento { int info; struct elemento* next; }; typedef struct elemento ElementoDiLista; So instead of this typedef definition typedef struct Eleme...

int main() { // forward declaration struct myStruct_st *mS; // Note that this will expand as "struct struct myStruct_st *mS which does not make any sense to me" return 0; } // definition of myStruct_s typedef struct myStruct_s { int x; int y; } myStruct_st; 我知道myStruct...
struct Bar; void Foo(Bar* b); ...and then foo.cpp would presumably include bar.h, if in fact it needed to know what Bar consisted of. How can I accomplish a similar thing in (legal) C? I've tried the C++ forward-declaration strategy, e.g. struct Bar; void Foo(struct Bar* b...
// Forward declaration enum myEnumProcessState; 我随后在一个结构体中使用了这个枚举: struct myStruct { [...] myEnumProcessState osState; [...] }; 并在另一个标题中: enum myEnumProcessState { eNotRunning, eRunning }; 我发现应该在枚举类型的前向声明中加入类型才能被接受。然而,我不知道对...
