我正在尝试在wxMessageBox中显示“ string01”的值(如在“ inheritedgui.cpp”中看到的,但是当我单击“ m_button2”时,什么也没有发生,我也不知道为什么:/

我需要做哪些更改,以便当我单击“ m_button2”(显示“列表”的那个)时出现wxMessageBox?
std::string string01
)声明m_button1OnButtonClick
,并试图在另一种方法(m_button2OnButtonClick
)中使用它。要像您正在尝试的那样在另一种方法中使用它,请将std::string string01
设置为class inheritedgui
的成员变量。
然后在您致电时:
wxMessageBox(wxString(string01.c_str(), wxConvUTF8), wxT("This is the title"), wxICON_INFORMATION);
此外,是否特别需要使用std::string
而不是wxString
?如果没有,请坚持[C0]。
您还需要将此wxString声明为类的成员。
并且为了解决编译错误:
wxString
此外,最好使用wxMessageBox( string01, wxT("This is the title"), wxICON_INFORMATION );
代替Bind()
:
Connect()
在析构函数中,您不必Bind( wxEVT_CLOSE_WINDOW, &inheritedGui::OnCloseDialog, this ); Bind( wxEVT_COMMAND_BUTTON_CLICKED, &inheritedGui::m_button1OnButtonClick, this );
事件-事件将自动发生。最后-您不必声明函数
UnBind()
-如果没有,它应该可以工作。实际上,wxWidgets中的事件处理程序很少应该是虚拟的。谢谢。
