如何在wxListCtrl中设置sizer

Question

我想创建一个框架，它包含一个面板，在它下面有一个wxListCtrl，当我最小化或最大化框架时，Listctrl不依赖于Frame.so。谁能告诉我怎样才能使我的wxListCtrl框架依赖。我知道sizer会在这里工作，我用过了，我想我用错了。我的代码是：

Id_Search_Report::Id_Search_Report(const wxString &title)
      :wxFrame (NULL,1,title,wxDefaultPosition,wxSize(985,650),wxDEFAULT_FRAME_STYLE)
    {
/*
\---------------------------------------------------------------------------------
              INITIALIZAION OF COUNTER WITH 0
---------------------------------------------------------------------------------
*/
        this->counter=0;
/*
---------------------------------------------------------------------------------
              CALLING PANEL CONSTRUCTOR
---------------------------------------------------------------------------------
*/
        panel_first =new wxPanel(this, wxID_ANY, wxDefaultPosition,  wxDefaultSize, wxTAB_TRAVERSAL,wxT(""));
        wxBoxSizer *vbox = new wxBoxSizer(wxVERTICAL);
                panel_first->SetSizer(vbox);

/*
---------------------------------------------------------------------------------
              CALLING LIST CONTROL CONSTRUCTOR
---------------------------------------------------------------------------------
*/
        data_list_control= new wxListCtrl(panel_first, wxID_ANY, wxPoint(0,0), wxDefaultSize, wxLC_REPORT,wxDefaultValidator);
        vbox->Add(data_list_control,1,wxEXPAND);

/*
---------------------------------------------------------------------------------
               CALLING CLOSE BUTTON CONSTRUCTOR
---------------------------------------------------------------------------------
*/
        submit=new wxButton(panel_first,41,BUTTON_CLOSE ,wxPoint(880,620), wxDefaultSize);
        back =new wxButton(panel_first, 42,BUTTON_BACK ,wxPoint(880,630), wxDefaultSize);
/*
---------------------------------------------------------------------------------
               CREATING EVENT FOR CLOSE BUTTON CLICKED
---------------------------------------------------------------------------------
*/
        Connect(41, wxEVT_COMMAND_BUTTON_CLICKED,wxCommandEventHandler(Id_Search_Report::onbuttonclick));
/*
---------------------------------------------------------------------------------
               INITIALIZATION OF LIST CONTROL COLOUMN
               INSERT COLOUMN PARAMETERS ARE:-(ID, HEADER TEXT, ALLIGNMENT(2 FOR MIDDLE)
---------------------------------------------------------------------------------
*/
        data_list_control->InsertColumn(0,COLOUMN_1,2);
        //data_list_control->SetColumnWidth(0, 80);
        data_list_control->InsertColumn(1,COLOUMN_2,2);
        //data_list_control->SetColumnWidth(1, 80);
        data_list_control->InsertColumn(2,COLOUMN_3,2);
        //data_list_control->SetColumnWidth(2, 80);
        data_list_control->InsertColumn(3,COLOUMN_4,2);
        //data_list_control->SetColumnWidth(3, 80);
        data_list_control->InsertColumn(4,COLOUMN_5,2);
        //data_list_control->SetColumnWidth(4, 80);
        data_list_control->InsertColumn(5,COLOUMN_6,2);
        //data_list_control->SetColumnWidth(5, 80);
        data_list_control->InsertColumn(6,COLOUMN_7,2);
        //data_list_control->SetColumnWidth(6, 80);
        data_list_control->InsertColumn(7,COLOUMN_8,2);
        //data_list_control->SetColumnWidth(7, 80);
        data_list_control->InsertColumn(8,COLOUMN_9,2);
        //data_list_control->SetColumnWidth(8, 80);
        data_list_control->InsertColumn(9,COLOUMN_10,2);
        //data_list_control->SetColumnWidth(9, 80);
        data_list_control->InsertColumn(10,COLOUMN_11,2);
        //data_list_control->SetColumnWidth(10, 80);
        data_list_control->InsertColumn(11,COLOUMN_12,2);
        //data_list_control->SetColumnWidth(11, 80);
        //sizer


    }

Answer 1

在我看来，您实际上并没有创建一个框架。尽管继承了wxFrame()类，但尚未创建框架。我会打电话给

 wxFrame::Create( parent, id, caption, pos, size, style )

在任何事情之前，请先给你帧。然后，您可能希望使用以下内容来引用此框架

Id_Search_Report *myFrame = this;

为了清晰起见，不要使用this指针，并将面板放在此框架的顶部。

希望这能有所帮助

Answer 2

据我所知，您希望更改控件的大小，因为顶部框架的大小是由用户更改的。

为此，您需要响应当fram更改大小时生成的sizer事件。如下所示：

EVT_SIZE(Id_Search_Report::OnSize)

void MyFrame::OnSize(wxSizeEvent& )
{
  if( data_list_control) {
    data_list_control->SetSize(GetClientRect());
  }
}
