如何在wxwidgets中将AppendCheckItem默认设置为"check“？

wxCheckListBox* checklistbox = new wxCheckListBox(parent, wxID_ANY, wxDefaultPosition, wxDefaultSize);

checklistbox->Append("Option 1");
checklistbox->Append("Option 2");

checklistbox->Check(0); // 将第一个选项设置为选中状态

sizer->Add(checklistbox, 1, wxEXPAND | wxALL, 5);

#include <wx/wx.h>
#include <wx/checklst.h>

class MyFrame : public wxFrame
{
public:
    MyFrame() : wxFrame(NULL, wxID_ANY, "wxWidgets CheckListBox Example")
    {
        wxPanel* panel = new wxPanel(this, wxID_ANY);

        wxBoxSizer* sizer = new wxBoxSizer(wxVERTICAL);

        wxCheckListBox* checklistbox = new wxCheckListBox(panel, wxID_ANY, wxDefaultPosition, wxDefaultSize);
        checklistbox->Append("Option 1");
        checklistbox->Append("Option 2");

        checklistbox->Check(0); // 将第一个选项设置为选中状态

        sizer->Add(checklistbox, 1, wxEXPAND | wxALL, 5);

        panel->SetSizerAndFit(sizer);
    }
};

class MyApp : public wxApp
{
public:
    virtual bool OnInit()
    {
        MyFrame* frame = new MyFrame();
        frame->Show();
        return true;
    }
};

wxIMPLEMENT_APP(MyApp);
