c++ - wxTreeCtrl 自定义事件

Question

我正在努力处理 wxTreeCtrl 的事件，无法触发它们。我想要触发更改选择事件并尝试查看 treeCtrl 代码示例。到目前为止，我有:

.cpp

TopRightPanel::TopRightPanel(wxWindow *parent, wxSizer* sizer)
: wxTreeCtrl(parent, 0, wxPoint(513, 0), wxSize(512, 384)) //wxPanel(parent, 513, 0, 512, 384)
{
CreateControls(this);;
}



void TopRightPanel::CreateControls(wxTreeCtrl* parent)
{
    rootId = wxTreeItemId();
    rootId = AddRoot("Particle Systems");
    wxTreeItemId root2Id = parent->AppendItem(rootId, "dlisjdslj");



parent->AppendItem(rootId, "Child 1");
}

void TopRightPanel::OnSelChanged(wxTreeEvent& event)
{

}

    #if USE_GENERIC_TREECTRL
    BEGIN_EVENT_TABLE(TopRightPanel, wxGenericTreeCtrl)
    #else
    BEGIN_EVENT_TABLE(TopRightPanel, wxTreeCtrl)
   #endif

EVT_TREE_SEL_CHANGED(TopRightPanel_Ctrl, TopRightPanel::OnSelChanged)

END_EVENT_TABLE()

#define TREE_EVENT_HANDLER(name)                                 \
void TopRightPanel::name(wxTreeEvent& event)                        \
{                                                                \
    LogEvent(wxT(#name), event);                                  \
    SetLastItem(wxTreeItemId());                                 \
    event.Skip();                                                \
}

/*TREE_EVENT_HANDLER(OnBeginRDrag)
TREE_EVENT_HANDLER(OnDeleteItem)
TREE_EVENT_HANDLER(OnGetInfo)
TREE_EVENT_HANDLER(OnSetInfo)
TREE_EVENT_HANDLER(OnItemExpanded)
TREE_EVENT_HANDLER(OnItemExpanding)
TREE_EVENT_HANDLER(OnItemCollapsed)*/
//TREE_EVENT_HANDLER(OnSelChanged)
//TREE_EVENT_HANDLER(OnSelChanging)

#undef TREE_EVENT_HANDLER

.h

class TopRightPanel : public wxTreeCtrl
{
public:
    TopRightPanel(wxWindow *parent, wxSizer *sizer);
    void CreateControls(wxTreeCtrl *parent);
    void CreateNewParent(wxTreeCtrl *parent);
    void CreateNewChild(wxTreeCtrl *parent, wxTreeItemId *root);
    void OnSelChanged(wxTreeEvent& event);
    void LogEvent(const wxChar *name, const wxTreeEvent& event);
    //void OnSelChanging(wxTreeEvent& event);

private:
    wxTreeItemId rootId;
    //DECLARE_DYNAMIC_CLASS(TopRightPanel);
    DECLARE_EVENT_TABLE()
    /*void OnSetText(wxCommandEvent & event);
    wxStaticText *m_text;*/

};
enum
{
    TopRightPanel_Select = 6000,
    TopRightPanel_Unselect,
    TopRightPanel_Ctrl = 1000
};

如果您能看到任何建议，我将不胜感激。到目前为止，我只是通过尝试在 OnSelChanged 函数中放置一个断点来进行测试，但它没有命中它。

您使用了错误的控件 ID。您创建 ID 为 0 的 TreeCtrl，同时为 ID TopRightPanel_Ctrl 创建事件接收器:

: wxTreeCtrl(parent, TopRightPanel_Ctrl, ...
//                    ^
//                    | they need to match
//                    v
EVT_TREE_SEL_CHANGED(TopRightPanel_Ctrl, ...
