WXTREECTRL自定义事件

wxTreeCtrl custom event

本文关键字：事件 自定义 WXTREECTRL      更新时间：2023-10-16

我正在为wxtreectrl的事件而苦苦挣扎，无法让他们开火。我希望一个更改选择事件要开火，并尝试查看TreectRL代码样本。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
};

如果您能看到任何东西，我将非常感谢建议。我刚刚通过尝试在OnSelchanged函数中放置一个断点，但它没有达到它。

您正在使用错误的控制ID。在创建ID TopRightPanel_Ctrl的事件接收器时，您可以使用0的ID创建TreectRl：

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