是否可以在wx.StaticText上绑定点击事件？

Question

我有这个代码：

import wx

class Plugin(wx.Panel):
    def __init__(self, parent, *args, **kwargs):
        panel = wx.Panel.__init__(self, parent, *args, **kwargs)
        self.colorOver = ((89,89,89))
        self.colorLeave = ((110,110,110))
        self.colorFont = ((131,131,131))
        self.SetBackgroundColour(self.colorLeave)
        self.SetForegroundColour(self.colorLeave)
        self.name = "Plugin"
        self.overPanel = 0
        self.overLabel = 0

        sizer = wx.BoxSizer(wx.VERTICAL)
        name = wx.StaticText(self, -1, ' ' + self.getName())
        close = wx.StaticText(self, -1, ' X ')

        gs = wx.GridSizer(2, 2, 0, 0)
        gs.AddMany([(name, 0, wx.ALIGN_LEFT), (close, 0, wx.ALIGN_RIGHT)])

        sizer.Add(gs, 1, wx.EXPAND)
        self.SetSizer(sizer)

        .... ....

是否可以左键单击 StaticText 关闭并隐藏面板本身？

Answer 1

我不知道是否可以将 wx.EVT_LEFT_DOWN 绑定到 StaticText 小部件。您可以使用按钮来调用 self.Hide()。如果您想要自定义外观，也许可以使用 BitmapButton。

class myPanel(wx.Panel):
    def __init__(self, parent, *args, **kwargs):
        wx.Panel.__init__(self, parent, *args, **kwargs)
        bitmap = wx.EmptyBitmap(15,15)
        self.button = wx.BitmapButton(self, -1, bitmap=bitmap, size=(15,15), style=wx.NO_BORDER)
        self.Bind(wx.EVT_BUTTON, self.onClick, self.button)

def onClick(self, event):
    self.Hide()

Answer 2

我似乎记得必须将静态文本放入框架或某些可以接收事件的对象内，但使其不可见。然后，文本上的单击事件将传递给父级。我曾经有一个用于可点击标签的特殊派生类。

Answer 3

您可以使用 EVT_LEFT_DOWN 或 EVT_LEFT_UP 来检测 StaticText 小部件上的鼠标操作

close.Bind(wx.EVT_LEFT_DOWN, self.hide_frame)

经过一天的努力，我找到了解决方案。 不可能从框架捕获鼠标事件，这些事件在 wxWidgets 中被故意丢弃。

您需要继承wxStaticText并在子对象中捕获鼠标事件。

/// Extend wxStaticText with a new capability of propagating mouse clicks.
class mouseStaticText: public wxStaticText
{
public:
    mouseStaticText(wxWindow *parent,
                 wxWindowID id,
                 const wxString& label,
                 const wxPoint& pos = wxDefaultPosition,
                 const wxSize& size = wxDefaultSize,
                 long style = 0,
                 const wxString& name = wxStaticTextNameStr): wxStaticText(parent, id, label, pos, size, style, name)
    {}

    void OnMouse(wxMouseEvent& event);

private:   
    DECLARE_EVENT_TABLE()
};

//declare external event notification when a camera resolution is changed.
BEGIN_DECLARE_EVENT_TYPES()    
  DECLARE_EVENT_TYPE(wxEVT_STATIC_TEXT_CLICKED, -1)
END_DECLARE_EVENT_TYPES()

BEGIN_EVENT_TABLE(mouseStaticText, wxStaticText)
    EVT_SYS_COLOUR_CHANGED(wxWindowMSW::OnSysColourChanged)
    EVT_ERASE_BACKGROUND(wxWindowMSW::OnEraseBackground)
    EVT_LEFT_DOWN(            mouseStaticText::OnMouse) 
#ifdef __WXWINCE__
    EVT_INIT_DIALOG(wxWindowMSW::OnInitDialog)
#endif
END_EVENT_TABLE()


/// Mouse click event needs to be propagated.
void mouseStaticText::OnMouse(wxMouseEvent& event)
{
    /* Emit notification about camera change. */
  wxCommandEvent NewEvent(wxEVT_STATIC_TEXT_CLICKED,GetId());
  NewEvent.SetEventObject(this);  
  //event.SetText( wxT("Camera") );  // Give it some contents (I hope that this is not necessary)
  GetEventHandler()->ProcessEvent(NewEvent);
}

然后你就可以正常捕获来自该对象的事件了

BEGIN_EVENT_TABLE(AboutDialog, wxDialog)
    EVT_PAINT(                AboutDialog::OnPaint)
    EVT_BUTTON(ID_BTN_OK,     AboutDialog::OnOk)
    EVT_COMMAND(ID_URL_TEXT, wxEVT_STATIC_TEXT_CLICKED, AboutDialog::OnClickURL)
    EVT_COMMAND(ID_ALT_URL_TEXT, wxEVT_STATIC_TEXT_CLICKED, AboutDialog::OnClickAltURL)
END_EVENT_TABLE()
