    <p>Hi I am am trying to catch mouse movements for a MouseOver function in an app created with Code::Blocks using the wxSmith plugin. I have stumbled upon a puzzling problem. EVT_MOUSEWHEEL calling the function in the EventTable works well, but all other macros have no result at all. And the mousewheel is not <em>really</em> want I want (I just used it to test...) This is for Windows.</p> <p>Here is a the basic problem code (mostly generated by the <strong><em>fantastic</em></strong> wxSmith plugin) </p> <p>MouseMain.h</p> <pre><code>#include &lt;wx/frame.h&gt; #include &lt;wx/statusbr.h&gt; //*) class MouseFrame: public wxFrame { public: MouseFrame(wxWindow* parent,wxWindowID id = -1); virtual ~MouseFrame(); private: //(*Handlers(MouseFrame) void OnQuit(wxCommandEvent&amp; event); void OnAbout(wxCommandEvent&amp; event); void OnButton1Click(wxCommandEvent&amp; event); void MouseOver(wxMouseEvent&amp; event); //*) //(*Identifiers(MouseFrame) static const long ID_BUTTON1; static const long ID_STATICBITMAP1; static const long ID_PANEL1; static const long idMenuQuit; static const long idMenuAbout; static const long ID_STATUSBAR1; //*) //(*Declarations(MouseFrame) wxButton* Button1; wxStaticBitmap* StaticBitmap1; wxPanel* Panel1; wxStatusBar* StatusBar1; //*) DECLARE_EVENT_TABLE() }; #endif // MOUSEMAIN_H </code></pre> <p>...and MouseMain.cpp</p> <pre><code>#include "wx_pch.h" #include "MouseMain.h" #include &lt;wx/msgdlg.h&gt;

class MouseApp : public wxApp { public: virtual bool OnInit(); }; #endif // MOUSEAPP_H </code></pre> <p>So my big question: Why are EVT_MOTION, EVT_RIGHT_DOWN or EVT_RIGHT_DCLICK not calling MouseFrame::MouseOver(wxMouseEvent&amp; event) in the way EVT_MOUSEWHEEL does?</p>

    3. COTried compiling your code (on Vista), but I will need you to either remove the `mamail.jpg` image or post a link to it. Also, it would help if you posted the other 2 files (Probably called MouseApp.h & MouseApp.cpp or something)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
