1. what's wrong with this program

#3367

Posted by: 2004-02-14 10:35:25

I wanted to create frame with window and textctrl, when user clicked on the window or the textctrl the messagebox had to appear. So I did this like that.
First I put definition of the class myevt in the header file:


class myevt : public wxEvtHandler
{
  public:
            void Mouse(wxMouseEvent&);  // that is the function with message
  private:
    DECLARE_EVENT_TABLE();
};

Then In my cpp file I wrote an implementation of this class


BEGIN_EVENT_TABLE(myevt, wxEvtHandler)
    EVT_LEFT_DOWN(myevt::Mouse)
END_EVENT_TABLE()

void myevt::Mouse(wxMouseEvent& event)
{
  wxMessageBox("dsfs", "sdfs", wxOK);
}

In the constructor of the frame I created one window and textctrl and of course evt. Everything looked like below:


evt = new myevt();
w3 = new wxWindow(this, -1, wxPoint(220, 120), wxSize(100, 100),        
                                   wxSIMPLE_BORDER);
w3->PushEventHandler(evt);

t1 = new wxTextCtrl(this, -1, "cbcbxcbxcvbxcvbbxcb", wxPoint(20, 100),
                                 wxSize(100, 100), wxTE_MULTILINE | 
                                 wxNO_FULL_REPAINT_ON_RESIZE);
t1->PushEventHandler(evt);

And when I compiled this program the window was transparent, but not on the whole area. And I have no idea why, does anybody know. I use winxp, maybe on other systems this program works correctly ?

Hi!
Not sure what causes this problem, but try it like this:


w3 = new wxWindow(this, -1, wxPoint(220, 120), wxSize(100, 100),        
                                   wxSIMPLE_BORDER);
w3->PushEventHandler(new myevt());

t1 = new wxTextCtrl(this, -1, "cbcbxcbxcvbxcvbbxcb", wxPoint(20, 100),
                                 wxSize(100, 100), wxTE_MULTILINE | 
                                 wxNO_FULL_REPAINT_ON_RESIZE);
t1->PushEventHandler(new myevt());

Works for me showing the window with a standard grey background.

The most frustrating is that everything works fine until You add a wxTextCtrl object to the program and push event handler like this
