一、MySlider控件

#include <wx/wx.h>

wxDECLARE_EVENT(MY_EVENT,wxCommandEvent);

class MySlider:public wxPanel
{
public:
? ? MySlider(wxPanel* parent);

protected:
? ? void m_slider_Scroll(wxScrollEvent& event);

? ? wxSlider* m_slider;

};
#endif // MYSLIDER_H_INCLUDED

wxDEFINE_EVENT(MY_EVENT,wxCommandEvent);

MySlider::MySlider(wxPanel* parent)
? ? :wxPanel(parent,wxID_ANY)
{
? ? m_parent = parent;

? ? m_slider = new wxSlider(m_parent,wxID_ANY
? ? ? ? ? ? ? ? ? ? ? ? ? ? ,75,0,750
? ? ? ? ? ? ? ? ? ? ? ? ? ? ,wxPoint(100,-1)
? ? ? ? ? ? ? ? ? ? ? ? ? ? ,wxSize(150,-1)
? ? ? ? ? ? ? ? ? ? ? ? ? ? ,wxSL_LABELS
? ? ? ? ? ? ? ? ? ? ? ? ? ? );

? ? m_slider->Bind(wxEVT_COMMAND_SLIDER_UPDATED
? ? ? ? ? ? ? ? ? ?,wxScrollEventHandler( MySlider::m_slider_Scroll)
? ? ? ? ? ? ? ? ? ?,this
? ? ? ? ? ? ? ? ? ?);
}

void MySlider::m_slider_Scroll(wxScrollEvent& event)
{

? ? wxCommandEvent ent(MY_EVENT);
? ? ent.SetEventObject(this);
? ? ent.SetInt(m_slider->GetValue());
? ? ent.SetString(wxString::Format("%i",m_slider->GetValue()));

// ? ?wxPostEvent(this,ent);

? ? ProcessWindowEvent(ent);
}
?

二、主程序

#include <wx/wx.h>
#include "mypanel.h"
#include "myslider.h"

class Simple:public wxFrame
{
public:
? ? Simple(const wxString& title);

? ? int GetCurWidth(){return cur_width;};

protected:
? ? void OnScroll(wxCommandEvent& event);

? ? wxPanel* panel;
? ? wxTextCtrl* tc;

? ? MyPanel* m_wid;
? ? MySlider* m_slider;

? ? int cur_width;

};

Simple::Simple(const wxString& title)
? ? :wxFrame(NULL,-1,title)
{
? ? cur_width = 75;

? ? panel = new wxPanel(this,wxID_ANY);
? ? wxPanel* topPanel = new wxPanel(panel,wxID_ANY);
? ? wxPanel* centerPanel = new wxPanel(panel,wxID_ANY);

? ? tc = new wxTextCtrl(topPanel,wxID_ANY);
? ? m_slider = new MySlider(centerPanel);
? ? m_slider->Bind(MY_EVENT,Simple::OnScroll,this);

? ? wxBoxSizer* vbox = new wxBoxSizer(wxVERTICAL);
? ? wxBoxSizer* hbox1 = new wxBoxSizer(wxHORIZONTAL);
? ? wxBoxSizer* hbox2 = new wxBoxSizer(wxHORIZONTAL);
? ? wxBoxSizer* hbox3 = new wxBoxSizer(wxHORIZONTAL);

? ? m_wid = new MyPanel(panel);
? ? m_wid->SetCurWidth(cur_width);

? ? hbox3->Add(topPanel,1,wxTOP|wxLEFT,35);
? ? hbox2->Add(centerPanel,1,wxEXPAND);
? ? hbox1->Add(m_wid,1,wxEXPAND);

? ? vbox->Add(hbox3,1,wxEXPAND);
? ? vbox->Add(hbox2,1,wxEXPAND);
? ? vbox->Add(hbox1,0,wxEXPAND);

? ? panel->SetSizer(vbox);

? ? Centre();
}

void Simple::OnScroll(wxCommandEvent& event)
{
? ? tc->SetLabel(event.GetString());

// ? ?cur_width = wxAtoi( event.GetString());
? ? cur_width = event.GetInt();

? ? m_wid->SetCurWidth(cur_width);
? ? m_wid->Refresh();

}
