wxWidgets自定义按钮的方法
场景:
1.现在的软件上的按钮都不是标准的按钮了，因为基本上是贴图上去的，正常情况下一种图片，鼠标移上去之后按钮显示另一种效果，按下去之后又是另一种效果。
2.wx的做法其实和mfc的按钮原理是一样的，就是给按钮贴图和重绘背景。
以下是源文件.

调用方式和wxButton一样.
1.先注册事件映射宏.
EVT_BUTTON(Minimal_StartSimplePopup,MyFrame::OnStartSimplePopup)
2.调用代码.
wxBitmap*normal=newwxBitmap("./resources/start/start_normal.png",
wxBITMAP_TYPE_PNG);
wxBitmap*down=newwxBitmap("./resources/start/start_pressed.png",
wxBITMAP_TYPE_PNG);
wxBitmap*enter=newwxBitmap("./resources/start/start_current.png",
wxBITMAP_TYPE_PNG);
wxBitmap*disable=newwxBitmap("./resources/start/stop_normal.png",
wxBITMAP_TYPE_PNG);
wxBitmapbg=GetPositionBackgroundBitmap(0,0,normal->GetWidth(),normal->GetHeight());
start=newDhBitmapButton(page,Minimal_StartSimplePopup,wxPoint(0,0),
normal->GetSize());
start->set_normal_bitmap(normal)->set_down_bitmap(down)->set_enter_bitmap(enter);
start->set_disable_bitmap(disable);
start->set_background(bg);
wxBitmapMyFrame::GetPositionBackgroundBitmap(intx,inty,
intwidth,intheight)
{
wxRectrect;
rect.x=x;
rect.y=y;
rect.width=width;
rect.height=height;
wxBitmaptemp=this->bg.GetSubBitmap(rect);
returntemp;
}
3.当然我觉得有更好的方式.
比如重载这个类.wxBit
