def __init__(self, parent, id, bmp, text, **kwargs):
wx.PyControl.__init__(self,parent, id, **kwargs)
self.Bind(wx.EVT_LEFT_DOWN, self._onMouseDown)
self.Bind(wx.EVT_LEFT_UP, self._onMouseUp)
self.Bind(wx.EVT_LEAVE_WINDOW, self._onMouseLeave)
self.Bind(wx.EVT_ENTER_WINDOW, self._onMouseEnter)
self.Bind(wx.EVT_ERASE_BACKGROUND,self._onEraseBackground)
self.Bind(wx.EVT_PAINT,self._onPaint)
self._mouseIn = self._mouseDown = False
def _onMouseEnter(self, event):
self._mouseIn = True
def _onMouseLeave(self, event):
self._mouseIn = False
def _onMouseDown(self, event):
self._mouseDown = True
def _onMouseUp(self, event):
self._mouseDown = False
self.sendButtonEvent()
def sendButtonEvent(self):
event = wx.CommandEvent(wx.wxEVT_COMMAND_BUTTON_CLICKED, self.GetId())
event.SetInt(0)
event.SetEventObject(self)
self.GetEventHandler().ProcessEvent(event)
def _onEraseBackground(self,event):
# reduce flicker
pass
def _onPaint(self, event):
dc = wx.BufferedPaintDC(self)
dc.SetFont(self.GetFont())
dc.SetBackground(wx.Brush(self.GetBackgroundColour()))
dc.Clear()
# draw whatever you want to draw
# draw glossy bitmaps e.g. dc.DrawBitmap
if self._mouseIn:
pass# on mouserover may be draw different bitmap
