Mostapplications are rectangular. They share lots of similarities.They have menus, toolbars, titles etc. This might be boring.Some developers create more fancy applications. We canmake our applications more attractive by using images. Theidea is as follows. We create a frame without a border. We candraw a custom image on the frame during the paint event.wx.Frame.__init__(self, parent, id, title,style=wx.FRAME_SHAPED |wx.SIMPLE_BORDER |wx.FRAME_NO_TASKBAR)In order to create a custom shaped application, we must setnecessary style options. The wx.FRAME_SHAPED enables tocreate a shaped window. The wx.SIMPLE_BORDER removesthe thick border. The wx.FRAME_NO_TASKBAR prevents theapplication from appearing on the taskbar.self.font = wx.Font(11, wx.FONTFAMILY_DEFAULT, wx.FONTSTYLE_NORMAL,wx.FONTWEIGHT_BOLD, False, 'Comic Sans MS')I was looking for a nice font for the note example. I finallychose Comic Sans MS. This is a proprietary font. Linux usersmust install msttcorefonts package. If we do not have a font41 de 44 27/04/2008 1:08
