本文实例讲述了wxpython中listbox用法。分享给大家供大家参考。具体如下：
# load a listbox with names, select a name and display in title# experiments with wxpython by vegaseat 20mar2005# python v2.4 and wxpython v2.5# if you have not already done so, install python 2.4 first.# i used python-2.4.1c2.msi (this is the self-extracting# ms-installer file) from http://www.python.org# then install wxpython2.5-win32-unicode-2.5.4.1-py24.exe# from: http://prdownloads.sourceforge.net/wxpython/# (if you don't get into unicode, download the ansi version)# note: python-2.4.1c2.msi should soon be python-2.4.1.msiimport wxdef create(parent): return frame1(parent)# assign id numbers[wxid_frame1, wxid_frame1button1, wxid_frame1button2, wxid_frame1listbox1, ] = [wx.newid() for _init_ctrls in range(4)]class frame1(wx.frame): def _init_ctrls(self, prnt): # boa generated methods wx.frame.__init__(self, id=wxid_frame1, name='', parent=prnt, pos=wx.point(358, 184), size=wx.size(299, 387), style=wx.default_frame_style, title=u'listbox test ...') self.setclientsize(wx.size(291, 347)) self.setbackgroundcolour(wx.colour(0, 128, 0)) self.button1 = wx.button(id=wxid_frame1button1, label=u'load listbox', name='button1', parent=self, pos=wx.point(8, 8), size=wx.size(176, 28), style=0) self.button1.bind(wx.evt_button, self.onbutton1button, id=wxid_frame1button1) self.listbox1 = wx.listbox(choices=[], id=wxid_frame1listbox1, name='listbox1', parent=self, pos=wx.point(8, 48), size=wx.size(184, 256), style=0) self.listbox1.setbackgroundcolour(wx.colour(255, 255, 128)) self.listbox1.bind(wx.evt_listbox, self.onlistbox1listbox, id=wxid_frame1listbox1) self.button2 = wx.button(id=wxid_frame1button2, label=u'clear', name='button2', parent=self, pos=wx.point(104, 312), size=wx.size(87, 28), style=0) self.button2.bind(wx.evt_button, self.onbutton2button, id=wxid_frame1button2) def __init__(self, parent): self._init_ctrls(parent) def onbutton1button(self, event): ''' click button to load the listbox with names ''' self.listbox1.append(andreas) self.listbox1.append(erich) self.listbox1.append(udo) self.listbox1.append(jens) self.listbox1.append(bjorn) self.listbox1.append(heidrun) self.listbox1.append(ulla) self.listbox1.append(volger) self.listbox1.append(helmut) self.listbox1.append(freja) self.settitle(select a name ...) def onlistbox1listbox(self, event): ''' click list item and display the selected string in frame's title ''' selname = self.listbox1.getstringselection() self.settitle(selname) def onbutton2button(self, event): ''' click button to clear the listbox items ''' self.listbox1.clear()#--------------- end of class frame1 --------------------# program entry point ...if __name__ == '__main__': app = wx.pysimpleapp() wx.initallimagehandlers() frame = create(none) frame.show() app.mainloop()
