Wxpython向导wx.adv.Wizard组件
前言
在界面程序主界面显示前,向导界面会引导用户初始化和配置其他数据,wxpython提供了wx.adv.Wizard,可参考:
文档:https://wxpython.org/Phoenix/docs/html/wx.adv.Wizard.html
Demo实现
import wx import wx.adv class configWizard(wx.adv.Wizard): def __init__(self, addNew = False): super(configWizard, self).__init__(None, -1, "Configuration Wizard") self.Bind(wx.adv.EVT_WIZARD_PAGE_CHANGED, self.OnPageChanged) self.Bind(wx.adv.EVT_WIZARD_PAGE_CHANGING, self.OnPageChanging) self.firstInfoPage = Info1Page(self,'title1') self.machineSelectPage = Info2Page(self,'title2') wx.adv.WizardPageSimple.Chain(self.firstInfoPage, self.machineSelectPage) # self.GetPageAreaSizer().Add(self.firstInfoPage) self.RunWizard(self.firstInfoPage) self.Destroy() def OnPageChanging(self, e): print(e.GetPage()) # e.GetPage().StoreData() def OnPageChanged(self, e): if e.GetPage().AllowNext(): self.FindWindowById(wx.ID_FORWARD).Enable() else: self.FindWindowById(wx.ID_FORWARD).Disable() if e.GetPage().AllowBack(): self.FindWindowById(wx.ID_BACKWARD).Enable() else: self.FindWindowById(wx.ID_BACKWARD).Disable() class Info1Page(wx.adv.WizardPageSimple): def __init__(self, parent, title): wx.adv.WizardPageSimple.__init__(self, parent) sizer = wx.GridBagSizer(5, 5) self.sizer = sizer self.SetSizer(sizer) title = wx.StaticText(self, -1, title) title.SetFont(wx.Font(18, wx.SWISS, wx.NORMAL, wx.BOLD)) sizer.Add(title, pos=(0, 0), span=(1, 2), flag=wx.ALIGN_CENTRE | wx.ALL) sizer.Add(wx.StaticLine(self, -1), pos=(1, 0), span=(1, 2), flag=wx.EXPAND | wx.ALL) sizer.AddGrowableCol(1) def AllowNext(self): print(1) return True def AllowBack(self): print(2) return False class Info2Page(wx.adv.WizardPageSimple): def __init__(self, parent, title): wx.adv.WizardPageSimple.__init__(self, parent) sizer = wx.GridBagSizer(5, 5) self.sizer = sizer self.SetSizer(sizer) title = wx.StaticText(self, -1, title) title.SetFont(wx.Font(18, wx.SWISS, wx.NORMAL, wx.BOLD)) sizer.Add(title, pos=(0, 0), span=(1, 2), flag=wx.ALIGN_CENTRE | wx.ALL) sizer.Add(wx.StaticLine(self, -1), pos=(1, 0), span=(1, 2), flag=wx.EXPAND | wx.ALL) sizer.AddGrowableCol(1) def AllowNext(self): print(1) return True def AllowBack(self): print(2) return True class Example(wx.Frame): def __init__(self, *args, **kw): super(Example, self).__init__(*args, **kw) configWizard() self.InitButton() self.SetSize((300, 200)) self.SetTitle('wx.Gauge') self.Centre() self.Show(True) def InitButton(self): pnl = wx.Panel(self) self.btn1 = wx.Button(pnl, label="Start") self.Bind(wx.EVT_BUTTON, self.OnStart, self.btn1) def OnStart(self, e): pass def main(): ex = wx.App() Example(None) ex.MainLoop() if __name__ == '__main__': main()
相关代码详解
继承向导类
每一个向导page类都要继承wx.adv.WizardPageSimple,其中有两个函数必须实现:
- AllowNext
- AllowBack
如果此向导界面页面后还有其他向导界面则AllowNext为True,反之为False,AllowBack表示此页面可以后退,但第一个向导界面不可设置为True。
链接多个向导界面
使用wx.adv.WizardPageSimple.Chain()可以将两个向导page前后关联起来,如果有多个page,同样如此。
事件
当向导界面发生改变时(切换界面,点击finsh)会触发事件,提供了如下事件:
当界面内容正在更改,可通过事件参数获取到正在更改的界面,然后调用其对象(函数)对数据进行处理。
