我想知道如何在状态栏中添加按钮用途的描述。
我一直认为这是这样的 -
self.SetStatusText("text", btn1)
然而它似乎不起作用。
我让它用于显示窗口的名称,以及菜单栏操作的说明。但我无法让它为Button工作。
例如在菜单栏中 -
Settings = goto.Append(wx.NewId(), "Settings", "Navigate to Settings Window")
似乎按钮没有“附加”属性。

提供用户帮助的最常用方法是使用工具提示:
import wx
class MainWindow(wx.Frame):
def __init__(self, *args, **kwargs):
wx.Frame.__init__(self, *args, **kwargs)
self.CreateStatusBar()
self.panel = wx.Panel(self)
self.button = wx.Button(self.panel, label="Test")
self.button.SetToolTipString("This is for testing purposes!")
self.sizer = wx.BoxSizer()
self.sizer.Add(self.button)
self.panel.SetSizerAndFit(self.sizer)
self.Show()
app = wx.App(False)
win = MainWindow(None)
app.MainLoop()
如果您坚持使用StatusBar,则可以绑定EVT_ENTER_WINDOW和EVT_LEAVE_WINDOW。一个小例子:
import wx
class TipButton(wx.Button):
"""Subclass of wx.Button, has the same functionality.
Allows user to set Status Bar help by using SetStatusText method.
"""
current = None
def __init__(self, *args, **kwargs):
wx.Button.__init__(self, *args, **kwargs)
def SetStatusText(self, help_string, status_bar_frame):
self.help_string = help_string
self.status_bar_frame = status_bar_frame
self.Bind(wx.EVT_ENTER_WINDOW, self._ShowHelp)
self.Bind(wx.EVT_LEAVE_WINDOW, self._HideHelp)
def _ShowHelp(self, e):
TipButton.current = self.GetLabel()
self.status_bar_frame.SetStatusText(self.help_string)
def _HideHelp(self, e):
if self.GetLabel() == TipButton.current:
self.status_bar_frame.SetStatusText("")
class MainWindow(wx.Frame):
def __init__(self, *args, **kwargs):
wx.Frame.__init__(self, *args, **kwargs)
self.CreateStatusBar()
self.panel = wx.Panel(self)
# Instead of
# self.button1 = wx.Button(self.panel, label="Test1", size=(150, 50))
self.button1 = TipButton(self.panel, label="Test1", size=(150, 50))
self.button1.SetStatusText("This is for testing purposes", self)
self.button1.SetFont(wx.Font(14, wx.DEFAULT, wx.NORMAL, wx.NORMAL, 0, u'Consolas'))
# Instead of
# self.button2 = wx.Button(self.panel, label="Test2", size=(150, 50))
self.button2 = TipButton(self.panel, label="Test2", size=(150, 50))
self.button2.SetStatusText("This is jusst for fun!", self)
self.button2.SetFont(wx.Font(14, wx.DEFAULT, wx.NORMAL, wx.NORMAL, 0, u'Consolas'))
self.sizer = wx.BoxSizer()
self.sizer.Add(self.button1)
self.sizer.Add(self.button2)
self.panel.SetSizerAndFit(self.sizer)
self.Show()
app = wx.App(False)
win = MainWindow(None)
app.MainLoop()
