wxPython:訊息對話方塊MessageDialog
阿新 • • 發佈:2019-02-01
訊息對話方塊即我們平時說的Messagebox,看看它的原型,下面是wxWidgets中的原型定義,C++風格,與python風格的區別就是wx字首與後面名稱直接相連,例如wxMessageDialog,在wxpython中使用時就是wx.MessageDialog
wxMessageDialog(parent, message, caption = "Message box", long style = wxOK | wxCANCEL, pos = wxDefaultPosition)
其各引數不多做介紹,主要看看ShowModal()方法,它使用應用程式在對話方塊關閉前不能響應其它視窗的使用者事件,返回一個整數,取值如下:
wx.ID_YES, wx.ID_NO, wx.ID_CANCEL, wx.ID_OK。
另外,style的取值主要有以下幾種:
wxOK | Show an OK button. |
wxCANCEL | Show a Cancel button. |
wxYES_NO | Show Yes and No buttons. |
wxYES_DEFAULT | Used with wxYES_NO, makes Yes button the default - which is the default behaviour. |
wxNO_DEFAULT |
Used with wxYES_NO |
wxICON_EXCLAMATION | Shows an exclamation mark icon. |
wxICON_HAND | Shows an error icon. |
wxICON_ERROR | Shows an error icon - the same as wxICON_HAND. |
wxICON_QUESTION | Shows a question mark icon. |
wxICON_INFORMATION | Shows an information (i) icon. |
wxSTAY_ON_TOP | The message box stays on top of all other window, even those of the other applications (Windows only). |
還是看一個例子:
程式碼:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import wx
class MyFrame(wx.Frame):
def __init__(self, parent, id):
wx.Frame.__init__(self, parent, id, u'測試面板Panel', size = (600, 300))
#建立面板
panel = wx.Panel(self)
#在Panel上新增Button
button = wx.Button(panel, label = u'關閉', pos = (150, 60), size = (100, 60))
#繫結單擊事件
self.Bind(wx.EVT_BUTTON, self.OnCloseMe, button)
def OnCloseMe(self, event):
dlg = wx.MessageDialog(None, u"訊息對話方塊測試", u"標題資訊", wx.YES_NO | wx.ICON_QUESTION)
if dlg.ShowModal() == wx.ID_YES:
self.Close(True)
dlg.Destroy()
if __name__ == '__main__':
app = wx.PySimpleApp()
frame = MyFrame(parent = None, id = -1)
frame.Show()
app.MainLoop()
