wxPython:消息对话框MessageDialog

Posted 2020-11-17 萌新上路

  wxMessageDialog(wxWindow* parent, const wxString& message, const wxString& caption = "Message box", long style = wxOK | wxCANCEL, const wxPoint& pos = wxDefaultPosition)

 

ShowModal()方法，它使用应用程序在对话框关闭前不能响应其它窗口的用户事件，返回一个整数，取值如下：

  wx.ID_YES, wx.ID_NO, wx.ID_CANCEL, wx.ID_OK。

 

style的取值主要有以下几种：

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, makes No button the default.
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).
