這篇文章將為大家詳細講解有關基于wxPython的GUI如何實現輸入對話框,小編覺得挺實用的,因此分享給大家做個參考,希望大家閱讀完這篇文章后可以有所收獲。
在程序輸入中,有時會要求同時改變多個參數值,而且類型也不盡相同,
這時TextEntryDialog就顯得不適用了.WxInput模塊則比較徹底的解決了這個問題.
比如我有三個值要用戶交互式設置,一個是int數,一個是str,一個是float,先看示例文件:
from WInput import InputBox values={'int':1,'String':'This is String','float':3.5} title='Setting values:' rvalues=InputBox(title,values) print(rvalues)
顯示GUI如下:
上面的代碼的關鍵是設置字典values的值.
WxInput會自動根據字典values的內容生成輸入界面,
而且返回值的類型確保和原始類型一樣.
再比如程序中有任意兩個參數Method和num要設置,那么如下就可了:
title='Setting values:' values={'Method':'LogLog','Value':3.5} rvalues=InputBox(title,values)
生成的界面如下:
WxInput模塊的代碼如下:
