基于wxPython的GUI實(shí)現(xiàn)輸入對(duì)話框（2）

這篇文章主要為大家詳細(xì)介紹了基于wxPython的GUI實(shí)現(xiàn)輸入對(duì)話框的第二篇，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

接著上一篇基于wxPython的GUI輸入對(duì)話框1，繼續(xù)學(xué)習(xí)。

在程序輸入中，有時(shí)會(huì)要求同時(shí)改變多個(gè)參數(shù)值,而且類型也不盡相同,

這時(shí)TextEntryDialog就顯得不適用了.WxInput模塊則比較徹底的解決了這個(gè)問(wèn)題.

比如我有三個(gè)值要用戶交互式設(shè)置,一個(gè)是int數(shù),一個(gè)是str,一個(gè)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(guān)鍵是設(shè)置字典values的值.

WxInput會(huì)自動(dòng)根據(jù)字典values的內(nèi)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(gè)參數(shù)Method和num要設(shè)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:
