TKinter之输入框 输入框是 Entry，应用程序要取得用户的信息，输入框是必不可少的。 输入框比较重要的一个函数： 　　get:返回值即输入框的内容 　　比如e是一个输入框，e['show']='*'就变成了密码框 小例子：用户登陆窗口，成功失败均有返回 示例代码 #!/usr/bin/env python # _*_ coding:utf-8 _*_ from Tkinter import * root = Tk() #按扭调用的函数， def reg(): User = e_user. get () Pwd = e_pwd. get () len_user = len(User) len_pwd = len(Pwd) if User== '111' and Pwd == '222' : l_msg[ 'text' ]= '登陆成功' else : l_msg[ 'text' ]= '用户名或密码错误' e_user.delete(0,len_user) e_pwd.delete(0,len_pwd) #第一行，用户名标签及输入框 l_user =Label(root,text= '用户名：' ) l_user.grid(row=0,sticky=W) e_user =Entry(root) e_user.grid(row=0,column=1,sticky=E) #第二行

Is it possible to have multiple sticky elements stacked on top of each other in pure CSS? The desired behavior can be seen here: https://webthemez.com/demo/sticky-multi-header-scroll/index.html Only I'd prefer to use pure CSS, instead of a Javascript implementation. I've experimented a bit with multiple sticky elements, but I can't keep them from pushing out other sticky elements. I've tried placing them in the same stacking context: #sticky .sticky-1, #sticky .sticky-2 { position: sticky; } #sticky .sticky-1 { top: 1em; z-index: 1; } #sticky .sticky-2 { top: 2em; z-index: 1; } But can't get

I am using this plugin to achieve a sticky Table Header in my Table . Actually as in the plugin example and in my page, the table Header disappear a bit later the last row in the table. I want my table header disappearing exactly when the last row is gone.There is a chance to achieve that? here's a working example: fiddle all I changed was the end of this line: if ((scrollTop > offset.top) && (scrollTop < offset.top + $this.height()-base.$clonedHeader.height())) { You could add a bug report on github: https://github.com/jmosbech/StickyTableHeaders/issues I know this is old, but I felt like

Well, this is my first post here and really enjoying the site. I have a very basic (ugly as sin) site I have started and for some reason, I can not get the CSS Sticky footer to work for FireFox.

Can anyone help put me out of my misery please? Thanks, guys and gals. Try this one , it works well on Firefox. BTW, you should listen to Boagworld's podcast if you

I notice that applications like Skype use a service which basically runs 24x7, without getting killed at all. You cannot even manually kill it using task killers ( you can kill them by going to running services and kill service ). How is this implemented? I find that in Android 2.3, my service gets killed after running for sometime. onDestroy() is never called even if I start the service with START_STICKY. However this works fine on my 2.1 device, that is the service doesnt get killed. Thanks How is this implemented? Based on the Skype screenshots that show a Notification icon, then they are

The new value of position is very confusing to me.. a lot of search result give javascript/jQuery (JavaScript-framework) solutions. In the example in bottom i have a table with a thead and tbody . No matter what i cannot achieve the desire result. Desire result is thead to be sticky to the table. sticky means when not in view the element is some kind of position:fixed fixed means it sticks to your screen.
