问题 I'm trying to create a button with only the first letter underlined. Obviously I can not use tags , then I would realize it with css, by using the pseudo element :first-letter. It works very well in other contexts, but in button doesn't work. There are other solutions? 回答1: Since you haven't shared your code, I'll take a bold guess here. You're using <input type="button" value="Some Value"> , because there's no actual text inside (The displayed text comes from the value= attribue), :first

问题 I have a problem keeping the state of my buttons - say Button1.setActivated(true) . When orientation is changed this is forgotten and it is not reactivated or shown as activated. I guess I could use IFs to test the status of Button state, store it in a variable and then return it with onSaveInstanceState/onRestoreInstanceState. And then add more checks on each button when it is recreated. But that seems a massive convoluted way of doing things. Surely there will be a better way to do this? I

问题 I have done research and I haven't found solution for my problem. Is there any good way, to disable minimize, maximize and close buttons in Win32 ? I want them to be still present and animating but not sensitive. I want also to be able to resize the window by dragging the frame. 回答1: Simply capture the relevant events (WM_SYSCOMMAND and WM_CLOSE), and tell Windows to ignore them by returning 0. Please note that in case of WM_SYSCOMMAND, you should only do this for events you really want to

问题 I think this is more of a python question, then a kivy question. class Keyboard is sharing a method from class GUI.
