How to get a JTextField to respond to the enter key

由 ℡╲_俬逩灬. 提交于 2019-12-18 09:05:07
问题 So I want to get a JTexField to put the text in it into a JTextArea when the enter key is pressed with the cursor in it. Can anyone help? 回答1: Forget about using KeyListener for Swing components. This listener was designed for use with AWT components does not provide a reliable interaction mechanism for JTextComponents . Use an ActionListener instead - on the vast majority of systems an ActionEvent is dispatched by the JTextField when enter is pressed. myTextField.addActionListener(new

contentEditable - Firefox <br /> tag

问题 Firefox inserts a <br /> tag on press enter whereas the other browsers are adding either a <p> or <div> . I know that chrome and safari are inserting the same tag of the firstchild of the contentEditable div. So do Firefox, however, if the first tag's innerHTML is empty firefox is just ignoring the tag and creating a new line by pushing the default node in the second line and writes directly inside the editor instead of inside a child node. So basically, I want Firefox to write inside the

The .val() of a textarea doesn't take new lines into account

由 纵饮孤独 提交于 2019-12-17 09:45:17
问题 The .val() property of an item in jQuery for a <textarea> doesn't seem to work with new lines. I need this function as the text-area is meant to recognize the enter key and display it as a preview, with the new line in tact. However, what happens is shown in this fiddle: http://jsfiddle.net/GbjTy/1/. The text is displayed, but not in a new line. How can I achieve the preview to include new lines, and I know it is possible, because it does this in the Stack Overflow Post Question preview.

在linux环境下编写C程序

在linux环境下编写C程序 在linux环境下编写C程序一般使用文本编辑器vim，vim是linu下的老牌编辑工具vi的升级版本，其功能更加强大，更适合用来 编辑C程序。在一些linux的发行版本如deepin等都是自带vi的，用户可以直接使用；而在另一些发行版本如ubuntu等则是 只有vi而没有vim的，这时候就需要我们自己去完成vim的安装。 vim的安装：在ubuntu系统下同时使用`ctrl----alt----t`打开终端，并在终端上输入命令`vim enter`系统会提示找不到命令， 这时就可以按照系统的提示输入`sudo apt-get install vim-gtk`enter系统会让你选择是否继续执行命令，输入`y`,选择继续执 行，然后就可以等待vim安装完成。 待vim安装完成之后，在终端输入`vim` 文件名`enter`就可 创建一个文件，在这里我们需要编写C程序，所以要把文件名 后缀改成.c，即输入`vim 文件名.c`enter就代表创建了一个C序源文件。这时就会进入vim的编辑界面，并且是vim的命令模 式。在这个模式下，我们可以使用一些vim的专属命令来对件进行修改，且在此模式下，所键入的字符都会算作命令而不 会作为文本内容。此时输入`i`命令进入插入模式，在此模式下可以对文本进行编辑，此时所输入的内容都会被看作字符即文 本内容
