jtextpane

问题 I have: HTMLDocument document = new HTMLDocument(); JTextPane htmlEditorPane = new JTextPane(document) htmlEditorPane.setContentType("text/html"); I then select some text in the middle of a sentence and call (wrapped in the appropriate ActionListeners): htmlEditorPane.copy(); htmlEditorPane.paste(); For whatever reason whenever I do this the text that is copy and pasted is wrapped in <p> tags.

问题 I want to find out which part of JTextPanel text is selected. Tried to call JTextPane.getSelectionStart() and JTextPane.getSelectionEnd() , but they always return same value that is equal to current caret position. What is my problem with that? I would be thankful for any code exapmle that gets current selection. 回答1: Have a look at JTextComponent#getSelectedText(). You'd simply call this method on the instance of your JTextPane and it will return the selected text of your JTextPane . Did a

问题 I am trying to create a text editor. I am using a JTextPane with a StyledDocument. What I am trying to implement is a way to change the attributes of selected text. This works in the following way : the user inputs the desired text. Afterwards, he can change any String's attributes (Font family, font size, whether it is bold/italic or not) by selecting it and pressing a button, where by means of checkboxes and dropdown lists would select the desired changes. Is it possible for me to change

问题 I have a JEditorPane that displays HTML that is generated programmatically (at runtime). Up to now when I was adding a "line" I was re-creating the whole HTML text in a string buffer and then passing it to JEditorPane.setText method.

The reason I try to append at the end is to avoid Swing (or the kit ?) having to render/parse the

问题 I have an application which continuously receives data on a socket, and then logs this data to a file while also displaying this data in a JTextPane. Naturally, as data is written to the underlying document of the JTextPane the memory usage continues to increase. Is there a simple way of limiting the memory which the JTextPane is allowed use? I would like the JTextPane to work similar to how a typical command shell's command history works. 回答1: just check the content and wipe it accordingly

问题 I want to build a console-like output using JTextPane. Therefore I am using a monospaced font: textpane.setFont(new Font(Font.MONOSPACED, Font.PLAIN, 12)); This works fine for all kind of alphanum (like a-z, 0-9 etc.) characters, but when it comes to symbols like ' \u2588 ' (█), the font isn't monospaced anymore. Did I forgot something? Or isn't there a monospaced font which includes smybols? 回答1: Ok, first off, it sounds to me like you're trying to address a couple of different things here,
