问题 StyledDocument contains various methods to set styles. Like setCharacterAttributes. But I can't see any methods to remove styles. Is there any? 回答1: It is impossible to "clear" styles. One should obtain a "default" style with the following technique: Style defaultStyle = StyleContext. getDefaultStyleContext(). getStyle(StyleContext.DEFAULT_STYLE); Then apply it with: sampleDocument.setCharacterAttributes(0, sampleDocument.getLength(), defaultStyle, true); 回答2: StyledDocument has a removeStyle

由 烂漫一生 提交于 2020-01-04 02:42:24
问题 What font does the StyledDocument associated with a JTextPane use? By default, does it use the same font as the JTextPane? In particular, I'm wondering about the font size. 回答1: StyledDocument is just interface. Interface doesn't have any font. If you take a look at the DefaultStyledDocument class (implementing the interface). public Font getFont(AttributeSet attr) { StyleContext styles = (StyleContext) getAttributeContext(); return styles.getFont(attr); } Then in the StyleContext's sources

问题 How exactly is word-wrapping implemented in JTextPane? I'm trying to understand exactly how it works so that I can modify the behavior. Right now, if I have a standard JTextPane inside a JScrollPane, it will break text at spaces, but not inside long words - if there is a string of text without spaces that is wider than the window, it won't wrap/break and a horizontal scrollbar will appear. As the text width increases, the width of the ParagraphView (via getWidth()) increases to hold the text.
