How to get the height of the entered text in a JTextPane?

由 折月煮酒 提交于 2019-12-22 10:59:24
问题 Is there a possible way to get the height of an entered text in a JTextPane ? Pixels would be great but any value that can represent it would do. For example I have entered in the JTextPane this: Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the

问题 Let me first describe the picture below: There are two printed papers. The only difference between them is that few space " " characters from paper in left are replaced by dot "." character in the paper in right. Red line represents the left border to which the text should be aligned Green curve represents my intention to align all characters it connects into a single column.

Styling text in a JTextArea or JTextPane

由 ▼魔方 西西 提交于 2019-12-22 01:53:57
问题 Basically, I have a JTextPane to hold some text which I wish to style. JTextArea would have been better for me to use but I'm told you cannot style the text in these? However, the JTextPane doesn't seem to style properly. For example, the following code is just returned with the HTML included: public static void main(String[] args) { JFrame j = new JFrame("Hello!"); j.setSize(200,200); JTextPane k = new JTextPane(); k.setText("<html><strong>Hey!</strong></html>"); j.add(k); j.setVisible(true)

Increasing the font size of a JTextPane that displays HTML text

由 ☆樱花仙子☆ 提交于 2019-12-21 20:27:15
问题 Lets say that I have a JTextPane that is showing a HTML document. I want that, on the press of a button, the font size of the document is increased. Unfortunately this is not as easy as it seems... I found a way to change the font size of the whole document, but that means that all the text is set to the font size that I specify. What I want is that the font size is increased in a proportional scale to what was already in the document. Do I have to iterate over every element on the document,

How to wrap text around components in a JTextPane?

由 妖精的绣舞 提交于 2019-12-19 19:55:18
问题 I don't understand the wrapping behavior in a JTextPane. If I insert a short text, then a JComponent and then again the short text I can see the inserted stuff in one line if the frame is large enough of course. But if the text is much longer so that it takes several lines the component is always placed in a new line. I have recognized that after a component has been inserted into a JTextPane its text gets longer by one character. So if a component is considered by a JTextPane as a character

How to prevent JScrollPane arrow key handling from moving caret when Scroll Pane wraps Text Pane

由 喜夏-厌秋 提交于 2019-12-19 11:54:31
问题 I have the following requirements: I need a scrollable JTextPane. The user may type into this text pane, or text may be inserted into it that is not typed by the user. Think something like an IM window. Although the window must be scrollable to allow the user to review text previously typed, the caret should never move from its position at the end of the text. Any text entered by the user will always appear at the end. In JTextPane, when the user scrolls with the scroll bar, the caret does
