jscrollpane

问题 I've been having trouble trying to get the table to scroll; it just won't.

问题 i have a jscrollpane added to jtabbedpane and inside the jscrollbar pane i have a jpanel. In the jpanel i have few buttons which i am creating on runtime. My idea is it get a scroll bar when the button size that i am adding dynamically during runtime grows. I cant get that to happen. The button size is increased and it hides when the size goes beyond the jpanel's view. I am increasing the size of jpanel and the buttons inside it using setSize(). I have also used jScrollPane2.setViewportView

问题 I get this error when I try and implement jSrollpane in Safari 4: TypeError: Result of expression '$drag[0]' [undefined] is not an object. Then i get this error when i try the same thing in Chrome: Uncaught TypeError: Cannot read property 'offsetHeight' of undefined But why? it works fine in FF. Any ideas? 回答1: It appears that jQuery does not manage to resolve the child selector (“parent > child”), thus both "$track" and "$drag" are set to undefined values: $track = $('>.jScrollPaneTrack',

问题 Strugglig a bit with what seems to be a margin issue with jScrollPane. Tried setting margin: 0 pretty much on every element that's inside the jsp and on the actual jsp elements. I'm attaching a picture to show you the issue. The problem is the small black stripe between the content and the actual scrollbar. CSS for classes inside JSP width: 100%; min-height: 60px; max-height: 300px; margin: 0; padding: 0; CSS for JSP .jspContainer { overflow: hidden; position: relative; } .jspPane { position:

问题 I want to implement a Scrollbar onto my Tab. However nothing is showing and there are no exceptions. I think I need a: scrollPane.setViewportView(scrollPanel); But it didn't work as well. I am wondering when adding a Jscrollpane onto a JTab how do you set it visible without using an explicit frame. If I use a frame and add it on the frame it creates a new window.

问题 I need to fit a huge image (BufferedImage to access colors etc) into a JScrollPane derived class. Nothing very hard until there. The image is a JPG scan of an A3 sample of material, its size is 13030x20840 pixels, 24bits, and weights 12MB on disk -> about 800MB in RAM.

I need your help in order to know what I should do to

问题 scrollPane = new JScrollPane(table); panel1.add( scrollPane,BorderLayout.CENTER ); Is there a way I can make the scrollPane bigger (wider) ? 回答1: JScrollPane scrollPane = new JScrollPane(table, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_NEVER); JScrollBar bar = scrollPane.getVerticalScrollBar(); bar.setPreferredSize(new Dimension(40, 0)); This works.

问题 How to Split Component vertically into different parts? Is It possible in Swing?
