问题 I am having trouble styling a JScrollPane. I just want to be able to change the color of both the thumb and the background (and also remove the increase/decrease buttons). So far I have tried the following: this.setBackground(new Color(0,0,0)); this.viewport.setBackground(new Color(0,0,0)); this.getViewport().setBackground(Color.BLACK); this.setOpaque(false); this.getVerticalScrollBar().setUI(new BasicScrollBarUI() { @Override protected JButton createDecreaseButton(int orientation) { return

问题 Is it possible to synchronize two scrolls? 回答1: Add this function to your code: jQuery.fn.synchronizeScroll = function() { var elements = this; if (elements.length <= 1) return; elements.scroll( function() { var left = $(this).scrollLeft(); var top = $(this).scrollTop(); elements.each( function() { if ($(this).scrollLeft() != left) $(this).scrollLeft(left); if ($(this).scrollTop() != top) $(this).scrollTop(top); } ); }); } Then, you can just synchronize all the scrollbars within an element

问题 The code that I have here is using a MouseAdapter to listen for the user to "draw" a box around the area of an image that they would like to zoom in on and calculate the ratio of the box to the image. It then resizes the image to the calculated ratio. This part works. The issue that I am having is making the JScrollPane view appear as if it is still at the same top left position after the image has been resized. I have tried several methods that seem to have gotten close to the result I want

I am asking how to fake it. 回答1: You could use JScrollPane.getViewport() to get the JViewport and add a ChangeListener to it. The JViewport will alert your listener when the size or, more

问题 Is there an easy way to create the arrows outside the jspcontainter and horizontally arranged for a vertical scroll bar? As the container has overflow:hidden with positioning the arrows cannot be displayed outside. I tried to clone the arrows with jquery clonefunction, but the js hangs up scrolling up again. Is there a way to add default-behavior to custom controls outside the container with the api? 回答1: The best way to do this would be to not show arrows on the jScrollPane itself and then
