jscrollpane

问题 I have a JTabbedPane which two tabs including two JScrollPane . Each JScrollPane is including a JEditorPane . If there is no image in the editor, there is no problem. When there is an image, the scroll does not go down to follow the caret position for the first editor, it's like the image gains always the caret beside it after loading at the end of loading the editor.. Here is my code: public class CaretPositionForJEditorPane { JTabbedPane tabs; JScrollPane scrollPane1; JEditorPane editor1;

问题 I can see right now the scrolling priority is given to vertical scrolling. I want to change that. How do I do that? 回答1: Thanks to the first answer- very helpful. However I found that iNewValue in the response above needs to be multiplied by the evt.getWheelRotation() value which is the number of distinct wheel mouse segments actually rotated by the wheel mouse. Also the condition of when to scroll needs to take account of this as well - the condition has to be evt.getWheelRotation() <= -1 or

问题 I have a JScrollPane and a JPanel inside. I see the scrollbars when needed, but the mouse wheeling works only when the mouse is over the scrollbars. Is there a property or something to make mouse wheeling work when the mouse pointer is over the whole panel, not just the scrollbars? You know like in browsers - you can scroll the page even if the mouse pointer is not over the scrollbars. Thanks in advance! 回答1: It works for me (Java 6, Windows, JScrollPane containing a JPanel, mouse wheeling

问题 I need to handle event from JScrollPane when user scrolls it. In here it is suggested to use addAdjustmentListener to either JViewport or Vertical/HorizontalScrollBar. Is there any difference, which method should I choose? I would like also to use scrollRectToVisible for the same JScrollPane , should I anticipate AdjustmentListener working for this method? Also I wonder whether scrollRectToVisible tries to do minimum scrolling to make required rectangular visible or it tries to make it

问题 I am using Miglayout to define a layout for my program. The problem is the JScrollPane prevents the JButton shrinking below its preferred size. The minimum, preferred, and maximum widths for the JButton are set like this, "w 300:600:900" //min:pref:max . What is the best way to fix this problem?

The scroll bars appear but the graphics do not show. import java.awt.Dimension; import java.awt.Graphics; import java.awt.Graphics2D; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JScrollPane; public class Test extends JPanel{ public static void main(String... args) { Test test = new Test(); JFrame frame = new

问题 I have a JList that is inside of a JscrollPane and I am trying to do some pagination on the data, in which as the user scrolls it loads the appropriate amount of data onto the screen. The problem is I need to figure out how much data I need to buffer out of my file and the only way to do that is to figure out how much data needs to be displayed on the screen. Does anyone have an idea of how to get the number or rows and columns that can be displayed out of my JList ? Also is doing pagination

问题 This question is related to a previous answered question which can be found here: Jquery jscrollpane width to adjust automatically according to content Thanks to user Mac who has provided the following solution: JS should look like below: $(function(){ var totalImages = $("#images img").length; var imgWidth = 661 + 5; //width of an image plus the margin $("#imagesContainer").css("width",totalImages*imgWidth - 5); $('.scroll-pane').jScrollPane({ showArrows: true, autoReinitialise: true }); });

问题 I cannot make this work for some reason. I want jscrollpane to be used in an unordered list (ul). I have managed to do this by itself but when used with a nested ul it does not seem to work. I have uploaded my example to jsFiddle so anyone can take a look and fiddle around.

Here it is on the right question: You shouldn't apply jScrollPane directly to a UL. Because

问题 I have a question in relation to adding components to a Java frame. I have a JPanel with two buttons and also a JScrollPane that has a JTable added to it. I am wanting to add both these to a JFrame. I can add either the JPanel to the JFrame, or the JScrollPane to the JFrame and they display correctly.
