JScrollPane adjustmentListener and scrollRectToVisible

由 戏子无情 提交于 2019-12-11 05:53:47
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 have the following line of code: JSplitPane VPane = new JSplitPane(JSplitPane.VERTICAL_SPLIT,(new class1()),new JScrollPane(new class2())); I'd like class2 to ONLY have vertical scrolling please?

It doesn't seem to work- I'm just getting errors =[ To illustrate this: JScrollPane js=...; //Create a variable reference to the

java coloured scroll bar search result

由 拜拜、爱过 提交于 2019-12-04 14:11:03
问题 How would I go about customizing a scroll bar in Java so that I could have a search that acts like chrome, that's to say puts coloured stripes where the results are? I don't want a library as I'd prefer to code it myself. Plus I don't want to loose my L&F that I have. Examples welcome. Actually it will be to view a large text file or a long jtable, and does anyone have any good ideas for how I could have an efficient scroll bar to view this? ... should I have a double scroll bar one beginning

I'm having trouble getting JScrollPanes to actually display scroll bars

由 孤街浪徒 提交于 2019-12-01 23:34:41
问题 I've found some examples scattered around the internet involving getting an image or a textbox to display scroll bars, but they all involve a program that basically displays its entire contents in a scroll pane. What I need to get it to do is stick a JPanel somewhere, pile a bunch of text, icons, etc into that panel until its too big for the space I've got for it, and then scroll across it. I'm probably going to need to be able to null-layout that panel, too, because I'm probably going to

How to know if a JScrollBar has reached the bottom of the JScrollPane?

由 情到浓时终转凉″ 提交于 2019-12-01 18:28:45
I'd like to know if there is a way to know when a JScrollBar (vertical in my case) has reached the bottom of his containing JScrollPane . At first i have though of using an AdjustmentListener on the scroll bar but i don't know how to interpret the value attribute of the JScrollBar . Also i'm not sure to properly understand what the maximum represents and if i can use with the value to get the information i need. Edit : scrollPane.getVerticalScrollBar().addAdjustmentListener(new AdjustmentListener() { @Override public void adjustmentValueChanged(AdjustmentEvent ae) { System.out.println("Value:
