如何为JSplitPane设置自定义分隔符

Question

我发现了这个例子:

http://java2s.com/Open-Source/Java-Document-2/Swing/petersoft-java-style-2/com/petersoft/white/SplitPaneDivider.java.htm

我想把它应用到我的JSplitPane

所以我做了:

BasicSplitPaneUI bspUI=(BasicSplitPaneUI)mainContainer.getUI();
mainContainer.setUI(new ola.elementsCustom.SplitPaneDivider(bspUI));

但是它给了我一个错误，我真的不明白:

setUI() (ola.elementsCustom.SplitPaneDivider)没有合适的方法方法javax.swing.JSplitPane.setUI(javax.swing. platform . splitpaneui)是不适用的…

Answer 1

ola.elementsCustom.SplitPaneDivider需要扩展javax.swing.plaf.SplitPaneUI -您确定是这样吗?

无论如何，你总是可以修改分隔符的外观和行为，比如:

splitPane.setUI(new BasicSplitPaneUI() {
            public BasicSplitPaneDivider createDefaultDivider() {
                return new BasicSplitPaneDivider(this) {
                    public void setBorder(Border b) {
                        //some code
                    }
                };
            }
        });
