问题描述
我有一个Java按钮，可以打开JColorChooser对话框。我希望按钮的颜色根据对话框中选择的颜色进行更改。我试过调用按钮的setBackgroundColor（）方法，但在我的情况下它没有效果（按钮在Winsows 7中的JToolBar上）。另外，问题建议更改按钮的背景不是平台独立的。
I have a Java button that opens a JColorChooser dialog. I would like for the color of the button to change according to the color selected in the dialog. I have tried calling the setBackgroundColor() method of the button, but in my case it has no effect (the button is on a JToolBar in Winsows 7). Also, this question suggests that changing a button's background is not platform independent.
这个问题的答案可能不是首先使用按钮。所以，我的问题是：是否有一种方法可以在Java中显示一个反映拾取颜色的颜色选择器控件？有点像MS Paint将在填充颜色按钮上显示拾取的颜色。
Maybe the answer to this problem is not to use a button in the first place. So, my question is: is there a method of showing a "color picker" control in Java that reflects the picked color? Kind of like how MS Paint would show the picked color on the "fill with color" button.
