选中时将边框单元格颜色更改为所有 Jtable、JList

Question

I have a little problem with my personal look and fell, I don't want to extend MetalLookAndFeel but I want to create a pure look and feel with BasicLookAndFell.

During the development of the look and feel I realized I had a problem with the label border when a display component like a JTable, JList is selected, I get this effect here on the yellow JLabel.

I wanted to ask you now if there is a constant look and feel to change this color or say how to set the label, do you have any ideas?

thanks for your help, I will post pictures with a small demo below.

Answer 1

Try to set the Table.focusCellHighlightBorder property or with getTableCellRendererComponent similar post for this Swing JTable - Highlight selected cell in a different color from rest of the selected row?

Example how to change the yellow border to red (the selection border)

UIManager.put("Table.focusCellHighlightBorder",
        new BorderUIResource.LineBorderUIResource(Color.red));
