问题 I want to change color of whole row in my JTable. I defined the JTable: JTable table = new JTable(data, columnNames); where data, columnNames are the String tables. The most common way to do this is to write own class: public class StatusColumnCellRenderer extends DefaultTableCellRenderer { @Override public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int col) { //Cells are by default rendered as a JLabel. JLabel l =

问题 I have a JTable and one of its columns should display an image; I overrided getTableCellRendererComponent method of DefaultTableCellRenderer to do this. But the problem is while the image is not Null & cell is displaying it this method is called over & over (like it is called in an infinite loop) and uses 100% of CPU! (When the image is Null there is no problem!). What is the problem? My extended class is: public class imageCellRenderer extends DefaultTableCellRenderer{ @Override public void

问题 I'm working on an app using the Nimbus Look and Feel. There's a table and one column contains buttons (using the Table Button Column from Rob Camick). That does work, but the result isn't what I had expected. I have tried to fix the look, but to no avail. So the question is: how do I change the "background" (the area outside the rounded rectangle) of a Nimbus button? Preferably in a non-hacky way :-) Using the default Table Column Button, the result looks like this: As you can see, the

问题 Can someone give me an example of how to get the background color of a particular cell in a JTable? I am unable to find an example of how to do this. Plenty of examples on getting the value in a cell, but not the background color of a cell. 回答1: It should be something like the following (fixed according to all comments): Important: use table.prepareRenderer(...) to let JTable do all work for you public Color getTableCellBackground(JTable table, int row, int col) { TableCellRenderer renderer =

问题 I use Netbeans to develop a java application, I have a result set from MYSQL database and i want to put this data in a JTable. I have a problem when I want to change background color of a JTable cell based on its value (ex: if the value of a cell in Jtable isn't equal to 1, its color must be red).

问题 Basically I have a JTable , and this JTabel will have a product in one cell, and then in the cell directly below it the cost. The product name should be aligned to the left. The product cost should be aligned to the right. I don't actually care what the alignment of other cells in each row is. So I need to set the alignment of either individual cells, or individual rows.
