Jtable cell selection and highlighting

Question

Hi,

I have an attached code, it working but with a little issue. I'm able to highlight a cell with blue color. What I want is after highlighting a single cell with a blue color I want to be able to un-highlight the same cell by clicking it again. For example when I highlight cell 1, it will be highlighted with blue but when I click it again it won't be un-highlighted unless I click another cell then click cell 1 again.

How can I fix this problem.

In the code I'm only testing cell 1 to 4.

Answer 1

U can set condition take one bool value and do something like this

bool isHighlight= false

If (isHighlight)
Set background blue;
isHighlight = true
else
Set background white
isHighlight = false

Answer 2

But here u have tried to add colour on the bases of condition

if (value.equals(oneSValue) || value.equals(twoSValue) || value.equals(threeSValue) || value.equals(fourSValue)) {
            c.setBackground(Color.BLUE);
            c.setForeground(Color.WHITE);
          }
        else {
        c.setBackground(Color.WHITE);
        c.setForeground(Color.BLACK);
        }
       

Answer 3

On mouse click u have to add condition u made a separate function for background colour right
bool isHighlight = false // by default false
Button click function () {

If (isHighlight) {
Call your getTableCellRendererComponent () // set your colour
now set isHighlight to true
}

else {

Call getCellRenderComponent ()
isHighlight is false
}

Answer 4

It won't work because the code uses getTableCellRendererComponent() method
