Question

I am working on a big Gui project. Lots off complex stuff has been done and I cannot change the structure of the code. And as it is a complex project it is difficult to explain or give an SSE but I will try my best.

In our project some people have implemented their own Table. All the cells int the table are a class called CellPanel which extends JPanel class. So all table cells are JPanels actually. And these crazy guys have implemented their own mouseClicked function which is about 400 lines. So I am not pasting it here for the good of everyone 🙂 But that mouseClicked method only works if it is a right click. SO I have the chance of doing something like this:

public void mouseClicked(MouseEvent e) {

    DropTable.selectedColorMng(rowInTable);
    if(e.getButton()==MouseEvent.BUTTON1) {
        System.out.println("left click");
    }
    else{ 
        // 400 lines of code here
    }
}

Now what I want to do is that these CellPanels are designed to contain a label and an icon. It has always been used like this. No dynamic content inside. But now we have a requirement and I have modified these CellPanels to contain JList in a ScrollPane. But these JLists are not clickable. I want to scroll them make multiple selections, but they do not respond to my left clicks. So I think I have to fill inside the if statement of the above code.

But how?

Answer 1

I’m not sure if I understood your question completely. I understood, that your CellPanel catches the click events so that they doesn’t reach the JList which is contained in the CellPanel.

If it is like that you can simply delegate that event in the mouseClick of the CellPanel to the JList there must be a reference to it as it is shown in there.
