即使在Java中的jTable中禁用行选择后，如何保持当前选中的行突出显示 [英] How to keep the currently selected rows highlighted even after disabling the row selection in jTable in java

问题描述

我在Java中有一个JTable，其中包含5行(可以说)UI.

I have a JTable in java which contains 5 rows(lets say) UI.

我选择2行，并高亮显示这2行，然后单击一个按钮.现在在代码中，在该按钮上，我禁用了行选择，因此单击该按钮后，我将无法再选择其他行.

I select 2 rows and those 2 rows are highlighted and then I click on a button. Now in the code, on that button I am disabling the row selection so that I will not be able to select any more rows once I have clicked that button.

但是问题在于这2行的选择已清除，这意味着在代码中我可以访问这2个选定的行，但是在UI中，禁用后这些行未突出显示.

But the problem is the selection of those 2 rows is getting cleared means that in the code I can access those 2 selected rows but in the UI those rows are not highlighted after disabling.

即使禁用行选择后，有什么方法可以保留UI中的行选择?

Is there any way that I can keep that selection of rows in the UI even after disabling the row selection??

推荐答案

创建一个自定义ListSelectionModel，使您可以切换模型的选择状态.

Create a custom ListSelectionModel that allows you to toggle the selection state of the model.

public class ToggleListSelectionModel extends ListSelectionModel
{
    private boolean selectionEnabled = true;

    public ToggleListSelectionModel()
    {
        super();
    }

    public boolean isSelectionEnabled()
    {
        return selectionEnabled;
    }

    public void setSelectionEnabled(boolean selectionEnabled)
    {
        this.selectionEnabled = selectionEnabled;
    }

    @Override
    public void addSelectionInterval(int index0, int index1) 
    {
        if (selectionEnabled)
            super.addSelectionInterval(index0, index1);
    }

    //  Override other add/remove methods
}

然后在按钮的ActionListener中，可以禁用选择状态.

Then in the ActionListener of your button you can disable the selection state.
