问题描述

我有一个JTable和JTextField,我想突出显示与JTextField中的文本相对应的单元格.我在代码中添加了Todo,但我不知道该怎么做.

I have a JTable and a JTextField, I want to highlight the cell which corresponds to the text in the JTextField. I added Todo in the code but I don't know how to do it.

如何在表格模型中做到这一点?有人可以建议一个代码段吗?

How is it possible to do it within table model? Can anybody suggest a code snippet?

TableModel:

public class ArtikelTableModel extends AbstractTableModel {
private List<Object[]> data;
private String[] headers;
private String wordToBeFind = "";

public ArtikelTableModel(List<Object[]> data, String[] headers) {
    this.data = data;
    this.headers = headers;
}
public List<Object[]> getData() {
    return data;
}

public void setData(List<Object[]> data) {
    this.data = data;
}

public String getWordToBeFind() {
    return wordToBeFind;
}

public void setWordToBeFind(String wordToBeFind) {
    this.wordToBeFind = wordToBeFind;
}



public int getRowCount() {
    return data.size();
}

public int getColumnCount() {
    return headers.length;
}

public Object getValueAt(int rowIndex, int columnIndex) {
    String celValue = (String) data.get(rowIndex)[columnIndex];
    System.out.println(celValue);
    return celValue;
}

@Override
public void fireTableDataChanged() {
    super.fireTableDataChanged();
}

public void findWordInTableAndHighlightIt(String word){
    for(int i = 0; i<data.size();i++){
        for(int j=0;j<headers.length;j++){
            if(word.equals(data.get(i)[j])){
                //Todo: highlight the content of the cell and set the cell border color to red
            }
        }

    }
}
}

自定义渲染

public class ArtikelCellRenderer extends DefaultWebTableCellRenderer{
    protected static  int row;
    protected static int col;
    protected boolean isSelected;
    protected boolean isFocused;
    public Component getTableCellRendererComponent(WebTable tbl, Object v, boolean isSelected, boolean isFocused, int row, int col)
    {
            //Store this info for later use
            this.row = row;
            this.col = col;
            this.isSelected = isSelected;
            this.isFocused = isFocused;

            super.setValue(v); //Set the value as requested

            //Set colors dependant upon if the row is selected or not
            if (!this.isSelected) this.setBackground(new Color((float)0.87, (float)0.91, (float)1.0));
            else this.setBackground(new Color((float)0.75, (float)0.78, (float)0.85));

            //Set a special highlight color if this actual cell is focused
            if (this.isFocused) this.setBackground(new Color((float)0.5, (float)0.80, (float)0.6));

             //Set a special highlight color if this actual cell matches to the JTtextField text
              Todo: ?set background color to green and border color to red

            //and then allow the usual component to be returned
            return super.getTableCellRendererComponent(tbl, v, isSelected, isFocused, row, col);
    }
}
