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);
}
}
