JTable中的图像的HTML问题 [英] html issues with images in JTable
问题描述
在我的TableModel中，在其中一行中，我返回了如下所示的html代码：
$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ {$
case 0：
String sTest =< div style = \margin-left：100px; \>< img src ='+ new ImageIcon（Wds.class.getResource （/resources/video.png\")++'< / div>;
返回< html> + sTest + sTest +hello+< / html>;
默认值：
throw new IndexOutOfBoundsException（）;
$ b $ p
$ b现在的问题是HTML支持Java似乎很糟糕。
我需要使用margin-left，margin-top等来控制图片。问题是如果我使用< div样式>它会导致换行，所以之后的所有内容都会在下面一行。如果使用< span style>，则不会导致换行符，但页边距不能与< span style> ;（它应该）;
我也尝试创建自定义的TableCellRenderer并在其中添加.css值并使用< div class>但换行问题仍然存在。 in < div style>消除换行和 margin-left 通常和< span style>一起工作，但是看起来Java对HTML的支持相当差。
以下是完整的SSCCE代码：

class MyTableModel extends AbstractTableModel {
private String [] columnNames = {Column1};
public void addElement（String sElement，String sElement2）{
list.put（sElement，sElement2）;
fireTableRowsInserted（list.size（），list.size（））;
$ b @Override
public int getColumnCount（）{
return columnNames.length;
@Override
public int getRowCount（）{
return list.size（）;
}
@Override
public String getColumnName（int col）{
return columnNames [col];
$ b @Override
public Object getValueAt（int rowIndex，int columnIndex）{
switch（columnIndex）{
case 1：
String sTest =< div style = \margin-left：100px; \>< img src ='+ new ImageIcon（Wds.class.getResource（/ resources / video。 png））+'< / div>;
返回< html> + sTest + sTest +hello+< / html>;
默认值：
throw new IndexOutOfBoundsException（）;

I have extendeded AbstractTableModel to create a custom TableModel. The reason for doing this is to bind a hashmap to a JTable.
Within my TableModel, on one of the rows I am returning html code like this:
@Override
public Object getValueAt(int rowIndex, int columnIndex) {
switch (columnIndex) {
case 0:
String sTest = "<div style=\"margin-left:100px;\"><img src='" + new ImageIcon(Wds.class.getResource("/resources/video.png"))+ "'</div>";
return "<html>" + sTest + sTest + "hello" + "</html>";
default:
throw new IndexOutOfBoundsException();
}
}
The problem I have now is that the html support in Java seems to be pretty bad.
I need to control the images using "margin-left, margin-top" etc. The issue is that if I use "<div style>" it will lead to a linebreak, so everything afterwards will be one row below. If I use "<span style>" it doesn't lead to a linebreak, but margin doesn't work with "<span style>" (which it should);
I have also tried creating custom TableCellRenderer and add the .css values there and using "<div class>" but the issue with the linebreak remains.
Usually "display:inline" in "<div style>" eliminates the line-break and margin-left usually works with "<span style>", but it seems Java has pretty poor HTML support.
Does anybody have any suggestions on how I can solve this?
Here is full SSCCE code:
private Map<String, String> list = new LinkedHashMap<String,String>();
class MyTableModel extends AbstractTableModel {
private String[] columnNames = {"Column1"};
public void addElement(String sElement, String sElement2) {
list.put(sElement, sElement2);
fireTableRowsInserted(list.size(), list.size());
}
@Override
public int getColumnCount() {
return columnNames.length;
}
@Override
public int getRowCount() {
return list.size();
}
@Override
public String getColumnName(int col) {
return columnNames[col];
}
@Override
public Object getValueAt(int rowIndex, int columnIndex) {
switch (columnIndex) {
case 1:
String sTest = "<div style=\"margin-left:100px;\"><img src='" + new ImageIcon(Wds.class.getResource("/resources/video.png"))+ "'</div>";
return "<html>" + sTest + sTest + "hello" + "</html>";
default:
throw new IndexOutOfBoundsException();
}
}
}
You should handle the alignment in a custom TableCellRenderer, for example. The example shows a ListCellRenderer, but the principle is the same.
Addendum: I need to add several icons and position them differently within the cell.
Your implementation of TableCellRenderer can return any desired Component—even a JPanel with its own layout, such as the StatusPanel shown here. You may also need a custom TableCellEditor.
