如何更改jface表的背景选择颜色

In a elipse-rcp application I am setting the background color for a row in a jface table but I don't want the selection to change this color. I want to be able to specify the color change for a selected row.

在elipse-rcp应用程序中,我在jface表中为行设置背景颜色,但我不希望选择更改此颜色。我希望能够指定所选行的颜色更改。

#1

According to this thread, for JFace Viewers (ListViewer, Table, Tree) by means of using EraseItem and MeasureItem events

根据这个帖子,对于JFace Viewers(ListViewer,Table,Tree),通过使用EraseItem和MeasureItem事件

General principle detailed in the article "Custom Drawing Table and Tree Items"

“自定义绘图表和树项”一文中详述的一般原则

SWT.EraseItem: allows a client to custom draw a cell's background and/or selection, and to influence whether the cell's foreground should be drawn

SWT.EraseItem:允许客户端自定义绘制单元格的背景和/或选择,并影响是否应绘制单元格的前景

table.addListener(SWT.EraseItem, new Listener() {
    public void handleEvent(Event event) {
        event.detail &= ~SWT.HOT;
        if ((event.detail & SWT.SELECTED) == 0) return; /// item not selected

        Table table =(Table)event.widget;
        TableItem item =(TableItem)event.item;
        int clientWidth = table.getClientArea().width;

        GC gc = event.gc;               
        Color oldForeground = gc.getForeground();
        Color oldBackground = gc.getBackground();

        gc.setBackground(colorBackground);
        gc.setForeground(colorForeground);              
        gc.fillRectangle(0, event.y, clientWidth, event.height);

        gc.setForeground(oldForeground);
        gc.setBackground(oldBackground);
        event.detail &= ~SWT.SELECTED;
    }
});
