JTable刷新 [英] JTable refreshing

问题描述

我将JTable与水平和垂直滚动条一起使用.我的JTable在包含数据的行之后有空白空间. 当我打开位于我的桌子下方的面板时，它会隐藏JTable的一部分，并在JTable上显示滚动.这是正常现象，但是我关闭该面板后，没有数据的空白区域变为灰色而不是白色. 仅当我的JTable上具有水平滚动条时，才会发生这种情况.我想我必须强制JTable重新绘制，我在TableHeader和JTable上尝试了resizeAndRepaint()，但是没有用.

I use JTable with horizontal and vertical scrollbars. My JTable has empty space after rows with data. When I open panel that is situated down of my table it hides a part of JTable and scrolling appears on JTable. This is normal behavior, but then I close that panel, empty space without data becomes grey instead of white color. This only happens when I have horizontal scrollbar on my JTable. I suppose I must force JTable to repaint, I tried resizeAndRepaint() on TableHeader and JTable but it didn't work.

请帮助！谢谢！ 如果对表执行了任何调整大小操作，则在这里调用resize()代码

Please help! Thanks! Here is resize() code invoked if any resize action was performed on table

for (int i = 0; i < columsNum; i++){
        TableColumn column = this.getColumnModel().getColumn(i);
        int preferedSize = //current size
        int minimumSize = // min size
        if (minimumSize != ColumnSizeCalculator.UNDEFINED_WIDTH)
            column.setMinWidth(minimumSize);            
        column.setPreferredWidth(preferedSize);        
    }   

    this.revalidate();
    this.repaint();

推荐答案

默认情况下，JTable不会在垂直方向上填充滚动窗格的视口.尝试致电

By default, a JTable does not fill the viewport of a scrollpane in the vertical direction. Try to call

table.setFillsViewportHeight(true);

在您的桌子上，然后重新粉刷桌子应该可以.

on your table, then repainting the table should work.
