如何通过拖动鼠标禁用缩放而不通过jfreechart中的mousewheellistener禁用？ [英] How to disable zoom by mouse dragged without disabling by mousewheellistener in jfreechart?

问题描述

我想通过鼠标拖动（绘制该矩形）禁用缩放，但不禁用MouseWheel缩放。我在另一个主题中找到了如何在将鼠标向左拖动（restoreAutoBounds）时禁用缩放重置，我对如何解决此问题感兴趣。有没有一点快捷方式呢？

I would like to disable zooming by mouse dragging(which paints that rectangle), but not disable zooming by MouseWheel. I found in another topic how to disable zoom reset while dragging mouse to left (restoreAutoBounds) and I'm interested in how to solve this problem. Is there a little shortcut to do that?

推荐答案

好的，我已经完成了，重写了MouseWheelListener。在chartPannel.setMouseZoomable（false）之后。：

Ok, I've done it, by overriding MouseWheelListener. After chartPannel.setMouseZoomable(false).:

chartPanel.addMouseWheelListener(new MouseWheelListener() {
        public void mouseWheelMoved(MouseWheelEvent arg0) {
            if (arg0.getWheelRotation() > 0) {
                chartPanel.zoomOutDomain(0.5, 0.5);
            } else if (arg0.getWheelRotation() < 0) {
                chartPanel.zoomInDomain(1.5, 1.5);
            }
        }
    });

缩放（输入/输出）域，因为我只想重新缩放域轴。

zoom(In/Out)Domain, because I wanted to rescale only domain axis.
