Dear Support,

My goal is to create special vertical lines (could be a specialTime Marker as well) on the chart with the following characteristics:

1) When the user hoovers over with the mouse, it is showing a special text, as the tip (or hint). Currently the vertical line`s hint is "Vertical Line". Can I override this?

2) I want to trigger a special action when the user double-clicks on this vertical line (or Time Marker). Currently double-clicking on vertical line activates edit mode of the line, where you change position, width, color, etc. How can I override this again?

How can I do this, if possible at all?
If the vertical line object type is not good choice for such requirements, could you give me some tips about how to achieve what I am looking for?

Thanks.

Shame on me that I haven`t...

Looks promising.
Is this a new page in the wiki? I was browsing the wiki upside-down in the last couple of days to get a grep of chart object, how could I missed it?


Thanks again for the fast support!

It is there already for more than a year .

A follow up question on this:
When I double-click on a line, the method selected() is called. This is fine, however I want to avoid that the chart object is changed into an `edit` mode (top, middle, bottom there is a circle; and the cursor changes to a + sign). Is there a way to avoid this visual change of the line?

No it is not possible. Only uneditable chart objects don't have edit control points (see IChartObject.setLocked). But you can't select uneditable chart objects (i.e. the select event won't fire when you double-click such object), you can only catch the highlighted event for such objects.

After some testing it seems that I could achieve with a workaround to not to make visible changes on the chart object when the user selects it.
And this workaround would be if I fire a mouse click, or hit enter.
Whenever a chart object is in an edit mode, if I click somewhere else on the chart, or hit Enter, the edit mode closes.

How could I fire an Enter key (or a mouse click) in the selected() event?

I quickly came up with this:

    public void selected(ChartObjectEvent e) {
        ....
        try {
            Robot robot = new Robot();
            robot.keyPress(KeyEvent.VK_ENTER);
            robot.keyRelease(KeyEvent.VK_SHIFT);
            robot.mousePress(InputEvent.BUTTON1_MASK);
            robot.mouseRelease(InputEvent.BUTTON1_MASK);
        } catch (AWTException ex) {
            ex.printStackTrace();
        }
    }

Enter closes the edit mode. The mouse click resets the mouse pointer (from the + sign, which is the edit mode's mouse pointer).

Any drawbacks of this?
