[solved] How to trigger TAxisClickTool by double-clicking
lazarus / 55-TAChart

I use TAxisClickTool with Laz 2.1. When I set its shift state to
"ssLeft" or "ssRight", everything is fine - the user clicks on the
axis and the OnClick event is triggered.

When I now change the shift state to "ssDouble", it doesn't work.
Since the tool has no "OnDoubleClick" event I don't know how to
achieve that when double-clicking on the axis title, the "OnClick"
event is triggered.

In the Shift property, check ssDouble in addition to ssLeft, and it
should work (just tested it myself).

Many thanks. This works, but the ChartEditor demo will then crash
under certain circumstances, see this thread:
