Stocks software, mouse_over

Hello,

I'm wondering how developpers dealing with Stocks
software, manage to allow user to visualize 'stock datas'
when moving mouse over a 'barchart' or a 'average
line' ???

Is it possible to achieve this in C# ?
If so, what's the 'secret' behind ? (detection
collision ???)

I'm eager to understand !

Hi Philippe,

It really depends on which control is used to display bar charts. I think
some controls allow for specifying hint text for every bar on the chart, and
the text will than be displayed when the mouse pointer is over the bar.

Even if you draw bar charts with plain GDI+, you can employ the ToolTip
common control (requires P/Invoke calls to API level functions in this
context) to display stock information tips. You should be also easily able
to detect the "mouse over" event, as far as I remember it's one of the
standard events exposed by the Control class.
 
Thank you for replying Dmitriy,

Your idea of GDI+ and tooltip sounds nice...

Would you kindly give me a quick code example.

Thank you so much -)))
