Separating Click from Shift-Click ?

[Guillaume Dargaud]

I'm trying to separate click events (both left and right) from shift-click, ctrl-click and
shift-ctrl-click. This for a graph that has zooming enabled.
When I'm in the callback function in VAL_LEFT_CLICK, how can I know if shift or Ctrl is pressed ?
I looked at the various keyboard functions and code samples but they all seem to assume that
another key is pressed (they respond to EVENT_KEYPRESS events). The callback data doesn't contain
info on keys...

Look at the sample project ..\samples\userint\moustate.prj that ships with CVI. It calls GetGlobalMouseState (defined in userint.h) in a timer callback to check VAL_SHIFT_MODIFIER (shift) and VAL_MENUKEY_MODIFIER (Control), but you could call it on a CLICK event.

Thanks.
I thought I'd searched all the functions with mouse in their name... Not so !


BTW: I'm just trying out CVI 7.0: why does the source code browser window disappear each time I
double click on some of its content ? It's annoying.
