Hi,
One way to do this is to assign a callback function to the panel. You
can then check for key presses. The eventData1 parameter will contain
the extended key code. If the callback function is called
'ProcessPanel', then the code would look something like this:
int CVICALLBACK ProcessPanel (int panel, int event, void *callbackData, int eventData1, int eventData2)
{
switch (event)
{
...
case EVENT_KEYPRESS:
switch (eventData1) // (will contain the key
code)
{
case
VAL_ESC_VKEY: // close the window
HidePanel (panel);
break;
// ... optional
checks for other keys such as arrow keys, <home>, <end>,
etc.
default:
break;
}
break;
}
return 0;
}
Alternatively, you could simply assign ESC as the hotkey to a button on
the panel and assign a callback to this button to hide the panel. If
you didn't want it displayed, you could overlay an opaque canvas over
this button to hide it and prevent a user from clicking on it.
