Hot Key Programming
Hi,
Am trying to program a Cntrl+J hotkey in MQL5. The following code does not work, as masking is not supported. Windows function GetAsyncKeyState() also does not work as apparently, MT5 is removing the event. Any suggestions / workaround?
Regards
PR
void OnChartEvent(const int id, // Event ID
const long& lparam, // Parameter of type long event
const double& dparam, // Parameter of type double event
const string& sparam // Parameter of type string events
) {
if (id == CHARTEVENT_KEYDOWN)
if (lparam == (VK_J | VK_CONTROL))
Print("Cntrl + J pressed", lparam);
}
piece of cake
if (id == CHARTEVENT_KEYDOWN) if (lparam == (17)) Print("Cntrl + J pressed"); }
;-)
piece of cake

joking - this is reserver for cross
just choose another key combination and print it out on console

Which cross? Cntrl+J press on a chart gives no action. Plus hardly any other Cntrl+<key> combination is free.

works like a charm...
as for the cross - i was under Wine then, maybe this caused 'cross' display instead of the arrow. I checked my code above under Windows XP - it catches CTRL + J with no problem.
