How to override PLOT to get mouse click?

[ttodua]

I want when user clicks mouse on chart:

1) to alert "Mouse clicked" message
2) to check, if specific KEYBOARD key is also pressed at the same time.

is that possible with override PLOT() ?

(btw, there are ways with custom c# even handler creations, but i wanted to know if there is a simple way with PLOT);

Sorry, I am confused.
You mean the chart or a character on the keyboard?

1) to alert "Mouse clicked" message

This requires a mouse hook. I'll look around for an example.

EDIT:
Actually, it's called a "Mouse Event Handler".

2) to check, if specific KEYBOARD key is also pressed at the same time.

Which key? It makes a difference, for ex, Shift/Ctrl/Alt keys (commonly used in conjunction with mouse clicks) would be different than a normal keyboard character.

I doubt it.
Plot() doesn't have anything to do with the mouse.
Plot() is ultimately an "output" function, not an "input" function.

I went to Version 7 Indicators in Download section, and used the 'Keyword Filter' dropdown to select "Mouse". The indicator "dDrawABC" came up.

I just checked the code, if you understand C# programming this looks to be a great example of what you'll want to do.

The idea is to add an event handler for "MouseDown" to the ChartPanel (basically a reference to your own function that gets called on mouse down events).

Inside your mouse down handler, check for your specific keypress being in down state at same time -- for ex, look at line 369 in dDrawABC.cs for an example using the 'Alt' key.

I think you mean SHIFT ... another typo?

Google for "C# Modifier Keys".
