How to set up a frame to draw in for kx plugin

Eddiorov · Apr 13, 2006, 08:58 PM

Hey guys, im planning to do some plugin stuff myself, and after spending hours to get the "sample" working, i now need something in the settings window of my plugin where i can draw several objects to (a graph in this case).
How do i do that?
Info: im using the samle project files and everything, because i wouldnt get a self created working

Are you talking about some static picture, or, are you talking about drawing the graph yourself, from within the C++ code, and if so, do you know how to do that?

if i would know how to do it i wouldnt ask

its about drawing the stuff from C++, the problem is just how to get that frame where i can draw to

The reason I ask, is because you can draw on anything in C++.
You can start with a CWnd object , or you could use another object (i.e. CStatic, CButton), and draw on that.
It is more of a generic programming question then anything kX related.
It is a fairly complicated subject, so I would suggest searching the web for some tutorials on Windows programming with C++, related to drawing in a window (using the Windows API, or MFC).

Additionally, you may want to look up information on subclassing controls, and creating custom controls.

thats the point, how far are those areas integrated into kx, or are there no predefined area functions? such as maybe mysurface = kx_createsurface(x1, y1, x2, x2); or anything?

KX objects are just windows.
When you create the plugin window, you specify its size.
If you create another object to draw on, when you create it, you specify it's size and location, within it's parent window.
Each window has it's own DC (Device Context) for drawing, with it's own properties (size, etc) that defines your drawing surface.
You specify the drawing coordinates yourself, within that DC (the drawing functions take coordinates as the arguments). These coordinates may be relative to the screen size, the client area, the parent window, the DC, etc, depending on what you need to do.
Again, it gets fairly complicated, and all this would be better explained in a tutorial.
It is the same in kX as it would be for anything else.

My I suggest you look at the Dynamics Processor?
That contains a graph of sorts.
I managed to muddle my way through allsorts by just reverse engineering the examples.

Dammit! The new Dynamics Processor (never had a look at it before) seems to be exactly what i planned

Well ok, not really, im planning to do the curve (graph in the middle) with newton's interpolation (dunno coorect name

) providing much more flexibility and saving ressources of the kx chip (the interface calculates a polynom, and just the coefficients are then passed to the chip, making the whole calculation about 10 macs or so

ATM im working with a customized "osciloscope" from the fx pack, just c'n'p into my project and removing the bits i don't need... it semms to work... hardly
