Oh. I see.
What about this?:
if c4d.gui.GetInputState(c4d.BFM_INPUT_KEYBOARD,c4d.BFM_INPUT_CHANNEL,msg) :
if msg[c4d.BFM_INPUT_QUALIFIER] & c4d.QCTRL:

I tried this in at least a dozen of arrangements, but I can't get it to work within the keyboard input (could have something to do with the things Yannick wrote ... maybe). It works by executing a python script without a problem, but in a plugin ... at least I don't know how.
As this works:
def KeyboardInput(self, doc, data, bd, win, msg) :
if msg.GetLong(c4d.BFM_INPUT_CHANNEL) == c4d.KEY_ESC:
self.mode = not self.mode
return True
return False
The most logical thing to me would be to replace c4d.KEY_ESC with c4d.QCTRL, but no chance. Neither does
if msg[c4d.BFM_INPUT_QUALIFIER] == c4d.QCTRL:
the trick.
I get that CTRL, SHIFT and ALT are special keys and maybe there is no way to integrate them like I want it.
I think the whole input stuff is very confusing, and sadly as you mentioned in the other thread the SDK isn't very helpful. As I'm not a regular programmer this is even more difficult I guess.

You're right.
Something is definitely off when it comes to getting the state of the qualifier keys. But only when trying to do it inside of python plugins.
This also looks like it might be intentional.
This is how to get the state of the Ctrl key in C++.
When you press the Ctrl key you get the expected print return
GetInputState(BFM_INPUT_KEYBOARD, BFM_INPUT_CHANNEL, msg);
if(msg.GetLong(BFM_INPUT_QUALIFIER) & QCTRL)
{
GePrint("You pushed the ctrl key");
}
This is the same code. Only written in python.
However..You don't get any return until you have the Ctrl key pressed.. ** then**..some other key pressed at the same time
c4d.gui.GetInputState(c4d.BFM_INPUT_KEYBOARD, c4d.BFM_INPUT_CHANNEL, msg)
if msg.GetLong(c4d.BFM_INPUT_QUALIFIER) & c4d.QCTRL:
print "You pushed the ctrl key"
This looks to me like someone maybe decided that they didn't like the way C++ could get a return from just pressing the Ctrl key by itself. So they intentionally re-wrote the python version so we have to press a second key to get a return from the BFM_INPUT_QUALIFIER's.
We'll need to hear from Yannick or Sebastian about what's going on with these qualifier keys.

It looks as if you don't check the outcome of GetInputState().
At least for me in an Expression Plugin it works getting only the CTRL msg.
So try:
if GetInputState() :
if msg ..etc:
print 'OK'

Hi Lennart.
This doesn't seem to work either. I thought the whole point of these keyboard and mouse functions is that you don't need to use the GetInputState() as msg is already the container with all the input data.

Hi Yannick thank you very much for your effort.
You're absolutely right this simulates exactly the cloning behavior and it's really good to know where to put these queries.
But I'm guessing it is just not possible to get the qualifier key working alone like a normal key (as I need to change the visual feedback before the mousebutton is clicked), as Scott suggested.
Sorry for all the trouble, I guess I will put some kind of gizmo in the viewport and when clicked it will change the mode.
Thanks again

The channel contains the key or button ('A' means A, KEY_F1 means F1)F1, F2, and so on work without problem, a character not so much. I tried c4d.A, not working, I tried it as a string 'A', and I'm running out of ideas
In the case of a key pressed, the channel returned is an integer value containing the ASCII code of the key.
In Python we can call ord()/unichr() to convert a key code from/to its character. Here's some code:
def KeyboardInput(self, doc, data, bd, win, msg) :
channel = msg.GetLong(c4d.BFM_INPUT_CHANNEL)
if channel<128: # ascii key code
chr = str(unichr(channel))
print chr
if chr=='B':
return True
else:
#see KEY_ enum
print channel
return False
Also, only return True if you really used the event. So if you return False the event is passed along and not blocked.

Yes, CTRL and SHIFT qualifiers are not 'normal' keys and are processed in a different way by CINEMA in plugins input events.
Qualifiers are meant to be used in association with other keys.

Could you please offer an explanation why this was changed from the way C++ qualifiers work Yannick?
In C++ we can use the qualifier keys all by themselves without needing to press a second key.
In my own personal opinion...I really like that. And I find it rather annoying that it's not doable within python plugins.
But maybe I'm missing the down side of having it set up this way.
There must be a reason (benefit) why Sebastian decided to deviate from the C++ SDK implementation of the qualifiers. Could you please tell us what that reasoning(benefit?) is for changing it?
Thanks,

I don't see any difference between qualifiers in C++ and Python plugins.
In both C++ and Python we have to press a second key/mouse button to enter KeyboardInput()/MouseInput().
Do you have some code showing this? I have seen the code posted by Scott above but the behavior is the same.

Python plugin version.

We only get a return if another key besides the Ctrl key is pressed
c4d.gui.GetInputState(c4d.BFM_INPUT_KEYBOARD, c4d.BFM_INPUT_CHANNEL, msg)
if msg.GetLong(c4d.BFM_INPUT_QUALIFIER) & c4d.QCTRL:

What makes this whole thing even more strange to me is that if you use this code in a python script or python tag instead of a plugin. The Ctrl key works like the C++ implementation. Meaning..You don't have to hold down a second key to get a result when the Ctrl key is pressed all by itself.
So just in python.
What I'm seeing is that we have two different qualifier behaviors occurring. Depending on whether it's used in a plugin situation. Or in a script or python tag situation. Using the same code.
Is this a bug? Or is it intentional for some reason?
-ScottA
*Edit
Just for sake of full clarity. Here's the python tag code I'm using.
With the timeline running. I get a return from pressing just the Ctrl key by itself.
While in a python plugin scenario. This does not return anything unless a second key is pressed.
This is the same code as the python plugin code. Except of course I have to create the container by hand.
import c4d
def main() :
msg = c4d.BaseContainer()
c4d.gui.GetInputState(c4d.BFM_INPUT_KEYBOARD, c4d.BFM_INPUT_CHANNEL, msg)
if msg.GetLong(c4d.BFM_INPUT_QUALIFIER) & c4d.QCTRL:

I just tested the code in a python tag in the R14 demo. And indeed it doesn't seem to work the same way as in R12&R13.
Maybe that's why we're getting different results?
I still haven't used R14 that much yet. So I'm not very familiar with it. But from what I understand. Maxon changed the Ctrl key options a lot in R14 compared to earlier versions.

Yes your code works.
We're talking about completely different things.
I'm talking about plugins with keyboard or mouse input events == ToolData, ObjectData etc.

I apologize for the confusion guys.
I'm finding out that that the qualifier behaviors change a lot depending upon the specific case they are used in. And not really so much a Python vs. C++ differences kind of thing as I thought.
This is what I've found:
Python Scripts and Both Python & C++ tags:
Only the Ctrl key needs to be pressed to get a return. No second key needed.
Plugins (tool, object,etc..) Both Python & C++
The Ctrl key needs a second key to get a return
Plugins (GeDialog) C++ and Python
When a button or other gizmo is being pressed or activated...Only the Ctrl key needs to be pressed to get a return. No second key needed.
I had no idea the qualifiers behaviors changed so much. Depending on the specific type of script, tag, or plugin they are used in.
Sorry for any confusion I may have caused.
I had no idea they worked like this.
