Hi all!
Last time I asked how to catch keyboard input. Mirek directed me to the (simple) answer. Thanks!
But now I want to do the other way: I want to simulate keyboard input.
Is it possible to "send" a key via code?
The second question is: Is it possible to popup a static rect with some buttons - but without to get focus?
I need to develop a virtual keyboard for a touchscreen solution - therefore I dont want to loose focus on selected editfield while typing (=clicking) on the popped up keypanel.
Is that possible?
I hope, I didn't explain too confusing 
Thanks in advance,
WebChaot.

Just call Key method by your code (normally, it is called as result of Key event, but nothing can prevent your code doing so).

There is "NoWantFocus" flag - Ctrls with such flag cannot obtain focus by "standard" means (e.g. by TopWindow). They still can get it explicitly by your code, but that you can avoid..

I see. Yes, it is OK. However, maybe even moving focus would be OK - virtual keyboard is mouse thing, I would just left focus processing as it is and simply send virtual keyboard events to GetFocusCtrl()->Key
I hope, I didn't explain too confusing :)
Actually, very understandable
More actually, that app sounds interesting. Keep us informed

>>> I see. Yes, it is OK. However, maybe even moving focus would be OK - virtual keyboard is mouse thing, I would just left focus processing as it is and simply send virtual keyboard events to GetFocusCtrl()->Key
I have to play around tomorrow. I want to let the edit cursor (does it have a name - the line which is blinking) stay visible. Therefore I thought, that the editfield should be focused all the time.

Sure! As I wrote you some weeks ago, we are new in Ultimate++ and we decide to develop all our new applications with it. So now we started with our new version of a touchscreen application. We will send you more information and some screenshots, when there is something interesting to show. At the time we do some base development (touchscreen elements, advanced array control and much more).
Do you like to get technical feedback? Because we try to let U++ source as it is and only to create and / or overwrite our own classes (to be able to update U++ development releases without much work). But in some cases (3 times I think) we had to change U++ sources (very small changes!). Maybe it is possible to include this changes in next releases, because they are useful for others too?
Thanks,
WebChaot

Well, the terminology names that blinking thing a "caret". Anyway, that is exactly the reason to keep normal focus processing and make your virtual keyboard "NoWantFocus". (Now thinking about it, maybe that is exactly what you wanted to do

Of course! Actually, U++ develops fast, I hope you do not want to patch each single version
Of course, the reasons for patches have to be stated (and sometimes discussed).
