- two modes (unfortunately)
- MOVE mode is obvious (arrows and zooms moves cursor, SET leaves MOVE and goes to WRITE)
- in WRITE mode we could have:
* arrows for typing
* FUNC to use another letter from the same arrow / go to MOVE (as in EDI)
* MENU to cancel
* zooms for space/backspace
* shoot_full / DISP for OK
* shoot_half changes chars
In my experience too easy make shoot_full instead of shoot_half. No nuclear rocket starts, but probably I need reenter something from start again and again something just because I need different character set in the string.

I like how it works right now: DISP (MENU) switch between three modes. If make obvious which one is active, then no problem with it. Switching between modes is relatively rare event and this surely prevent any unexpected finalization. Just like MBOX - we can't say ok/cancel with "hotkey". Only select and "Enter".

Special characters should contain a space (for cameras without zoom).

And I have no idea how to implement backspace...
shoot_half in MOVE mode. not very comfortable, but relatively obvious.
Anyway most of cameras are unaffected. Just few of them (6 + probably 2 with touch screen) have no zoom. For camera with touch volunteer owner could write own cool touch keyboard. :)

Ok, you're right. But at the moment I don't know how to use these buttons below the text... How can I select them? I mean "OK" and "CANCEL"

I have now read all your post and think there should be two modes (as tvstar says). One for typing and one for the buttons.

My idea is to use the keys so:
arrows + ok = typing
MENU = change mode (typing / buttons)
zoom (or jogdial)  = text navigation
disp = space
shoot_half = change chars

For backspace erase or video button if present. But I don't know if there are cameras that haven't one of them and whether there are other buttons.

I'm sure that tsvstar said about three modes;) It was also said, that only few cameras have ERASE button unfortunately...

After reading all these proposals I have some idea.

Ok, give me one or two days and I prepare a little bit rewritten code and we will discuss concrete solution;)

Oh yes tvstar writes about three modes.  :)
Then we can use zoom as in my first Idea:
Quote from: TobiMarg on 02 / January / 2012, 12:19:18
  • To delete a character zoom out.
  • To insert a space zoom in.
and move in text/move mode with the arrow keys.

If yours is a better idea please write it and we'll wait.

I just like to change some things in your code and merge all these things together... :)

Ok, I'll wait. (or make a few improvements on my own  :))
But do you know how to fix that:
Quote from: tsvstar on 04 / January / 2012, 06:28:26
2. Current version is wrongly fill up on init string. Often strange symbols are exists.
If yes, please fix it and say what the problem was.

I have no idea, what's the problem. But I can't see, wheter c array is somewhere filled with zeros? Maybe this array is not zeroed at start and just contain random bits from memory?

About my changes - I like to for example replace tbox_chars with three-dimensional array, just like it is done in EDI. This way we don't need to place separators into this variable and use it in simpler way.

Code: [Select]
{
  {"a", "b", "c","d", "e"},{"f", "g", "h","i", "j"},{"k", "l", "m"...}...,
  {"A", "B", "C","D", "E"},{"F", "G", "H","I", "J"},{"K", "L", "M"...}...,
  {"1", "2", "3"},{"4", "5", "6"},{"7", "8", "9"...}...
}

One of my ideas is also to change a little bit draw statement. I hope I'll not get lost;)

Ok, I have a little bit changed the pattern. It was to little time to work on typing stuff, but I hope TobiMarg code could be introduced here with only minor changes. Some things with new letters array have to be changed. Of course, if you like this idea ;)

Other change is to add conditional drawing of the keyboard/buttons/something below the text field. Buttons are useless outside the 'B' as well as keyboard is useless in 'M' and 'B'. So only one of these things should be visible at the time.

I made this pattern and I would try to do something more, but it is 1:25 am o'clock here and I very like to go sleep...

0, // flag

};


I also just tried to make code more understandable. I think, that the size of the tbox (I mean whole window) can be fixed, it might a little bit simplify the code.

Tobi - I would like to ask you to write your magic stuff that writes the msg in the window, since I don't understand this code correctly ;) I'll try to provide general idea of usage of buttons with the new array.

PS. Many thanks to all of you!

outslider,
Previous version is better. In new version keymap is hardcoded and couldn't be replaced.
In EDI no problem what is internal organization of keymap, because it is script and easily could be edited at any moment.

What is benefit of previous version and why TobiMarg (?) make this in this way. Because it was my request.
It easy to load such version from regular text file, which could be choosed or edited.
I could prefer different special symbols, I could add more sets to file (for example national characterset).

It will be module interface task to prepare this thing, because I plan to include into this keymap also module name (to give possibility to user change not only keymap but even input method).

Now keyboard lost big piece of its flexbility.
