UI degree symbol   
I'm in need of expressing a temperature for which I need to display a degree symbol. I cannot figure out an option to 
display the degrees. Is there any key combination or some option by which I can introduce degree symbol in the text?

Any suggestion on this is welcome.

Re: UI degree symbol   
Hi,

to enter a degree-symbol in Photon, use the compose sequence
   Alt 0 ^
(press and release each of these keys one after the other, not all at once.)

A number of special symbols can be generated from the keyboard using these compose sequences; the sequences always start
 with hitting the 'Alt' key.

For a list of available compose sequences, see in the docs:
  QNX Photon micro GUI 
    / Programmer's Guide
      / Unicode Multilingual Support,
  the paragraph "Photon Compose Sequences".

You can also look at the file 
  /usr/photon/keyboard/compose.inc
that contains all compose sequence definitions.

Regards,
- Thomas

Re: UI degree symbol   
Hi Thomas,

I tried the following key combinations in Photon App builder as follows.
          Created a new project.
          Placed a button in the base window.
          Tried to edit the button text as mentioned ("Alt 0 ^").
          But I am not getting the symbol.
          The font of the button is TextFont 9	
          Any other possible ways?

The mentioned docs were also asking us to use the same key combinations. (Alt 0 ^)

Any suggestions?

Regards,
Lakshminarayanan.R

Re: UI degree symbol   
Hi,

no, no other suggestion - but for me, it works - even under Windows. 

Two things are important to note:
 - the keys must be pressed and released individually, i.e.,
   press Alt, release Alt, press 0, release 0, ...

- Since the caret ('^') can be combined with other characters to form 
  special symbols (like, e.g., â), it doesn't generate its symbol right away - 
  you need to press the '^' key followed by the Space key to actually 
  generate the required symbol.

So for the degree symbol, you'll need to hit
   Alt
   0
   ^
   Space

Hope this helps...

RE: UI degree symbol   
Though elementary, that was a lucid explanation and it solved the problem. Thanks Thomas.

Re: RE: UI degree symbol   
I want to generate a subscript say, for H20, for example. I went through the unicode multilingual documentation but it 
doesn't mention anything about the subscript although it mentions about the superscript.

Please apprise me if generating a subscript is possible in photon.

Re: RE: UI degree symbol   
PtLabel or Pt*Text do not support it by default. You can use a set of labels with different font sizes, or you can use 
PfRender() to render text yourself.
