actually no. this is where users and many toolkits and apps get it totally
wrong. so you specify font size. what about icons and other elements then?
that is precisely why efl just uses a "scale" factor. a single number (1.0
being the default, 2.0 == 2x as big etc.) where everything that can scale
is multiplied by that value, and that value is farmed out to the user to
decide what works best for them. enlightenment has an option to calculate
the scale factor based on dpi (with a base dpi of X == 1.0) using the
real physical dpi to do it. this is one of the first questions
enlightenment asks in its wizard giving you a whole bunch of options to
choose from with previews so you pick what looks right. but this only
affects efl/e.
another way users/toolkits do this is "set dpi". you DO NOT SET dpi. dpi
is a property o the screen (and its current resolution). SETTING it to get
something to scale up is NOT right. now, if you do, apps that want to
actually display something at a specific physical size on the screen
(15x33mm for example) can't because dpi is now wrong. dpi is directly
related to screen size, and querying screen size is now no longer a way to
figure out what kind of screen you might have (~32"+ tv? desktop
(~19-30")?, laptop (~10-17"), tablet (~7-10")? phone(~3-7") etc. (yes.
things play guessorama based on these kinds of things to alter behaviour
to fit that kind of device, but if you fake dpi then these guesses are
going to be wrong).
I fully agree and I illustrate it : my laptop is 14'' and 1920x1080, and
I have a second screen 24'' and 1920x1080 !!
So "scale" factor is a good solution. But...
It does not work : the scale factor should be different for each screen.
There is a "Scale" factor in the "Screen Setup" but it has no effect
(in last git version).
What do I miss ?
actually... this is possible. :) with efl+enlightenment it is. e will send
messages to the window to change scale factor *IF* you set up the screen
with a different scale factor in the screen setup dialog... the problem is
this messes up enlightenment right now as scale factor is "per process" as
opposed to "per parent object" (well actually it is per parent object but
the way it's implemented is problematic for e as it has a single window
spanning both screens...). check the screen setup dialog under "use
profile". check it then you can even select a whole different config
profile for apps on that screen AND optionally a custom scale
factor... :) ... now drag window from screen to screen.. :)
but this seems to have broken in current git though... it DID work when i
wrote this support...
np, I wait and buy a magnifying glass...
fixed it. bug added to e that forced ELM_PROFILE to be set that override the
runtime on the fly messages
Thank you. Sorry: I had no time enough to buy the magnifying glass...
