Thomas- unfortunately, this is the reality of cross platform
development in Revolution.
IMHO Ken's answers paint the ideal scenario (use the default control
settings, use the Preview/ Look and Feel menu item). In practice for
me, that doesn't work.
Yes, the core engine is remarkably cross-platform. But the IDE really
falls short of previewing what your app will look like a) when built as
a standalone and b) when run on other platforms, and combinations of a)
As far as I can tell, Rev has not improved at all in this respect.
Someone correct me if I'm not being sensitive enough, but *has* this
improved at all from 1.1.1 through 2.1.1RC?
There are all kinds of hacks and workarounds, but you can pretty much
count on spending a lot of tweaking various platforms to get it right.
Examples of what I'm talking about:
-- View | Look and Feel menu will show you the new shapes for the
controls, but it *will* get the colors and fonts wrong.
-- Distribution Builder messes up colors (see thread "Re: DBuilder-
sets "bottomColor" to 0,0,0?")
-- Standalones may get a different background color, or other color
properties from the OS when running as a standalone. Dirty workaround-
look up colors in the Windows Registry when your app launches.
-- Properties inheritance is difficult to use. (you are a smart guy,
and graphics guru, but your attempt to use properties inheritance in
groups etc was less than spectacular eh?)
I want View | Look and Feel to show me *exactly* what it will look like
on another platform. Of course fonts and gamma will not be the same. Of
course Windows and Linux cannot preview Mac OS appearance manager. But
other than that- WHY should the View | Look and Feel results look SO
different than at runtime? This is after all, a 4GL with an
emulated-abstracted display system emulated-abstract GUI widgets,
right? It always looks different, and there are always surprises.
By gut feeling is that the Rev IDE does not isolate it's display
properties from the user's stacks, well enough. The IDE colors/biases a
lot of your projects display properties to be the IDE's instead of what
at runtime will be gotten by your stack from the engine and OS.
Sorry for all this, I've just spent a couple of hours trying to figure
out why the bottomColor and shadowColor are getting so screwed up in my
standalones- why it differs between stacks and substacks in the
standalone, and wondering if the Distribution Builder is an AI or
something which would explain the erratic results.
Zipping mouth now...
