Well, I wouldn't really call myself a Mac expert OR a QT expert, but I'm at
least familiar with both. I did the initial port of LDView to QT years ago, but
that's now maintained by Peter Bartfai. However, I do get into the QT code
enough to have some familiarity (although it's QT 3.3, not QT 4.x).
Additionally, I've been working on a Cocoa native port of LDView off and on for
a year and a half or so now, so I'm familiar with Cocoa programming. Of course,
that brings up the obvious question of why I would do a Cocoa port when there's
already a QT one. The answer for that is mixed. For one thing, I wanted to
familiarize myself with Cocoa. I was an expert in OpenStep programming back
when there was still such a thing, and since Cocoa is the direct descendant of
OpenStep, that gave me a good grounding. It's amazing what you can forget about
a programming environment after not using it for five years, though, so I'm
currently expert in neither OpenStep programming nor Cocoa programming.
Another reason for the Cocoa port is that QT 3.3 has some issues on the Mac.
These may or may not exist with QT 4, but they're definitely there with QT 3.3.
Also, the Universal LDView binary with a statically linked QT is really large
(15MB?), and I'm not real happy about that. (Windows native binary and Linux QT
binary are both in the 1MB range, with the Linux binary using QT shared
libraries.)
It's also worth noting that the Mac QT version of LDView has some special code
to make it work as well as it does. My help is in HTML form, so there's Mac
code to launch an HTML document in a web browser. The Linux version uses QT's
HTML viewer, but in QT 3.3 at least, that's very basic. Also, the only thing in
my Edit menu is Preferences (which is admittedly very strange). The Mac QT
version is smart enough to move that to the app menu where it belongs, but isn't
smart enough to delete the edit menu, so I have to (carefully) do that by hand.
Macs expect recent files to be in a sub-menu of the file menu ("Open recent"),
so there's custom code for that. Granted, LDView would work with none of these
changes, but it wouldn't be something I would really consider a "good" Mac app.
If you have any specific questions about my experiences, though, feel free to
drop me a line.
