- Move over the last of the original settings dialog code to QT. It was
actually a bit easier to write in the QT version. wxWidgets was
definitely not ideal for that because the pages would fully
create/destroy every time.
- [Win32] Fix os_dlopen so that it only appends .dll if not present
- [MacOS] Fix name dialog text edit widget issue (it would be better if
we could just use the list widget for editing labels, will have to
look in to that in the future)
- Tweak the settings UI a bit more and make 30 FPS default
- Add a macro to convert a QString to a UTF-8 const char * string
- Rename build/plugins to build/obs-plugins
- Remove the last of the wxWidgets code
- Fix the size issue with list boxes on mac. Was displaying the list
boxes with an improper size. Turns out it was just the wrong size
policies on the frame below.
- Ensure the main windows are fully displayed *before* initializing
subsystems. This ensures that the graphics system will properly start
up on macos, and allows the glitch fix.
- Made a workaround for weird QT glitch that would happen to the parent
of a pure native widget that also has internal painting fully
disabled. (Should definitely write an example and report this bug on
the QT forums)
- Had the wrong names set for the up/down widgets for sources/scenes
- Updated the settings dialog and gave most of the widgets actual object
names
- Added code for the settings window. Settings window should now at
least display.
- I seem to have fixed ths issues with the main preview widget. It
seems you just need to set the right window attributes to stop it from
breaking. Though when opengl is enabled, there appears to be a weird
background glitch in the Qt stuff -- I'm not entirely sure what's
going on. Bug in Qt?
Also fixed the layout issues, and the widget now properly resizes and
centers in to its parent widget.
- Prevent the render loop from accessing data if the data isn't valid.
Because obs->data is freed before the graphics stuff, it can cause
the graphics to keep trying to query the obs->data.displays_mutex
after it had already been destroyed.

Notes and details
--------------------------------------------------
Why was this done? Because wxWidgets was just lacking in many areas. I
know wxWidgets is designed to be used with native controls, and that's
great, but wxWidgets just is not a feature-complete toolkit for
multiplatform applications. It lacks in dialog editors, its code is
archaic and outdated, and I just feel frustrated every time I try to do
things with it.
Qt on the other hand.. I had to actually try Qt to realize how much
better it was as a toolkit. They've got everything from dialog editors,
to an IDE, a debugger, build tools, just everything, and it's all
top-notch and highly maintained. The focus of the toolkit is
application development, and they spend their time trying to help
people do exactly that: make programs. Great support, great tools,
and because of that, great toolkit. I just didn't want to alienate any
developers by being stubborn about native widgets.
There *are* some things that are rather lackluster about it and design
choices I disagree with though. For example, I realize that to have an
easy to use toolkit you have to have some level of code generation.
However, in my personal and humble opinion, moc just feels like a
terrible way to approach the problem. Even now I feel like there are a
variety of ways you could handle code generation and automatic
management of things like that. I don't like the idea of circumventing
the language itself like that. It feels like one giant massive hack.
--------------------------------------------------
Things that aren't working properly:
--------------------------------------------------
- Settings dialog is not implemented. The dialog is complete but the
code to handle the dialog hasn't been constructed yet.
- There is a problem with using Qt widgets as a device target on
windows, with at least OpenGL: if I have the preview widget
automatically resize itself, it seems to cause some sort of video
card failure that I don't understand.
- Because of the above, resizing the preview widget has been disabled
until I can figure out what's going on, so it's currently only a
32x32 area.
- Direct3D doesn't seem to render correctly either, seems that the
viewport is messed up or something. I'm sort of confused about
what's going on with it.
- The new main window seems to be triggering more race conditions than
the wxWidgets main window dialog did. I'm not entirely sure what's
going on here, but this may just be existing race conditions within
libobs itself that I just never spotted before (even though I tend to
be very thorough with race conditions any time I use variables
cross-thread)
