This was a mistake, of course. Nested event loops don't need (or want)
independent server connections.
We initialize the connection early in GEventLoop for e.g. users that
want to get the size of a GDesktop before the connection has been
established.
Bug noticed by Andreas, introduced by me ;-)
As a consequence, move to use an explicit handshake() method rather than
calling virtuals from the constructor. This seemed to not bother
AClientConnection, but LibGUI crashes (rightfully) because of it.
Currently the two available input types are:
- GMessageBox::InputType::OK (default)
- GMessageBox::InputType::OKCancel
Based on your choice, GMessageBox::exec() will return ExecOK or ExecCancel.
Currently this will be used by the WindowServer to show some dialogs.
This is needed since WindowServer can't use LibGUI and reimplementing
message box functionality inside WindowServer would be silly. :^)
The only dialog supported in this initial version is --shutdown
This is the same as calling FileSystemPath(foo).string(). The majority of
clients only care about canonicalizing a path, so let's have an easy way
to express that.
In order to repaint the GUI after the sound thread has produced some sweet
new waves, we post a CCustomEvent to the main thread's event loop and then
wake up that event loop via CEventLoop::wake().
* Add a LibAudio, and move WAV file parsing there (via AWavFile and AWavLoader)
* Add CLocalSocket, and CSocket::connect() variant for local address types.
We make some small use of this in WindowServer (as that's where we
modelled it from), but don't get too invasive as this PR is already
quite large, and the WS I/O is a bit carefully done
* Add an AClientConnection which will eventually be used to talk to
AudioServer (and make use of it in Piano, though right now it really
doesn't do anything except connect, using our new CLocalSocket...)
This frees up the main thread to draw the GUI. The secondary thread uses
a pipe to trick the main thread's event loop to break out of select() and
update() the PianoWidget. :^)
The idea here is to implement a simple synhesizer that allows you to play
music with your keyboard. :^)
It's a huge hack currently but we can improve upon this.
Here goes the first attempt at using VisualBuilder to make an application.
There are many features missing that we are gonna have to implement,
noticeably custom widgets (for the glyph editor and glyph map widgets)
but this patch already moves most of the UI layout to a form file. :^)
Instead of manually doing String::format("%d"/"%u") everywhere, let's have
a String API for this. It's just a wrapper around format() for now, but it
could be made more efficient in the future.
