Hi Miklos,
After digging in some more, I was able to track down the hardware key events to
gtk3gtkframe.cxx in vcl/unx/gtk3. Hopefully this information is useful for
others looking for the same information. Within doKeyCallback function, I set
mnCharCode in the SalKeyEvent object to the value I want and this value is
reflected in the LayoutText function of CommonSalLayout.cxx.
Coming to the actual display, I faced two problems. I was able to display my
glyph by hard coding the value of nGlyphIndex in LayoutText but that results in
every single character in libreoffice printing my glyph (on every menu item,
label, etc.). I need to figure out how to display my glyph based on the value
passed into the LayoutText function based on mapping this value to the value of
the nGlyphIndex. The mapping is the easy part but identifying the control flow
is where things seem to get tricky. Print statements do not seem to help as
they get printed multiple times for a single keystroke (18 times) and I am
unsure which invocation in the loop is the relevant one and an attempt to
insert an if condition based on the value I passed seemed to have no effect.
The other problem I had when I hard coded the value of nGlyphIndex is that the
cursor does not move all the way to the end of the glyph but is in the center
of the glyph so that the next keystroke results in an overlap of the right half
of the glyph with the left half of the next glyph. This is the case only with
the glyph in the font file I generated. Note that I have used my fontfile with
other programs written using Gtk+ and they work fine.
Any ideas would be appreciated.

Hi Arvind,
Try 'git grep key_press vcl/source/', and keep in mind that if you type
into a Writer document, Calc cell or Impress shape, those are all
"custom widgets" in terms of gtk3.

Miklos
