/*
The .uib file format is the binary counterpart of the .ui file
format. It is generated by the ui2uib converter and understood by
TQWidgetFactory; in a future version, it might also be understood
by a uib2ui converter. Experiments show that .uib files are about
2.5 times faster to load and 6 times smaller than .ui files.
The .uib format, unlike the .ui format, is internal to Trolltech
and is not officially documented; it is assumed that anybody who
needs to understand the file format can read the ui2uib and
TQWidgetFactory source code, with some guidance. And here's some
guidance.
A .uib file starts with a 32-bit magic number that allows
TQWidgetFactory to determine the file type. The magic number is
followed by '\n' (0x0a) and '\r' (0x0d), which ensure that the
file wasn't corrupted during transfer between different
platforms. For example, transferring a .ui file from Windows to
Unix using FTP with type ASCII will produce a file with '\r\n\r'
in place of '\n\r'. This is followed by the TQDataStream format
version number used.
The rest of the file is made up of blocks, each of which starts
with a block type (Block_XXX) and a block length. Block_Intro and
Block_Widget are mandatory; the others are optional.
TQWidgetFactory makes certain assumptions about the order of the
blocks; for example, it expects Block_String before any other
block that refers to a string and Block_Images before
Block_Widget. The order generated by ui2uib is one of the orders
that make sense. Just after the last block, a Block_End marker
indicates the end of the file.
The division of .uib files into blocks corresponds grossly to the
division of .ui files in top-level XML elements. Thus,
Block_Widget corresponds to <widget> and Block_Toolbars to
<toolbars>. The internal organization of each block also mimics
the organization of the corresponding XML elements.
These are the major differences, all of which contribute to
making .uib files more compact:
1. The strings are gathered in Block_Strings, a string-table.
When a string is needed later, it is referenced by a 32-bit
index into that table. The UicStringTable class makes the
whole process of inserting and looking up strings very
simple. The advantage of this scheme is that if a string is
used more than once, it is stored only once. Also, the
string-table is preinitialized with very common strings, so
that these need not be stored along with .uib files.
2. TQObjects are referred to by index in a table rather than by
name. The table itself is not stored in the .uib file; it is
rather build dynamically by ui2uib and TQWidgetFactory as new
objects are specified. In ui2uib, the table is represented by
a UibIndexMap object; in TQWidgetFactory, a plain array of
TQObject pointers suffices.
3. The data is packed to take as little place as possible,
without slowing down TQLayoutFactory too much. For example, an
index into the string-table is a 32-bit integer, but in
practice it is rarely above 65534, so only 16 bits are used
for them; when an index above 65534 is met, the index is
saved as 65535 followed by the 32-bit index, for a total of
48 bits.
4. The name of a signal or slot and its signature are saved
separately. That way, if a signal 'foo(const TQString&)' is
connected to a slot 'bar(const TQString&)', the string-table
will only contain 'foo', 'bar', and '(const TQString&)',
instead of the longer 'foo(const TQString&)' and 'bar(const
TQString&)'. The signatures are normalized beforehand to
ensure that trivial spacing problems don't result in multiple
string-table entries.
5. In a signal-to-slot connection, a sender, signal, receiver,
or slot is not repeated if it's the same as for the previous
connection. Bit flags indicate what is repeated and what is
specified.
6. Some of the information stored in a .ui file is useful only
by uic, not to TQLayoutFactory. That information is, for now,
not taken along in the .uib file. Likewise, needless
TQLayoutWidget objects are not taken along.
The arbitrary constants related to the .uib file formats are
defined in uib.h. Constants such as Block_Actions and
Object_SubWidget are given values such as 'A' and 'W' to make
.uib files easier to read in a hexadecimal editor.
The file format isn't designed to be extensible. Any extension
that prevents an older version of TQLayoutWidget of reading the
file correctly must have a different magic number. The plan is to
use UibMagic + 1 for version 2, UibMagic + 2 for version 3, etc.
