Implement WatchModel::data() to return the right values
for Qt::EditRole, obsoleting the role matching in the delegate.
Similarly, handle Qt::EditRole in setData(), leaving only
'Change watch expression' in the delegate, which removes
and recreates a row, causing crashes when done in setData().
assignValueInDebugger: Pass on WatchData as well, pass
on values as QVariant. Based on that, do more extensive
checks in CDB, preventing assignment of non-PODs.
Locals/Watch editing:
* Disable while running
* Edit pointer values as hex with validation.
CDB: Strip class types off reported pointer values and reformat
the values as short 0x-pointer values, introduce flag to
WatchData::source to do dumper expansion handling.
Windows: recognize int64 as int.
Register handler: Fix accessing uninitialized value.
Create delegate widgets with validation for bool/int/float
types, using a QVariant-type modelData property.
Also fix register editing to be validated for quint64 values
and editing longer values as hex bigints. Anything else is not
editable.
Use a quint64 as address. Split apart special handling of
QAbstractItemModels of old shared-library based dumpers
(passing '$'+ special expression as address) into separate
dumperFlags QByteArray.
This replaces the (de facto) singleton engines and data handlers by classes
that are instantiated per run. The DebuggerRunControl will now create an
object of (a class derived from) DebuggerEngine that contains all the relevant
"dynamic" data.
DebuggerManager is no more. The "singleton" bits are merged into DebuggerPlugin,
whereas the data bits went to DebuggerEngine.
There is no formal notion of a "current" DebuggerEngine. However, as there's
only one DebuggerEngine at a time that has its data models connected to the
view, there's still some "de facto" notion of a "current" engine. Calling
SomeModel::setData(int role, QVariant data) with custom role is used as the
primary dispatch mechanism from the views to the "current" data models
(and the engine, as all data models know their engine).
Change the WatchWindow handling to be based on quint64 addresses to
ensure proper function. Changed roles and added one role to the
watchmodel to obtain addresses and pointed-to addresses. Add some
fiddling to parse out addresses from debugger values.
Add menu options. Make sure only one watchpoint per address is added.
- Do not reformat boolean values (true,false) as hex/oct.
- char/unsigned char types (cdb/gdb): Chop off the quoted
printable character output by the debugger, pass around integer
only and append the character ourselves in the watchhandler,
making reformatting as hex/octal work.
- cdb: Check format correctly (fix values output as plain integer).
- cdb: Kill needless warning produced by reformatting output of out-of-scope
variables.
- cdb: Display exceptions in the status bar as non-intrusive crash notification.
