In Gtk2 widgets draw themselves in response to the expose event signal.
In Gtk3 widgets draw themselves in response to the GtkWidget::draw
signal, and the signal handler gets a Cairo context as an argument.
Convert Gtk::DrawingArea rendering code to respond to the
GtkWidget::draw signal.
This commit is specific to the drawing area in the Partition Info
dialog.
Reference:
[1] Migrating from GTK+ 2.x to GTK+ 3 - "The GtkWidget::draw signal":
https://developer.gnome.org/gtk3/stable/ch26s02.html#id-1.6.3.4.11Closes#7 - Port to Gtk3
Second commit in a series to convert Gdk::GC based drawing to Cairo
based drawing. This specific commit makes the transition for the
graphical partition info widget that is used in the "Information about"
dialog.
Closes!17 - Gtk2 modernisation
There are multiple cases of code wanting to work with the Partition
object directly containing the file system, regardless of whether it is
within a PartitionLUKS object or not. The code had to do something
similar to this to access it:
const Partition * filesystem_ptn = &partition;
if ( partition.filesystem == FS_LUKS && partition.busy )
filesystem_ptn = &dynamic_cast<const PartitionLUKS *>( &partition )->get_encrypted();
...
// Access Partition object directly containing the file system
filesystem_ptn-> ...
Implement and use virtual accessor get_filesystem_partition() which
allows the code to be simplified like this:
const Partition & filesystem_ptn = partition.get_filesystem_partition();
...
// Access Partition object directly containing the file system
filesystem_ptn. ...
Bug 774818 - Implement LUKS read-write actions NOT requiring a
passphrase
It made the code look a little messy, is easily resolved in the build
system and made the dependencies more complicated than needed. Each
GParted header was tracked via multiple different names (different
numbers of "../include/" prefixes). For example just looking at how
DialogFeatures.o depends on Utils.h:
$ cd src
$ make DialogFeatures.o
$ egrep ' [^ ]*Utils.h' .deps/DialogFeatures.Po
../include/DialogFeatures.h ../include/../include/Utils.h \
../include/../include/../include/../include/../include/../include/Utils.h \
../include/../include/../include/Utils.h \
After removing "../include/" from the GParted header #includes, just
need to add "-I../include" to the compile command via the AM_CPPFLAGS in
src/Makefile.am. Now the dependencies on GParted header files are
tracked under a single name (with a single "../include/" prefix). Now
DialogFeatures.o only depends on a single name to Utils.h:
$ make DialogFeatures.o
$ egrep ' [^ ]*Utils.h' .deps/DialogFeatures.Po
../include/DialogFeatures.h ../include/Utils.h ../include/i18n.h \
For LUKS formatted partitions add an encryption section into the
Information dialog and display the type of encryption, path, UUID and
status of the encryption.
The file system section continues to display appropriate file system
details, including the partition graphic with the file system specific
border colour and correct usage. The details will either be of a plain
file system, an encrypted file system, or nothing when there is no open
dm-crypt mapping, leaving the encrypted file system inaccessible.
Should there be LUKS encryption directly within LUKS encryption then the
details of the inner encryption will be displayed in the file system
section. However this configuration will not be further supported by
GParted.
Bug 760080 - Implement read-only LUKS support
When opening the Partition Information dialog, creation of the dialog
object was creating a copy of the partition object to be displayed. If
this was an extended partition it also included recursively constructing
the contained logical partitions too.
Instead, replace the partition object in the Dialog_Partition_Info class
with a reference to it.
NOTE:
In C++ a reference is really just a pointer under the hood. As such,
dereferences of a pointer to an object in the context of needing a
reference to the object doesn't copy the object. It merely initialises
the reference from the pointer.
Specifically, with this prototype:
Dialog_Partition_Info( const Partition & partition );
and the dialog object being constructed in Win_GParted::activate_info():
Dialog_Partition_Info dialog( *selected_partition_ptr );
the partition object is not copy constructed. A reference (pointer) to
it is merely passed to the dialog constructor.
Bug 750168 - Reduce the amount of copying of partition objects
Make the dialog resizable, add a vertical scrollbar to the information
and messages section, and set the initial height to ensure the dialog
fits entirely on an 800x600 screen.
A default height is required because some window managers, such as
fluxbox used in GParted Live, only permit resizing the height by using
the bottom corners of the dialog. If the dialog is too large for the
screen then the user would not be able to resize it.
Note that two default initial heights are used in an effort to minimize
the amount of extra whitespace.

Include guards need to be unique within GParted code and all included
library header files.
http://en.wikipedia.org/wiki/Include_guard#Difficulties
Use this model for all include guards:
#ifndef GPARTED_FILE_NAME_H
#define GPARTED_FILE_NAME_H
...
#endif /* GPARTED_FILE_NAME_H */
Closes Bug #539297 - Make include guards unique
Display the unallocated space in the graphical partition representation
and numeric figures in the Partition Information dialog.
Bug #499202 - gparted does not see the difference if partition size
differs from filesystem size
Some classes contained private attributes which were used only by a single
member function. Such items were moved to the corresponding function implementations
to stress their limited usage scope.
A few unused variables were also deleted.

* improved errorhandling a bit. At the initialscan we store
errors/warnings now in a list per partition and show the in the
partitioninfo dialog.
While executing an operation we collect all libparted exceptions in
a list and attach this list to the operationdetails when everything
is done.
* include/Partition.h,
src/Partition.cc: added 'Glib::ustring mountpoint'
* include/GParted_Core.h,
src/GParted_Core.cc: implemented set_mountpoints() to set mountpoint
in partitions.
* include/Dialog_Partition_Info.h,
src/Dialog_Partition_Info.cc: use Partition::mountpoint instead of
finding it ourselves.
