Gtk::HBox and Gtk::VBox were deprecated in Gtkmm 3.2. Replace with
plain Gtk::Box.
This commit makes the change for Dialog_Base_Partition.{h,cc}.
Closes!25 - Modern Gtk3 - part 1
First part in a series of commits to replace Gtk::OptionMenu widgets
with GParted::OptionComboBox.
This specific commit is about partition alignment combobox.
Closes!17 - Gtk2 modernisation
Struct FS and struct FS_Limits are strongly related to the FileSystem
class, both being return values from members and associated with storing
file system attributes. Move their definitions from Utils.h into
FileSystem.h.
Adds working copy fs_limits member into common Dialog_Base_Partition
class. Changes the internal code in Dialog_Partition_Copy class to use
fs_limits instead of fs.MIN and fs.MAX. The limits are still passed
into the constructor via object of struct FS and it's members .MIN and
.MAX but immediately used to assign to the fs_limits member.
Bug 787204 - Minimum and maximum size of the UDF partition/disk
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 \
The sector_size parameter is unnecessary as the value can be retrieved
from the sector size of the selected Partition object on which the
create new, copy & paste or resize/move operation is being performed.
For the create new and resize/move operations it is trivial as the
existing unallocated or in use Partition object on which the operation
is being perform already contains the correct sector size. For the copy
& paste operation, which can copy across disk devices of different
sector sizes, we merely have to use the sector size of the existing
selected (destination) Partition object rather than copied (source)
Partition object. Hence these relevant lines in the new code:
Dialog_Partition_Copy::set_data(selected_partition, copied_partition)
new_partition = copied_partition.clone();
...
new_partition->sector_size = selected_partition.sector_size;
Now use a pointer to the Partition object in Dialog_Base_Partition class
and derived classes, Dialog_Partition_{Copy,New,Resize_Move}. This is
equivalent to how the Partition objects are managed in the Operation and
derived classes.
The Partition object is allocated and copy constructed in each derived
classes' set_data() method, called from each constructor and deallocated
in the destructors. Considering the remaining Big 3, these classes are
never copy constructed or copy assigned so provide private definitions
and no implementations so the compiler enforces this.
Bug 759726 - Implement Partition object polymorphism
Return newly constructed partition object by reference rather than by
copy from the Copy, Resize/Move and New dialog classes. This is another
case of stopping copying partition objects in preparation for using
polymorphic Partition objects. In C++ polymorphism has to use pass by
pointer and reference and not pass by value, copying, to avoid object
slicing.
The returned reference to the partition is only valid until the dialog
object containing the new_partition member is destroyed. This is okay
because in all three cases the returned referenced partition is copied
into a context with new lifetime expectations before the dialog object
is destroyed.
Case 1: GParted_Core::activate_paste()
Referenced new_partition is copied in the OperationCopy constructor
before the dialog object goes out of scope.
Operation * operation = new OperationCopy( ...,
dialog.Get_New_Partition( ... ),
... );
Case 2: GParted_Core::activate_new()
Referenced new_partition is copied in the OperationCreate
constructor before the dialog object goes out of scope.
Operation * operation = new OperationCreate( ...,
dialog.Get_New_Partition( ... ) );
Case 3: GParted_Core::activate_resize()
Temporary partition object is copied from the referenced
new_partition before the dialog object goes out of scope.
Partition part_temp = dialog.Get_New_Partition( ... );
Bug 757671 - Rework Dialog_Partition_New::Get_New_Partition() a bit
The member variable was named selected_partition. It is assigned from
Win_GParted::selected_partition_ptr (which is a pointer to a const
partition object so is never updated). This gives connotations that it
won't be modified.
However it is updated freely as the new resultant partition object is
prepared before being returned from the dialog, most notable in the
Get_New_Partition() methods.
Therefore rename from selected_partition to new_partition.
The code goes like this:
Dialog_Partition_Copy::Get_New_Partition()
call Dialog_Base_Partition::Get_New_Partition()
Update this->selected_partition with results from running
the dialog.
return this->selected_partition by value.
Save value back to this->selected_partition.
Update this->selected_partition some more.
return this->selected_partition by value.
So there is an unnecessary copy of the partition object returned from
the base class Get_New_Partition() function back to the same variable in
the derived copy class Get_New_Partition() function.
Need to keep the base class Get_New_Partition() function as derived
class Dialog_Partition_Resize_Move uses that implementation as it
doesn't override it, and it's part of the interface.
Avoid this unnecessary copy by moving base class Get_New_Partition()
code into a new private function, called prepare_new_partition(), which
doesn't return anything. Then have Get_New_Partition() in both classes
just return the required partition object. Like this:
Dialog_Base_Partition::Get_New_Partition()
call prepare_new_partition()
return this->selected_partition by value.
Dialog_Partition_Copy::Get_New_Partition()
call Dialog_Base_Partition::prepare_new_partition()
Update this->selected_partition some more.
return this->selected_partition by value.
Bug 750168 - Reduce the amount of copying of partition objects
This commit from 2010-05-20 removed use of cylinder size increase in the
minimum, and cylinder size decrease in the maximum file system sizes
from the resize/move dialog.

Add partition alignment option to align to MiB (#617409)
This cylinder size limit adjustments were being performed using the
Dialog_Base_Partition::BUF member variable. Now in the
Dialog_Partition_Resize_Move class it is never accessed, and only
unnecessarily set. Move BUF from the common base class into the
Dialog_Partition_Copy class where it is still used.
Bug 749867 - Some limits are adjusted by arcane cylinder size amount
when copying and resizing in a single operation

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
Steps to reproduce:
1) Open any of these dialogs: Create New Partition, Resize/Move or
Paste;
2) Update any of the following numeric entry fields to a different value
using the keyboard: Free space preceding, New size or Free space
following;
3) Press [Esc] key;
Gparted crashes.
What is happening is that the [Esc] key is leading to the dialog being
closed and calling the ~Dialog_Base_Partition() destructor. However
after this the GTK widget is calling the on_spinbutton_value_change()
registered callbacks for the change to the other two values, on the now
just deleted object.
Fix by disconnecting the change notification callbacks in the
destructor.
Closes bug #682658 - GParted crash by pressing Esc in dialogs with
number entry
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.

Make align to MiB the default setting instead of align to cylinder.
Migrate logic for alignment to cylinder into its own method
snap_to_cylinder, and place common logic in snap_to_alignment.
Add alignment checks for situations where space is needed for Master
Boot Record or Extended Boot Record.
Adjust ranges on spin buttons according to required boot record space.
Copy fix for off by one sector (#596552) from
Dialog_Partition_New::Get_New_Partition to
Dialog_Base_Partition::Get_New_Partition
Enhance resize / move logic for checking locations of nearby logical
partitions to not depend on the partition ordering.
Note: This commit does not include limiting graphic movement according
to required boot record space.
Also add signal handler to alignment menu to update file system
minimum size.
This enhancement is to prepare for adding a third alignment
option to align to MiB.

Add my own copyright entries for files in which I changed source
code. Files in which I only made spelling changes do not have my
copyright entry added.
* include/Device.h,
include/Dialog_Base_Partition.h,
src/Dialog_Base_Partition.cc: replaced 'long' with 'Sector' to
prefent overflows with really large devices.
* include/Dialog_Base_Partition.h,
src/Dialog_Base_Partition.cc,
src/Dialog_Partition_Copy.cc,
src/Dialog_Partition_Resize_Move.cc: Fixed bug in copy functionality (due to unset ORIG_START startsector wasn't set correctly). Also have ORIG*
initialized in ctor of dialogbase to prevent such errors from ever happening again (this one only showed up with gcc-3.3.5) .
* added MIN and MAX to filesystemstruct to set min. and max sizes of a filesystem. So instead of checking per filesystem
i now simply check the fs.MIN or fs.MAX. this results in less and cleaner code. Also this will come in handy when adding
support for new filesystems. (This also fixed several minor bugs with filesystemsizes and gained some improvement in resizer
performance)
* Rewrote a large part of gparteds internal code. Filesystemssupport is now much more separated from the rest of gparted and
adding support for other filesystems should be a piece of cake now (hope that's true :P)
It still needs a lot of love, but the foundations are laid =)
