RELEASE NOTES AND CHANGES
NAME
Win32::GUI::ReleaseNotes::RN_1_06 - release notes for v1.06 of
Win32::GUI
Release Date
13th February, 2008.
Summary of Changes
This is a summary of changes between V1.05 and V1.06 See the
CHANGELOG
file in the distribution for the full detail.
This release is a primarily a bug-fix release addressing the
issues
below. There are a small number of new features. Minor changes
have been
made to enable correct building with the new perl 5.10.0
Please note that this is intended to be the last release that is
compatible with the Perl 5.6 series.
New Features
More constants
Win32::GUI::Constants now has over 2000 constants. Please keep
reporting any that you need that are missing.
Win32::GUI::DC::DrawFrameControl can DFCS_ADJUSTRECT
DrawFrameControl() will now adjust it's input parameters if
the
DFCS_ADJUSTRECT flag is set and the input parameters are not
readonly.
Dialog navigation for MDI Windows
Salvadore Oritz submitted a patch to allow 'TAB' navigation
between
controls of an MDI child window. The '-dialogui' is now
functional
on MDI child windows.
Confusion with GetParent() and TreeView windows
The GetParent() method usually gets the parent window, but for
the
Treeview class it gets the parent node:
$parent_node = $tree_view->GetParent($node);
This made it difficult to get the parent window. Now, if the
GetParent() method is called without an arguements it returns
the
parent window:
$parent_window = $tree_view->GetParent();
Bug Fixes
Balloon Tooltip info and warning icons swapped
The info and warning icon for balloon tooltips were the wrong
way
round. This is fixed. (Tracker: 1709017)
Textfield::GetLine() truncates lines
Textfield::GetLine() has been re-written to stop it truncating
lines, and to correctly return empty lines.
'-prompt' option to Textfield
The '-prompt' option to the Textfield constructor would
generate
warnings and place the label incorrectly when used to supply a
label
only:
-prompt => 'Some Label:',
This should now be fixed. Note that if you were relying on the
previouly incorrect placement (always against the left
border), then
you may need to re-position your labels. (Tracker: 1734697)
Warning During Global Destruction
It was common to get a warning like:
(in cleanup) Can't call method "DELETE" on an undefined
value at C:/Perl
/site/lib/Win32/GUI.pm line 3451 during global destruction.
This is now, hopefully, fixed. Please report if you still see
errors
like this.
Memory leaks
Various memory leaks have been resolved.
Win32::GUI::Scintilla buffer sizes
There were several places in the Scintilla wrapper code where
buffers of the wrong sizes were allocated. This has been
fixed.
Win32::GUI::Scroll return value
On failure Win32::GUI::Scroll was supposed to return undef,
but was
returning random garbage. This has been fixed, along with
updates to
the documentation.
Win32::GUI::RichEdit::LimitText()
There was a typo in the function name (LimiteText()). Both
spellings
are now supported.
ListView BeginLabelEdit event
The second argument was being set incorrectly when the
callback was
made. This is now fixed. (Tracker: 1706901)
ListView SelectedItems may now return an empty list
Win32::GUI::ListView::SelectedItems used to return "undef"
when
there were no items selected. It now returns an empty list, to
better support things like:
for my $item ($listview->SelectedItems()) {
# do something with the selected $item
}
TreeView::GetItem may now return an empty list
Win32::GUI::TreeView::GetItem (and
Win32::GUI::TreeView::ItemInfo)
used to return "undef" when asked about a non-existing item.
In now
returns an empty list to better support things like:
my %node_info = $treeview->GetItem($item);
Crash when destroying a window during a callback
It is possible to write code that destroys a window during one
of
it's one callbacks. This could crash perl. Hopefully this is
now
fixed.
All Win32::GUI::DC::Poly* drawing functions broken
Polygon(), PolyBezier(), PolyBezierTo(), PolyLine() and
PolyLineTo()
now all work.
Comboxbox constructor - using multiple types
The Win32::GUI::Combobox constructor has been updated to
handle the
'-simple', '-dropdown' and '-dropdownlist' options more
intuatively.
The docuentation has been updated to explain that only one of
these
options should be used, and what happens if more than one is
used.
Win32::GUI::Imagelist::AddMasked broken
This call should now work. (Tracker: 1734697)
Win32::GUI::Acceptfiles() generates warning
The AcceptFiles() method was using some undefined constants.
They
have been removed.
Build process fixes
A number of warnings when building under cygwin were fixed -
patches
submitted by Reini Urban.
Win32::GUI::BitmapInline wasn't using a suitable temporary
directory
Win32::GUI::BitmapInline was always using the current
directory to
create temporary files. This failed when the current directory
wasn't writable (likely under limited user accounts in Win2K
and
above). It now uses "File::Spec->tmpdir()" to get a writable
temporary directory. (Tracker: 1586643)
Further, the filename chosen wasn't thread-safe. This
(unlikely)
race-condition should also be fixed.
Toolbar Addbitmap can't be called multiple times
The Win32::GUI::Toolbar::AddBitmap() method failed when called
a
second time, reporting that you couldn't use it when an
imagelist
was already assigned (regardless of whether you had assigned
an
imagelist or not). It may now be called more than once to add
individual bitmaps to the toolbar.
Deprecated feature status
This section documents features that have been deprecated in this
release, or in recent releases, and feature that will be
deprecated in
up-coming releases.
Win32::GUI::Constants
The introduction of Win32::GUI::Constants in v1.04 means that we
now
have access to a very large number of constants, so the v1.03
behaviour
of Win32::GUI to export all constants to the calling namespace by
default is no longer appropriate. So, a bare
use Win32::GUI;
now generates a warning that the old default behaviour will be
deprecated - although the export behaviour of Win32::GUI v1.03 is
maintained except for this warning.
To eliminate this warning and correct your script, do one of the
following:
If you don't need any constants, use the empty list:
use Win32::GUI();
If you need some constants, name them explicitly:
use Win32::GUI qw(ES_WANTRETURN CW_USEDEFAULT); # Two
constants exported
use Win32::GUI qw(/^MB_/); # Export all constants starting
with MB_
See the Win32::GUI::Constants documentation for the full allowable
syntax.
You are advised to fix your scripts now, as a future version will
stop
exporting any constants by default.
Although not advised, you can suppress the warnings by turning
deprecated warnings off:
no warnings 'deprecated';
Additionally accessing constants from within the Win32::GUI
namespace is
deprecated. I.e.
-addstyle => Win32::GUI::WS_BORDER,
will generate a warning with this release, and will stop working
with a
future release. Use one of the following methods instead:
use the Win32::GUI::Constants namespace instead
-addstyle => Win32::GUI::Constants::WS_BORDER,
use any other namespace you fancy
use Win32::GUI qw(-exportpkg => A::B -autoload);
...
-addstyle => A::B::WS_BORDER,
maintain compatibility of existing scripts
use Win32::GUI::Constants qw(-exportpkg =>
Win32::GUI :compatibility_win32_gui);
...
-addstyle => Win32::GUI::WS_BORDER,
Win32::GUI::NotifyIcon
It is no longer necessary to use the '-id' option to any of the
Win32::GUI::NotifyIcon methods. The ID is now entirely handled
internally. You will receive deprecated warnings if you use it.
In particular, removing Icons from the system tray should be done
using
$NI->Remove();
and not by the (now deprecated)
$NI->Delete(-id => 1);
Use of the "-id" option will generate a warning.
