+Dabo 0.9.0 (2008-12-10) Revision 4816):
+===============================================================================
++ Removed the conditional import on the decimal module, as we are now
requiring Python 2.4.
+
++ Removed bare 'except:' from the code. Errors are now explicitly caught and
handled. This allowed us to identify and fix several insidious bugs that were
suppressed by these bare exception handlers.
+
++ Major re-write to the dDialog subclasses. Specifically, there is now a
subclass called 'dStandardButtonDialog' that can accept one or more of the
following parameters when it is created:
+ OK
+ Cancel
+ Yes
+ No
+ Help
+It uses the wx standard button sizer methods to create the buttons following
platform-specific layout guidelines. Each button has a corresponding on* (e.g.,
onYes, onHelp) handler which is called when the button is clicked.
+
++ There are two subclasses of dStandardButtonDialog included: dOkCancelDialog,
and dYesNoDialog. dOkCancelDialog is pretty much the same as before; while
dYesNoDialog is like dOkCancelDialog, except with Yes/No buttons. If you call
dStandardButtonDialog without passing any parameters, a single OK button will
be displayed.
+
++ Removed the ReleaseOnEscape property from dDialog. Added the CancelOnEscape
property to dStandardButtonDialog; when this is True (default), pressing the
Escape key will be handled by the appropriate standard button handler.
+
++ Re-instituted the ButtonSizerPosition property.
+
++ Deprecated onOK() and onCancel(). The methods that will be used by
developers to react to standard buttons being clicked are now named run*; e.g.,
runOK(), runHelp().
+
++ Fixed a bug that has been around in dDialog for years. It used to be that
pressing the Escape key destroyed the dialog if ReleaseOnEscape was True; the
code in the class would still try to access the now-destroyed object, throwing
an error. Now dialogs are never destroyed in these classes; if you create them,
you have to manually call their release() method.
+
++ Changed the default for output to not print all the infoLog messages to
stdout. Instead, infoLog messages are ignored unless the dabo.verboseLogging
setting is set to False. The errorLog still prints to stderr, of course.
+
++ Added the FloatingPanel property. This references a borderless dialog that
can be used similarly to a context menu, but which can contain any controls you
want. Additionally, it will guarantee that it is displayed completely within
the available screen real estate.
+It has two properties itself:
+ Above: by default the dialog is positioned below its owning control.
This changes the behavior so that it is positioned above the control.
+ Owner: this is the control used to position the dialog.
+Typical usage (written in a custom control):
+ fp = self.Form.FloatingPanel
+ fp.clear()
+ # Add controls
+ ctrl = dabo.ui.dTextBox(fp, ...)
+ ctrl2 = ...
+ # Set the Owner to the control
+ fp.Owner = self
+ fp.show()
+The controls in the FloatingPanel should hide or release it, depending on
whether you expect to re-use it. See the update to dDateTextBox for an
implementation of it.
+
++ Re-write the way that the calendar is displayed. It now is contained by the
FloatingPanel of the form, and thus is not bound by panels or other container.
+
++ Also added the ExtendedCalendar property. When True, the larger version of
the calendar control is used. This version has additional controls for quickly
moving to any date.
+
++ Added the method 'resolvePathAndUpdate()' to dabo.ui. This introduces much
more robust path resolution, especially in cases where files are within a
project structure. It also allows to dynamically updated files via the changes
in dApp.
+
++ Changed several of the creation routines to use resolvePathAndUpdate().
+
++ Changed several 'has_key()' calls to try/except structures. Profiling showed
has_key() to be very slow. It is also deprecated for Python 3.0
+
++ Changed the way 'special' items are handled in menus. Previously, the only
way that the About and Preference menu items were handled on OS X was some
special code inserted in dBaseMenuBar. That code is now abstracted out to dMenu
and dMenuItem; there is now an additional parameter that can be included called
'special': right now, the only special item is 'pref', indicating the
Preferences menu. The About menu is keyed off of the id of wx.ID_ABOUT. If
either of these two cases are found, the appropriate Mac-specific menu handling
will occur.
+
++ Added 'scrollVertically()' and 'scrollHorizontally()' methods to
dScrollPanel, allowing for external scrolling.
+
++ Added the 'SourceURL' property to dApp, along with the 'urlFetch()' method.
The main idea behind this is that if this property is filled in, calls to
dabo.ui.resolvePathAndUpdate() will also check the URL specified in SourceURL
for updates to the file, enabling more dynamic deployments. This feature is
largely untested and should be considered experimental for the time being.
+
++ Added a call to resolvePathAndUpdate() to the DesignerXmlConverter.
+
++ Removed all the deprecated code for 0.9.
+
++ Added a property entry for ShowColumnLabels for a dGrid in the ClassDesigner.
+
++ Moved the Transparency property from dFormMixin to dPemMixin, as it is
possible to set it for individual controls. This doesn't break any existing
uses at the form level, but enables control-by-control adjustment of
transparency.
+
++ Added pageUp, pageDown, pageLeft and pageRight methods to dScrollPanel.
+
++ Changed the 'LineNumber' property in dEditor to be one-based, to match the
displayed line numbers in the editor. Added the '_ZeroBasedLineNumber' property
that does the actual communication with the wx layer.
+
++ Added the TransparencyDelay property. It is simply eye candy; it smooths out
changes in transparency over the time specified in this property (default=0.25
sec.).
+
++ Changed strToBmp() to use app.HomeDirectory as the cwd, if there's an app
defined, as app.HomeDirectory always refers to the app's root directory, even
if the cwd is somewhere else, even if the app is frozen with py2exe.
+
++ Added the 'afterFinish()' hook method. This fires after the app has
terminated, allowing you to do cleanup stuff in the app instead of in the
calling program.
+
++ Moved the 'getPositionInSizer()' method to the module level, allowing it to
be called for any object, even a non-Dabo item. Changed the version in
dPemMixin to call the module method.
+
++ Fixed an error when using a bizobj without a data connection.
+
++ Added VisibleOnScreen property to all ui controls. This is a read-only
property that tells you if the object is actually visible or not, taking into
account visibility of parent objects and sizers.
+
++ Fixed the datanav2 Grid to only process the double-click if it happened in
an actual cell. Prior to this, I was getting NoRecordsException from my app
when the user double-clicked an empty grid. Also, clicking in an area of a grid
with no cells will no longer do the processEditRecord(), which is what we
really expect.
+
++ Enabled skipping the dialog-ending behavior by returning False from the
runOK/Cancel/Yes/No methods.
+
++ Added before- and after- hooks to the onEditPreferences() handler, enabling
you to hook into preference changes and fire any appropriate update code.
+
++ Added the Borderless property. When True, the dialog will have no title bar
or border.
+
++ Updated dApp to optionall raise a 404 Not Found error if a requested file is
not found from urlFetch(). Also fixed a potential bug in which setting the
SourceURL property could get erased by the init code in dApp.
+
++ Updated the resolvePathAndUpdate() method of dabo.ui to also check for code
files when updating a .cdxml file.
+
++ Added the 'webHeaderFormat()' method that takes a datetime value and returns
a formatted string that conforms with the standard expected by HTTP headers.
+
++ Extended the handling of attProperties to all classes, not just those that
inherit from dPemMixin. This was the cause of the problems reported by Nate
Lowrie regarding grids created in the ClassDesigner, since dColumn is
subclassed directly from dObject, and setting the properties of dColumn objects
from attProperties was not being handled.
+
++ Added an EOLMode property. The property the is stored as a string and
allows you to set the EOLMode of the file to CRLF, LF, or CR standards. If not
explicitly set by the user, the standard will default to the OS standard. Upon
setting the EOLMode, all end of line markers are automatically converted to the
new standard.
+
++ Tracked down and found the errors associated with the dMenu problems I was
having. The main problem was that in the mnxml files, a Caption and Hotkey
would be specified separately, but they would be combined into the Caption
property by createMenuBar and that would cause a slew of problems. In
addition, if you had a Caption w/ a hotkey in it and then specified the hotkey
property, wx would have a conniption fit. I added a check to the Caption
property to raise an error if the Caption has a HotKey in it.
+
++ Removed the raising of the ValueError if you set a menu item Caption in the
form of "Open\tCtrl+O". Instead, simply override any existing HotKey with the
hotkey provided in the string, and only set the caption part to the Caption
property.
+The only potential problem with this is in this example:
+item.Caption = "Open\tCtrl+O"
+...
+item.Caption = "Close"
+In this case, the item will still have the Ctrl+O hotkey, and if you didn't
want a hotkey, you'd have to then set it explicitly with:
+item.HotKey = None
+
++ Added explicit setting of Accepted to False to the _onCancel() and _onNo()
methods. If a dialog was re-used, and Accepted was set to True in the first
use, clicking Cancel the second time resulted in Accepted=True again, which is
not correct.
+
++ Added features similar to the bash history and reverse-i-search to the
shell. Pressing Ctrl-R will bring up a dialog containing your previous
commands; you can type to filter only those containing your search string. You
can then press Enter or double-click on the command, and it will be entered
into the shell.
+
++ For some reason, the dShell form was intercepting key characters with
"Ctrl+Character" and stopping the KeyDown event from firing on Windows. Now,
instead of catching the KeyDown event and looking for the specific sequence,
the form's bindKey method is used instead. This works on Windows. I have
bound cmd+R to Mac, but I need someone to test the changes.
+
++ Fixed a typo in _LookupPanel's onListKey. dKeys.arrows should be
dKeys.arrowKeys. arrowKeys is a dict, so we need to reference values. Again,
test the changes on Mac.
+
++ Changed the key binding for the history search to be Ctrl-R on all
platforms. On the Mac, Cmd-R is the 'Redo' command, and anyways, the Mac
Terminal works just like Linux terminals, in that Ctrl-R is what is used to
bring up command history searching.
+
++ Added a new class dDropTarget. The drop target using the
wx.DataObjectComposite class to be able to handle both files and text drops.
The class is built to allow for easy interfacing with the DroppedTextHandler
and DroppedFileHandler properties in dPemMixin.
+
++ Modified the DroppedTextHandler and DroppedFileHandler properties to support
the new drop target. User code shouldn't need to change.
+
++ Revamped the code for how file extension limits are handled in the getFile
classes. Instead of hardcoding the allowed types into the
dabo.ui.uiwx.__init__.py file, I've moved them to a dict in dabo.settings. I've
also added an empty dict named 'custom_extensions' to dabo.settings that can be
used by developers in case they want to add additional extensions with custom
descriptions.
+
++ Added code to prevent saving a file that has been modified on disk since it
was opened in the editor.
+
++ Added the method checkForDiskUpdate(). This will return True or False,
depending on whether the file on disk has been modified since it was opened in
the editor.
+
++ Added the isChanged() method as a wrapper around the wxPython GetModify().
+
++ Moved the dDropTarget class definition into dPemMixin.py, and renamed it
_DropTarget. The reason is that this is a wxPython-specific implementation
detail, and we don't want to expose this as a Dabo base class to users.
+
++ Added the 'colorNameFromTuple()' method. Given an RGB color tuple, it will
return a list of the common names for that tuple, or an empty list if there is
no match. If the 'firstOnly' parameter is passed as True, only the first
element in the list will be returned as a simple string value, or an empty
string if there are no matches.
+
++ I found the filt argument to setAll() to be hard to use: the expression has
to be written so that the leftmost word is a member of the current child object
being evaluated, and any names in the expression need to be local to dPemMixin,
not the caller. So the simple case in the docstring works, but how to evaluate
if the child is an instance of my special subclass?
+I couldn't do filt="'TxtFraction' in str(BaseClass)" because of the
requirement that the left-most word must be an attribute or member of the child
being evaluated.
+I couldn't do filt="BaseClass == TxtFraction" because TxtFraction doesn't
exist in dPemMixin's namespace.
+So, I added a instancesOf argument, that accepts a single or sequence of
class(es), and added logic to setAll() to handle this. It shouldn't have any
effect on current uses of filt, but I feel this better satisfies the common
case of wanting to call setAll() only on instances of specific classes.
+Perhaps an improvement to filt would be to add a placeholder, instead of it
being fixed to the left. Another improvement could be to pass in the locals
and/or globals to setAll(), so the eval() takes place in the environment of the
caller.
+
++ I added two user level hooks to dDialog called beforeAddControls and
afterAddControls. If you design a dialog in the ClassDesigner, addControls is
already used internally by the framework to add the controls. So, both these
hooks make it possible to add controls afterward and set the dialog's sizer
properties before.
+
++ This commit fixes some problems with the menu hot key editor in the
preference pages. First, fixed the issue where the clear key button wasn't
getting updated after clear and set events. Second, if you cleared a key using
the clear key button, that key wasn't clear from the hotkey map so if you tried
to set a control with the cleared key combo, it would give you an erroneous
warning. Fixed that. Last, if you clicked the cancel button, you menu changes
were not rolled back. Fixed that.
+
++ Fixed the submenu display problem when using mnxml format. Instead of
creating a dMenu with no parent, we would create a menu with the menubar as the
parent and that would lead to trying to set the top label upon setting the
caption which we don't want.
+
++ Finally fixed the bug in the Mac font scaling logic. The problem is that
when *any* font property changed, the font would be re-set, and the scaling
factory re-applied, making the font size shrink. Now it keeps track of when it
applies the scaling, and only re-applies it if a different FontSize value is
passed.
+
++ Made it simple to create custom grid editors using Dabo controls.
+To create the editor, just pass the control that you want to use to
dabo.ui.makeGridEditor(). It will return a class that you can then assign to a
column's CustomEditorClass property.
+Since editors by default will be sized to the grid cell they are editing, I
added two optional parameters to makeGridEditor(). You can pass 'minWidth' and
'minHeight' values; the class will then ensure that the editor is displayed
with at least those dimensions.
+
++ Renamed the dFoldPanelBar/dFoldPanel classes to
dSlidePanelControl/dSlidePanel, repectively. Added deprecation warnings if the
old names are used.
+
++ dColors adds randomColorName(), which returns a random color name instead of
a random color tuple. dEvents has been updated to use the dSlidePanelControl
naming.
+
++ The setDefaults method of dEditor was interfering with the setting of the
FontFace and FontSize properties from application. It would override the
settings on the Wx level. So, I pulled the setting of the font out of
setDefaults and merged it with the setting of the font from the preference
setting. If there is a preference setting, it will be used. Else, the face
and size used are the defaults specified in the module level variables fontFace
and fontSize.
+
++ Fixed a long-standing bug in this composite control. There were several
situations where it appeared that the spin buttons stopped responding to
clicks, even though the displayed value was within range. The problem turns out
to be that while we were correctly setting the textbox's value, we were not
setting the spinner's value; instead, it was incrementing by +1/-1 for each
click. This commit fixes that problem by eliminating the spinner's settings
from the mix; instead, we govern min/max/wrap through our own code.
+
++ I also fixed the problem with the collision between float and Decimal
values. All values in the comparisons are now cast to the type of the edited
value when there is a conflict.
+
++ Fixed the missing docstring for the class, and added some other docstrings
to methods.
+
++ Renamed dSpinButton to _dSpinButton, as it is not meant to be a public
class, and is not available in dabo.ui.uiwx.__init__.py.
+
++ Fixed up the setting of KeyValue in dControlItemMixin, so that if KeyValue
is getting set to a non-existent key, the control will have nothing selected
and the Value will be None. This I believe was the intent all along but
visually, at least dDropdownList wasn't doing it, and confusing infoLog
messages were being generated.
+
++ Changed KeyValue in subclasses of dControlItemMixin to raise a ValueError if
you try to set the Value to a non-existent key.
+
++ Changed the name of dCheckListBox to dCheckList, which is consistent with
dRadioList. Deprecated the old name, and fixed all references.
+
++ Created a decorator to detect dead objects so that we no longer encounter
wx._core.PyDeadObjectError exceptions. I created it in the dabo.ui module, as
it needs to be able to be referenced during loadUI().
+
++ Replaced the dead object trapping code in dGrid.py and decorated the
affected methods instead.
+
++ Fixed much of the flickering problems with dGrid on Windows, which had to do
with the way we were painting the grid header. Reworked it to be called from
EVT_PAINT instead. Played around with various options such as using a PaintDC
or a BufferedPaintDC, and overriding EVT_ERASE_BACKGROUND, but the tradeoffs
weren't worth it. As it is, I don't know if I haven't harmed Linux or Mac.
+
++ Changed the "Please wait... requerying dataset" busyinfo to just push it to
the StatusText.
+
++ [3996] and [3998] added property TabStop, which when True allows focus to
the control (the default). However, I've run into oddities when creating panels
with some controls with TabStop=False. Turns out, I was calling Navigate()
without a needed argument, the event needs to be skipped, and the Navigate()
needs to be done in a callAfter().
+
++ Implemented a basic debugging output window. It's fairly simple now, but can
be customized further based on feedback.
+
++ There is a new menu item in the base menubar class "Debug Output Window".
It's designed to be a checked menu item, but the check always appears to be out
of sync with the debug window. Selecting that menu shows/hides the debug output
window.
+To add debug output, add this line to your app where you want to record
information:
+ debugout("Some stuff")
+You can add multiple items, much like the print command, and they will be
output with a space separator
+ debugout("Status", self.status)
+
++ Fixed the issue with AutoIndent not working. The issue was that
GetLineIndentation wanted wx's zero based line number instead of the 1 based
line number we use. We were using the 1 based line number, and the indentation
level of the new blank line was returned and always zero. This fixes that.
+
++ Added a new property to the dEditor widget which exposes the ability to show
indentation guides. The property is called ShowIndentationGuides.
+
++ Improved VirtualFields by adding the option to set a given VirtualField to a
dict instead of a function. Currently, this dict has one required key, "func",
that stores the function object, and an optional key, "requery_children", that
determines whether or not child records are requeried before the virtual field
function is run.
+
++ Changed default behavior to *not run* the child requeries, as this was a
performance hog for an uncommon case. If your VirtualFields function requires
that child records have been requeried before running, then you can either
requery them inside the function itself, or define the VirtualFields like the
following:
+old:
+ self.VirtualFields["myfield"] = myFunc
+new:
+ self.VirtualFields["myfield"] = {"func": myFunc, "requery_children": True}
+
++ Worked around a substantial source of the flickering of dGrid on Windows, by
caching the cell values for 10 seconds to avoid unneccesary calls to
biz.getFieldVal(). This will probably improve performance on Mac and Lin as
well, even though those platforms didn't exhibit the flickering. Now, the
windows grid will flicker at most once every 10 seconds. Call grid.update() or
grid.refresh() will clear all cached values immediately.
+
++ Added the deleteByValue() method to dPref. This enables you to delete all
pref entries that contain the passed value.
+
++ Updated dShell so that if you re-use a command from its history, the old
entry for the command is deleted. The effect is that the history only contains
one instance of each command, with the most recent usage at the top.
+
++ When calling getPrefs(), you can now indicate a key that is relative to the
current pref by prefixing it with a period.
+
++ Deprecated the SQL property. It now issues a deprecation warning, and then
passes the values through to the UserSQL prop.
+
++ Added 2 new properties to the dEditor widget. They are ShowEdgeGuide and
EdgeGuideColumn. Basically, ShowEdgeGuide will display a line at the specified
column position. Note that if the editor has a variable spaced font set, wx
uses the average of the characters' widths to determine where to put the line.
Also note that wx will only allow for either HiliteCharsBeyondLimit or
ShowEdgeGuide to be True, not both. So, when one is set to True, the other is
set to False.
+
++ Removed the setting of UserSQL when setSql() called without arguments.
Removed setting the SQL property, and instead set UserSQL directly.
+
++ Changed the superclass of dEvent from dObject to the base Python object
class.
+
++ Fixed the goNextBookMark and goPrevBookMark function. The mask trouble was
that the marker identifier is really a bit in a marker mask. Since, _bmkPos
was 5, it was the 5th bit which corresponds to the integer value 32. So, by
doing a left shift on the marker, we can get the proper mask.
+
++ Also, fixed the issue with zero based line numbers and the line number being
off by one. Furthermore, if there was a marker on the line, we had to move to
the next line to search otherwise MarkerNext would return the line to search
from.
+
++ Wrapped the wx.Toolbook class. It's another dPageFrame like widget, only it
uses a ToolBar instead of tabs. Things to note:
+
++ Images must be 32x32 or they fail to add (same as the other page frame
widgets except they are 16x16). Also, images cannot be changed after a page is
created.
+
++ Wrapped the wx PlateButton widget into Dabo. Everything works and is
tested. I did a minimalist wrap for the things I needed. If somebody wants
another feature wrapped, let me know. I called it dBorderlessButton because it
seemed to fit well.
+
++ Fixed the bug that failed to discern that a new record with a
manually-populated PK was in fact new. Thanks to Dr. Sibylle Koczian for
reporting this and working with me to help track it down.
+
++ Tracked down and fixed the problem that caused all those 'GTK-Critical'
messages.
+
++ Added an 'OK' button to make it clear how to dismiss the dialog when running
under a window manager that does not have a title bar present.
+
++ Refactored the imports to better catch cases where simplejson is not
installed.
+
++ Changed the way that 'IsAdding' is determined to take into account
manually-entered PKs.
+
++ Added a fix to dSizerMixin when setting the Spacing property - sometimes the
value can come from the edited grid cell in the Property sheet as a string
instead of an int. I think I fixed the prop sheet, but I left this fix in just
in case.
+
++ Fixed a problem when running designs containing unfilled LayoutPanels. The
default settings of the panel were being ignored, resulting in a zero-sized
panel in the runtime.
+
++ Worked around an apparent bug with MDI Child Windows on Mac, where calling
Maximize(False) will maximize instead of restore the window.
+
++ Fixed the status bar displaying "Record 1/0" when there are no records.
+
++ Fixed status text to still go to the MDI child form on Mac, instead of the
MDI parent. On Mac, the MDI parent frame isn't shown and the children are still
fully SDI so the whole MDI thing is kind of a misnomer.
+
++ Fixed dGrid.addColumn() to accept not just a custom dColumn instance, but
also a custom dColumn subclass, which it'll instantiate with any passed
property settings. If an instance is passed, the properties will be applied to
the instance.
+
++ Added [Dynamic]CellBackColor property to dColumn.
+
++ Commented out the code that allows for an optional main panel to be added to
a form upon creation. I left the code in while we test existing code, but I
haven't found anything in the framework that uses this. Trac issue #1033.
+
++ Modified the firing of the Hit event when the slider is set to
Continuous=True. Now it will only fire if the underlying value changes. This
may be what was responsible for Trac Issue #1054, in which multiple events were
recorded.
+
++ Fixes the issues noted in Trac #1114: WordWrap was not showing properly on
Mac and Windows when a label was initially shown.
+
++ Changed the order that the update() steps are carried out. I had noticed a
bug in some of my Dynamic* properties that depended on the control's Value. The
cause was that the dynamic props are evaluated *before* the Value gets updated.
+
++ Moved the sizer default logic into the DesignerUtils script.
+
++ Enhanced the getDefaultSizerProps() method to handle the mangled names that
the Class Designer sometimes creates.
+
++ Changed the way that the import statement block is handled in the .cdxml.
This *should* be backwards-compatible, but may require re-creating your import
statements in your design.
+
++ The change was required because the previous code sometimes resulted in
import statements not being run before code that depended on those names was
called.
+
++ Added the dabo.ui.spawnProcess() method. This allows to to run another
application in a completely independent process.
+
++ Added the method 'appendDataSet()'.
+
++ This fixes the issue with the Font property and dMaskedTextBox. We were only
checking for the existence of a '_font' attribute, and apparently the masked
classes defined that att themselves.
+
++ Changed the field validation so that it is triggered by any call to
flushValue(). Previously it only fired on LostFocus events, meaning that you
could set the Value directly in code without validation.
+
++ Fixed the call to activeControlValid() to only be made if there is an active
control, and it's not the current control.
+
++ added support to allow the retrieval of un-masked values or masked values
for the dMaskTextBox.
+
++ dApp wasn't allowing the setting of a custom Crypto instance in
initProperties, because it was reinitializing self._cryptoProvider to None
*after* the custom Crypto was already set by the user. Fixed, by taking away
the unneeded assignment in __init__, and adding a getattr() wrapper in
_getCrypto().
+
++ Changed the default for SQLite to not create the database file if it doesn't
already exist. This setting is controlled by dabo.createDbFiles, which defaults
to False.
+
++ Added dException.DBFileDoesNotExistException class. This is raised if you
try to connect to an SQLite file that does not exist and dabo.createDbFiles is
False. This exception can be caught in the calling routines and handled
appropriately. dConnection now takes an optional constructor parameter
'forceCreate'; if that is True (default=False), the db file will be created no
matter what the system setting is. dbSQLite.getConnection() takes that same
parameter, and passes it to the connection constructor. dPref, which is
supposed to create the DaboPreferences.db file no matter what, has been
modified to pass forceCreate=True to the connection.
+
++ Added the improvement provided by 'cowo' for proper importing of project
subdirectory modules. Added the method 'getStandardAppDirectory()'. This takes
one of the following standard Dabo directory names and returns the path to that
directory. It takes an optional path location to start looking from; it will
also search the app's HomeDirectory. The standard directory names are:
+"biz", "cache", "db", "main.py", "reports", "resources", "test", "ui"
+If the user requests a non-standard directory, a message is printed to the
errorLog and None is returned.
+If the specified standard directory cannot be found, None is returned.
+
++ Removing the deprecated first datanav classes.
+
++ Moved the datanav2 code into 'datanav'. Modified the datanav2 __init__.py to
import datanav classes so as not to break existing references to datanav2.
+
++ Improved the handling of empty datasets. No longer will exceptions be
raised; instead, None will be returned on an execute against an empty dataset,
and the original will be returned on a filter on an empty dataset.
+
++ Added an afterSetup() hook method at the suggestion of Henning Hraban Ramm.
+
++ Added the ValueMode property to dMaskedTextBox. This will control whether
the Value property returns the masked value or the plain value. Default is
plain.
+
++ Improved the import logic in test.py. Also fixed the import of
dBorderlessButton so that when it is run inside of test.py it doesn't break the
test.
+
++ Added a check for non-date values in dDateTextBox to prevent the errors
reported earlier this week.
+
++ Reworked the column.Visible functionality, and as of now it displays the
test correctly in dGrid, although I'm sure I've missed some things. I tested on
Linux.
+
++ Changed the way that the Visible property works with columns. Now the column
is not removed from the grid's Columns collection; instead, its Visible status
is taken into account when drawing the grid.
+
++ Added the 'addSizerDefaults()' method. This is to be used by external tools
to set defaults for controls that are not part of dabo.ui.
+
++ Found a case where a Designer tool (the view palette) had controls that were
bound to properties that not all the controls they were modifying had. This may
be related to some of the abends encountered when using the View Palette on
Windows and Linux.
+
++ Improved the drag/drop behavior of grids.
+
++ Fixed Bottom and Right properties to get set after the wx object is fully
instantiated. Thanks to Alex Tweedly for reporting the issue.
+
++ Implemented the ResetPageNumber property of reportwriter group objects. If
it evaluates to True, the page number will be reset when the group expr
evaluates differently.
+
++ Added PageNumber read-only (runtime) property of the Report object,
accessible from report designs by 'self.PageNumber'. For example, put this in
an expr for a string object:
+ "Page %s" % self.PageNumber
+This is just the first step. The PageNumber at this point will just keep
incrementing with no way to reset it during the report run.
+
++ Added handlers in the UI layer for some of wxPython's AppleEvent handler
methods. These catch the methods and propagate them to the dApp layer, where
they can be overridden in an app subclass.
