WIn32Lib v0.55
I'm about to release this at SourceForge. But for those interested, here is
a list of the changes in Win32Lib v0.55.
--------------------
Added
onClick is invoked for ComboBox list selections.
Enhanced
getItem() now retrieves the currently selected text from a combo
or list if the second parameter is zero.
eg.
-- Get the currently selected item.
x = getItem(theList, 0)
Fixed
The validId() function now checks for valid parent too.
Fixed.
You can no longer try to run WinMain() after it has run once.
Enhanced
The warning and abort message box now show the application's name
in the title, and the Win32Lib version at the bottom of the message.
Enhanced
The error code 499 now displays the control IDs involved.
Enhanced.
To support older versions of Windows, the DLL linkages now only take
place if actually used by the application.
Replaced
registerw32Library() replaces linkDLL()
registerw32Function() replaces linkFunc()
registerw32Procedure() replaces linkProc()
w32Func() replaces c_func()
w32Proc() replaces c_proc()
Enhanced
The DLL rich20.dll will be used if installed, otherwise rich32.dll is used.
rich20.dll implements RichEdit v3.0 whereas rich32.dll implements RichEdit
v1.0
Renamed
A few routines have been renamed to comply with win32lib naming
conventions.
SetPointerPosn() renamed as setPointerPos()
GetPointerPosn() renamed as getPointerPos()
ClickPointerLeft() renamed as clickPointerLeft()
DragPointerTo() renamed as dragPointerTo()
setPenPosition() renamed as setPenPos()
The old names have been included in the compat01.ew file, which is
automatically included in the win32lib.ew, but will not be when v1.0 is
finally released.
Added
Some alias names for commonly used controls have been added.
CommandButton = PushButton
Button = PushButton
RadioButton = Radio
GroupBox = Group
ListBox = List
ComboBox = Combo
EditBox = EditText
Fixed
Automatic wordwrap has been restored to RichEdit controls. To add it
back, create the control using the WS_HSCROLL flag.
Added
New predefined colors DarkGray, LightGray, Pink, Purple, Parchment
Enhanced
The predefined colors Grey and White are no longer the same shade.
Grey remains unchanged but White is now rgb(224, 224, 224) which is
about halfway between LightGray and BrightWhite.
Enhanced
The validId() function now makes sure the parent id is also valid.
Added
getWindowInfo() to get internal Windows information about a control
getControlInfo() to get internal win32lib information about a control
Enhanced
The flag parameters in create() and createEx() can now be sequences.
And if so, they replace the library defaults for the control being created.
Fixed
TabItems now displayed correctly when the tabs are clicked. The overlayed
items no longer "bleed through".
Fixed.
setWindowBackColor() now works for most control types. However, Windows
overrides
it for some controls, eg. Toolbars, Statusbars, and Buttons.
Fixed
The subclassing error for combo boxes has been permanently fixed.
Fixed
destroy() routine now ignores invalid control ids.
Fixed.
The onDestroy event is no longer invoked twice when destroying a window.
Enhanced
When using destroy() to destroy a Window, the window is now closed first.
This will trigger any onClose handler, allowing the application to reject
the close and thus the destroy request.
Enhanced
setVisible and setEnabled can now accept a list (sequence) of ids as the
first parameter. This makes it easier to manage a set of controls for user
input.
eg.
setEnabled( {List1, Btn2, Btn3}, False)
Enhanced
addItem can now add a list of items instead of just one item at a time.
addItem(theList, {"Apples", "Pears", "Oranges"})
Enhanced
A new form of event handler syntax is available. You can use setHandler()
to establish a routine that will be invoked when specified events happen to
specified controls. Unlike the current syntax, this one allows multiple
controls and/or multple event types to be assigned to a routine at one
time, plus all the handler routines have the same parameter signature,
procedure myHandler(integer self, integer event, sequence parms) .
eg.
procedure buttonpushed(integer self, integer event, sequence parms)
if self = Btn1 then
. . .
else
. . .
end if
end procedure
setHandler({Btn1, Btn2}, w32HClick, routine_id("buttonpushed"))
Fixed.
setBackColor() now calls the Windows library using the DC handle instead of
the Window handle.
Added
setPenBkColor() sets the background color to be used for text characters.
Added
moveZOrder() used to move a window to the front or back of other windows.
Added
refreshWindow() used to forde a window's borders etc to be redisplayed.
Added
distributeControls() used to evenly distribute a set of controls over
some specified space.
Added
sizeControls() used to resize controls relative to another control or
specific value.
Added
alignControls() used to align a set of controls relative to another control
or specific value.
Enhanced
getOpenFileName() and getSaveFileName() now support a control id of zero,
which
means that the parent of the dialog box is the main window in the
application.
Added
setTabCodes() is used to set which keycodes are interpreted as the TAB
character.
Added
setTabEnabled() is used to establish whether or not a given control
responds to the TAB character.
Fixed.
Controls in TabItems now display correctly when the tabitem is selected.
This also allows
for nested tabcontrols.
Fixed.
The F10 key now acts as a normal key arther than a system hotkey.
Enhanced
A combobox changed selection now invokes an onClick for that combobox.
Fixed
A minimized modal window now traps the focus. Previously, minimized modal
windows were ignored.
Added
An onPause event occurs when the pause key is pressed, and an onBreak event
happens when the
break key is pressed. These happen regardless of which control has focus.
Fixed
Changing the background color of a control no longer changes all controls of
the same type.
Fixed
You can no longer close a window if a modal window is minimized.
Fixed
Destroying a window that has no parent will no longer stop the application,
except for the main window.
Fixed.
Edit controls and list controls can now have their backgrond color changed.
Enhanced
An window opened as a modal window will no longer allowed to have a minimize
box.
Changed
The onOpen event is now invoked before the window is opened. It used to be
invoked half way through the opening process.
