- IMPORTANT: Some will hate it some will love it but I found a way to move VirtualShellUtilities into the common library so TNamespace can be used without the Shell Components. It is Unicode enabled by using TntControls and the {$DEFINE TNTSUPPORT} like most other Mustangpeak libraries. CommonLibrary, EasyListview and VSTools 2.0 all must be updated and rebuild, along with VirtualShellUtilities changed to MPShellUtilities in your projects. Also a number of the strings that went with VirtualShellUtilities in VirtualResources.pas are now found in MPResources.pas so this unit may need to be added to your projects as well.

|
- Added invalidation of window for full row select.
|
|

Nov 24, 2006 Version 1.5.0 Prerelease
|
|
- WARNING WARNING WARNING: A bug was discovered in the streaming of the Collection Items (the core class for
|
|
Items, Groups and Columns). I had to fix it to make the streaming extendable in the future.. and now.
|
|
I extended TEasyColumn in the last release so that means that all designtime AND persistent streams that
|
|
contain the ELV Header information will crash on start up. The problem is the wrong stream version was written
|
|
to the stream so there is no way to identify it on read in. It will give a stream read error when it is loaded.
|
|
I can't apologize enough for this mistake, it will be a painful upgrade.
|
|
- Fixed bug in the Collection Editor that caused a random AV in the IDE if the ELV was deleted
|
|
|
|
|
|
Nov 23, 2006 Version 1.5.0 Prerelease
|
|
- OnCustomView event has been renamed to OnItemCustomView and OnGroupCustomView and OnColumnCustomView added.
|
|
this will break your DFM file sorry... but it had to be changed.
|
|
- Some internal renaming of classes, for the TEasy... prefix
|
|
- Reworked the way the default views were stored. They are no longer stored a static properties they
|
|
call the new event handlers and dynamically callback everytime they are needed
|
|
- This means the way the View property works. This should fix the issue in the last SVN update
|
|
- TEAsyColumn.AutoToggleSort has been renamed to TEAsyColumn.AutoToggleSortGlyph to more accurately reflect
|
|
what it does. It should translate to the new property in the DFM without notice
|
|
- There is a new property TEasyColumn.AutoSortOnClick. This causes the Sorter to sort the list if the
|
|
header is clicked even if the ELV.Sort.AutoSort is False.
|
|
- Added TEasyBaseTaskBand.AutoScrollPanels to allow for the scroll bars of the panels to be shown or
|
|
not used if the band is smaller then the Panel
|
|
- Fixed a bug in the Theming with the TaskPanels
|
|
- Fixed bug in NavigateItemInternal, gave an AV under special conditions
|
|
- Added default parameter to DeleteSelected
|
|
procedure DeleteSelected(SelectPrevItem: Boolean = False);
|
|
- Added:
|
|
function CanMoveDown: Boolean;
|
|
function CanMoveUp: Boolean;
|
|
function MoveDown: Boolean;
|
|
function MoveUp: Boolean;
|
|
to allow selected items to be moved up or down. Make sure AutoSort is off.
|
|
|
|
Nov 12, 2006 Version 1.5.0 Prerelease

TWideStringDynArray to TCommonWideStringDynArray
|
|
TIntegerDynArray to TCommonIntegerDynArray;
|
|
TEasyFormatEtcArray to TCommonFormatEtcArray
|
|
TEasyVAlignment to TCommonVAlignment
|
|
- Number of renamings to support the above changes
|
|
- Added new component TEasyTaskPanelBand see the TaskPanel demo.
|
|
New panels are created in the File > New > Other... and the "New" tab under "EasyListview TaskPanel"
|
|
- New demo for the TEasyTaskPanelBand
|
|
- Moved the EasyDataObject into the Common Library Package (CommonDataObject)
|

|
|

see the Overview demo.
|
|

|
|
|
Oct 8, 2006

|
|
- Added an ELV.Selection.DeleteSelected method

- Major internal change to adding/deleting items. For large data sets the speed of the control
|
|
may be significantly slower. This is because the items are reindexed for every addition
|
|
and deleting of an item for robustness under all conditions. This can be manually shutoff
|
|
with the new property ReIndexDisable. For instance:
|
|
|
|
ELV.Items.ReIndexDisable := True;
|
|
try
|
|
// Add the items here
|
|
finally
|
|
ELV.Items.ReIndexDisable := False
|
|
end
|
|
|
|
or
|
|
|
|
ELV.Groups.ReIndexDisable := True;
|
|
try

|
// Add the items here
|
|

ELV.Groups.ReIndexDisable := False

|
|
- Fixed some painting bugs in Thumbnail view.
|
|
- Added internal streaming versioning to update stream without invalidating older streams
|
|
- The Edit method now takes a column parameter. This will put different columns into edit mode in report view.

|

|
July 28, 2006
|
|
- Complete rework of the component structure, EasyListview now requires the
|
|
new MustangPeak Common Library components to be installed first.
|
|
Most issues can in compiling existing EasyListview code can be solved by replacing
|
|
any missing unit in your compile with...
|
|
|
|
uses
|
|
MPCommonUtilities, MPCommonObjects, MPShellTypes;
|
|
|
|
If you are using TWideFileStream or TWideStringList I suggest you use the Tnt Unicode package
|
|
available from
|
|
|
|
http://www.tntware.com/delphicontrols/unicode/
|
|
|
|
There is no point in me duplicating this work.
|
|
|
|
Any function used in the old VirtualUtilities or VirtualWideStrings that ended with a "W" is now
|
|
like the Tnt functions and begin with "Wide"
|
|
|
|
FileExistsW is now WideFileExists
|
|
ect...
|
|
DirExistsW is an exception it maps to WideDirectoryExists
|
|
|
|
If any object that use to be called TVirtualXXXXX or TEasyXXXX it is likely now
|
|
called TCommonXXXXX and in the MPCommonObjects.pas file of the Mustangpeak
|
|
Common Library Package.
|
|
|
|
Other issues that may be noticable at design time are:
|
|
|
|
An invalid stream read on a MouseButton type. This was a misspelling so just
|
|
ignore it. You may have to reset the mouse buttons that will allow a drag
|
|
select for nondefault buttons (left, right).
|
|
|
|
TEasyKeyStates => TCommonKeyStates
|
|
TEasyDropEffects => TCommonDropEffects
|
|
TEasyDropEffect => TCommonDropEffect
|
|
|
|
edeCopy, edeMove, edeLink => cdeCopy, cdeMove, cdeLink
|
|
edeNone, ..... edeScroll => cdeNone, ..... cdeScroll
|
|
|
|
THDrop => TCommonHDrop
|
|
|
|
TEasyMouseButton => TCommonMouseButton
|
|
|
|
|
|
May 28, 2006
|
|
- Added ELV.paintInfoItem.ShowBorder to not show a border
|
|
on views with Borders.
|
|
- Added TEasyAlphaBlender.BasicBlend with the same parameters
|
|
as the old blend method.
|
|
|
|
May 27, 2006
|
|
- Added OnItemSelectionsChanged to notify when item selection
|
|
has changed in volumn. OnItemSelectionChange is fired for
|
|
every item that changes selection state. This new event
|
|
only fires once when 1 or a block of items has changed
|
|
selection in one action (SelectAll for instance), Mantis #87
|
|
- Finished implementing the Hot-Tracking.
|
|
- TaskBand Hot-tracking now works as in Explorer, Mantis #83
|
|
|
|
May 26, 2006
|
|

|
scrolling options. See the ThumbScroller Demo.

|
|
easily hide unwanted properties.

|
|
|
May 22, 2006
|
|
- Fixed bug when deleting items and the scrollbar was not at 0.
|
|

May 18, 2006
|
|
- Added to Tcolumn
|
|
- property AutoSizeOnDblClk;
|
|
- property AutoSpring;
|
|
AutoSizeOnDblClk resized the column to fit all captions if doubled clicks in
|
|
resize area of the header.
|
|
AutoSpring works like in VT. The columns try to stay in the same proportion
|
|
to other columns as the window is resized.
|
|
