viewtopic.php?p=188063#p188063

* New color conversion functions:
- RGBTOHSL( nRGB ) --> { hue, saturation, luminence }
or RGBTOHSL( { r, g, b } )
or RGBTOHSL( R, G, B )
- HSLTORGB( { h, s, l } ) --> { R, G, B, nRGB }

* New: Class TToast implements Windows desktop notifications,
with header, footer, bitmap, settings menu, button close, and possibility of
add controls of notification.
Also, It can be used to create a standard tooltip control with the same
properties as notifications.

Please review samples\toastest.prg for a working example.

* XBROWSE:
(a) Fix: Veritcal resizing of row height with mouse at runtime
stopped working from ver.15.12. Fixed
(b) Enhancement: SetCheck() was required to be called only before the
Adjust() method of xbrowse was executed. Now SetCheck() can be called
at anytime, including runtime.
- SetCheck() also centers header.

Note: When XBrowse is created in a Window, Adjust() is called during
execution of CreateFromCode(). In case of dialogs, Adjust() method is
executed during Init of the Dialog.

(c) Enhancement: AutoFit() can be called at anytime now:
AutoFit( [aColsToFit], [lVisibleOrNumRows], [lDataOnly], [nMaxWidth] )
aColsToFit: Optional array of columns to fit.
Defaults to all columns, if called after Adjust() method
Defaults to only those columns to which nWidth is not expressly
assigned (and EDIT_LISTBOX), if called before Adjust() method.
lVisibleOrnumRows: When .T. is specified during runtime, only visible
rows are adjusted. If a number is specifed, only the first specified
of rows are adjusted.
Default is all rows. This may be slow for large disk based datas sources.
lDataOnly: Default .f. If .t. width is adjusted to fit data only and header
and footer widths are not considered.
nMaxWidth: If specified the width of any column is limited to this maximum.

(d) New data lDrawBorder (default .f.)
If set to .t., draws a single line border around the browse. Useful when
not having recordselector, headers, or scrollbars.

* New Class TArrayData:
Can be used with multi-dimentional arrays the same way as TDatabase and
TRecset.
Usage:
oData := TArrayData():New( aArrayData, aStructure )
aStructure is similar to dbf structure.
Method SetArray( aData ) can be used to set / reset array data.

- Fields can be accessed and assigned simlar to TDatabase like
oData:Salary := 2500

- All navigational methods similar to DBF and also RecordSet can be used
(eg. gotop(), gobottom(), movefirst(), movelast(), etc )

- While it is desriable to initialize with multi-dim array conforming to
the data structure provided, single dimentional and ragged arrays are
converted as multidimentional arrays of the required number of columns
initially by the class.

- Datatypes not matching with the types in the aStrcture are converted
suitably while accessing and assignment.

- Expressions like "QUANTITY * PRICE" can be used. Eg:
? oData:FieldGet( "QUANTITY * PRICE" )

- Sorting: Method SetOrder( fieldname, nil, lDescend )
- SetOrder is possible only with single fieldname.
- :SetOrder( 0 ) restores natural order. The same order at the time of
creation of the object
- oData:Sort := "SALARY DESC" also is possbile like a RecordSet.

- Filtering: Method SetFilter( <expression> )
eg: oData:SetFilter( "QUANTITY > 2000 .AND. YEAR(INVDATE) == 2016" )
oData:SetFilter( "" ) clears filter.
oData:Filter := "STATE == 'NY'" also is possible
