* contrib/gtwvw/gtwvw.c
! WM_HSCROLL and WM_VSCROLL should be controlled by bTopMost || s_bAllowNonTop,
not by hb_wvw_gtAcceptingInput(). This may cause problem if WVW_SETFOCUS interferes.
Fixed.
! wvw_ebcreate() :: do NOT use ES_OEMCONVERT by default
2007-05-29 09:45 UTC+0700 Budyanto Dj. <budyanto@centrin.net.id>
* contrib/gtwvw/samples/wvwtest9.prg

Note that SETKEY is still in effect during editbox editing,
thus this editbox is expected to be able to replace standard @..GET
(or memoline() if it is multiline editbox).
I have also tested that a proper editbox callback can be written to
handle masked input as in @...GET..PICTURE..

Notes on WVW_DRAWIMAGE()
/*
(1) Transparency
if bTransparent is .t., top-left pixel is used as the transparent color,
(2) Image dimension
if nBottom is NIL, then image height will be proportional to original image.
if nRight is NIL, then image width will be proportional to original image.
if nBottom and nRight are BOTH NIL then original image dimension is used
(3) Caching
This function will now CACHE the image.

* contrib/wvtgui/wvtcore.c
! Fixed resources leak in wv*_drawline() and wv*_drawoutline().
Reported and tested by Lajos Mihalffy on gtwvw.
2005-10-31 23:55 UTC+0700 Budyanto Dj. <budyanto@centrin.net.id>
* contrib/gtwvw/gtwvw.c
* wvw_pbcreate() now support bitmap on buttons.
! wvw_pbsetfocus() and wvw_cbsetfocus() was always returning .f., fixed.
2005-10-19 18:00 UTC+0700 Budyanto Dj. <budyanto@centrin.net.id>
* contrib/gtwvw/hbgtwvw.h

! Typo fixed in gt_VertLine() causing incorrect dispbox() in MainCoord mode
* contrib/gtwvw/doc/whatsnew.txt
* change recorded
2005-10-06 09:20 UTC+0700 Budyanto Dj. <budyanto@centrin.net.id>
* contrib/gtwvw/hbgtwvw.h
* contrib/gtwvw/gtwvw.c
! Fixed all callback calls to use hb_vmPushState()/hb_vmPopState().
* Applying the proper codeblock handling, as suggested by Przemek.
As a side effect, I rename GLOBAL_DATA member cbFunc/cbFuncModal
into pcbFunc/pcbFuncModal. They now store pointer to codeblock,
not the codeblock itself.
The same thing with CONTROL_DATA's hiCodeBlock --> phiCodeBlock.
=========================================================================
2005-08-30 23:45 UTC+0700 Budyanto Dj. <budyanto@centrin.net.id> :: BEGIN
=============
MAXIMIZE MODE
=============
Gtwvw now allows its`windows to be in MAXIMIZED mode.
Please notice, however, that there are some things need to be addressed when
implementing this mode.
To implement this mode, app should have a special callback function WVW_SIZE.
This function is called by Gtwvw AFTER a window size is changed, as when the
window is maximized or restored.
See the sample prog doc/maximize.prg on how to apply a simple WVW_SIZE function.
Some new/modified supporting functions in this area of interest:
+ WVW_UNREACHEDBR( [nWinNum], [nBottomPixels], [nRightPixels] )
get unreached pixels below maxrow() to nBottomPixels
and on the right of maxcols() to nRightPixels.
+ WVW_MAXMAXROW() : returns maximum possible maxrow()
+ WVW_MAXMAXCOL() : returns maximum possible maxcol()
* WVW_MAXIMIZE()
! This function now really maximizes the window, provided
user has the WVW_SIZE function.
(This is different with gtwvt's WVT_MAXIMIZE which really does a RESTORE).
+ WVW_RESTORE()
* Restores a window
+ WVW_ENABLEMAXIMIZE()
* Enables the Maximize/Restore button.
==================
WINDOW POSITIONING
==================
Some new functions regarding window positioning:
+ WVW_SETDEFCENTREWINDOW() to change default CentreWindow setting.
CentreWindow==.t. will cause subsequent opened windows be centered vertically and horizontally.
+ WVW_SETDEFHCENTREWINDOW() to change default HCentreWindow setting.
HCentreWindow==.t. will cause subsequent opened windows be centered horizontally.
+ WVW_SETDEFVCENTREWINDOW() to change default VCentreWindow setting.
VCentreWindow==.t. will cause subsequent opened windows be centered vertically.
* WVW_XREPOSWINDOW() now has an optional param lAnchored (default is .t.).
If it's .f. then subwindows will be positioned according to each CentreWindow setting.
/*
DefCentreWindow, DefHCentreWindow, DefVCentreWindow are default setting used when opening a new subwindow.
if DefCentreWindow == .t.
newly open subwindow will be placed centered both vertically and horizontally in respect to Main Window
else
if DefHCentreWindow == .t.
newly open subwindow will be horizontally centered in respect to Main Window
endif
if DefVCentreWindow == .t.
newly open subwindow will be vertically centered in respect to Main Window
endif
endif
*/
=========
SCROLLBAR
=========
Some changes regarding scrollbar:
! fix problem of missed WM_LBUTTONUP causing "sticky" scrollbar
! if "sticky" scrollbar still occurs, WM_CHAR will stop it
! etc.
+ WVW_XBinfo( [nWinNum], XBid )
return an array {nMin, nMax, nPageSize, nPos, nTrackPos } of scrollbar XBid
return an empty array {} if invalid parameter passed.
* WM_RBUTTON* on scrollbar is now disabled.
========
COMBOBOX
========
* all arrow keys are now passed to parent window,
regardless of Ctrl, Alt, and Shift states.
(only in WVW_CB_KBD_CLIPPER)
=============
MISCELLANEOUS
=============
* WVW_DRAWLABELOBJ() added aOffset optional parm
* gtWndProc handles unreached area "better"
will repaint it on maxcol()/maxrow() event
* WM_CLOSE on Main Window is now followed by K_ESC,
thus in a case where SETCANCEL() is .f. an app can still handle this event.

* use CF_OEMTEXT parameter for clipboard functions for OEM charsets
by Pavel Tsarenko.
2004/12/23:
* gtwvw.c
! HB_FUNC( WVW_SETICON ) should pass hb_parc(3) instead of hb_parcx(3) to
hb_wvw_gtSetWindowIcon() in order to allow proper NULL checking there.
(hb_parcx(3) never returns NULL, even if param 3 is NIL.
2004/12/22:
Combobox (dropdown listbox) is introduced.
This feature is accessible throug the WVW_CB* functions.
(See IMPORTANT NOTES below regarding WVW_CBADDSTRING() and WVW_CBSETCURSEL())
Side Effects:
* WVW_ID_BASE_PUSHBUTTON is now 64000 (was 65000).
It means we may not have Menu Id >= 64000 now.
New .PRG callable Functions: (combobox functions):
+ WVW_CBcreate( [nWinNum], nTop, nLeft, nWidth, aText, bBlock, nListLines, ;
nReserved, nKbdType, aOffset)
+ WVW_CBdestroy( [nWinNum], nCBid )
+ WVW_CBsetFocus( [nWinNum], nComboId )
+ WVW_CBisFocused( [nWinNum], nComboId )
+ WVW_CBenable( [nWinNum], nComboId, [lEnable] )
+ WVW_CBsetcodeblock( [nWinNum], nCBid, bBlock )
+ WVW_CBSetFont([nWinNum], cFontFace, nHeight, nWidth, nWeight, nQUality,;
lItalic, lUnderline, lStrikeout
+ WVW_CBsetIndex( [nWinNum], nCBid, nIndex )
+ WVW_CBgetIndex( [nWinNum], nCBid )
+ WVW_CBfindString( [nWinNum], nCBid, cString )
+ WVW_CBGetCurText( [nWinNum], nCBid )
IMPORTANT NOTICE:
* WVW_CBADDSTRING() and WVW_CBSETCURSEL() are NOT part of the above WVW_CB* functions family.
These two functions are adopted from gtwvt (long time ago), and I keep these names to
keep gtwvw's "historical links" to gtwvt unbroken.
TODO:
Create a sample of how to integrate combobox into regular GET system.

/* WARNING: Your program may need to change! */
/* */
/*-------------------------------------------------------------------*/
-------------------
WVW_DrawRoundRect()
-------------------
If you use this function, you may need to make a change:
Previously:
Wvw_DrawRoundRect( nWinNum, nTop, nLeft, nBottom, nRight, ;
nRoundHeight, nRoundWidth )
Now:
Wvw_DrawRoundRect( nWinNum, nTop, nLeft, nBottom, nRight, ;
aOffset, ; <-- new optional parm following GTWVT's
nRoundHeight, nRoundWidth )
----------------------------------------
Toolbar, Menu Command Id vs Push Buttons
----------------------------------------
This release introduces native push buttons. Internally pushbuttons use
command id 65000 and above. Therefore, do NOT use menu/toolbar commands
with id >= 65000.
You are further recommended not to use high numbered id (say >= 40000),
because future GTWVW may need that for its internal use.
-------------------------------
WVW_SetPen() and WVW_SetBrush()
-------------------------------
First parameter of WVW_SetPen() and WVW_SetBrush() are nWinNum.
This is still true in current release. However, it is now ignored,
because now the same PENs and BRUSHes are now used by all window.
There is no more specific PENs and BRUSHes for specific window.
I have to do this change, because previous release of GTWVW causes
GDI leak because of this PENs and BRUSHes stuff...
/*-------------------------------------------------------------------*/
/* */
/* New Native Controls */
/* */
/*-------------------------------------------------------------------*/
------------
Push Buttons
------------
You can now create pushbutton very easily. Simply define where do you
want it to sit, and what action do you want it to do when it's clicked
by means of a codeblock.
In previous version, we had to use WVWMOUSE.PRG to simulate pushbuttons
using wvw_DrawBoxRaised(). We also had to handle 'OnMouseHover', 'OnMouseOut',
'OnPressed', etc, to simulate the pressed/released state of the button.
By using native push buttons, we don't have to worry about all that anymore.
Windows will take care about it.
If we are using Windows XP style, pushbuttons will automatically behave
as they should in Windows XP: round shaped, hot when mouse hovers, etc.
Push button functions are prefixed with wvw_pb*, for example:
wvw_pbCreate()
wvw_pbDestroy()
wvw_pbSetFont()
etc
------------
Progress Bar
------------
Progress Bar is one of the simplest controls. Gtwvw now uses native
progress bar. It is a preferred method instead of the simulated one
using wvw_DrawProgressBar().
Progress bar functions are prefixed with wvw_pg*, for example:
wvw_pgCreate()
wvw_pgDestroy()
wvw_pgSetRange()
wvw_pgSetPos()
etc.
/*-------------------------------------------------------------------*/
/* */
/* New Callback Functions */
/* */
/*-------------------------------------------------------------------*/
----------------
WVW_INPUTFOCUS()
----------------
If exists, this function is called by GTWVW whenever input occurs on
non topmost window. (Currently GTWVW allows only topmost window, that
is the last window opened, to accept input.)
For example, assume your program is displaying Main Window and another
window. If at this point the user click the Main Window and select
some menu item, GTWVW will reject to handle this event because Main
Window is not currently topmost.
Typically GTWVW will produce an asterisk sound and flash the topmost
window to tell user which window is expecting input.
In current GTWVW, prior to do that GTWVW will call WVW_INPUTFOCUS()
function, if exists, and inspect its return value. If it returns .t.,
then GTWVW do nothing, assuming the event has been handled properly
by WVW_INPUTFOCUS().
If no WVW_INPUTFOCUS() exists, or if it returns .f., GTWVW will do
the usual response: asterisk sound and flashing window.
See INPFOCUS.PRG sample program demonstrating this feature.
/*-------------------------------------------------------------------*/

Windows 98's DC
---------------
Thanks to Anatole Kolotovkin who reported this bug in Win98, where
GDI objects are display incorrectly after opening some 5 windows or
more. (In WinXP this bug doesn't occur.)
This bug has now been fixed in current release.
--------
GDI Leak
--------
Some GDI objects (PENs and BRUSHes) mysteriously persist, even after
the objects are successfully deleted.
This has now been fixed. But as a side effect, GTWVW does not support
specific window's PENs and BRUSHes anymore. PENs and BRUSHes are now
application-wide.
-------------------------------
Other bugfixes and enhancements
-------------------------------
There are also many other minor bugfixes and enhancements.
Some of the enhancements are additional aOffset parameter to
WVW_Draw* functions.

APPLIED CHANGES ADOPTED FROM GTWVT:
-----------------------------------
+ Support Modeless Dialog (attached to Main Window).
This is adopted from original work of Pritpal Bedi on GTWVT.
! Bugfix in Clipboard function, copied from the fix by Pritpal Bedi on GTWVT.
+ some new GTI_ functions, adopted from Lorenzo Fiorini's work on GTWVT.
+ gt_gfxPrimitive() function, adopted from original work of Mauricio Abre
on GTWVT
! Improvement in internal point to char conversion, adopted from
Peter Rees' work on GTWVT
* If app has ANNOUNCE HB_NOSTARTUPWINDOW Main Window is not displayed
until after the app ready and call WVW_SHOWWINDOW(0).
This may result in a better visual effect as opposed to watching
the window resized or prepared during window initialization.
(Some app may also choose to never show the Main Window.)
This is adopted from original idea of Pritpal Bedi on GTWVT.
+ New Function WVW_NoStartupSubWindow() to get similar feature on subwindows.
If this feature is used, app must call WVW_ShowWindow([nWinNum], 1)
or simply WVW_ShowWindow([nWinNum]) to display the previously opened
window.
* Some castings and optimizations.
* Some changes in some EXPORTed C functions.
(All .PRG / HB_FUNC functions are not affected)
* aOffset parameter to more primitive GUI drawing functions
(following the changes on GTWVT by Pritpal Bedi)
*****************************************************************
WARNING!!!
WVW_DRAWROUNDRECT() parameter is shifted because of insertion of
a new parameter aOffset.
*****************************************************************
* Some changes to Tooltip functions
(adopted from Pritpal Bedi's work on GTWVT)
+ New .PRG / HB_FUNC functions: (adopted from Pritpal Bedi's on GTWVT)
+ HB_FUNC( WVW_UPDATEWINDOW )
+ HB_FUNC( WVW_DRAWCOLORRECT ) (similar to WVW_FillRectangle)
+ DlgModeless functions
+ many WIN_* functions, general window API wrapper functions
- Removed .PRG / HB_FUNC functions:
- WVW_DeleteObject()
(following GTWVT. Use WIN_DeleteObject() instead)
-----------------------------------------------
CHANGES ON GTWVT THAT ARE NOT ADOPTED ON GTWVW:
