Release 3.3.1

• Fixed a bug regarding the missing null terminator in List items when the string value passed to MSListAddItem() or MSListAddElement() is larger than the list's width. The bug occurs as you get the item text value.
• Drawing fixes for buttons and TabbedForm.
• MSBLSetHead() now removes the List head if the passed 'text' argument is a NULL pointer.
• MSBLGetHead() now returns an empty string on return when there's no head in the List.
• Fixed a bug in setting the shadow for Image Radio and Toggle Buttons

Release 3.3.0

• Child spacing in SHELL object is reset to 3 pixels. This value can be changed via the MFormSetSpacing() function used on the SHELL object.
• MObjectSetPosition(), MObjectSetX() and MObjectSetY() on composite widgets now affect the position of their main container.
• MObjectResize() now correctly handles the setting of a single dimension, for example:
  MObjectResize(obj, 128, -1);
  will cause obj's width to be set to 128 while obj's height will be set to obj's default.
• New function:
  void MPagedFormSetNPages(OBJECT *form, int np);
  When the number of pages is reduced any child object contained in such pages is destroyed.
• Fixed some bugs in changing the color of Toggle and Radio buttons.
• Fixed a bug in drawing the Tab buttons of a TabbedForm.
• New functions to disable/enable user input in EDIT objects:
  void MEditDisableEditing(MOBJECT edit);
  void MEditEnableEditing(MOBJECT edit);
  
  The disabled status is useful in OptionEdit and SpinEdit objects if you need to prevent direct user input while allowing the selection of program controlled values (via the option list or the spin callback).
• Directory list in FileSelection dialog is now ordered without regard to case.
• Speed search in List objects now correctly handles the user specified sorting callback. Case unsensitive search now works, provided that the user sets stricmp as the sort callback. Function stricmp is defined as a macro in file mguidefs.h in case the programming environment does not provide it as a standard function (this applies to GCC).
• New OptionEdit function to set a callback on list item selection:
  void MOptionEditSetListCallback(MOBJECT obj, LIST_ACT_CB cb, void *data);
• New function to enable item motion in a List object via
  void MSListEnableItemMotion(MOBJECT p);
  Further utility functions:
  void MSListDisableMultiSel(MOBJECT obj);
  void MSListDisableItemMotion(MOBJECT obj);
• New MessageDialog functions:
  void MSetMessageDialogFgRGB(int r, int g, int b);
  void MGetMessageDialogFgRGB(int *pr, int *pg, int *pb);
  void MSetMessageDialogFonts(MTFont text_font, MTFont buttons_font);
  void MGetMessageDialogFonts(MTFont *text_font, MTFont *buttons_font);
• Disk errors catching now works under Watcom DOS too when the MFileSelection() function navigates available disk drives.
• New DOS utility functions to catch disk errors:
  
  void MClearDiskError(void);
  Resets the error. Must be called before the call to a DOS function that may generate a disk error.
  
  int MGetDiskError(int *disk, int *code);
  Returns != 0 if a catched error if found.
  On return *disk will contain an index for the failing drive
  
  
  • 0: A
  • 1: B
  • 2: C
    ...
    
    *code will return one of the following codes:
    
    
  • 0: write protected disk
  • 2: drive not ready
  • 12: unformatted disk
  
  int MShouldRetryDueToDiskError(void);
  Returns != 0 if a retryable error is found and the user chooses the retry button in a prompted dialog window.
  
  These functions are used internally by MFileSelection() function to catch and handle disk errors prompting the user to recover a 'drive not ready' condition.
  You can use these functions in your own DOS MGui code to handle disk error conditions.
  Example:
  

    vFindfirst(char *path, struct find_t *ffb, int attr)
    {
  	int ret;
  
  	do {
  		MClearDiskError();
  		ret = _dos_findfirst(path, attr, ffb);
  	} while (MShouldRetryDueToDiskError());
  	return ret;
    }
  
  

Release 3.2.2

• Fixed crash problem occurring when an ImageRButton object is created using an unavailable image file as the image to be drawn in the normal state.
• Added a new option in the resource file for console based MGUI programs (that is DOS or Linux SVGA/GRX). The option name is 'centeredBitmap' and it can be defined in the 'Desktop' section to specify whether the desktop image should be drawn centered or tiled (default). Allowed values are boolean '0' and '1'.
  Example:
  
  [Desktop]
  
  background = 110, 130, 100
  bitmap = tile9.bmp
  centerBitmap = 1

Release 3.2.1

• Fixed a bug regarding the unwanted foreground color reset to Black for transparent objects (as Labels) when the background color of the container object is changed. This bug was introduced in release 3.0.0.
• Fixed a bug regarding the lack of focus setting when the OptionEdit list is open.
• Making an object transparent no longer resets its foreground color to the parent's foreground color.
• Fixed a bug in drawing the scrollbar shadow (introduced in release 3.2.0).

Release 3.2.0

• Fixed a bug in drawing the horizontal scrollbar in the ScrolledEdit object. This bug was introduced in release 3.0.0.
• Fixed a bug in the C++ method:
  CmShell::setWMCloseCallback(CmCallback *pp, VOID_CB ff);
  It only worked when the 'pp' argument was a pointer to an object of a class derived from CmShell.
• Font loading support is now extended to ALL DOS platforms (including DOS BGI).
• Font definition in the resource file for ALL DOS platforms is now identical to Windows (for a subset of supported font families). So the MGUI configuration file under ALL DOS platforms is the same used for Windows: mgui.ini

The program's resource file name also moves the extension to .ini
• A new environment variable MFONTDIR selects the directory containing MFN font files for DOS versions of MGUI. By default this directory is located in: \mgui\sys\fonts\cp1252 (for western language PCs).
• Font enumerating is now supported under ALL platforms via the new functions:
 
char *MGetFirstFontFamily(void);
char *MGetNextFontFamily(void);

Call the first function to get the first available font family, then iteratively call the second one to get successive font families. MGetNextFontFamily() will return a NULL pointer when no more font families are available.

Release 3.1.0

• C++ Library archive is now more fragmented to minimize unuseful code linking. This allows you to get smaller exe if your program uses a small portion of the MGUI API.
• The Character Browser dialog now must be enabled via a function call at program startup:
void MEnableCharBrowser(void);

Release 3.0.1

• A new macro named DEF_POSITION allows to specify a default value in X or Y coordinate when realizing a SHELL using MShellRealizeXY() and MShellRealizeXYWH().

The dafault value causes the window to be centered in the corresponding direction.
Another macro named DEF_SIZE allows to specify a default size for the width or height when realizing a SHELL using MShellRealizeXYWH().
Of course, calling
MShellRealizeXYWH(shell, DEF_POSITION, DEF_POSITION, DEF_SIZE, DEF_SIZE);
has the same effect as calling:
    MShellRealize(shell);
 
• Fixed a bug occurring when a SrcolledFormattedText object is made transparent.

 
• New functions for the FormattedTextObject:

    void MFormattedTextSetMargin(MOBJECT obj, int w_m, int h_m);
    void MFormattedTextSetHSpacing(MOBJECT obj, int h_s);
 

Release 3.0.0

• New Container Object: PosForm

This new container does NOT automatically arrange the position and size of its children. You have to attach each child object using the new function:
void MObjectSetPosition(MOBJECT obj, int x, int y);
  or:
void MObjectSetX(MOBJECT obj, int x);
void MObjectSetY(MOBJECT obj, int y);

  New PosForm creation functions available:

  MOBJECT MCreatePosForm(MOBJECT parent);
  MOBJECT MCreatePagedPosForm(MOBJECT parent, int npage);
  MOBJECT MCreateTabbedPosForm(MOBJECT parent, int npage, MTFont f);
  MOBJECT MCreateScrolledPosForm(MOBJECT parent, int clip_w, int clip_h);
  MOBJECT MCreateClippedPosForm(MOBJECT parent, int clip_w, int clip_h);

  The following functions:

  MOBJECT MCreateScrolledForm(MOBJECT parent, int clip_w, int clip_h);
  MOBJECT MCreateClippedForm(MOBJECT parent, int clip_w, int clip_h);

  are obsoleted by the following:

  MOBJECT MCreateScrolledRowForm(MOBJECT parent, int clip_w, int clip_h);
  MOBJECT MCreateScrolledColForm(MOBJECT parent, int clip_w, int clip_h);
  MOBJECT MCreateClippedRowForm(MOBJECT parent, int clip_w, int clip_h);
  MOBJECT MCreateClippedColForm(MOBJECT parent, int clip_w, int clip_h);

  Obsolete function prototypes are available via the macro switch "OLD_MGUI"
 

• Support added for transparent background in MGUI objects.

By default, LABEL and RADIO&TOGGLE buttons are now transparent.
The transparency level is an unsigned 8 bit value between 0 and 255. A value of 0 means no transparency, while a value of 255 means completely transparent.
WARNING:
    Transparency levels other than 0 and 255 are currently not supported.
    They are reserved for future use as 'alpha channel' transparency.
New functions:
  void MObjectSetTransparency(MOBJECT obj, CARD8 level);
  CARD8 MObjectGetTransparency(MOBJECT obj);

Using MObjectSetColor() or MObjectSetBackgroundRGB() on a transparent object will make solid (transparency level = 0).
 

• Support added for background image on MGUI objects.

Background images are also supported in the Desktop of console mode MGUI programs (DOS and Linux svgalib/GRX).
New funcrions:
  void MObjectSetBackgroundImage(MOBJECT obj, MIMAGE img, int mode);
  void MObjectSetBackgroundImageFile(MOBJECT obj, const char *fname, int mode);
  MIMAGE MObjectGetBackgroundImage(MOBJECT obj);
The value of 'mode' specifies the way the image is drawn. It can be one of the following values:
 
•  BI_TILED
•  BI_CENTERED
•  BI_SIZE_FORCING


 Last setting will cause the object to acquire the image size.
 

• A new utility function allows creating a mask for an image by using the color of the pixel at ('x','y') as the mask color.

This function works well on both colormapped and TrueColor images.
 
MIMAGE MCreateImageMaskByPixel(MIMAGE img, int x, int y);
• Support for handling object geometry has been improved:

Old functions:

 int  MObjectX(MOBJECT obj);

 int  MObjectHeight(MOBJECT obj);

are obsoleted by:

 int  MObjectGetX(MOBJECT obj);
 int  MObjectGetY(MOBJECT obj);
 int  MObjectGetWidth(MOBJECT obj);
 int  MObjectGetHeight(MOBJECT obj);

Obsolete function prototypes are available via the macro switch "OLD_MGUI"

  New functions:

MOBJECTMCreateScrolledFormattedText(MOBJECT par, const char *text, int clip_w, int clip_h, MTFont f);

Release 2.7.2

• The MImageMerge function now works and has new prototype:

 void MImageMerge(MIMAGE dst, MIMAGE src, int xo, int yo, int transparent);
Image 'src' is copied over image 'dst' starting at offset 'xo','yo'.
Pixels in 'src' having a color index equal to 'transparent' are not copied.
This function only works with colormapped images having the same depth (2, 16 or 256 colors).

• Ctrl+F5 Hiragana (full width)
• Fixed a bug in the OptionEdit object occurring when items inserted in the list are clipped due to a different clip lenght between the EditField and the items in the list.

Text picked from the item list was one byte longer than the text actually put in the EditField. This caused the wrong condition that an item picked from the list could be NOT FOUND in the list!
 

Release 2.6.3

• Fixed a bug in the CmStatusBar object's setWidth() method inherithed from CmObject class.

MStatusBarSetWidth() is obsoleted by MObjectSetWidth() which now works correctly on StatusBar object too. For backward compatibility purpose, MStatusBarSetWidth is still supported as a #define redirecting the call to MObjectSetWidth().
 
• The limit to 25,600 lines allowed in the ScrolledFile object has been removed. Very large files can now be viewed correctly.

 

Release 2.6.2

• Fixed a bug in the ScrolledForm redrawing method after a resize in one of its children.
• The unsensitive state is now displayed  for LABEL too (as for buttons).
• The SCROLLBAR  object, if used out of ScrolledForm and Lists, now handles key events (arrow keys, home, end) to change its value.

Focus switching policy has been revised to better conform to standard GUI environments. A new resource is available for getting the old behavior. Add the following in you mgui or application resource file if you want to use the old policy:

 [Focus]

Release 1.8.0

• Added support for mouse cursor assigning to Objects
MTCursor MCreateCursor(MIMAGE bits, int xs, int ys);
bits is the image (colormapped) describing the cursor. black will be used as color for index 0 and white for index 1. All pixels in the image with color index other than 0 and 1 will not be part of the cursor. mask is a 1 plane image used to mask the image bits. BEWARE: currently does'nt work in Windows.
void MObjectSetCursor(MOBJECT obj, MTCursor cursor);
• Added support for popup or label help when the mouse enters the Object window
void MObjectSetPopupHelp(MOBJECT obj, char *str, int delay, int duration);
The text in the string 'str' will appear in a popup window when the mouse pointer enters the Object 'obj'.
'delay' specifies the time in millisecond to wait before opening the popup window when the cursor stops into the Object. Valid range is 0 - 32000. Default (delay < 0) is 500.
'duration' specifies the maximun time the popup stays open (in msec). Valid range is 1000 - 32000. Default (delay < 1000) is 5000.
void MObjectSetLabelHelp(MOBJECT obj, char *str, MOBJECT label);

MObjectSetDestroyCallback()
are replaced by
MObjectAddEventNotifyCallback()
MObjectAddDestroyCallback()
Macros are however activated in mgui.h (under #ifdef OLD_MGUI) for backwards compatibility.

"o" selects the 'Open' item

Release 1.6.3

• Mouse events catched with the EventNotify callback now correctly report x and y members as relative to the Object, when it's a SHELL.
• Added function MSListSetSelectionCallback() which sets a callback invoked when:
- a mouse button press occurs in the list
- the focused item changes due to a Arrow/Page/Home/End key press.
- the Ins key toggles the selection status of an item in the MultiSelection List
- deleting an item from the list the focused item changes (position or content)
- the focused item is changed via MSListChangeElement() and MSListChangeItem().
The structure reported as second argument by the callback is type (LIST_SEL *), which includes all fields in LIST_ACT and adds the field 'pe'. This field points to the Event that causes the callback calling. When the callback is called due to item deletion or modification, the 'pe' field is NULL. Both KeyEvent and MouseEvent include the 'state' field which contains a bit mask of the modifier keys state: (AltMask, ShiftMask, ControlMask). For MouseEvent only, the 'state' field includes mouse button mask (Button1Mask, Button2Mask and Button3Mask). The 'pos' field is -1 when the list becomes empty.
• Added function MGetKeyboardState() which returns a bitmask containing the possible OR-ed values: AltMask, ShiftMask, ControlMask.
