Version 3.2.0

The MiniGUI development team announces the availability of MiniGUI 3.2.0. All users of MiniGUI are recommended strongly to use this version for new MiniGUI apps. Please report any bugs and incompatibilities in

https://github.com/VincentWei/minigui

What's new in this version

  • Support for 64-bit platform. Note that the definitions of some types and APIs changed.
  • Compliant to the latest GCC, and eliminate all compilation warnings.

Type changes

Changes of handle types

All handle types, including GHANDLE, HWND, HDC, etc., are now defined as aliases of PVOID (typedef void* PVOID). You may need to check your code to reflect this change.

Changes of integer types.

The type of DWORD now has pointer precision. That is, the size of DWORD will be 4 bytes on 32-bit platform, and 8 bytes on 64-bit platform.

Similarly, WPARAM and LPARAM now have pointer precision.

WORD and SWORD has a half of pointer precision. The size of these two types is 2 bytes on 32-bit platform, and 4 bytes on 64-bit platform.

RGBCOLOR now is defined as an alias of DWORD32 (see below).

Note that the type of BYTE always has the size of 8-bit on both 32-bit and 64-bit platforms.

New integer types:

We introduce DWORD32 and SDWORD32 types, which have the size of 4 bytes on both 32-bit and 64-bit platforms. You should use these types when reading/writing 32-bit integers from a binary files for the portability. Of course, you can also use Uint32 or Sint32 types.

Similarly, we introduce WORD16 and SWORD16 types, which have the size of 2 bytes on both 32-bit and 64-bit platforms. You should use these types when reading/writing 16-bit integers from a binary file for the portability. Of course, you can also use Uint16 or SUint16 types.

LRESULT is defined for window callback procedure, and it has pointer precision.

LINT is a new integer type with pointer precision.

API changes

Integer macros

MAKEWPARAM: this new macro makes a WPARAM value by using four bytes. On the contrary, FIRSTBYTE, SECONDBYTE, THIRDBYTE, and FOURTH macros get the four bytes from a WPARAM or a Uint32 value.

MAKEWORD16: this new macro makes a 16-bit word by using two bytes. Meanwhile, MAKEWORD makes a 16-bit word on 32-bit platform, and a 32-bit word on 64-bit platform.

Note that MAKELONG macro always makes a DWORD integer, which has pointer precision. Meanwhile, MAKELONG32 macro makes a Uint32 integer.

Note that MakeRGB and MakeRGBA macros always make DWORD32 integers. In contract, GetRValue, GetRValue, GetBValue, GetAValue always get red, green, blue, and alpha components from a DWORD32 integer respectively.

Note that you should use (-1) instead of 0xFFFFFFFF for the invalid integer or pointer type value for good portability.

Structure and functions

The main changes in structure and functions:

  • We now use a UINT instead of an int integer for the message identifier.

  • We now use a DWORD integer for the time tick count. Meanwhile, you can create 64 timers on 64-bit platform.

  • We now use a LRESULT integer for the return value of a window callback procedure. Now it is safe to return a pointer from the callback procedure on 64-bit platform. This is a very important change, and it will break the source compatibilty of your code. You should check the source code (use gcc option -Wall) carefully.

  • We now use a LINT integer for the identifier of a timer. So you can pass a pointer as the identifier of the timer on 64-bit platform. mGNCS uses MiniGUI timer in this manner.

  • We now use a LINT integer for the identifier of a control/widget and a menu item. So you can pass a pointer as the identifier of the timer on 64-bit platform. mGNCS works in this manner.

Message

The strcuture MSG and all message-related functions changed. For example, the prototype of SendMessage changed from

int SendMessage (HWND hWnd, int nMsg, WPARAM wParam, LPARAM lParam)

to

LRESULT SendMessage (HWND hWnd, UINT nMsg, WPARAM wParam, LPARAM lParam)

IMPORTANT NOTE

For best portability, you should use FIRSTBYTE to FOURTHBYTE macros to get the bytes of a character when you extract the bytes from WPARAM parameter of a MSG_CHAR message:

MSG_CHAR
unsigned char ch_buff [4];
unsigned char ch_buff [0] = FIRSTBYTE(wParam);
unsigned char ch_buff [1] = SECONDBYTE(wParam);
unsigned char ch_buff [2] = THIRDBYTE(wParam);
unsigned char ch_buff [3] = FOURTHBYTE(wParam);
Window callback procedure

Furthermore, the structure and functions to register window class, create main window, and create dialog box changed. For example, the prototype of WNDPROC changed from

typedef int (* WNDPROC)(HWND, int, WPARAM, LPARAM)

to

typedef LRESULT (* WNDPROC)(HWND, UINT, WPARAM, LPARAM)

Therefore, the prototype of DefaultWindowProc changed from

int DefaultWindowProc (HWND hWnd, int message, WPARAM wParam, LPARAM lParam)

to

LRESULT DefaultWindowProc (HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)

All main window procedures, control class procedures, and dialog box procedures defined by your app should change the implementation to reflect the changes above.

IMPORTANT NOTE

Do not cast the result returned by a window procedure to int on 64-bit platform, unless you know what your are doing.

Notification callback procedure

The type of notification callback changes from:

typedef void (* NOTIFPROC) (HWND hwnd, int id, int nc, DWORD add_data);

to

typedef void (* NOTIFPROC) (HWND hwnd, LINT id, int nc, DWORD add_data);

IMPORTANT NOTE

If you use MSG_COMMAND message to handle the notification sent from children controls, you should make sure the identifier is small enough on 64-bit platform. Because MiniGUI packs the identifier and the notification code in the WPARAM parameter:

MSG_COMMAND
int id = LOWORD(wParam);
int code = HIWORD(wParam);
HWND hwnd = (HWND)lParam;

The code above will not work on 64-bit if you use a pointer as the identifier of the control.

Therefore, we recommend strongly that you use a NOTIFYPOROC callback to handle the notification sent from controls. To do this, please call SetNotificationCallback function to set the notification callback function.

Time and timer

The prototype of GetTickCount changed from

unsigned int GetTickCount (void)

to

DWORD GetTickCount (void);

And the prototye of TIMERPROC changed from

typedef BOOL (* TIMERPROC)(HWND, int, DWORD)

to

typedef BOOL (* TIMERPROC)(HWND, LINT, DWORD)
Miscellaneous

In addition, we correct the bad or wrong definitions of some APIs:

  • DWORD2PIXEL to DWORD2Pixel. The old one has a bad name.
  • GetWindowRendererFromName: The return type changes from const WINDOW_ELEMENT_RENDERER* to WINDOW_ELEMENT_RENDERER*. So you can overload some methods directly of a renderer.
  • GetDefaultWindowElementRenderer: The return type changes from const WINDOW_ELEMENT_RENDERER* to WINDOW_ELEMENT_RENDERER*. So you can overload some methods directly of the default renderer.

Configuration option changes

We add some new options for autoconf script (configure):

  • --with-runmode: Now you can use this option to specify the runtime mode of MiniGUI. The old enable options for runmode were removed. Note that MiniGUI-Processes now is the default runmode.

  • --enable-develmode: You should use this option to define _DEBUG macro, enable -Wall -Werror option, and enable all features of MiniGUI, if you were a MiniGUI developer.
