INTRODUCTION

MiniGUI is a mature cross-platform windowing system and a GUI (Graphics User Interface) support system for embedded systems and smart IoT devices. This is the version 3.2.x of MiniGUI maintained by WEI Yongming (Vincent Wei, https://github.com/VincentWei).

MiniGUI is released under GPLv3 and the dual-licensing applies to commercial use.

MiniGUI aims to provide a fast, stable, full-featured, and cross-platform windowing and GUI support system, which is especially fit for embedded systems or smart IoT devices based-on Linux/uClinux, eCos, and other traditional RTOSes, such as VxWorks, ThreadX, Nucleus, pSOS, uC/OS-II, and OSE.

This is the MiniGUI core source tree, which provides windowing and graphics interfaces as well as a lot of standard controls (tookit).

Besides MiniGUI core, FMSoft also provides some components for the developers to develop app much easier:

  • mGUtils: A MiniGUI component which contains miscellaneous utilities like ColorSelectionDialogBox, FileOpenDialogBox, and so on.

  • mGPlus: A MiniGUI component which provides support for advanced graphics functions like path, gradient, anti-aliase stretch, and color combination.

  • mGEff: mGEff provides an animation framework for MiniGUI app. It also provides some popular UI/UE special effects.

  • mGNCS: This component provides a new control set for MiniGUI app. By using mGNCS, you can use miniStudio to develop MiniGUI app in WYSIWYG way.

  • mGNCS4Touch: This component provides some new controls, which are compliant to the new control API spec of mGNCS, for devices with a touch screen.

There are also some legacy MiniGUI components. We will not maintain these components for MiniGUI core v3.2:

  • mGi: An input method component for MiniGUI. This component provides some typical input methods (such as softkey, hand-writing, and predict text input for mobile phone) for MiniGUI apps.

  • mGp: A printing component for MiniGUI. By using mGp, you can print out the graphics created by MiniGUI app to general-purpose printers.

  • mG3d: A simple three-dimension component for MiniGUI. This component provides a simple 3D API for app. You can use mG3d to create simple 3D UI.

MiniGUI is a free software project. In December 1998, the initiator of FMSoft, Wei Yongming, began to develop MiniGUI under the GNU General Public License (GPL). In September 2002, the core developers of MiniGUI founded FMSoft and started the commercial marketing with the free software. By now, FMSoft still continues to release MiniGUI as a free software project.

You can download the source code tarball of MiniGUI and the dependent libraries from the download zone of the site:

http://www.minigui.com

FMSoft also releases some open source apps for MiniGUI on the site above, for examples:

  • mDolphin, licensed under Apache 2.0, is a full-featured WEB/WAP browser, which is developed based on the open source browser core WebKit and uses MiniGUI as its underlying graphics support system.

  • mGallery, licensed under Apache 2.0, intends to provide a total solution for PMP (Portable Multimedia Player), which uses MiniGUI as the graphics platform.

  • mSpider, licensed under GPL 3.0, intends to provide a light-weight MiniGUI-based web browser (HTML 3.2 and part JavaScript)

  • mEagle, licensed under GPL 3.0, is an embedded GIS development platform which addresses the needs of map browse, query, analysis, etc

FMSoft had created the public repositories for MiniGUI core, MiniGUI components, and other open source apps on GitHub. You can visit them on:

https://github.com/VincentWei

FMSoft also releases miniStudio, which is a WYSIWYG IDE for MiniGUI, as a shareware. You can also download it from the official site of MiniGUI.

A BRIEF BUILDING INSTRUCTION

This instruction assumes that you are using Ubuntu Linux.

Prerequisites

You can run apt install <package_name> to install the software on Ubuntu Linux.

  • Building tools:
    • autoconf
  • Dependent libraries (all are optional):
    • libjpeg64-dev
    • libpng12-dev
    • libfreetype6-dev

Building

MiniGUI core uses GNU autoconf/automake scripts to configure and build the project.

Run

$ ./configure; make; sudo make install

to configure, make, and install the headers and the libraries. If there is not configure file, please run

$ ./autogen.sh

to generate the script.

MiniGUI core also provides some configuration options to customize the features. For more information, please run

$ ./configure --help

NEW FEATURES IN VERSION 3.2.x

We introduce some new features in MiniGUI Version 3.2.x:

  • The support for 64-bit platform. Note that some APIs have changed to support 64-bit platform. For more information, please refer to RELEASE-NOTES.md file.

Because of the changes of some APIs, we recommended strongly that you use this version for new projects.

THE RUNTIME MODES OF MINIGUI

You can configure and compile MiniGUI as one of three runtime modes:

  • 'MiniGUI-Threads': A program running on MiniGUI-Threads can create multiple cascaded windows in different threads, and all the windows belong to a single process. MiniGUI-Threads is fit for some real-time systems on Linux/uClinux, eCos, uC/OS-II, VxWorks, pSOS, ThreadX, and OSE.

  • 'MiniGUI-Processes': A program running on MiniGUI-Processes is an independent process, which can also create multiple windows. MiniGUI-Processes is fit for some complex embedded systems, such as PDAs, Thin-Clients or STBs. This mode is only useful for full-featured UNIX-like operating systems, like Linux.

  • 'MiniGUI-Standalone': A single process version of MiniGUI. This mode is useful for some small systems, like uClinux or RTOSes.

The original MiniGUI (version 1.0) run in MiniGUI-Threads mode. It is based on POSIX-compliant thread library. And this thread-based architecture of MiniGUI is very fit for most traditional embedded operating systems, such as eCos, uC/OS-II, and VxWorks. However, if you use embedded Linux, the architecture like X Window will have better stability and scalability, because of the independent memory address space of every process.

Since version 2.0, we provides a new runtime mode called MiniGUI-Processes. You can use MiniGUI-Processes to run more than one MiniGUI-based program in the form of UNIX process at the same time. MiniGUI-Processes is a full-featured multi-process version of original MiniGUI -- You can run a program based on MiniGUI-Processes from a program called 'mginit'. Just like X Window, the former process is called a client, and the latter the server.

Clients connect to the server via UNIX domain socket, and the server receives and responses requests from clients. The server provides shared resources for clients, manage window objects, and sends mouse (or touch screen) and keyboard events to the active top-most client. If a client exits or dies for some reasons, it will not damage other clients and the server.

HISTORY

About ten years have pasted since MiniGUI was initially created at the end of 1998, and now it becomes much reliable and stable. During the past years, many remarkable changes have taken place in the MiniGUI project.

At the original, the version 0.2.xx was based on SVGALib and PThread (LinuxThreads). Then the version 0.3.xx had many enhanced features including Graphics Abstract Layer (GAL), Input Abstract Layer (IAL), and the support for multiple charsets and multiple fonts.

In version 1.0.00, we designed MiniGUI-Lite, which was more fit for some complex embedded systems, such as PDAs, Thin-Clients, or STBs. MiniGUI-Lite made the embedded systems more stable and efficient. The version 1.0.00 provided the native fbcon engine based on Linux frame buffer device directly as well.

In the development of version 1.1.00, we re-wrote the GAL and GDI interfaces, and provided some advanced video features, such as raster operation, transparent blitting, alpha blending, and video hardware acceleration. We also provided some important GDI functions, such as Ellipse, Arc, Polygon, and FloodFill.

In the development of version 1.6.0, we added advanced 2D graphics functions to MiniGUI. It provides the abstract logical pen and brush objects, and can be used to render advanced graphics objects.

In the development of version 2.0.x, we developed MiniGUI-Processes.

In the development of version 3.0.x, we introduced Look & Feel Renderer, BIDI text support, Non-rectangular window, double-buffer window, and other main features.
