MySQL Workbench 6.1
MForms is a small GUI toolkit library written for use in the MySQL Workbench project. It is small and cross-platform, while providing access to fully native controls (through .NET in Windows, GTK in Linux and Cocoa in MacOSX). It is not meant to be a full-fledged control library, but instead a light-weight and simple library that allows writing simple forms that will work in any supported platform. It is used by Workbench in some specific parts where the UI requirements are not very complex, such as in wizards, simple confirmation dialogs and the Administrator feature. The library is written in C++, but a Python wrapper is available, making it possible to easily write cross-platform plugins with simple to moderately complex GUIs.
Because each platform has widgets of different sizes, with different layout characteristics, using absolute coordinates and sizes for layouting would not work very well. A dialog written in Windows containing text and a couple of buttons could look fine in the OS where it was written in, but would look cluttered and probably too small on Mac OS X. To work around that, MForms uses dynamic layouting containers instead of static coordinates to place and size controls, similar to what GTK uses. Basically, there are several types of containers where you can place one or more controls inside, each having a specific layouting behavior.
