Widgetset
Widgetsets support platform-sensitive development with the Lazarus IDE system. They act as adapter libraries that provide an interface between a platform-independent sourcecode written in Free Pascal and platform-specific system functions. Thus they allow for development of platform-native software without requiring to provide specific source code for different target platforms.
Widgetsets act as basis for the Lazarus Component Library (LCL).
Available widgetsets
[edit]Currently (June 2020), the development status of widget toolkit interfaces is roughly as follows:[1]
| Widget set | Supported operating systems | Status |
|---|---|---|
| Windows API, GDI | Windows | Mainstream use |
| Windows CE API, GDI | Windows CE | Mainstream use |
| GTK+ 1.2.x | Linux (via X11) | Deprecated |
| GTK+ 2.8+ | Linux (X11 and framebuffer), Windows, and Mac OS X (via X11) | Mainstream use |
| GTK+ 3.x | As Gtk2 | Alpha |
| Qt 4.5+, 5.6+[2] | Linux (X11 and framebuffer), Windows, Mac OS X | Mainstream use. Works in Windows, Linux, Mac OS X, Maemo, etc |
