1. Better handling of hasPreciseScrollingDeltas and SPI_GETWHEELSCROLLINES. The scrolling in LCL trunk is much too fast and imprecise. This improves the feel of things using both a mouse wheel and the touchpad. I don't like having the 15 for average line height hard coded in it, but I haven't seen any cases where it causes problems. 2. In the case where it sees a scroll in both X and Y directions, it filters it in favor of the last scroll direction. This makes vertical scrolling documents using the touchpad better, since you're less likely to inadvertently scroll horizontally. 3. Msg.WheelDelta is a SmallInt, so this caps the values to High/Low(SmallInt), rather than the underflow/overflow that occurs currently. That fixes the issue this bug report specifically is about. |

Welcome to Lazarus
Lazarus is a Rapid Application Development Tool for Free Pascal. It comes with the LCL - Lazarus component library, which contains platform independent visual components like buttons, windows, checkbox, treeview and many, many more. The LCL is platform independent, so you can write an application once and then compile for various platforms without changing code.
Free Pascal is a fast Object Pascal compiler (and more), that runs on more than 20 platforms (Linux, Windows, BSD, OS/2, DOS, PowerPC, and many more).
The LCL currently supports:
- Linux/FreeBSD (GTK2, Qt4 and Qt5)
- all flavors of Windows (even WinCE)
- Mac OS X (Cocoa, Carbon, GTK2, Qt4, Qt5)
There is an experimental support for:
- GTK3
- Solaris
The LCL still contains code for GTK1, although that is obsolete.
Compilation:
You don't need ./configure, just do make clean bigide.
(BSD users: gmake clean bigide).
This will create the Lazarus executable with a lot of packages. Start it and enjoy.
If the above gives an error, you can try to build a minimal IDE with
make clean all.
(BSD users: gmake clean all).
Installation and Requirements:
See docs/INSTALL.txt file.
Usage:
Start the IDE with:
cd your/lazarus/directory
./lazarus
Documentation:
The official site is www.lazarus-ide.org. Documents about specific topics can be found at https://wiki.freepascal.org/Lazarus_Documentation. Examples on how to use the LCL can be found in the 'examples' directory. Help, documents and files about Free Pascal are at www.freepascal.org.
Mailing list:
There is a very active and helpful mailing list for Lazarus, where the developers interact, share ideas, discuss problems, and of course answer questions. You can subscribe at http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
How to help Lazarus:
If you find bugs, don't hesitate to use issue tracker, or send an email to the list. Lazarus source code and issue tracker are located at GitLab: https://gitlab.com/freepascal.org/lazarus/lazarus
