There is a Microsoft Windows launcher for FreeMind, written in C.
Function
This launcher provides the following.
| Feature | Description |
|---|---|
| Icon | Has an icon. |
| Dropping a file | When a file is dragged and dropped over the launcher, it is passed to Java application as a parameter. |
| Argument passing | When the launcher is run from a DOS console and given multiple arguments, all are passed to the Java application. |
| Changing to directory | The launcher has to reside in a directory relative to the application directory. However, it can be run from any other directory. Therefore, if you assign the launcher to a file type, the application is run correctly with the file passed as an argument. |
Compilation
This launcher for Microsoft Windows was compiled using Dev-C++.
To download Dev-C++, go to project page at SourceForge.
To get Dev-C++ working on Windows Vista, follow this forum thread. The thread instructs you to install MinGW separately, and to set the directories in the settings of Dev-C++ to the ones of MinGW.
To recompile it, open the project Freemind.dev with Dev-C++, and compile the project.
The underlying compiler of Dev-C++ was MinGW.
Files
| File | Description |
|---|---|
| Freemind.dev | Project file, to be opened in Dev-C++ |
| Freemind.c | The source code |
| Makefile.win | Written by Dev-C++. Contains compiler settings. |
| FreeMind.ico | Application icon file, with light bulb. |
| FreeMind-document.ico | Document icon file, with light bulb. |
| FreeMind-butterfly.ico | Icon file, with butterfly icon, instead of light bulb icon. There is no document icon for butterfly. |
| Icon1.rc | Plain text, resource file, describing the location of icons. Contains:
#include <windows.h> //100 ICON "FreeMind-butterfly.ico" 100 ICON "FreeMind.ico" 101 ICON "FreeMind-document.ico" |
| Icon1.o | Object file compiled from Icon1.rc and FreeMind.ico (or FreeMind-buttefly.ico) |
| Freemind.o | Object file compiled from Freemind.c |
| Freemind.exe | Executable built from Freemind.o and Icon1.o |
| strip-FreeMind-executable.bat | A batch file for reducing the size of the resulting Freemind.exe, to be executed after the Freemind.exe has been created. |
Not all of these files are present in CVS; some are only present in the patches.
Memory constraint
The launcher contains a memory constraint for the Java runtime environment:
- In Freemind.c
char *argument_allowing_more_memory = "-Xmx256M";- the meaning of "-Xmx": the maximum heap size
When FreeMind reaches this upper limit, it starts to freeze.
Patches
| Patch | Description |
|---|---|
| Windows launcher | Features butterfly icon. An updated launcher features more; see the patch. |
| Launcher: Metadata, small cosmetic changes |
Gotchas
Things to watch
- FreeMind.ico must be a real icon, not an icon created by changing the extension of a file from bmp to ico.
