Question

I want to install TTF fonts on the host computer (running Windows) during installation of a software I make. Installing fonts on windows means 2 things :

• Copy TTF files in c:\windows\fonts. That is easy to do.
• Register the fonts that is : update the Windows Registry for Windows to update its font list. My question is : how can I do this with install4j ?

Thanks in advance for any help !

Well, I’ve done it “the hard way”, but it works. Here’s my code :

String fontRegKey;
if (Util.isWindows9X())
{ fontRegKey = "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Fonts"; }
else
{ fontRegKey = "SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Fonts"; }
String [] fontFilesNames = new String[]
    {"braille_tbfr2007_b-2.ttf","BrailleTBFr2007INSHEAb_thermo.ttf","LouisLouis.ttf","LouisLouisThermo.ttf"};
String [] fontNames = new String[]
    {"Braille TBFr2007 INS HEA (TrueType)","Braille TBFr2007 INS HEA thermo (TrueType)",
    "LouisLouis Braille (TrueType)","LouisLouis Braille Thermo (TrueType)"};

for (int i=0 ; i<fontNames.length ; i++)
{
    boolean write = WinRegistry.setValue(RegistryRoot.HKEY_LOCAL_MACHINE, fontRegKey,fontNames[i], fontFilesNames[i]);
}

if (Util.isAtLeastWindowsXP()) //security : delete system font cache
{
    File sd = WinFileSystem.getSystemDirectory();
    File f = new File (sd.getAbsoluteFile()+"\\FNTCACHE.dat") ;
    if (f.exists()) {f.delete();}
}
return true; //mandatory for the script

Three final things :

• This is script is a Run Script Action i put in the Finish screen of the installer.

• Be sure to run this script only in windows environment because your installer will crash under other systems.

• This seems to be unnecessary for WinXP but indispensable for Win7 for the fonts to be accessible in the font list after installation.
