Help!! cannot load Fonts!

[gattogio]

Hi,
I'm using Qt 4.2 on Linux (Gentoo)...
When i try to do

int id = QFontDatabase::addApplicationFontFromData( myFont );

int id = QFontDatabase::addApplicationFontFromData( myFont );

To copy to clipboard, switch view to plain text mode 

or

int id = QFontDatabase::addApplicationFont( "/../fonts/myFont.ttf" );

int id = QFontDatabase::addApplicationFont( "/../fonts/myFont.ttf" );

To copy to clipboard, switch view to plain text mode 

it always returns -1....

Any suggestion to resolve the problem???

[aamer4yu]

are u using the correct path ?? may be it is not able to find the font....

also in the docs its written

int QFontDatabase::addApplicationFont ( const QString & fileName ) [static]
.....
Note: Adding application fonts on Unix/X11 platforms without fontconfig is currently not supported.
This function was introduced in Qt 4.2.

hope this might help u little

i am not sure what fontconfig is ...

[gattogio]

Yes,
i have fontconfig installed and the font path is surely correct!

int id = QFontDatabase::addApplicationFont( "/../fonts/myFont.ttf" );

int id = QFontDatabase::addApplicationFont( "/../fonts/myFont.ttf" );

Are you sure "/../fonts/myFont.ttf" is a correct path? It starts with a slash which means the root of the filesystem tree... maybe it should be "../fonts/myFont.ttf"?

[gattogio]

"/../fonts/myFont.ttf" is an example Path! the real path is surely correct.
All the code is 100% correct.

I think my problem depends on linux font configuration.. but I don't know how to fix it. I have fontconfig installed, but don't know how it works and if it works, and don't know what i can check...

If your text is antialiased then fontconfig probably works correctly. You can additionally verify if Qt is linked against fontconfig (use ldd).
