QRawFont not recognised in qt4.8.5 cross-compiled for arm.

kpkale

I have a program where I am using the QRawFont to get outlines of a TTF Font Character and display on screen using QPainterPaths.
The program works perfectly OK when I compile using 4.8.1 on Windows OS, Ubuntu OS, Android OS. However, I am now trying to compile the program using qt4.8.5 cross-compiled for arm processor to be run on embedded linux where I get an error "error: ISO C++ forbids declaration of 'QRawFont' with no type".

The header has #include <QRawFont> and a private variable QRawFont *mfont; This error is seen on the variable declaration.
Moreover, when I try to type QRawFont, usually, it automatically shows the type for auto-completion. Even that is not seen. Instead, the auto-complete just shows QRAWFONT_H.

I tried searching for this problem on google but could not find a suitable thread even stating the problem hence decided to post a new topic.

Anyone with a solution? Thanks for reading this post.

Hi,

Are you sure your build is complete ?

kpkale

Thanks for your reply.

If I comment the part of my program which uses the QRawFont, the program is built completely and I can run the program on the device.

And the program as a whole runs successfully on all other OS's. I see this problem especially when cross-compiling for embedded linux on ARM processor.

From a quick look at the documentation it's possible that the class is not available for Qt for Embedded Linux

OH!! Thanks for this information, never guessed that the class might not be available itself.

Thanks for this information.

I am at present using the pathForGlyph function of the QRawFont to get the glyph outlines.
Could there be any other way to get the glyph outlines of a ttf font character avoiding QRawFont.

I have been trying to study the QRawFont... it is quite evident that the QRawFont uses the QAbstractFontEngine to get the glyph data using addGlyphOutlinesToPath. I tried a variety of ways to use this function but somehow i am unable to proceed ahead. The QFixedPoint that is required by the function is also not available in Qt Embedded.

ANy way to use this...

Out of curiosity, why doesn't QFont fit the job ?

kpkale

I dont know any method of getting the Glyph outline data using QFont and get it in form of a path. If you know one, it would be great if you could share it with me. Thanks.

Maybe through QAbstractFontEngine
