Re: [Interest] Qt5 font size issue with fontconfig
Hello Thiago, Couple of questions..May I know why we don't see the large font issue in ubuntu though Qt5 is configured with -qt-xcb and fontconfig as the point sizes that work for ubuntu are not applicable for target? Does it makes sense to check the below suggested env variables only on target with large lcd size 10" instead of ubuntu as the fonts used are different in X11 and the graphics rendering being different namely linuxFB?

Re: [Interest] Qt5 font size issue with fontconfig
Ok Thanks for your mail. Yes moved to point size. Though I set the application font in point size being 12pt(default font point size), it doesn't adjusts accordingly across all UI screens or rest of application. For example, the pushbutton font text appears larger. Inorder to adjust across all the screens, do I need to set export QT_AUTO_SCREEN_SCALE_FACTOR=1?

Re: [Interest] Qt5 font size issue with fontconfig
Hello Thiago, In our application, based on DPI 141(screen size: 5.7" 480X640), the application font is set as 7pt based on the below calculation where px is 14 to look the font normal. double pxToPt(double px, double dpi) { return px*72/dpi } but the font size on target is small even though we set QCoreApplication:: setAttribute(Qt::AA_EnableHighDpiScaling); So if we use default font to retrieve the default font point size, it shows as 12pt which looks font size normal on display. QFont f; int defaultFontSize = f.pointSize(); Question is if we need to use default font point size for the current reference DPI display and set QCoreApplication::setAttribute(Qt:: AA_EnableHighDpiScaling) so that it scales for the 8" or 10" display? Though we need to convert existing pixel size to point sizes in the application code and use layouts in some parts of code instead of setting fixed width or any hardcoded values. Incase we need to show larger font, do we need to increment 4pt from the reference 12pt incase it is correct? Appreciate for your feedback in this regard.

Thanks a lot for your feedback. Could you please let me know the bug that has been fixed in Qt 4.8? Yes shall reduce the point size as it appears the font size is large unlike Qt4.8 and the text is truncated in table view rows and other text in UI.

Most likely, Qt 5 is displaying the fonts correctly and Qt 4 isn't because Qt 4 didn't support HighDPI. In other words, the bug that existed has been fixed.

Hi, After porting the Qt 4.8 application to Qt 5.6.3 on embedded Linux(Yocto) with fontconfig, the font sizes appear larger on target. The Qt 4.8 application font size setting with 14pt default font appears larger in Qt 5.6.3 with fontconfig and needed fonts added in default fontconfig directory /usr/share/fonts. The dpi of the device is 141. Do I need to reduce the font size pt or set any environment variable scale factor so that text appears normal? Any suggestions are much appreciated.
