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
Thanks a lot for your mail. It helps.
Essentially moved https://doc.qt.io/qt-5/stylesheet-reference.html#font-prop
from pixels to points and fixed the hardcoded layouts.
Adjusting the QT_AUTO_SCREEN_SCALE_FACTOR and QT_FONT_DPI to scale
ccordingly.

Too bad the Qt Widget stylesheet function only supports point sizes for
fonts. Points don't work for any other measurements,

Yes. Or set the QT_SCREEN_SCALE_FACTORS variable. Or both, or set the AUTO one
to 0. They interact in weird and sometimes
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.

Does your system know that its
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

Ok Thanks for your mail. Forgot to mention that Qt UI is based on
QWidgets(QPainter) with unicodes.
Is this the reason why auto scale attribute doesn't works and need to use
QFontmetrics to set point size for the DPI accordingly?

Officially:
size in inches = size in points / 72 *
Nope this didn't help. If setting pointsize appropriately for current
display 141 dpi would help to scale for other displays of different screen
sizes in future?
Is there any formula to calculate the font size in point size based on dpi
display which would work for all display sizes or just

I doubt there is a report. Simply accept that Qt 5 is right and Qt 4 is
Hello Thiago,
Thanks for your mail.
Am wondering if we need to set
Qcoreapplication::setAttribute(Qt::AA_EnableHighDPI as the dpi of the
device is 141 only or reduce the point size across UI and converting pixels
being used to pt sizes with fontconfig in Qt5?
Couldn't find the font size Qt 4.8

Yes, Qt 5 supports HighDPI.

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.
Shall upgrade the version early next year either

Does setting
QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
help? This should be more or less the first line in your code.
