Something changed or broken between Qt 4.8.6 and Qt 5.1.1 ...

Try this: http://sourceforge.net/projects/lcd-image-converter/files/beta/lcd-image-converter-20140608-beta.zip/download -----------------------------------------------

Test source:

#include "mainwindow.h"
#include "ui_mainwindow.h"

#include
#include

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

QString family = "Anonymous Pro";
QFontDatabase fonts;

QStringList styles = fonts.styles(family);
qDebug() << styles;

}

MainWindow::~MainWindow()
{
delete ui;
}

Qt 4.8.6 output:
("Bold", "Bold Italic", "Italic", "Normal")

Qt 5.1.1 output:
("Bold", "Bold Italic")

It works, thanks. Still the project team might think about how to create font files for the OpenType fonts with specified weights, instead of their TrueType corresponding versions, which in many cases there might be any. I have confirmed at least lcd-image-converter recognizes the fonts windows platform supports.

Hmm... Give me example, please.
I have installed first found OpenType ( http://www.fontspace.com/gluk/foglihtenno07 ) and it works, as i can see.

Archive with Anonymous Pro font contains 4 files:

Anonymous Pro "Bold Italic",
Anonymous Pro "Bold",
Anonymous Pro "Italic",
Anonymous Pro "Regular".

If you install "Bold", 2 styles will be accessible: ("Bold", "Bold Italic").
"Italic" -> ("Italic", "Bold Italic").
"Bold Italic" -> ("Bold Italic").
"Regular" -> ("Normal", "Bold", "Italic", "Bold Italic").

"Regular", "Italic" -> ("Normal", "Bold", "Italic", "Bold Italic").
"Regular", "Italic", "Bold" -> ("Normal", "Bold", "Italic", "Bold Italic").
"Regular", "Italic", "Bold", "Bold Italic" -> ("Normal", "Bold", "Italic", "Bold Italic").
"Regular", "Bold", "Bold Italic", "Italic" -> ("Normal", "Bold", "Italic", "Bold Italic").

"Bold", "Bold Italic", "Italic" and "Regular" -> ("Bold", "Bold Italic").
"Italic", "Bold", "Bold Italic" and "Regular" -> ("Italic", "Bold Italic").
"Italic", "Bold", "Bold Italic" -> ("Italic", "Bold Italic").
...

So, just install only "Regular" font (Anonymous Pro.ttf) or change order of files installation.
I think there is a bug in Qt font database filling.

Qt on Windows enumerates fonts using WinAPI function EnumFontFamiliesEx ( http://msdn.microsoft.com/en-us/library/dd162620%28VS.85%29.aspx ).
"If there are two fonts with the same name, only one is enumerated".

When font added to database:

add original font;
// add fonts windows can generate for us:
if (fontWeight <= DemiBold) {
add original font with Bold weight;
}
if (fontStyle not Italic) {
add original font with Italic style;
}
if ((fontWeight <= DemiBold) and (fontStyle not Italic)) {
add original font with Bold weight + Italic style;
}

If first registered font in family has Regular style, then added Regular, Bold, Italic and Bold Italic.
If first registered font in family has Italic style, then added Italic and Bold Italic.
...

Enumarating fonts with same name don't solve problem.

I do not know this is a bug or normal behavior. I have created a query in the bug tracker on qt-project... https://bugreports.qt-project.org/browse/QTBUG-40828

from lcd-image-converter.

Fixed with Qt 5.4 release.
