QString with diacritical characters

gandiii

Hello,

I have made a keyboard with all characters I need, also
with diacritical characters.
A Signalmapper mapped with the hex-Code of the character, gives me the
pressed key.
But if I press one of the diacritical characters, the program
doesn't accept it.

For example:
ushort from Signalmapper is 0x010C (C with caron).
I append it to the string tmpString.append(QString::fromUtf16(0x010C,1));

But this doesn't work, can anybody help me with my problem.
I really don't know how I get the diacritical symbols working.

I think your use of fromUtf16 is wrong. It expects a c type string in the right encoding, but you're giving it a UTF code point and a length 1. Perhaps you're looking for [[doc:QChar]]? You can create those using the code point, and you can append them to a QString.

now I tried it with QChar and it doesn't work.

example:
@Signalmapper -> 0x0152 -> QChar test(0x0152)
QString testString;
testString.append(test);
ui.lable->setText(testString);
@

Edit: added @ tags around code section; Andre

The, something else is off. This code works for me:
@

MainWindow::MainWindow(QWidget *parent) :
QDialog(parent),
ui(new Ui::Dialog)
{
ui->setupUi(this);
QChar test(0x0152); //this code might as well come from somewhere else...
QString testString;
testString.append(test);
ui->label->setText(testString);
}

@

And please, use @ tags around code sections. They become much easier to read.

Is there a global settings for the encoding of a label?
I wrote the code like above, but it doesn't work.
could this be a problem of the embedded linux?

andre

Well, I got this as the label: Œ
That is the correct code point according to the character map application. Using 0x010C results in Č as the contents of my label. Looks good to me.

Are you sure your font actually contains these code points?

i am using the Liberation font and this pdf "Liberation":http://www.ascendercorp.de/pdf/Liberationsans.pdf shows the included charaters.
i tried it with Æ and this works.

I have found the problem.
qt uses the fonts in /usr/lib/fonts/ instead of /usr/share/fonts/
and if the label is set to Liberation, qt uses a other font
in its folder.
