Is it possible to create a combo with paper sizes?

Dear all

I am trying to do create a combo with paper sizes on the system.

I try to do it with
QList<QPrinter::PaperSize> QPrinterInfo::supportedPaperSizes () const;

But I want able to get the list yes.

This should work:

Code:

---

QMetaEnum paperSizes = QPrinter::staticMetaObject().enumerator(QPrinter::staticMetaObject().indexOfEnumerator("PaperSize"));
QStringList list;
QList<int> valueList;
for(int i=0;i<paperSizes.keyCount();i++){
    list << key(i);
    valueList << value(i);
}
QComboBox *box = new QComboBox;
for(int i=0;i<list.count();++i){
  box->addItem(list.at(i), valueList.at(i));
}

---

I have a error like

staticMetaObject is not a member of qprinter

Ouch... QPrinter is not a QObject... Well... this won't work then :)

can we use

supportedPaperSources ?

Have a look at QPrintDialog sources.

Edit: Sorry, QPageSetupDialog...

I was able to get the dimentions of the pages right now, but I still cant get the names, maybe this would be helpfull for someone

Code:

---

QPrinterInfo pinfo;
	QList<QPrinter::PaperSize> paperSizes = pinfo.defaultPrinter().supportedPaperSizes();
	QPrinter pppp;
	QSizeF sizef;
	QVariant height_variant;
	QVariant width_variant;
	int height;
	int width;
 
	for(int i=0;i<paperSizes.count();++i){
		pppp.setPaperSize(paperSizes.at(i));
 
		height = pppp. paperSize(QPrinter::Millimeter).height();
		width = pppp. paperSize(QPrinter::Millimeter).width();
 
		height_variant = height;	
		width_variant = width;
		comboBox->addItem(height_variant.toString() + "x" + width_variant.toString());
	}

That's not really an answer. Qt can do such things on its own but it requires the enum to be defined in a QObject which is not the case here. I suspect it would be possible to declare a dummy QObject and declare the paper size enum there but it doesn't seem like a good solution.

Ok. Then the routine you written above in this thread would work, right ? Since QPrinter is not derived from QObject, I suggested the link regarding C++. Is there any reason why QPrinter is not a part of QObject ?

Yes.

Ok, but then you have to manually construct mapping from enum to strings so you can just insert those strings to the combo-box instead. The same amount of work. I think the solution the thread author is looking for is to do this automatically.

There is no reason for it to be a QObject.
