Hey,
I just found the Interface com.sun.star.awt.XPrinterServer which
provides a method getPrinterNames.
But: which service supports this Interface? I cannot find one?
Can somebody give me an advice?
com.sun.star.awt.PrinterServer
getting the available printer names is one of the most wanted things by
extension developers.
It seemed that there was no API for getting the available printers'
names, nor the tray, etc. see issues 87883 and 87495
http://www.openoffice.org/issues/show_bug.cgi?id=87883
http://www.openoffice.org/issues/show_bug.cgi?id=87495
As I said somewhere else
(http://dba.openoffice.org/servlets/ReadMsg?listName=users&msgNo=6097)
IMHO, the one that developed the printing API was too lazy: internally
all these is available cf. the Printer class in /vcl/inc/vcl/print.hxx
For 87883
static const std::vector< rtl::OUString >& GetPrinterQueues();
For 87495
USHORT GetPaperBin() const;
BOOL SetPaper( Paper ePaper );
et al.
How many month can take to wrap this into a new or existing
interface/service?
well, it seems that the one that developed VCLXPrinterServer was...
let's say not much careful:
com.sun.star.awt.PrinterServer can *NOT* be used from OOo Basic, because
com::sun::star::lang::XTypeProvider is not declared to be inherited by
that class (although it is implemented in the class). So for OOo Basic,
createUnoService("com.sun.star.awt.PrinterServer") returns indeed an
object not null, but that implements no interfaces, so it has no methods.
And to the printer names issue: there *is* an API for that, in
com.sun.star.awt.XPrinterServer, as we all thought in first time but
couldn't see it from Basic: VCLXPrinterServer::getPrinterNames()
implements what I suggested above to solve i87883, that is
Printer::GetPrinterQueues()
::com::sun::star::uno::Sequence< ::rtl::OUString >
VCLXPrinterServer::getPrinterNames( )
throw(::com::sun::star::uno::RuntimeException)
{
const std::vector<rtl::OUString>& rQueues =
Printer::GetPrinterQueues();
sal_uInt32 nPrinters = rQueues.size();
::com::sun::star::uno::Sequence< ::rtl::OUString > aNames(
nPrinters );
for ( sal_uInt32 n = 0; n < nPrinters; n++ )
aNames.getArray()[n] = rQueues[n];
return aNames;
}
Besides this, css.lang.XserviceInfo is not implemented.
I created a patch (attached here), and re-builded the toolkit module:
now XPrinterServer.getPrinterNames() returns the available printers in
OOo Basic.
I still wonder if what I quoted in
http://www.openoffice.org/servlets/ReadMsg?list=dev&msgNo=22097 is still
true:
According to
http://api.openoffice.org/servlets/ReadMsg?listName=dev&msgNo=6496 (from
2003 but still applies)
"the interface was designed for an OOo/SO
running on a server where the printers are connected at the client.
Thus. for printing the client is a print server."
So if Cor is looking for something he can use in OOoBasic with a normal
printer, c.s.s.awt.XPrinterServer won't work (at least in my notebook
where I have no printer server,
createUnoService("com.sun.star.awt.PrinterServer") instantiates an
object only supporting com.sun.star.uno.XInterface , that is,
c.s.s.awt.XPrinterServer is not available)
at *least* XPrinterServer.getPrinterNames() *does* work, I will have to
check the other methods.
Regards
Ariel
PS: Carsten, don't think I forgot the Menu API enhancement, I'm still
working on it, it happened that it took me more time to implement than I
thought (I had to debug vcl, etc.) . I'll try to finish something this
weekend and write a wiki page about the API enhacement proposal in order
to discuss here.
