[PyQt] disconnect everything connected to an object's signals
Hi everybody,
Qt Assistant says that:
Disconnect everything connected to an object's signals:
disconnect(myObject, 0, 0, 0)
0 may be used as a wildcard, meaning any signal, any receiving object,
or any slot in the receiving object, respectively.
But if I do:
disconnect( myObject, 0, 0, 0 )
I obtain:
disconnect( myObject, 0, 0, 0 )
TypeError: disconnect() takes exactly 1 argument (4 given)
What is the problem?
My machine: Linux, Qt 4.4.0, PyQt 4.4.4
Thanks in advance,
Julien

[PyQt] Text orientation in a QTableView Header
Hi List, I was wondering if there was a simple way to change the orientation of the text in a QTableViews QHeaderView? I would like to be able to write the coloumn lables vertically rather than hoziontally for a largenumber of coloumns that contain large labels and single diget numbers in the data fields. Is there a way to do this or am I looking at making a new Header and changing the way it paints its text? If I have do this any example code would be neat. -bd ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] What about qtbrowserplugin?
QtSoftware has in the add-ons catalog qtbrowserplugin package. I wonder if this framework could get Python API and the possibility to write the plugins in Python? http://www.qtsoftware.com/products/appdev/add-on-products/catalog/4/Utilities/qtbrowserplugin ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] Page setup for printer defaults
Hello PyQt group, My application uses a Brother label printer to spit out labels. I'd like to do a Page Setup, say in my preferences dialog and then save the printer information in a settings so that we don't have to go through a print dialog. Currently I go through the print dialog once then use the resulting QPrinter for subsequent print operations and that works fine. I can assign the printer name to QPrinter so that it at least defaults to the correct printer, but I'm having trouble figuring out how to set the appropriate variables to match the printer to the specific label size. Specifically, in the print dialog, I use the properties dialog to select the label size. On return I can examine things like pageSize, pageRect, paperSize, paperRect but I can't seem to set pageSize and can't find methods for setting the page or paper Rect. For example, after the print dialog, pageSize returns 30 but setPageSize(30) causes an invalid type error since it expects a QPrinter.PageSize enum value. 1) How would you go about doing a PageSetup dialog, not Print Dialog, to both select a printer and it's default properties. 2) What needs to be saved and how can I restore the relevant properties. I'm used to working through these issues myself, an often find that once the question is asked, the answer seems to come on it's own, but this time I'm stuck.

[PyQt] Function pointers and SIP
Hi Phil, given a C++ object where you can register callbacks such as: void registerCallback(void (*cb)(void*), void* user_data); or void registerCallback(std::tr1::functionvoid (void) cb); how would you wrap them in SIP? Is there some code in PyQt that I can look at? -- Giovanni Bajo Develer S.r.l. http://www.develer.com ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

I had a general idea of course, but I wanted to make sure there was not automa[tg]ic support by SIP which I wasn't aware of. The nearest example in PyQt is probably qInstallMsgHandler(). Thanks. Why the internal qtcore_MsgHandler uses SIP_BLOCK_THREAD/SIP_UNBLOCK_THREADS? Is that always needed or only if I have previously explicitly released the GIL? -- Giovanni Bajo Develer S.r.l. http://www.develer.com ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
