[PyQt] desktop workspace
I am trying to save the geometry and and the workspace where the application has been closed. Is there a way with Python/Qt to get the info on the workspace number!? -- Emmanuel ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

I presume that by BLEEP you do not mean beep, otherwise you could use this: http://doc.qt.nokia.com/4.7/qapplication.html#beep David :-) ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt

No, you just convert the QString to unicode.

See above.

Sure, just do
import sip
sip.setapi('QString', 2)
before any PyQt imports, which does convert QString to unicode behind
the scenes. Anyway, no need to encode/decode utf-8 strings here.

I guess, it mostly depends on the performance of your bleep algorithm.
The rest is operating with compiled code, which should be sufficient.

I present a document to a user in a QPlainTextEdit widget. The widget nicely handles most editing functions, but there is a unique operation I want to provide. When the user selects Edit > BLEEP, the app is supposed to BLEEP the document. BLEEPing is not something Qt does, I have to implement BLEEP with native Python code. So when the user says BLEEP it, I must: 1. Use QPlainTextEdit toPlainText() to get the document text as a QString 2. Use QString toUTF8() to get Utf-8 text that Python can use 3. Apply my Python logic to BLEEP the text 4. Use QString fromUtf8() to return to a QString 5. Use QPlainTextEdit fromPlainText() to replace the document with the BLEEPed contents. Does this sound right? Can PyQt do #2 and #4 automagically? And what are the performance implications when a document might have one or two megabytes of text?
