Re: [PyQt] %ConvertToSubClassCode across modules

It'd be nice to avoid some kind of runtime RTTI list that the submodule appends to on startup, but if that's what I have to do, that's alright ;) Just thought I'd check here first for any ideas. Your class (or your code) has to provide some form of RTTI. QEvent provides type(), QObject provides inherits(). You can also rely on the RTTI provided by the compiler (seems to not always work on Windows). PyQwt has code like: %If (CXX_DYNAMIC_CAST) %ConvertToSubClassCode // Walk the inheritance tree depth first in alphabetical order // This code is for Qwt4 and Qwt5 #ifdef sipClass_QwtArrayData if (dynamic_castconst QwtArrayData *(sipCpp)) sipClass = sipClass_QwtArrayData; else #endif #ifdef sipClass_QwtDoublePointData if (dynamic_castconst QwtDoublePointData *(sipCpp)) sipClass = sipClass_QwtDoublePointData; else #endif #ifdef sipClass_QwtPolygonFData if (dynamic_castconst QwtPolygonFData *(sipCpp)) sipClass = sipClass_QwtPolygonFData; else #endif #ifdef sipClass_QwtData if (dynamic_castconst QwtData *(sipCpp)) sipClass = sipClass_QwtData; else #endif sipClass = 0; %End %End Gerard ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] webView webPage
Hi I'm trying to make a special web navigator with the webview. But I like to manage the weblinks. With signal clickedLink I see that this is what I want, but don't work if I dont define to use this signal. This I see I can do with linkDelegationPolicy. I cannot define linkdelegationpolicy on a webview. Only on a webpage class. The questions are: - It's better use webview or other widget to navigate throug own HTML with own link management? - What influence webpage has on webview. Because webpage has a lot of functions that webview does not inherits. - Can I use webpage to see html, and how I use it? I try to find examples and documentation on google but it's too new, and documentation and examples for pyqt does not exists. Sorry my english.

Re: [PyQt] webView webPage
1. A WebView is ideal if you are Qt4.4+ 2. A WebView contains a WebPage. The WebView is a widget, whereas the WebPage is not - the WebView is the visual representation of the web page, hence the name. 3. When you create a WebView, it contains a WebPage. Add the WebView to one of your widgets. You use the page() member function of WebView to get the WebPage, and you can then set the link delegation policy and connect signals to that page object. This all works very well, BTW. ___ From: [EMAIL PROTECTED] To: pyqt@riverbankcomputing.com Sent: 05/31/2008 05:58 AM Received: 05/31/2008 06:05 AM Subject: [PyQt] webView webPage Hi I'm trying to make a special web navigator with the webview.

Re: [PyQt] Bug - PyQt 4.4.2 and Matplotlib 0.91.2

I am posting this in Matplotlib mailing-list too, but I thought that maybe some of you could have an idea about this? I don't think it is appropriate to post here unless it can be demonstrated that there is a performance issue specifically related to PyQt and not Matplotlib or Qt. We continue this discussion on the matplotlib mailing list. ___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
[PyQt] Can't create a QImage?
Hi! I'm very new to PyQt (just started using it today) and also quite new to Qt in general... I have a problem creating a QImage. No matter what I do, it creates a null one... here's the output I get after I try to create a 10x10 QImage: gt;gt;gt; image = qt.QImage(qt.QSize(10,10), 4) gt;gt;gt; image.width() 0 gt;gt;gt; image.height() 0 gt;gt;gt; image.depth() 0 The third parameter means the RGB32 format... for some reason, when I type qt.QImage.Format_RGB32 there instead, I get the error AttributeError: Format_RGB32. Can someone help me create a QImage? By the way, if I replace qt.QSize(10,10) with simply 10, 10 the result is exactly the same...___ PyQt mailing listPyQt@riverbankcomputing.com http://www.riverbankcomputing.com/mailman/listinfo/pyqt
