Listing 9-6. The declaration of the event filtering class #ifndef LINKFILTER_H #define LINKFILTER_H #include <QObject> class LinkFilter : public QObject { Q_OBJECT public: LinkFilter( QObject *parent=0 ); signals: void linkClicked( const QString &); protected: bool eventFilter( QObject*, QEvent* ); }; #endif // LINKFILTER_H The actual filtering takes place in Listing 9-7. All events of the type WhatsThisClicked are handled. The QEvent object is cast into a QWhatsThisClickedEvent object from which the href property is emitted through the linkClicked signal. Make sure to call the QWhatsThis:: hideText method that hides the What s this box before the signal is emitted and any action is taken. Finally, handled events return true, preventing any further event handling. All other events return false informing Qt that the event is ignored. Listing 9-7. Filtering the events for WhatsThisClicked events bool LinkFilter::eventFilter( QObject *object, QEvent *event ) { if( event->type() == QEvent::WhatsThisClicked ) { QWhatsThisClickedEvent *wtcEvent = static_cast<QWhatsThisClickedEvent*>(event); QWhatsThis::hideText(); emit linkClicked( wtcEvent->href() ); return true; } return false; } To test the LinkFilter class a simple dialog class, LinkDialog, was created The dialog has a constructor and a slot: showLink(const QString&). (Listing 9-8 shows the constructor of the dialog.) java ean 13 generator EAN - 13 Java Barcode Generator/Class - TarCode.com

Any print statements you add to your tests are displayed only if the test fails or results in an error. Try modifying the test_subtract() function so that it looks like this: def test_subtract(): a = 3 print "a is %s"%a b = a + 1 print "b is %s"%b c = b-1 print "c is %s"%c assert b-a == c If you run the test again, you ll see the following extra information displayed after the AssertionError: -------------------- >> begin captured stdout << --------------------a is 3 b is 4 c is 3 --------------------- >> end captured stdout << ---------------------From this you can easily see that 4-3 != 3, but the test output wouldn t be cluttered with these debug messages unless the test failed. If you would prefer nose to always print debug messages like these, you can use the -s option so that it doesn t capture the standard output stream. asp.net create qr code, code 39 barcode font for crystal reports download, crystal reports upc-a barcode, winforms ean 13 reader, winforms upc-a reader, crystal report ean 13 font java ean 13 generator JavaScript Barcode Generator - bwip-js

First a LinkFilter is created and installed as an event filter for the dialog. The linkClicked signal is connected to the showLink slot of the dialog. Notice that the WhatsThisClicked event is passed through the dialog so you can intercept clicked links for all widgets in the dialog here. Since the filter is installed on the dialog it is possible to install the filter from a main window before showing the dialog. After the filter is installed, a QPushButton widget is created and the What s this text is set. To create a link, the <a href='nnn'> ... </a> tag is used. The nnn part is the string passed as the href property of the QWhatsThisClickedEvent and then passed on through the linkClicked signal. The text between the <a href=...> and </a> parts is the text that will be shown as a link. Before the constructor ends, the push button is placed in a layout. Listing 9-8. Setting up a dialog with the LinkFilter event filter LinkDialog::LinkDialog() : QDialog() { LinkFilter *filter = new LinkFilter( this ); this->installEventFilter( filter ); connect( filter, SIGNAL(linkClicked(const QString&)), this, SLOT(showLink(const QString&)) ); QPushButton *button = new QPushButton( "What is this " ); button->setWhatsThis( "This is a <a href='test link'>test link</a>." ); QGridLayout *layout = new QGridLayout( this ); layout->addWidget( button, 0, 0 ); } Figure 9-8 shows the What s this text and the link being shown. When the user clicks the link, a QWhatsThisClickedEvent is triggered, the linkClicked signal is emitted, and the showLink slot is triggered. The source code of the slot is shown in Listing 9-9. java ean 13 Generate barcode image with Javascript (. JS ) script and Bytescout ...
