Wt

Hi Alan,

I can't reproduce this on the current git version... Do you have any extra information on this bug? Does it work with latest git? Does the problem only exist with chrome or also on other browsers?

BR,

Wim.

It doen't work with the latest git version too.

Now I get 'Uncaught SyntaxError: Unexpected token +' on this line:

if(Wt3_3_0.getElement('col4idsf').getContext){new Wt._p_.ImagePreloader(['/icons/sp.jpg']...

It doesn't work on any browser.

Can you provide a full example that demonstrates the error?

Also, developer tools let you format the JS output when you click the '{}' icon, you'll get a better indication on what exactly is wrong.

Wim.

I don't know js good enough to get what is wrong by reading the sources.

Here's my full code:

class ImagePainter : public Wt::WPaintedWidget
{
public:
    ImagePainter(Wt::WContainerWidget *parent = 0);

protected:
    void paintEvent(Wt::WPaintDevice *paintDevice);
};

ImagePainter::ImagePainter(Wt::WContainerWidget *parent)
    : WPaintedWidget(parent)
{
    resize(400, 400);

    Wt::WCssDecorationStyle style = decorationStyle();
    style.setBorder(Wt::WBorder(Wt::WBorder::Solid, 4, Wt::red));
    setDecorationStyle(style);
}

void
ImagePainter::paintEvent(WPaintDevice *paintDevice)
{
    Wt::WPainter painter(paintDevice);
    Wt::WPainter::Image image("icons/sp.jpg", 199, 253);
    painter.drawImage(0.0, 0.0, image);
}

Wt::WApplication*
createApplication(const Wt::WEnvironment& env)
{
    Wt::WApplication *app = new Wt::WApplication(env);

    ImagePainter *p = new ImagePainter(app->root());

    return app;
}

int
main(int argc, char **argv)
{
    return WRun(argc, argv, &createApplication);
}

I cannot reproduce this, it works for me.

Please let Chrome developer tools format the JS and look at the line where the JS error is. If you don't see it, copy-paste about 10 lines (that include the error) here so that we can take a look at it.

BR,

Wim.

Here is the code:

if (Wt3_3_0.getElement('cou39vwg').getContext) {
new Wt._p_.ImagePreloader(['/icons/sp.jpg'], function(images) {
    var ctx = Wt3_3_0.getElement('cou39vwg').getContext('2d');
    ctx.clearRect(0, 0, 400, 400);
    ctx.save();
    ctx.save();
    ctx.lineWidth = 1;
    ctx.lineCap = 'square';
    ctx.font = '10.0pt sans-serif ';
    ctx.drawImage(images[0], 0, 0000000e+00, 0, 0000000e+00, 1, 9900000e+02, 2, 5300000e+02, 0, 0000000e+00, 0, 0000000e+00, 1, 9900000e+02, 2, 5300000e+02);
    ctx.restore();
    ctx.restore();
});
}

Sorry, that was my mistake.

I tried to build my app with some Qt objects.

I created a QCoreApplication object in the main function. So I removed it, and everything is ok now.
