When opening an xhtml file with a chart one should be able to select a bar from the chart. Following page http://www.highcharts.com/demo/column-drilldown has a bars where selecting a bar should open different view. With QtWebKit (in Qt 4.7.4) the mouse press is not recognized thus selecting a bar is not possible.
Steps to Reproduce:
With the following (simple) code the issue can be reproduced:
int main(int argc, char *argv)
QApplication a(argc, argv);
Selecting a bar has no effect.
With Qt 4.6.2 it was possible to open another view by selecting a bar. (The chart works with Firefox, Safari and IE)
Root cause is the same as in Bug 60875 .
Problem is in DOM4 construction of TouchStart where if touch is not available TouchStart is null Source/WebCore/bindings/scripts/CodeGeneratorJS.pm .
The draft specification for TouchEvents defines it to be undefined. http://www.w3.org/TR/2011/WD-touch-events-20111027/
Jani is preparing a patch for 60879.
