Wt

Hey Rob,

There was an issue with recording the mouseup event. This has been fixed in latest git.

Nevertheless, the problem persists when the context menu pops up --- then the mouse up event is lost to the context menu itself.

To use this reliably you need to disable the context menu. See this test case:

#include <Wt/WApplication>
#include <Wt/WContainerWidget>
#include <iostream>

using namespace Wt;

class  Test : public WApplication{
private:
  WVBoxLayout *vBox;
public:
  Test(const WEnvironment& env) 
   : WApplication(env)
  {
    WContainerWidget *container = new WContainerWidget();
    container->resize(500,500);
    container->mouseDragged()
      .connect(boost::bind(&Test::print, this, "drag"));
    container->mouseWentUp()
      .connect(boost::bind(&Test::print, this, "up"));
    container->mouseWentDown()
      .connect(boost::bind(&Test::print, this, "down"));
    root()->addWidget(container);

    container->setAttributeValue
      ("oncontextmenu",
       "event.cancelBubble = true; event.returnValue = false; return false;");
  }

  void print(std::string str) {
    std::cerr << str << "\n";
  }

};

WApplication *createApplication(const WEnvironment& env){
  return new Test(env);
}

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

Regards,
