Bug #819
closedMouse-events with right click -> dragging bug
0%
Description
After a certain series of clicks Wt informs me that I'm dragging while I don't have any mouse buttons pressed in.
The series:
- left button down
- right button down
- right button up
- left button up
- move mouse (no buttons pressed)
[You should perform these without moving your mouse]
To reproduce this:
void HelloApplication::create()
{
WContainerWidget *container = new WContainerWidget();
container->resize(500,500);
container->mouseDragged().connect(bind(&HelloApplication::print, this, "drag"));
container->mouseWentUp().connect(bind(&HelloApplication::print, this, "up"));
container->mouseWentDown().connect(bind(&HelloApplication::print, this, "down"));
root()->addWidget(container);
}
void HelloApplication::print(std::string str)
{
cout << str << "\n";
}
gives me the following output on:
- chrome [no up events!]:
down
down
drag
- firefox [up events! but still not correct]:
down
down
up
up
up [-> extra click because we have to click away the pop-up from the right click]
drag

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,
koen
