Hey all,
Strange bug founded. Assume we have the code below:
// code inside some container widget
// ...
popupMenu_ = new Wt::WPopupMenu();
addChild(popupMenu_);
Wt::WSignalMapper< ItemId >* m
= new Wt::WSignalMapper< ItemId >(popupMenu_);
m->mapConnect
(popupMenu_->addItem(tr("id1"))->triggered(), Id1);
m->mapConnect
(popupMenu_->addItem(tr("id2"))->triggered(), Id2);
m->mapped().connect(this, &MyWidget::handlePopup);
Wt::WPushButton* b = new Wt::WPushButton("test", this);
b->clicked().connect(this, &MyWidget::handleClick);
void MyWidget::handleClick(Wt::WMouseEvent me)
{
popupMenu_->popup(me);
}
void MyWidget::handlePopup(ItemID id)
{
Wt::WApplication* const app = wApp;
switch(id) {
case Id1:
app->setInternalPath("/path/to/id1");
case Id2:
app->setInternalPath("/path/to/id2");
}
When the button "test" clicked for a first time all works fine. Subsequent
clicks
does not pop up the menu. We tried to investigate the problem and find out
that the method WWidget::hide() invoked by WPopupMenu::done() has invoked
after the WObject::show() invocation when on a second and subsequent clicks
on a button and prevents pop up a menu.
Regards,
Dmitriy
