How to detect when a QWebEngineView widget is opened/closed? - c++

Question

I'm adding the discord widget from widgetbot to a grid layout in a way it can expand above other widgets, the problem is, even when the widget is 'closed' the QWebEngineView widget occupies the entire area blocking things below it to be clicked:
I thought of setting a maximum size to the widget when it is opened and another when it's closed so it doesn't overlay other widgets when it's not 'opened'.
I tried installing an event filter but it didn't throw any event when the widget is opened/closed, would like to ask what other way I could detect it?
#include "discordwidget.h"
MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
{
ui.setupUi(this);
auto wdgt = new DiscordWidget(this);
}
//discordwidget.h
#include <QtWebEngineWidgets>
class DiscordWidget : public QWebEngineView
{
Q_OBJECT
public:
DiscordWidget(QWidget* parent = 0) : QWebEngineView(parent)
{
this->page()->setBackgroundColor(Qt::transparent);
// Tutorial: https://docs.widgetbot.io/embed/crate/tutorial/#getting-started
this->page()->setHtml(R"(
<script src='https://cdn.jsdelivr.net/npm/#widgetbot/crate#3' async defer>
new Crate({
server: '', // Replace with your discord server
channel: '' // ... channel
})
</script>
)");
this->installEventFilter(this);
this->page()->installEventFilter(this);
}
bool eventFilter(QObject *obj, QEvent *e)
{
qDebug() << e->type();
if( e->type() == QEvent::ChildAdded )
{
QChildEvent *ce = static_cast<QChildEvent*>(e);
ce->child()->installEventFilter(this);
}
return false;
}
};
