Bug 211178 – [GTK4] Make popup menus work

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Adrian Perez]

Currently for popups menus windows of type GTK_WINDOW_POPUP are used,
but this is not possible with GTK4 anymore. The way to create a popup
window is using GtkPopover.

If we want to mimic GTK combo boxes, we likely would need to reimplement
parts of GtkTreePopover, which is the internal widget used as the popup
part of combo boxes. On the other hand, we may be able to put the widget
currently used inside a GtkPopover instead of inside the popup GtkWindow,
apply the same CSS classes that GtkComboBox uses, and maybe that would be
already good.

Note that ideally we want to use the same code for both GTK3 and GTK4,
as it was done recently for context menus in bug #170553 :)

This exact same line is repeated below, so I would take it out of
the “#if USE(GTK4)” guard.

Yes, but inside a GTK_CHECK_VERSION(3, 24, 0) if
