Ben Wiederhake	b3e9a4e603	Libraries: Fix visibility of Object-derivative constructors ... Derivatives of Core::Object should be constructed through ClassName::construct(), to avoid handling ref-counted objects with refcount zero. Fixing the visibility means that misuses like this are more difficult.	2021-11-02 22:56:53 +01:00
Marcus Nilsson	d660e86d13	LibGUI: Implement automatic scrolling in AbstractView ... This adds automatic scrolling when dragging items in TreeViews and other widgets that inherit from AbstractView when the overloaded accepts_drag() returns true. This is implemented in FileSystemModel to allow directories and files to be dragged.	2021-09-29 23:58:55 +02:00
Marcus Nilsson	eec411c508	LibGUI: Add a AutoScroll timer to AbstractScrollableWidget ... This commit adds a timer to AbstractScrollableWidget that can be used when implementing automatic scrolling. By overriding on_automatic_scrolling_timer_fired() we can calculate the scrolling delta when dragging objects, and redraw as needed. A helper function, automatic_scroll_delta_from_position() gives us a delta that we can use to calculate speed and direction. By default m_autoscroll_threshold is 20 pixels from the edge, and gives a linear change in scroll delta.	2021-09-16 22:29:21 +02:00
