From 1b2b35cc409525334b20339485486f7b7e4eda41 Mon Sep 17 00:00:00 2001 From: Andreas Kling Date: Mon, 24 Feb 2020 20:48:42 +0100 Subject: LibGUI: Add a MultiView widget, based on FileManager's "DirectoryView" A MultiView is a combination of ItemView, TableView and ColumnsView smashed into a single widget. You can switch between the view modes by calling MultiView::set_view_mode(). Note that MultiView inherits from StackWidget, not AbstractView. That's purely for practical reasons, although I'm not entirely sure if there would be some benefit to having it inherit from AbstractView. --- Libraries/LibGUI/Forward.h | 1 + Libraries/LibGUI/Makefile | 1 + Libraries/LibGUI/MultiView.cpp | 179 +++++++++++++++++++++++++++++++++++++++++ Libraries/LibGUI/MultiView.h | 118 +++++++++++++++++++++++++++ 4 files changed, 299 insertions(+) create mode 100644 Libraries/LibGUI/MultiView.cpp create mode 100644 Libraries/LibGUI/MultiView.h diff --git a/Libraries/LibGUI/Forward.h b/Libraries/LibGUI/Forward.h index 3fc85b72e4..ff0c6ba5c1 100644 --- a/Libraries/LibGUI/Forward.h +++ b/Libraries/LibGUI/Forward.h @@ -53,6 +53,7 @@ class Model; class ModelEditingDelegate; class ModelIndex; class MouseEvent; +class MultiView; class PaintEvent; class Painter; class ResizeCorner; diff --git a/Libraries/LibGUI/Makefile b/Libraries/LibGUI/Makefile index 3e915fbe7f..dc1bc685b8 100644 --- a/Libraries/LibGUI/Makefile +++ b/Libraries/LibGUI/Makefile @@ -40,6 +40,7 @@ OBJS = \ Model.o \ ModelIndex.o \ ModelSelection.o \ + MultiView.o \ Notification.o \ Painter.o \ ProgressBar.o \ diff --git a/Libraries/LibGUI/MultiView.cpp b/Libraries/LibGUI/MultiView.cpp new file mode 100644 index 0000000000..162a6c32c4 --- /dev/null +++ b/Libraries/LibGUI/MultiView.cpp @@ -0,0 +1,179 @@ +/* + * Copyright (c) 2018-2020, Andreas Kling + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions are met: + * + * 1.
