From 01ab36ebc1c43764b8bfb4c41f4c837a3b8757cb Mon Sep 17 00:00:00 2001 From: Julian Eisel Date: Wed, 24 Nov 2021 17:29:43 +0100 Subject: Asset Browser: Support dragging catalogs into top level This was an oversight when I added catalog drag & drop support. I forgot to add this for dragging catalogs into the top level by dragging into to the "All" item as well. This made the drag & drop support rather broken because it wouldn't work for a basic case. --- .../editors/space_file/asset_catalog_tree_view.cc | 109 ++++++++++++++++++--- 1 file changed, 94 insertions(+), 15 deletions(-) (limited to 'source/blender/editors/space_file') diff --git a/source/blender/editors/space_file/asset_catalog_tree_view.cc b/source/blender/editors/space_file/asset_catalog_tree_view.cc index 41559278910..51928fa7c23 100644 --- a/source/blender/editors/space_file/asset_catalog_tree_view.cc +++ b/source/blender/editors/space_file/asset_catalog_tree_view.cc @@ -52,6 +52,8 @@ using namespace blender::bke; namespace blender::ed::asset_browser { +class AssetCatalogTreeViewAllItem; + class AssetCatalogTreeView : public ui::AbstractTreeView { ::AssetLibrary *asset_library_; /** The asset catalog tree this tree-view represents. */ @@ -61,6 +63,7 @@ class AssetCatalogTreeView : public ui::AbstractTreeView { friend class AssetCatalogTreeViewItem; friend class AssetCatalogDropController; + friend class AssetCatalogTreeViewAllItem; public: AssetCatalogTreeView(::AssetLibrary *library, @@ -69,6 +72,8 @@ class AssetCatalogTreeView : public ui::AbstractTreeView { void build_tree() override; + void activate_catalog_by_id(CatalogID catalog_id); + private: ui::BasicTreeViewItem &build_catalog_items_recursive(ui::TreeViewItemContainer &view_parent_item, AssetCatalogTreeItem &catalog); @@ -122,16 +127,22 @@ class AssetCatalogDropController : public ui::AbstractTreeViewItemDropController bool on_drop(const wmDrag &drag) override; ::AssetLibrary &get_asset_library() const; - AssetCatalog *get_drag_catalog(const wmDrag &drag) const; + static AssetCatalog *get_drag_catalog(const wmDrag &drag, const ::AssetLibrary &asset_library); static bool has_droppable_asset(const wmDrag &drag, const char **r_disabled_hint); static bool drop_assets_into_catalog(const AssetCatalogTreeView &tree_view, const wmDrag &drag, CatalogID catalog_id, StringRefNull simple_name = ""); + /** + * \param drop_catalog_id: Can be unset to drop into the root level of the tree. + */ + static bool drop_asset_catalog_into_catalog( + const wmDrag &drag, + AssetCatalogTreeView &tree_view, + const std::optional drop_catalog_id = std::nullopt); private: - bool drop_asset_catalog_into_catalog(const wmDrag &drag); std::string drop_tooltip_asset_list(const wmDrag &drag) const; std::string drop_tooltip_asset_catalog(const wmDrag &drag) const; }; @@ -142,6 +153,16 @@ class AssetCatalogTreeViewAllItem : public ui::BasicTreeViewItem { using BasicTreeViewItem::BasicTreeViewItem; void build_row(uiLayout &row) override; + + struct DropController : public ui::AbstractTreeViewItemDropController { + DropController(AssetCatalogTreeView &tree_view); + + bool can_drop(const wmDrag &drag, const char **r_disabled_hint) const override; + std::string drop_tooltip(const wmDrag &drag) const override; + bool on_drop(const wmDrag &drag) override; + }; + + std::unique_ptr create_drop_controller() const override; }; class AssetCatalogTreeViewUnassignedItem : public ui::BasicTreeViewItem { @@ -228,6 +249,13 @@ void AssetCatalogTreeView::add_unassigned_item() [params]() { return params->asset_catalog_visibility == FILE_SHOW_ASSETS_WITHOUT_CATALOG; }); } +void AssetCatalogTreeView::activate_catalog_by_id(CatalogID catalog_id) +{ + params_->asset_catalog_visibility = FILE_SHOW_ASSETS_FROM_CATALOG; + params_->catalog_id = catalog_id; + WM_main_add_notifier(NC_SPACE | ND_SPACE_ASSET_PARAMS, nullptr); +} + bool AssetCatalogTreeView::is_active_catalog(CatalogID catalog_id) const { return (params_->asset_catalog_visibility == FILE_SHOW_ASSETS_FROM_CATALOG) && @@ -243,11 +271,8 @@ AssetCatalogTreeViewItem::AssetCatalogTreeViewItem(AssetCatalogTreeItem *catalog void AssetCatalogTreeViewItem::on_activate() { - const AssetCatalogTreeView &tree_view = static_cast( - get_tree_view()); - tree_view.params_->asset_catalog_visibility = FILE_SHOW_ASSETS_FROM_CATALOG; - tree_view.params_->catalog_id = catalog_item_.get_catalog_id(); - WM_main_add_notifier(NC_SPACE | ND_SPACE_ASSET_PARAMS, nullptr); + AssetCatalogTreeView &tree_view = static_cast(get_tree_view()); + tree_view.activate_catalog_by_id(catalog_item_.get_catalog_id()); } void AssetCatalogTreeViewItem::build_row(uiLayout &row) @@ -344,7 +369,7 @@ AssetCatalogDropController::AssetCatalogDropController(AssetCatalogTreeView &tre bool AssetCatalogDropController::can_drop(const wmDrag &drag, const char **r_disabled_hint) const { if (drag.type == WM_DRAG_ASSET_CATALOG) { - const AssetCatalog *drag_catalog = get_drag_catalog(drag); + const AssetCatalog *drag_catalog = get_drag_catalog(drag, get_asset_library()); /* Note: Technically it's not an issue to allow this (the catalog will just receive a new * path and the catalog system will generate missing parents from the path).
