◆ draw_overlays()

void blender::ui::AbstractTreeView::draw_overlays	(	const ARegion &	region,
		const uiBlock &	block ) const

overridevirtual

Reimplemented from blender::ui::AbstractView.

Definition at line 309 of file tree_view.cc.

◆ find_hovered()

Parameters

xy	The mouse coordinates in window space.

		IterOptions	options = IterOptions::None ) const

◆ foreach_root_item()

void blender::ui::AbstractTreeView::foreach_root_item ( ItemIterFn iter_fn ) const

Definition at line 113 of file tree_view.cc.

References blender::ui::TreeViewItemContainer::children_.

◆ is_fully_visible()

bool blender::ui::AbstractTreeView::is_fully_visible ( ) const

overridevirtual

Returns: True when everything in this view is visible, i.e. no scrolling is needed.

Reimplemented from blender::ui::AbstractView.

Definition at line 378 of file tree_view.cc.

◆ persistent_state()

std::optional< uiViewState > blender::ui::AbstractTreeView::persistent_state ( ) const

overrideprotectedvirtual

From the current view state, return certain state that will be written to files (stored in ARegion.view_states) to preserve it over UI changes and file loading. The state can be restored using persistent_state_apply().

Return an empty value if there's no state to preserve (default implementation).

Reimplemented from blender::ui::AbstractView.

Definition at line 144 of file tree_view.cc.

References state, and UI_INV_SCALE_FAC.

◆ persistent_state_apply()

void blender::ui::AbstractTreeView::persistent_state_apply ( const uiViewState & state )

overrideprotectedvirtual

Restore a view state given in state, which was created by persistent_state() for saving in files, and potentially loaded from a file.

Reimplemented from blender::ui::AbstractView.

Definition at line 162 of file tree_view.cc.

References blender::ui::padded_item_height(), round_fl_to_int(), set_default_rows(), state, and UI_SCALE_FAC.

◆ scroll()

void blender::ui::AbstractTreeView::scroll ( ViewScrollDirection direction )

overridevirtual

Reimplemented from blender::ui::AbstractView.

Definition at line 383 of file tree_view.cc.

References blender::ui::AbstractView::supports_scrolling(), and blender::ui::UP.

◆ set_default_rows()

void blender::ui::AbstractTreeView::set_default_rows ( int default_rows )

Visual feature: Define a number of item rows the view will show by default. If there are fewer items, empty dummy items will be added. These contribute to the view bounds, so the drop target of the view includes them, but they are not interactive (e.g. no mouse-hover highlight).
