		LayerGroup &	group )

Member Function Documentation

◆ build_context_menu()

void blender::ui::greasepencil::LayerGroupViewItem::build_context_menu	(	bContext &	C,
		uiLayout &	layout ) const

inlineoverridevirtual

Reimplemented from blender::ui::AbstractViewItem.

Definition at line 393 of file interface_template_grease_pencil_layer_tree.cc.

References C, UI_menutype_draw(), and WM_menutype_find().

◆ build_row()

void blender::ui::greasepencil::LayerGroupViewItem::build_row ( uiLayout & row )

inlineoverridevirtual

Implements blender::ui::AbstractTreeViewItem.

Definition at line 375 of file interface_template_grease_pencil_layer_tree.cc.

References uiLayout::row(), and uiLayoutSetPropDecorate().

◆ create_drag_controller()

std::unique_ptr< AbstractViewItemDragController > blender::ui::greasepencil::LayerGroupViewItem::create_drag_controller ( ) const

inlineoverridevirtual

If an item wants to support being dragged, it has to return a drag controller here. That is an object implementing AbstractViewItemDragController.

Reimplemented from blender::ui::AbstractViewItem.

Definition at line 448 of file interface_template_grease_pencil_layer_tree.cc.

References blender::ui::AbstractTreeViewItem::get_tree_view().

◆ create_drop_target()

std::unique_ptr< TreeViewItemDropTarget > blender::ui::greasepencil::LayerGroupViewItem::create_drop_target ( )

inlineoverridevirtual

Reimplemented from blender::ui::AbstractTreeViewItem.

◆ get_rename_string()

StringRef blender::ui::greasepencil::LayerGroupViewItem::get_rename_string ( ) const

inlineoverridevirtual

See AbstractViewItem::get_rename_string().

Reimplemented from blender::ui::AbstractTreeViewItem.

Definition at line 443 of file interface_template_grease_pencil_layer_tree.cc.

◆ on_activate()

void blender::ui::greasepencil::LayerGroupViewItem::on_activate ( bContext & C )

inlineoverridevirtual

Called when the view changes an item's state from inactive to active. Will only be called if the state change is triggered through the view, not through external changes. E.g. a click on an item calls it, a change in the value returned by should_be_active() to reflect an external state change does not.

Reimplemented from blender::ui::AbstractViewItem.

Definition at line 402 of file interface_template_grease_pencil_layer_tree.cc.

◆ on_collapse_change()

void blender::ui::greasepencil::LayerGroupViewItem::on_collapse_change	(	bContext &	C,
		const bool	is_collapsed )

inlineoverridevirtual

Called when the view changes an item's state from expanded to collapsed, or vice versa. Will only be called if the state change is triggered through the view, not through external changes. E.g. a click on an item calls it, a change in the value returned by should_be_collapsed() to reflect an external state change does not.

Reimplemented from blender::ui::AbstractTreeViewItem.

◆ rename()

bool blender::ui::greasepencil::LayerGroupViewItem::rename	(	const bContext &	C,
		StringRefNull	new_name )

inlineoverridevirtual

See AbstractViewItem::rename().

Reimplemented from blender::ui::AbstractTreeViewItem.

◆ set_collapsed()

bool blender::ui::greasepencil::LayerGroupViewItem::set_collapsed ( const bool collapsed )

inlineoverridevirtual

Expand or collapse this tree view item.

Note: this does not call on_collapse_change().

Returns: true when the collapsed state was changed, false otherwise.

Reimplemented from blender::ui::AbstractTreeViewItem.

Definition at line 352 of file interface_template_grease_pencil_layer_tree.cc.

References blender::ui::AbstractTreeViewItem::set_collapsed().

◆ should_be_active()

std::optional< bool > blender::ui::greasepencil::LayerGroupViewItem::should_be_active ( ) const

inlineoverridevirtual

If the result is not empty, it controls whether the item should be active or not, usually depending on the data that the view represents. Note that since this is meant to reflect externally managed state changes, on_activate() will never be called if this returns true.

Reimplemented from blender::ui::AbstractViewItem.
