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 350 of file interface_template_grease_pencil_layer_tree.cc.

References 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 332 of file interface_template_grease_pencil_layer_tree.cc.

◆ 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.

◆ 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 400 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.

◆ rename()

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

inlineoverridevirtual

See AbstractViewItem::rename().

Reimplemented from blender::ui::AbstractTreeViewItem.

◆ 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.
