◆ build_context_menu()

uiLayout & layout ) const

◆ build_row()

◆ 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.

◆ 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.

◆ 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.

◆ rename()

StringRefNull new_name )
inlineoverridevirtual

◆ 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.

◆ 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.

Definition at line 394 of file interface_template_grease_pencil_layer_tree.cc.

◆ should_be_collapsed()

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

If the result is not empty, it controls whether the item should be collapsed or not, usually depending on the data that the view represents.

Reimplemented from blender::ui::AbstractTreeViewItem.

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

◆ supports_renaming()

bool blender::ui::greasepencil::LayerGroupViewItem::supports_renaming ( ) const
inlineoverridevirtual

Queries if the view item supports renaming in principle. Renaming may still fail, e.g. if another item is already being renamed.

Reimplemented from blender::ui::AbstractViewItem.
