Types ¶
type BorderManager ¶
type BorderManager struct {
// contains filtered or unexported fields
}
BorderManager manages mode indicator borders on the workspace container. It creates a transparent overlay box that displays colored borders when the user enters tab mode or pane mode.
func NewBorderManager ¶
func NewBorderManager(factory layout.WidgetFactory) *BorderManager
NewBorderManager creates a border manager. It creates a border overlay widget that should be added to the workspace container.
func (*BorderManager) CurrentMode ¶
func (bm *BorderManager) CurrentMode() input.Mode
CurrentMode returns the current input mode.
func (*BorderManager) OnModeChange ¶
func (bm *BorderManager) OnModeChange(ctx context.Context, from, to input.Mode)
OnModeChange updates border visibility based on mode.
func (*BorderManager) Widget ¶
func (bm *BorderManager) Widget() layout.Widget
Widget returns the border overlay widget for adding to workspace overlay.
type Manager ¶
type Manager struct {
// contains filtered or unexported fields
}
Manager handles focus state and geometric navigation.
func NewManager ¶
func NewManager(panesUC *usecase.ManagePanesUseCase) *Manager
NewManager creates a focus manager.
func (*Manager) CollectPaneRects ¶
func (m *Manager) CollectPaneRects(ctx context.Context, provider PaneGeometryProvider) []entity.PaneRect
CollectPaneRects gathers geometry from all visible panes. For panes in stacks, uses the stack container's geometry since individual collapsed panes have no allocated size. Only visible panes are included - for stacked panes, only the active one is visible.
func (*Manager) NavigateGeometric ¶
func (m *Manager) NavigateGeometric( ctx context.Context, ws *entity.Workspace, provider PaneGeometryProvider, direction usecase.NavigateDirection, ) (*entity.PaneNode, error)
NavigateGeometric performs geometric navigation and returns the target pane. It handles stack navigation internally: when navigating up/down and the current pane is in a stack, it will try to navigate within the stack first before escaping to external panes.
type PaneGeometryProvider ¶
type PaneGeometryProvider interface {
// GetPaneIDs returns all pane IDs in the provider.
GetPaneIDs() []entity.PaneID
// GetPaneWidget returns the widget for a pane, or nil if not found.
GetPaneWidget(paneID entity.PaneID) layout.Widget
// GetStackContainerWidget returns the stack container widget for a stacked pane.
// Returns nil if the pane is not in a stack.
GetStackContainerWidget(paneID entity.PaneID) layout.Widget
// ContainerWidget returns the container widget for relative positioning.
ContainerWidget() layout.Widget
}
PaneGeometryProvider provides geometry information for panes. This interface allows the focus manager to work without direct component dependencies.
