TSplitPane class - split_pane library

Constructors

TSplitPane({Key? key, required Widget leading, required Widget trailing, Axis axis = Axis.horizontal, TSplitPaneController? controller, double initialRatio = 0.5, double? initialExtent, double minLeadingExtent = 80.0, double? maxLeadingExtent, double minTrailingExtent = 80.0, double? maxTrailingExtent, double dividerThickness = 8.0, bool showGrip = true, bool showCollapseButtons = false, bool collapsibleLeading = false, bool collapsibleTrailing = false, double collapseSnapThreshold = 40.0, ValueChanged<double>? onResized, VoidCallback? onReset}): const

Properties

axis → Axis: Split orientation: Axis.horizontal for left/right panes, Axis.vertical for top/bottom panes.
final
collapseSnapThreshold → double: Distance threshold in pixels from edge to snap pane to collapsed. Defaults to 40.0.
final
collapsibleLeading → bool: Whether dragging past collapseSnapThreshold allows snapping the leading pane to collapsed (0px). Defaults to false.
final
collapsibleTrailing → bool: Whether dragging past collapseSnapThreshold allows snapping the trailing pane to collapsed (0px). Defaults to false.
final
controller → TSplitPaneController?: Optional external controller for programmatically resizing or collapsing panes.
final
dividerThickness → double: Thickness of the interactive divider bar in pixels. Defaults to 8.0.
final
hashCode → int: The hash code for this object.
no setterinherited
initialExtent → double?: Initial pixel extent for the leading pane. If provided, overrides initialRatio.
final
initialRatio → double: Initial ratio for the leading pane (between 0.0 and 1.0). Defaults to 0.5.
final
key → Key?: Controls how one widget replaces another widget in the tree.
finalinherited
leading → Widget: The leading (left or top) widget pane.
final
maxLeadingExtent → double?: Maximum allowed pixel extent for the leading pane. If null, unbounded up to trailing minimum.
final
maxTrailingExtent → double?: Maximum allowed pixel extent for the trailing pane. If null, unbounded.
final
minLeadingExtent → double: Minimum allowed pixel extent for the leading pane. Defaults to 80.0.
final
minTrailingExtent → double: Minimum allowed pixel extent for the trailing pane. Defaults to 80.0.
final
onReset → VoidCallback?: Callback fired when the divider is double-clicked to reset.
final
onResized → ValueChanged<double>?: Callback fired whenever the split ratio changes due to user dragging or controller updates.
final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
showCollapseButtons → bool: Whether to render quick collapse/expand buttons on the divider handle. Defaults to false.
final
showGrip → bool: Whether to render a visual grip indicator in the center of the divider handle. Defaults to true.
final
trailing → Widget: The trailing (right or bottom) widget pane.
