Class MouseGestureCapture<TRegion>

Namespace

SharpConsoleUI.Helpers

Assembly

SharpConsoleUI.dll

Sub-region gesture ownership for a control's mouse handling. On a fresh Button1 press (nothing captured) it hit-tests the region and captures it; every subsequent Button1 press/drag routes to the captured region without re-hit-testing (SGR re-sends Button1Pressed on motion, so a resent press mid- drag must NOT be treated as a fresh interaction with whatever region the cursor is now over); release ends the gesture. This is the same capture idea WindowEventDispatcher applies at the control level, applied at the sub-region level.

public sealed class MouseGestureCapture<TRegion> where TRegion : struct, Enum

Type Parameters

TRegion

The control's sub-region enum.

Properties

CapturedRegion

The region currently captured, or null if no gesture is active.

public TRegion? CapturedRegion { get; }

Property Value

TRegion?

IsCapturing

Whether a gesture is currently captured.

public bool IsCapturing { get; }

Property Value

bool

Methods

Reset()

Clears any active capture, abandoning the current gesture.

public void Reset()

Route(MouseEventArgs, Func<MouseEventArgs, TRegion>)

Routes a mouse event to the correct region for the current gesture state.

public GestureRoute<TRegion> Route(MouseEventArgs args, Func<MouseEventArgs, TRegion> hitTest)

Parameters

args MouseEventArgs

The mouse event arguments.

hitTest Func<MouseEventArgs, TRegion>

Resolves the region under the cursor. Called only on a fresh press (when nothing is captured); never re-invoked mid-gesture.

Returns

GestureRoute<TRegion>

The gesture phase and the region the event routes to.
