Namespace: Hex1b

Assembly: Hex1b.dll

Extension methods for building Responsive widgets. The Responsive widget displays the first child whose condition evaluates to true based on the available space from parent constraints.

Methods

Otherwise<TParent>(WidgetContext<TParent>, Func<WidgetContext<ConditionalWidget>, Hex1bWidget>)

Creates a conditional widget that always matches. Use as the last branch in a Responsive() to provide a fallback.

Parameters:

• ctx (WidgetContext<<TParent>>):
• builder (Func<ConditionalWidget>, Hex1bWidget>):

Returns: ConditionalWidget

public static ConditionalWidget Otherwise<TParent>(this WidgetContext<TParent> ctx, Func<WidgetContext<ConditionalWidget>, Hex1bWidget> builder) where TParent : Hex1bWidget

Responsive<TParent>(WidgetContext<TParent>, Func<WidgetContext<ResponsiveWidget>, ConditionalWidget[]>)

Creates a Responsive widget that displays the first child whose condition evaluates to true. Conditions receive (availableWidth, availableHeight) from the parent's layout constraints. Use collection expression syntax with When()/WhenMinWidth()/Otherwise() to define conditional branches. Example: ctx.Responsive(r => [r.WhenMinWidth(100, r => r.Text("Wide")), r.Otherwise(r => r.Text("Narrow"))])

Parameters:

• ctx (WidgetContext<<TParent>>):
• builder (Func<ResponsiveWidget>, ConditionalWidget[]>):

Returns: ResponsiveWidget

public static ResponsiveWidget Responsive<TParent>(this WidgetContext<TParent> ctx, Func<WidgetContext<ResponsiveWidget>, ConditionalWidget[]> builder) where TParent : Hex1bWidget

When<TParent>(WidgetContext<TParent>, Func<int, int, bool>, Func<WidgetContext<ConditionalWidget>, Hex1bWidget>)

Creates a conditional widget that wraps content with a size-based condition. The condition receives (availableWidth, availableHeight) from the parent's layout constraints. Use inside a Responsive() builder to create conditional branches.

Parameters:

• ctx (WidgetContext<<TParent>>):
• condition (Func<Int32, Int32, Boolean>):
• builder (Func<ConditionalWidget>, Hex1bWidget>):

Returns: ConditionalWidget

public static ConditionalWidget When<TParent>(this WidgetContext<TParent> ctx, Func<int, int, bool> condition, Func<WidgetContext<ConditionalWidget>, Hex1bWidget> builder) where TParent : Hex1bWidget

WhenMinWidth<TParent>(WidgetContext<TParent>, int, Func<WidgetContext<ConditionalWidget>, Hex1bWidget>)

Creates a conditional widget with a minimum width requirement. The content is displayed when availableWidth >= minWidth.

Parameters:

• ctx (WidgetContext<<TParent>>):
• minWidth (Int32):
• builder (Func<ConditionalWidget>, Hex1bWidget>):

Returns: ConditionalWidget

public static ConditionalWidget WhenMinWidth<TParent>(this WidgetContext<TParent> ctx, int minWidth, Func<WidgetContext<ConditionalWidget>, Hex1bWidget> builder) where TParent : Hex1bWidget

WhenWidth<TParent>(WidgetContext<TParent>, Func<int, bool>, Func<WidgetContext<ConditionalWidget>, Hex1bWidget>)

Creates a conditional widget with a width-only condition. Convenience overload for common width-based responsive layouts.

Parameters:

• ctx (WidgetContext<<TParent>>):
• widthCondition (Func<Int32, Boolean>):
• builder (Func<ConditionalWidget>, Hex1bWidget>):

Returns: ConditionalWidget

public static ConditionalWidget WhenWidth<TParent>(this WidgetContext<TParent> ctx, Func<int, bool> widthCondition, Func<WidgetContext<ConditionalWidget>, Hex1bWidget> builder) where TParent : Hex1bWidget
