Example

auto btn = std::make_shared<Button>("Increment");
btn->SetOnPressed([&counter]() {
    counter++;
    widget->MarkNeedsBuild();
  })
  .SetFontSize(16.0F)
  .SetBackgroundColor({.r = 33, .g = 150, .b = 243, .a = 255})
  .SetTextColor({.r = 255, .g = 255, .b = 255, .a = 255})
  .SetBorderRadius(6.0F);

Behavior

• OnPointerDown: Sets is_pressed_ = true if the press is within bounds.
• OnPointerUp: Invokes on_pressed_ if the release is within bounds and the button was pressed.
• The pressed widget is tracked via std::weak_ptr to avoid dangling references after rebuilds.
