Check[IN]Component

2 min read

Check[IN]Componentはbool変数を制御するコンポーネントです。以下のコンポーネントが標準で用意してあります。

CheckBoxComponent

check_box_component.hpp

class CheckBoxComponent : public Component
{
private:
  class CheckEvent;

public:
  CheckBoxComponent
  (
    MOD mod,
    unsigned int width,
    unsigned int height,
    unsigned char box_bg_color_R,
    unsigned char box_bg_color_G,
    unsigned char box_bg_color_B,
    unsigned char box_bg_color_A,
    spa::gui::box::POS pos,
    unsigned char check_box_bg_color_R,
    unsigned char check_box_bg_color_G,
    unsigned char check_box_bg_color_B,
    bool check,
    std::function<void(bool)> check_event
  );

	~CheckBoxComponent() = default;

	CheckBoxComponent(CheckBoxComponent const&);
	CheckBoxComponent& operator=(CheckBoxComponent const&);

	bool get();

	void configure();

  void capture();

private:
	std::unique_ptr<BoxComponent> box;
	std::unique_ptr<ClickItemComponent> click;
	std::unique_ptr<BoxImageComponent> mark;
	std::shared_ptr<bool> check;
  bool captured_check;
};

class CheckBoxComponent : public Component
{
private:
  class CheckEvent;

public:
  CheckBoxComponent
  (
    MOD mod,
    unsigned int width,
    unsigned int height,
    unsigned char box_bg_color_R,
    unsigned char box_bg_color_G,
    unsigned char box_bg_color_B,
    unsigned char box_bg_color_A,
    spa::gui::box::POS pos,
    unsigned char check_box_bg_color_R,
    unsigned char check_box_bg_color_G,
    unsigned char check_box_bg_color_B,
    bool check,
    std::function<void(bool)> check_event
  );

	~CheckBoxComponent() = default;

	CheckBoxComponent(CheckBoxComponent const&);
	CheckBoxComponent& operator=(CheckBoxComponent const&);

	bool get();

	void configure();

  void capture();

private:
	std::unique_ptr<BoxComponent> box;
	std::unique_ptr<ClickItemComponent> click;
	std::unique_ptr<BoxImageComponent> mark;
	std::shared_ptr<bool> check;
  bool captured_check;
};

box、markの引数とチェック時の関数を指定します。captured_checkはcheckが変更した場合に、recaptureを実行してキャプチャー画像を上書きしています。

check_box_component.cpp

void CheckBoxComponent::configure()
{
  attach(box.get());
  box->attach(click.get());

  if (*check)
    box->attach(mark.get());

  capture();
}

void CheckBoxComponent::capture()
{
  if (captured_check != *check)
  {
    box->recapture();
    captured_check = *check;
  }
}

void CheckBoxComponent::configure()
{
  attach(box.get());
  box->attach(click.get());

  if (*check)
    box->attach(mark.get());

  capture();
}

void CheckBoxComponent::capture()
{
  if (captured_check != *check)
  {
    box->recapture();
    captured_check = *check;
  }
}
