Function documentation

void UTFWin::ScrollbarDrawable::Paint(UIRenderer* pRenderer, const Math::Rectangle& area, const RenderParams& params) override

Paints this drawable onto the given UIRenderer.

Parameters
pRenderer The UIRenderer where this must be drawn.
area The area of the window to draw.
params RenderParams that contain additional information (e.g. what image do draw, the current state, etc).

bool UTFWin::ScrollbarDrawable::IsColliding(const Math::Rectangle& area, const Math::Point& point, RenderParams& params) override

Tells whether the point specified is colliding in this drawable or not.

Parameters
area The area of the window that is using this drawable.
point The Point to check whether it collides or not. Its coordinates are relative to the window position.
params Additional information, probably unused.

This method is useful for drawables that use hitmasks.

bool UTFWin::ScrollbarDrawable::GetDimensions(Dimensions& dst, int state, int index) override

Used to get the dimensions of an image contained in this drawable.

Parameters
dst out The Dimensions where the result must be written.
state The current state flags of the window.
index The index of the image whose dimensions must be returned.
Returns True if the dimensions were got, false otherwise.

bool UTFWin::ScrollbarDrawable::UseCollision(uint32_t type, bool& dst) override

Tells whether the collision of a window should be handled by this drawable or not.

Parameters
type The type, usually kDefaultCollisionType.
dst out If the collision type is supported, whether it must be handled by this drawable or not.
Returns True if the collision type is supported (even if it's not handled by this drawable), false otherwise.

void UTFWin::ScrollbarDrawable::SetImage(int index, Image* pImage) override

Set the images used by this drawable.

Parameters
index The index of the image to set.
pImage The image.

The index is one of the AbstractScrollbarDrawable::kImage... values.
