Member Function Documentation

SIZE line_scrolling_size (   )  const

Returns the line scrolling size.

void line_scrolling_size (  int  cx, int  cy )

Sets the amount by which the window will be scrolled by "line" . If you pass negative values, a scroll to right will actually a scroll to the left; a scroll to the top will scroll to the bottom! Parameters: cx  Amount by which the window will be scrolled horizontally cy  Amount by which the window will be scrolled vertically

void page_factor (  float  xFactor, float  yFactor )

Sets the factor by which the window is scrolled by "page" . If the user does a page-scroll, the amount of scrolling will be calculated by multiplying the line scrolling size with the corresponding factor Parameters: xFactor  Factor when a horizontal page-scroll happens yFactor  Factor when a vertical page-scroll happens

float page_factor_x (   )  const

Returns the horizontal page-scroll-factor.

float page_factor_y (   )  const

Returns the vertical page-scroll-factor.

POINT scroll_pos (   )  const

Returns the current scrolling position.

void scroll_pos (  unsigned  x, unsigned  y )

Scrolls the window to position (x | y).

SIZE total_size (   )  const

Returns the total size of the window.

void total_size (  unsigned  cx, unsigned  cy )

Sets the total size of the window . If the client area of the window is smaller than the total size the scrollbars will be shown to scroll to the invisible parts of the window. Parameters: cx  cx is the horizontal size cy  cy is the vertical size

float wheel_factor (   )  const

Returns the mouse-wheel-scroll-factor.

void wheel_factor (  float  yFactor  )

Sets the factor by which the window is scrolled by "mouse-wheel" . If the user does a mouse-wheel-scroll, the amount of scrolling will be calculated by multiplying the line scrolling size with this factor Parameters: xFactor  Factor for the mouse-wheel-scroll
