◆ adjust_to_screen()

OCTGUI_API void adjust_to_screen ( QRect &  actual_geometry,
const QRect &  default_geometry 
)

Adjust geometry to be completely on a screen

Parameters
actual_geometryQRect with actual widget geometry; this is changed to the updated geometry which is on the screen.
default_geometrythe default geometry that is used in case the actual geometry os on no available screen.

◆ get_screen_geometry()

OCTGUI_API void get_screen_geometry ( int &  width,
int &  height 
)

Get the screen geometry of the actual screen.

Parameters
widthinteger variable for storing the screen width
heightinteger variable for storing the screen height

◆ interpolate_color()

OCTGUI_API QColor interpolate_color ( const QColor &  col1,
const QColor &  col2,
double  fs,
double  fv 
)

Deterimine an alternative color to col1 with less contrast to col2. The HSV representation of the new color is calculated by

\begin{eqnarray*} H &=& H_1\\ S &=& f_s S_1\\ V &=& V_1 + f_s (V_2 - V_1) \end{eqnarray*}

Parameters
col1Base color to which the alternative has to be computed
col2Color to which the the new color should have less contrast
fsFactor for changing the saturation $(0\ldots\infty)$
fvFactor for interpolating the brightness $(0\ldots 1)$. For 0, $V = V_1$ and for 1, $V = V_2$.
Returns
New color as QColor
