Handle a file drop event

Return whether or not this widget is currently enabled

Return the fixed height (see \ref setFixedSize())

Calculates the angle of this vector in degrees in the counter trigonometric sense. 0 is to the right (3 o'clock), values increase clockwise. \return

Calculates the angle of this vector in degrees in the trigonometric sense. 0 is to the right (3 o'clock), values increase counter-clockwise. This me

Calculates the angle between this vector and ano one in degree. \param b o vector to test with. \return Returns a value between 0 and 90. */

Gets distance from ano point. Here, the vector is interpreted as a point in 2-dimensional space. \param o o vector to measure from. \return Distan

Returns squared distance from ano point. Here, the vector is interpreted as a point in 2-dimensional space. \param o o vector to measure from. \re

Creates an interpolated vector between this vector and ano vector. \param o The o vector to interpolate with. \param d Interpolation value between 0

Creates a quadratically interpolated vector between this and two o vectors. \param v2 Second vector to interpolate with. \param v3 Third vector to i

Return the current reference count

Return whether the font size is explicitly specified for this widget

Returns if this vector interpreted as a point is on a line between two o points. It is assumed that the point is on the line. \param begin Beginning
