qt - point in rectangle test dilemma -

-

if check qt's docs on point-in-rectangle test say:

bool qrectf::contains(const qpointf & point) const

returns true if given point inside or on edge of rectangle; otherwise returns false.

this inevitably means point may belong 4 rectangles, bordering each other, @ once. there exist argument in favor of arrangement, or better rectangle contain points on edges (say, top-left)?

documentation says "edges" , not "corners". edge means line, while corner or vertex means point.

if want exclude edges, qrect version of contains() can that.

you can write own contains() , check whether point in top left corner using qrectf::topleft().

rectangles may intersect, point can contained in number of rectangles @ same time.

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
