inheritance - employee - manager class diagram, representing additional constraints on manager entity -


i come er background , shifting uml diagrams. constructing uml diagram real work scenario. 1 of class diagram constructing employee - manager class diagram, manager employee. classic uml diagram has been around ages , constructed below

classic employee-manager class diagram

however there things manager can employee cannot, manager can pay wages (and to) employees working under him/her. solution situation reconstruct class diagram this

employee-manager extended class diagram

i creating specialized class manager , represent relationship third entity. ?

there lot of possible types of relationships between employee , manager. expect every manager employee. true? interim manager instance employee? or subcontractor? or project manager organization? same questions can applied employees.

therefor classical relationship between employee , manager in many cases incorrect. employee have several roles in 1 organization. happens in high schools or colleges, persons have educational contracts in different departments. 1 employee having different managers @ different hours of day.

has manager several employees in department or set of contracts? describe manager implementation of function , being employee status having valid contract within organization? organization might have 100 employees, 75 fte , 10 managers of 2 work different organizations.

the answer question therefor: chance model correct imo quite small. relationship more complex model can describe.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
