3. Дизайн на интерфейса
(1) Прозорецът обикновено се състои от следните части: заглавна лента, лента с менюта, лента на потока (хоризонтална, вертикална), лента на състоянието и контролна лента. Операционната система Windows на Microsoft може да се нарече модел на технология за прозорци.
(2) Менюто Общо меню включва: барменю, изскачащо меню, падащо меню, меню с икони и т.н. Работата на менюто от потребителя се осъществява основно чрез щракване на мишката, допълнено от клавиатурата или сензорния екран.
(3)IconIconisacommonlyusedgraphicalinterfaceobject.Itisasmalltypewithsimplegraphicalsymbols.Itsdesignisbasedontheideaofmetaphorandsimulation.Iconscanhelpuserseasilycallfunctionsthroughtheinterface.
(4) Бутони Често срещани типове бутони включват: бутони в стила на Windows, мигащи бутони, бутони с анимирана графика, бутони Hotspot, текстови бутони, графични бутони и др.
