Most of the programming you do at the lowest level is imperative: you describe how an algorithm should work (take this value and square it; search for the first occurrence of this string and replace it; format this data this way; and so forth). With Qt Quick, your programming is largely declarative: instead of saying how you say what. For example, in C++ with Qt, we might write code like this to draw a rectangle:
QRect r(0, 0, 16, 16); QPainter p; p.setBrush(QBrush(Qt::blue)); p.drawRect(r);
This code creates a rectangle of 16 x 16 pixels, allocates a QPainter object that does the drawing, tells the painter that its brush should be colored blue, and then tells the ...
