QGraphicsSimpleTextItem ¶

概要 ¶

详细描述 ¶

To set the item’s text, you can either pass a QString to QGraphicsSimpleTextItem ‘s constructor, or call setText() to change the text later. To set the text fill color, call setBrush() .

The simple text item can have both a fill and an outline; setBrush() will set the text fill (i.e., text color), and setPen() sets the pen that will be used to draw the text outline. (The latter can be slow, especially for complex pens, and items with long text content.) If all you want is to draw a simple line of text, you should call setBrush() only, and leave the pen unset; QGraphicsSimpleTextItem ‘s pen is by default NoPen .

QGraphicsSimpleTextItem uses the text’s formatted size and the associated font to provide a reasonable implementation of boundingRect() , shape() ，和 contains() . You can set the font by calling setFont() .

QGraphicsSimpleText 不显示富文本；相反，可使用 QGraphicsTextItem ，其提供完整文本控制能力。
