can display and manage a grid or other 2D layout oflabelled icons. Each labelled icon is a <a href="qiconviewitem.html">QIconViewItem</a>. Items(QIconViewItems) can be added or deleted at any time; items can bemoved within the QIconView. Single or multiple items can beselected. Items can be renamed in-place. QIconView also supports<a href="#draganddrop">drag and drop</a>.<p> Each item contains a label string, a pixmap or picture (the iconitself) and optionally a sort key. The sort key is used forsorting the items and defaults to the label string. The labelstring can be displayed below or to the right of the icon (see <a href="#ItemTextPos-enum">ItemTextPos</a>).<p> The simplest way to create a QIconView is to create a QIconViewobject and create some QIconViewItems with the QIconView as theirparent, set the icon view's geometry and show it.⌨️ 快捷键说明
