Qt learning path (41): QTableWidget

Today's QTableWidget is the last items class type. However, this is not the end of model-view, because we are still only exposed to the simplest model-view encapsulation class, more complex and powerful model-view applications have not yet seen it! QTableWidget is also very convenient to use and is not more complicated than the previous two. The result we run is like this: 650) this. width = 650; "onclick = 'window. open (" http://blog.51cto.com/viewpic.php?

First create a QTableWidget object, and then set the number of columns and the number of rows. Next, we use a QStringList to set the title of each column. Then, call the addItem () function. The first two parameters of this function are row and column col, and the third parameter is used to construct a QTableWidgetItem object, qt will place this object in the cell in the col column of the row. Note that the rows and columns start from 0.
