问题描述
我知道您可以使用以下各项设置每个项目的对齐方式:
I know you can set the alignment for each item using:
TableWidget->item(0,0)->setTextAlignment(Qt::AlignLeft);
但是我想为所有单元格设置默认对齐方式,而不必设置每当我创建一个新项目时,
However I would like to set a default alignment for all the cells in order to do not have to set it every time I create a new item. Is it possible?
推荐答案
是可以的。但是您需要了解,您不是在修改表窗口小部件的属性,而是在修改表窗口小部件项的属性。首先创建自己的项目,然后根据需要进行设置
Yes it is possible. But you need to understand you are not modifying a property of the table widget, but a property of the table widget item. First create your own item, and set it up as you want
QTableWidgetItem * protoitem = new QTableWidgetItem();
protoitem->setTextAlignment(Qt::AlignLeft);
etc...
然后每次您想要创建新项目而不是使用您使用的构造函数
Then each time you want to create a new item rather than using the constructor you use
QTableWidgetItem * newitem = protoitem->clone();
tableWidget->setItem(0,0, newitem);
克隆(未经测试)的另一种方法是
Another alternative to clone (untested) is to set a prototype on your tablewidget
QTableWidget::setItemPrototype ( const QTableWidgetItem * item )
如果您使用的是最后一个比较合适Ui或该项目是否可编辑。
This last one can be more appropriate if you are using a Ui or if the item is editable.
