设置QTreeWidget头的文本的方法是什么？ [英] What is the method to set the text for a QTreeWidget's header?

问题描述

我查看了文档。

请注意，文档说它添加了一个新的列，因此如果您的视图已经有第0列，文本为1，您可以改为执行以下操作：

  if （QTreeWidgetItem * header = treeWidget-> headerItem（））{
 header-> setText（0，My Text）; 
} else {
 treeWidget-> setHeaderLabel（My Text）; 
} 
  

I've checked the documentation here and I can't seem to find a method for setting the text of a QTreeWidget's title or header.

Without setting the title QTreeWidget automatically uses the number '1' in my code. An example of what it looks like outputted is below. I'm presuming QTreeWidget has a method for this and I just can't find it.

解决方案

You're looking for setHeaderLabel.

Note that the documentation says it adds a new column, so if your view already has column 0 with text "1", you may instead have to do the following:

if(QTreeWidgetItem* header = treeWidget->headerItem()) {
  header->setText(0, "My Text");
} else {
  treeWidget->setHeaderLabel("My Text");
}
