如何在Qt中初始化分离器手柄位置？

Question

I want to initialize the splitter handle position like the following instead of in the middle. I cannot set it in the property.

How to solve this?

Thank you for your help.

Answer 1

You should set the horizontal stretch for the two widgets in the splitter. For instance by setting the horizontal stretch of the left widget to 1 and the right widget to 2 , the right widget gets a width 2 times the left one :

leftWidget->sizePolicy().setHorizontalStretch(1);
rightWidget->sizePolicy().setHorizontalStretch(2); 

Another possible way is to use QSplitter::setSizes .

Answer 2

你可以使用QSplitter::setSizes来重新定位句柄：

ui->splitter->setSizes(QList<int>() << 100 << 200);

Answer 3

使用QSplitter::setStretchFactor(int index, int stretch) ，其中index是相应小部件的位置。
