How to initialize the splitter handle position in Qt?

问题

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.

You can use QSplitter::setSizes in this why to reposition the handle:

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

回答2:

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.

Use QSplitter::setStretchFactor(int index, int stretch) where index is the position of the respective widget.
