A must-see for PyQt beginners: Detailed explanation of the use of Spacers components in Qt Designer
In PyQt, Qt Designer is a very convenient tool that can help us design beautiful and practical interfaces. Among them, the Spacers component is a very important component that can help us adjust the spacing and layout between controls. Next let us learn how to use Spacers.
- What are Spacers?
Spacers (spacer) is a special control that can be added by inserting a Spacer Item in Qt Designer. Spacers are not displayed, they are just placeholders used to occupy space, which can affect the layout method and the spacing between controls.
- Types of Spacers
In Qt Designer, there are three types of Spacers: Horizontal Spacer, Vertical Spacer and Grid Spacer.
Horizontal Spacer and Vertical Spacer are used to control the spacing and position between controls, and they can be stretched both horizontally and vertically. Grid Spacer is mainly used in grid layout, which can help us adjust the spacing and width between rows and columns.
