Introduction to flowlayout of Java swing component layout manager

This article describes the flowlayout of the Java swing component layout manager with examples. It is shared for your reference as follows:

Flowlayout should be the simplest and most basic one in swing layout manager learning. The so-called flow type means that the internal controls are arranged horizontally from front to back like water flow until they reach the width of the container and jump to the second line. Since it is arranged horizontally, there are three basic alignments: Center, left and right. However, flowlayout also provides two alignments: leading, which indicates that the control corresponds to the beginning edge of the container direction; tracking, which indicates that the control corresponds to the end edge of the container direction. Setalignment (int align) is used to set the alignment. In general, leading is left aligned and tracking is right aligned. In addition, flowlayout can also set the spacing between internal controls and between internal controls and containers. Sethgap (int hgap) is used to specify the horizontal spacing; Setvgap (int vgap) is used to specify the vertical spacing.

Common methods of flowlayout are as follows:

The test cases are as follows:

The operation effect is as follows:
