How to auto-adjust font size of multiple JLabel based on container size in a smooth way?

由 痞子三分冷 提交于 2019-11-27 06:57:10
问题 I need to resize the font of multiple JLabel based on the scaling factor used to resize the container. To do this, I am setting the font of each JLabel to null so that they take the font of the container. It works, but it also produces strange results. To be specific, the text seems to "lag" behind the container and sometimes it gets even truncated. I would like to avoid this behavior. Any idea how? Example code simulating the behavior: import java.awt.BorderLayout; import java.awt.Color;

Now I want to rotate the image on screen to arbitrary angles. I found something about Graphics2D but i don't find the way to do that. Since solutions that I found doesn't work or I don't understand them, I'm interested in any solution to rotate the ImageIcon or the JLabel. Since I'm positioning the image
