How to vertically align text and image above a JRadioButton?

问题 Is it possible to align both the text and image above the JRadioButton icon? Edit - Well, apparently setting the icon in the constructor actually replaces the default JRadioButton icon, which I wasn't expecting. Looks like I may have to use two separate components and throw them into the same container. 回答1: This will set the text above the JRadioButton: radiobutton.setHorizontalTextPosition(SwingConstants.CENTER); radiobutton.setVerticalTextPosition(JRadioButton.TOP); And yes, using the

Check which jRadioButtons have been selected if they have been created in a loop

痴心易碎 提交于 2019-12-11 13:15:11
问题 I have a loop that creates rows, where each row has another loop to create 6 JRadioButtons. Only one JRadioButton can be selected from each row (as it should be), but I'm finding it difficult to use Action Listeners to check whether the correct JRadioButton has been selected from each row, and then change an empty JLabel to show "correct", but I think that will be simple once I've managed the first part. This is the relevant code I'm working with: //loop for making flow layout for each line

Swing: Resizing RadioButton

拜拜、爱过 提交于 2019-12-11 08:40:17
问题 I need to implement font size switching in my app. But when I increase font's size RadioButtons remain same size and on small screen with high resolution my customer just can't hit it easily. Is there a way to resize RadioButton's round thing programmatically without diging into L&F and redrawing Icons manually (it's complicated since app targets multiple platforms with different UIs and each of them must have 7 icons). Perfect solution could look like this: Extraction of native UI icon.
