I can not figure out one problem, I have a JTextArea form in my application and a JScrollPane attached to it. But I donβt know how to make a working scrolling, when the JtextArea field is completely filled with text, it starts to increase its vertical size and enters the progress bar and buttons located below. I would like to correct this situation.
Here is the code
package main.java.view; import javax.swing.*; import java.awt.*; public class ShopQueueGUIApp { public static final int W_WIDTH = 540; public static final int W_HEIGHT = 500; public static void main(String[] args) { JFrame mainForm = new JFrame("Queue Shop v0.3 alpha"); mainForm.setSize(W_WIDTH,W_HEIGHT); // ΡΠ°Π·ΠΌΠ΅Ρ ΠΎΠΊΠ½Π° mainForm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // Π·Π°ΠΊΡΡΠ²Π°ΡΡ ΠΏΡΠΈΠ»ΠΎΠΆΠ΅Π½ΠΈΠ΅ Π½Π°ΠΆΠ°ΡΠΈΠ΅ΠΌ ΠΊΡΠ΅ΡΡΠΈΠΊΠ° mainForm.setLocationRelativeTo(null); // ΡΠ°ΡΠΏΠΎΠ»ΠΎΠΆΠΈΡΡ ΠΎΠΊΠ½ΠΎ ΠΏΠΎ ΡΠ΅Π½ΡΡΡ ΡΠΊΡΠ°Π½Π° mainForm.setResizable(false); // Π·Π°ΠΏΡΠ΅ΡΠΈΡΡ ΠΈΠ·ΠΌΠ΅Π½Π΅Π½ΠΈΠ΅ ΡΠ°Π·ΠΌΠ΅ΡΠΎΠ² ΠΎΠΊΠ½Π° mainForm.setLayout(new GridBagLayout()); // Π‘Π»ΠΎΠΉ // Π’Π΅ΠΊΡΡΠΎΠ²Π°Ρ ΠΈΠ½ΡΠΎΡΠΌΠ°ΡΠΈΡ ΠΎ ΡΠ°Π±ΠΎΡΠ΅ ΠΏΡΠΈΠ»ΠΎΠΆΠ΅Π½ΠΈΡ //-------------------------------------------------------------- JLabel infoLabel = new JLabel("ΠΠ°Π½Π½Π°Ρ ΠΏΡΠΎΠ³ΡΠ°ΠΌΠΌΠ° ΠΌΠΎΠ΄Π΅Π»ΠΈΡΡΠ΅Ρ"); JLabel infoLabel2 = new JLabel("ΠΎΡΠ΅ΡΠ΅Π΄Ρ ΠΏΠΎΠΊΡΠΏΠ°ΡΠ΅Π»Π΅ΠΉ Π² ΠΊΠ°ΡΡΡ"); JLabel infoLabel3 = new JLabel("ΠΌΠ°Π³Π°Π·ΠΈΠ½Π°."); JLabel infoLabel4 = new JLabel("ΠΠ°ΠΆΠ΄ΡΡ ΠΌΠΈΠ½ΡΡΡ Π·Π°Ρ
