Ifayile yokuguqulwa komfanekiso kwiJava: Isikhokelo esiBanzi

Ngaba ukhe wafuna ukuguqula ifayile ibe yifomati yomfanekiso, kodwa ubungaqinisekanga ukuba uyenza njani na kwiJava? Ungajongeli phambili, kuba kweli nqaku, siza kugubungela yonke into oyifunayo malunga nokuguqulwa kwefayile kumfanekiso usebenzisa iJava. Siza kuqala ngentshayelelo yokuba yintoni ingxaki kwaye siqhubele phambili sixoxa ngesona sisombululo sifanelekileyo. Emva koko, siya kuchaza ikhowudi inyathelo ngenyathelo ukuze ukwazi ukulandela kwaye uqonde inkqubo. Ekugqibeleni, siza kuphonononga iinkcukacha ezingakumbi eziyelelene nengxaki, amathala eencwadi, kunye nemisebenzi ebandakanyekayo. Ngoko masingene kanye phakathi.

Ehlabathini lewebhu kunye nezicelo zeselfowuni, ukusetyenziswa kwamaqhosha e icon kuye kwanda ukuthandwa kwaye kubalulekile ekuboneleleni ngamava afanelekileyo omsebenzisi. Amaqhosha e-Icon abonisa izenzo okanye imiyalelo yomzobo, evumela abasebenzisi ukuba bakhangele kwaye basebenzisane nesicelo ngendlela eqondakalayo nenomtsalane. Njengomphuhlisi weJava, ukuqonda ukuba uwenza njani kwaye uphumeze amaqhosha e icon kwizicelo zakho kubalulekile. Kule nqaku, siya kukhangela inkqubo yokudala iqhosha le icon, sixoxe ngeelayibrari ezifanelekileyo kunye nemisebenzi, kwaye sinikeze isikhokelo sesinyathelo ngesinyathelo malunga nendlela yokubhala ikhowudi yeJava ngokukodwa kule njongo.

Ukuze wenze iqhosha le icon eliguquguqukayo nelinomtsalane, kufuneka siqale silungise izinto zalo eziphambili. Iqhosha le-icon lidla ngokuqulatha umfanekiso (umfanekiso) omele isenzo, esikhatshwa yikhowudi eyenza intshukumo ehambelanayo xa iqhosha licofa. Kukho amathala eencwadi aliqela esinokuwasebenzisa; kunjalo, kweli nqaku, siya kugxila ekusebenziseni Java Swing kunye neklasi ImageIcon.

IJava Swing lithala leencwadi elisetyenziswa ngokubanzi ukwenza ujongano lomsebenzisi womzobo (GUIs) kwizicelo zeJava. Enye yamacandelo ayo amaninzi yiklasi ye-JButton, eyenza lula ukudala kunye nokwenza ngokwezifiso amaqhosha. I UmfanekisoIcon iklasi, kwelinye icala, ivumela abaphuhlisi ukuba badibanise ngokulula imifanekiso kwizicelo zabo.

Ukwenza iqhosha le-Icon ngeJava Swing kunye ne-IconIcon

Ukwenza iqhosha le icon usebenzisa iJava Swing kunye neklasi ye-IconIcon, landela la manyathelo:

1. Thatha ngaphandle amathala eencwadi ayimfuneko:

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

2. Yenza iklasi eyandisa iklasi ye-JFrame kwaye iphumeze i-ActionListener interface:

public class IconButtonExample extends JFrame implements ActionListener {
    // Your code here...
}

3. Ngaphakathi kweklasi, chaza kwaye uqalise iinguqu eziyimfuneko, njenge JButton kunye ne-ImageIcon izinto:

private JButton btnIcon;
private ImageIcon imgIcon;

4. Yenza kwaye uqwalasele iJFrame, JButton, kunye neMifanekisoIcon iimeko:

public IconButtonExample() {
    // Initialize the ImageIcon instance with the desired image
    imgIcon = new ImageIcon("path/to/icon/image.png");
    // Initialize the JButton instance with the ImageIcon
    btnIcon = new JButton(imgIcon);
    // Add the ActionListener to the JButton
    btnIcon.addActionListener(this);
    // Configure the JFrame
    setLayout(new FlowLayout());
    setTitle("Icon Button Example");
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    // Add the JButton to the JFrame
    add(btnIcon);
    pack();
    setVisible(true);
}

5. Sebenzisa indlela ye-actionPerformed esuka kwi-ActionListener interface:

public void actionPerformed(ActionEvent e) {
    if (e.getSource() == btnIcon) {
        // Perform the desired action
    }
}

6. Yenza eyona ndlela iphambili eqhuba isicelo:

public static void main(String[] args) {
    SwingUtilities.invokeLater(() -> new IconButtonExample());
}

Nje ukuba la manyathelo egqityiwe, uya kuba neqhosha le-icon esebenzayo kwisicelo sakho seJava, usebenzisa zombini iilayibrari ze-Swing kunye ne-ImageIcon.

Kwihlabathi lanamhlanje, iteknoloji kunye nefashoni zihamba kunye. Ngelixa abathanda ifashoni belandela iindlela zamva nje, abaphuhlisi bahlala besebenza ekuyileni usetyenziso kunye neewebhusayithi eziphakamisa amava omsebenzisi. Enye into ethandwa kakhulu yimo yesikrini esigcweleyo. Kweli nqaku, siza kuphonononga inkqubo yokwenza ukusilela kwesikrini esigcweleyo kwizicelo zeJava, sijonge kwizitayile, inkangeleko, kunye nentsingiselo yeendlela zokuhamba kunye nefashoni ngokubanzi, kwaye sifunde nangembali yeendlela ezahlukeneyo zokunxiba kunye nemibala.

Ukwenza ukusilela kwesikrini esigcweleyo kwiJava, i Isikrini esiphelele ithala leencwadi liyasetyenziswa. Inika isisombululo esilula nesisebenzayo kule ngxaki. Iklasi yesikrini esigcweleyo sinemisebenzi ebalulekileyo enceda abaphuhlisi ukuba baphumeze imo yesikrini esipheleleyo kwizicelo zabo. Ukuqalisa, makhe siqonde inkcazo ngenyathelo ngenyathelo lekhowudi ebandakanyekayo ekwenzeni lo msebenzi.

import java.awt.*;
import javax.swing.*;

public class FullscreenExample {
  public static void main(String[] args) {
    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    
    GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment();
    GraphicsDevice device = env.getDefaultScreenDevice();
    
    // Fullscreen mode is enabled
    device.setFullScreenWindow(frame);
    
    frame.add(new JLabel("Full screen mode enabled!"));
    frame.validate();
  }
}

Kwisiqwengana sekhowudi engentla, siqala ngokungenisa iilayibrari eziyimfuneko kwaye senze i-JFrame. Emva koko sifumana iimeko zeGraphicsEnvironment kunye neGraphicsDevice ezisetyenziselwa ukunxibelelana nesetingi yemizobo. Ekugqibeleni, senza imo yesikrini esigcweleyo sisebenzisa i setFullScreenWindow() indlela yomzekelo weGraphicsDevice.

Kwihlabathi lenkqubo yeJava kunye nefashoni, iiTableViews zihlala zidlala indima ebalulekileyo ekudaleni ujongano olubonakalayo kunye nolungelelwaniso olufanelekileyo lwabasebenzisi, ngakumbi kwiinkqubo ezifuna ukubonisa inani elikhulu ledatha. Ngokufana nelizwe lefashoni, apho iintsingiselo kunye nezimbo zitshintsha ngokuhamba kwexesha, abaphuhlisi ngamanye amaxesha kufuneka basuse yonke imiqolo kwiTableView ukulungiselela iimfuno eziguqukayo. Kweli nqaku, siza kukhangela kwiindlela zokususa yonke imiqolo kwiTableView usebenzisa iJava, ukubonelela ngengcaciso ecacileyo yekhowudi kunye nokuxoxa ngamathala eencwadi kunye nemisebenzi. Ke, masihambe indlela yeenqwelomoya yenkqubo yeJava, ifashoni, kunye nesimbo!
