JTextPane Syntax Highlight

Thu, 26 Mar 2015 20:17:23 GMT

Hej alle sammen, jeg fandt en kode som laver en glimrende syntax highlighter kode. Men mit problem er at lige s� snart jeg bruger funktionen

Java kode

 area.setText("if (int i = 0)");

s� opdatere den ikke automatisk. Den highlighter kun teksten n�r jeg skriver den.

Jeg bruger JTextPane og koden er her:

Mixer JavaFX og Swing problemer (Linje numre)

Fri, 14 Nov 2014 19:01:14 GMT

Hej alle sammen jeg pr�ver at mixe JavaFX og Swing med JTextPane (Text Editor) og JTextArea (Linje numre) hvilket g�r nogenlunde.

Jeg bruger ogs� tabs (JavaFX tabs), til at holde p� flere Text Editor og Linje Numre... Men mit problem er at Linje numre kun virker i en af de tabs jeg har �bne. S� de andre tabs linje numre ikke virker her er min kode :

Tabs

Java kode

 public static TabPane pane;
     public static ArrayList<Tab> tabList;
     public static ArrayList<ScrollPane> scrollist;
     public static int SelectedIndex;
 
     public static void setTab() {
         pane = new TabPane();
         tabList = new ArrayList<Tab>();
         scrollist = new ArrayList<>();
         
         addTab("Hej Verden");
         addTab("Hej Verden 1");
         addTab("Hej Verden 2");
 
         pane.getSelectionModel().selectedItemProperty().addListener((ObservableValue<? extends Tab> ov, Tab t, Tab t1) -> {
             SelectedIndex = pane.getSelectionModel().getSelectedIndex();
             System.out.println(SelectedIndex);
         });
     }
 
     public static void addTab(String title) {
         SwingNode swingNode = new SwingNode();
         createSwingContent(swingNode);
 
         Tab tab = new Tab(title);
         tab.setContent(swingNode);
         
         pane.getTabs().add(tab);
         tabList.add(tab);
         
     }
 
     private static void createSwingContent(SwingNode swingNode) {
         SwingUtilities.invokeLater(new Runnable() {
             @Override
             public void run() {
                 JScrollPane jsp = new JScrollPane();
                 ArrayList<JScrollPane> jsplist = new ArrayList<>();
                 TextArea area = new TextArea();
                 
                 jsp.getViewport().add(area.editor.get(SelectedIndex));
                 jsp.setRowHeaderView(area.Lines.get(SelectedIndex));
                 jsplist.add(jsp);
                 swingNode.setContent(jsplist.get(SelectedIndex));
             }
         });
     }

TextArea:

Java kode

 private static JTextPane pane;
     private static JTextArea line;
     public ArrayList<JTextPane> editor;
     public ArrayList<JTextArea> Lines;
     public TextArea() {
         editor = new ArrayList<JTextPane>();
         Lines = new ArrayList<>();
         pane = new JTextPane();
         line = new JTextArea("1");
         line.setEditable(false);
         line.setBackground(Color.black);
         line.setForeground(Color.orange);
         pane.setBorder(null);
         
         pane.getDocument().addDocumentListener(new DocumentListener() {
             public String getText(){
                 int caretPosition = pane.getDocument().getLength();
                 Element root = pane.getDocument().getDefaultRootElement();
                 String text = "1" + System.getProperty("line.separator");
                 for(int i = 2; i < root.getElementIndex( caretPosition ) + 2; i++){
                     text += i + System.getProperty("line.separator");
                 }
                 return text;
             }
             
             @Override
             public void removeUpdate(DocumentEvent e) {
                 line.setText(getText());
             }
             
             @Override
             public void insertUpdate(DocumentEvent e) {
                 line.setText(getText());
             }
             
             @Override
             public void changedUpdate(DocumentEvent e) {
                 line.setText(getText());
             }
         });

Java Swing JFileChooser f� fil til at ende med valgte fil type fra file extension

Thu, 17 Jul 2014 16:48:13 GMT

Hej alle sammen, jeg har f�et det problem at jeg ikke kan f� mine filer til at ende med den valgte fil type n�r den skal gemmes.

Foreksempel : Jeg v�lger i JFileChooser at det skal v�re en .html fil (og ikke bare alle fil typer). Og n�r jeg s� gemmer filen ender den ikke med .html men med .asm eller ikke noget.

Nogen som vil v�re s�de at hj�lpe med det?

Multi Page JTextarea eller JTextpane

Mon, 09 Dec 2013 22:02:18 GMT

Hej Udviklere,

Jeg har s�gt og s�gt, og kan ikke rigtigt finde en l�sning til hvordan man kan lave en text control om til at have flere sidder. Det t�tteste jeg er kommet p�, er ved at benytte javaFX paginationControl. Dog er dette ikke helt den effekt, jeg leder efter. Ville gerne kunne lave noget i stil med Office Word, hvor man har flere sidder, der kan scrolles ned igennem.

Min umildbare tanke var at jeg kunne lave en ArrayList af JTextarea, og inds�tte disse i et JPanel, der har et Verticalt BoxLayout, og er centreret. Hvorefter man ville kunne inds�tte dette JPanel i et JScrollPane.
Dette kunne jeg dog ikke helt f� lov til, da JScrollpane ikke fungerede ordentligt p� det JPanel jeg havde lavet.

Har I nogle gode ide�r til, hvordan man kan lave en Office word effekt i java swing (uden at benytte sig af eksterne api'er).

Panel bliver ikke vist f�r jeg resizer / Server p� router med java?

Tue, 14 May 2013 12:44:18 GMT

Hej alle!

- Jeg er igang med at lave en chat klient. Har mere eller mindre lavet layoutet, nu mangler jeg bare at kunne f� flere klienter til at kommunikere. Jeg ville godt pr�ve at s�tte en server op p� min router og lade det hele kommunikere over den. Hvordan skal jeg g�re det? Har ingen erfaring, s� bare s� meget som et API jeg kan bruge, eller en hjemmeside tut eller noget lign. ville jeg v�rds�tte! Jeg ved heller ikke hvordan jeg skulle s�tte min router op. Det skal bare v�re LAN til at starte med.

- Jeg har ogs� problemer med min kode lige her:

Java kode

 public void enterStages()
     {
         if(bmenu)
         {
             try
             {
                 this.remove(chat);
             }
             catch(Exception e){}
             System.out.println("Enters menu stage");
             this.add(menu);
         }
         else if(bchat)
         {
             try
             {
                 this.remove(menu);
             }
             catch(Exception e){}
             System.out.println("Enters the chat stage");
             this.add(chat);
         }

F�rste gang den metode bliver kaldt er bmenu == true. Der virker det hele fint. Men n�r s� bchat == true, s� f�r jeg problemer. Elementerne/komponenterne i det JPanel bliver ikke vist, medmindre jeg resizer vinduet manuelt.. What to do? o.o

Her er alt min kode:

Feedback/Gode forslag til forbedring

Thu, 14 Mar 2013 21:57:46 GMT

Hej Udviklere,

Jeg har siddet og rodet lidt med at lave en egen clipboard manager(var ved at blive tr�t af, at det kun var muligt at kopierer en ting ad gangen ).
Mine tanker omkring at lave det nemmere, var at se ens clipboard lidt ligesom i de fleste RPG spil, hvor man har en rygs�k, der kan indeholde et vist antal pladser. Og s� ville man kunne definerer hvilken plads man kunne kopierer og "s�t ind".
I applikationen, der k�rer i baggrunden v�lger man sine placering i sin rygs�k, ved at trykke CTRL + NUMPAD[0-9], hvor at tallet definerer placeringen.

For at afslutte applikationen, n�r den er startet skal man g� ned i sit SystemTray og h�jre klikke p� lys p�re ikonet, og trykke p� Exit.

Den kan desv�rre kun k�rer p� windows i �jeblikke.

Noget der ville v�re �nskeligt at f� feedback p�, var om det f�ltes simpelt at g� til ? og om der var en anden form for brugergr�nseflade, der var �nskelig ?.

M�den man starter det p� er ved at downloade denne .jar fil Link til .jar fil og herefter starte den som en runnable .jar fil (normalt betyder dette at man kan dobbelt klikke p� den)

JFrame.setVisible(false); - Hvad g�r det helt pr�cist?

Sun, 10 Mar 2013 12:11:04 GMT

Hvis JFrame.setVisible(false); hvad s�? Man kan ikke se vinduet, men k�rer programmet alligevel i baggrunden? Og hvorfor have en funktion som g�r det muligt, hvad er meningen med et vindue som ikke kan ses? o.o

Mit JLabel bliver ikke vist - bruger Keylistener

Tue, 29 Jan 2013 16:34:43 GMT

Jeg har et problem med mit program - skal have mit JLabel input vist p� sk�rmen - det f�r jeg dog ikke.. Meget frustrerende. Vil have den til at blive vist under bg(png).

Kan ikke bruge \n (newline) i mit JLabel, virker heller ikke med html tags

Fri, 14 Dec 2012 14:27:51 GMT

Hej alle! Har lavet et prompt vindue, og det skal fungere ligesom CMD; ved hver kommando skal den skrive output p� en ny linje, og n�r der ikke er mere plads i JLabel, skal den k�rer det hele en gang op s� den har plads til en ny linje. Vil ogs� gerne have en scrolle funktion, s�dan s� man kan se de �ldre kommandoer og output man har skrevet/f�et.

Java kode

 import java.awt.Color;
 import javax.swing.*;
 
 public class Window extends JFrame
 {
     Keyboard keys;
     
     JPanel panel;
     JLabel output, input;
     String command = "";
     String outputString = ">>> Welcome to DotMS! \ntest";
     
     public Window()
     {
         this.setVisible(true);
         this.setDefaultCloseOperation(EXIT_ON_CLOSE);
         this.setSize(600, 400);
         
         keys = new Keyboard(this);
         this.setFocusable(true);
         this.addKeyListener(keys);
         
         panel = new JPanel();
         this.add(panel);
         panel.setLayout(null);
         panel.setOpaque(true);
         panel.setBackground(Color.BLACK);

F�r udelukkende outputtet "Welcome to DotMS! test"

L�sning af fil, output til JFrame, output vises ikke?

Thu, 13 Dec 2012 10:36:43 GMT

Hej alle. Har lavet mit hidtil st�rste system, but no work, pr�vede at k�re min klasse fileReader i et lukket test projekt i Eclipse, der fungerede det, men n�r jeg kobler det p� resten af systemet, med JFrame, JLabels, keylistener osv s� virker det ikke.

N�r jeg skriver en kommando i min lille "kommandoprompt" og pr�ver at eksekvere kommandoen, s� f�r jeg intet output..

Please help!

Hvordan positionere man JLabels?

Mon, 10 Dec 2012 21:16:22 GMT

Hej alle! Har problemer med at positionere mine JLabels, selv om jeg bruger Label.setBounds(x, y, width, length); kommer det hele bare p� f�rst linje >.<

- Er det fordi jeg skal bruge en anden layoutmanager?

her er min kode:

     public Window()

Formering af firkanter med Java

Sun, 09 Dec 2012 16:41:00 GMT

Hej alle!
Jeg er igang med at lave et lille program i Java med swing. Har lavet et JFrame og har tilf�jet et JPanel til JFrame. Jeg har tegnet en stor firkant i mit panel, og har lavet en MouseListener klasse. Jeg vil have mit program til, at hver gang man f�rer musen "ind" i en firkant, formere den sig, til 4 mindre firkanter. Der er alts� til at starte med kun 1 firkant, og n�r man r�r den med musen, s� splitter den sig op i 4 mindre firkanter, som tilsammen udfylder det samme areal som den f�rste firkant. S� n�r man r�r en af de andre sm� firkanter splitter den sig op i 4 osv osv. Jeg skal have tilf�jet min mouselistener klasse til hver firkant der bliver lavet, men indtil videre har jeg bare tegnet dem p� sk�rmen, jeg skal bruge en eller anden form for variabel-firkant. How to do?

Tak p� forh�nd :-D

Lidt hj�lp til java, og Threading

Sun, 27 May 2012 11:42:24 GMT

Hej Udviklere,

Jeg har siddet, og rodet lidt med et problem. Dette problem omhandler, at i programmet, har jeg 2 dele. En visuel del og en beregnings del, og jeg ville gerne have, at de k�re p� en s�dan m�de, s� n�r beregnings delen har beregnet en del, s� bliver visualiseringen opdateret. Indtil videre er det design, der er lagt ind i det p� f�lgende m�de:

Beregnings delen startes
K�re en beregning og sender beregningen til en Observer
Denne Observer, sender det s� direkte videre til vores visualiserings del.

Koden for den del, hvor beregnings delen startes er her:

Opstilling af data i JTabel eller andet

Thu, 08 Dec 2011 10:42:29 GMT

Hall�j Udviklere.

Jeg st�r og skal lave noget Data opstilling i mit program.

Lad mig f�rst forklare lidt, der er tale om mit eksamens projekt, som g�r ud p� at lave et tekst based rollespil, i den forbindelse skal vores spiller have et inventory. Her skal alle hans items alts� blive listet, med mulighed for at "Equip" de ting han har it sit inventory.

Som det er nu har jeg lavet en JTabel, som viser navn p� item, stats etc. men jeg skal have knyttet en equip knap p� hvert v�ben, problemet er at det �benbart ikke er lige s� nemt som man skulle tro, swing er fandeme noget lort.

Men jeg er herefter kommet i tvivl om at det overhoved er den rigtige fremgangs metode, hvordan ville i stille det op, s� jeg kan forbinde med en equip knap. Ville i overhoved bruge en JTable?
Kom gerne med flere muligheder

Tak.

[EDIT.]

Lige et billede, s� i kan se hvordan det ser ud nu, det er dog uden equip knappen, som jeg ikke kunne f� til at spille. :/

Gode id�er

Wed, 07 Dec 2011 17:29:58 GMT

Hej alle herinde p� udvikleren,

S� har jeg siddet, og jule hygget lidt i en 1� times tid, og havde lige lyst til at vise jer resultaterne

Det jeg har fors�gt p� at lave er en version af det kendte spil Space-Shooter, som I kan se et billede af her .

ScreenShoot

Eller, hvis I skulle have lyst til at pr�ve spillet og komme med nogle id�er til forbedringer, s� kan det hentes i .jar format her: Selve Spillet

Hvordan skifter jeg imellem JTextFields med Tabulator?

Thu, 03 Nov 2011 22:11:38 GMT

Hej allesammen

Jeg er i gang med et mindre projekt, og har i dette lavet en mindre 'formular', opbygget ved hj�lp af et Grid Layout, med 6 r�kker og 2 kolonner. Formularen best�r s� af henholdsvis et JLabel og et JTextField, for hver r�kke.

Mit Sp�rgsm�l er s� nu, at jeg syntes det ville v�re rart, hvis jeg bare kunne benytte min tabulator knap for at skifte fra det f�rste JTextField, til det n�ste JTextField. Alts� s�dan at hvis fokus er p� JTextField nummer 1, s� skal den skifte til JTextField nummer 2 ved et klik p� Tabulator knappen. Ligeledes hvis fokus er p� JTextField nummer 2 i formularen, skal et klik p� Tabulator knappen skifte fokus til JTextField nummer 3. Mit sp�rgsm�l er s� nu, hvordan laver man dette?

Jeg syntes at have s�gt en del p� nettet nu, og kunne desv�rre ikke finde et svar der passede ind, men h�ber at nogle af jer har en l�sning p� mit problem

Ellers god Weekend til alle!

Disable font-smoothing java applet

Wed, 02 Nov 2011 00:00:41 GMT

Nogen der ved hvordan jeg kan fjerne font smoothing i en applet?

Kan g�re det med en applikation med:

Java kode

 System.setProperty("swing.aatext" "false");

Men det virker ikke hvis k�rer applet'en i en browser.

Java Swing

Wed, 20 Apr 2011 21:15:20 GMT

Hej alle udviklere!

Jeg har et problem som jeg simpelthen ikke kan l�se.

Jeg er ved at lave et program med Java Swing.
Jeg har lavet en hovedoverskrift med JLabel. Nu pr�ver jeg p� at lave en under-overskrift, som, som navnet antyder, skal v�re under overskriften. Problemet er at jeg ikke kan finde en l�sning til hvordan jeg putter underoverskrifts-label'en under den f�rste. Jeg har pr�vet setVerticalAlignment, setVerticalTextPosition og en milliard andre ting.

Jeg bruger JFrame med layoutet FlowLayout.

Er der nogen der har en l�sning?
