Do you have an example?

Thanks for your answer and agree with you, I will try to understand what is the problem.

P.S: The develop a new L&F is hard but is cool if you want generate feedback this is the project

Thanks for sharing your opinion about the post

In my opinion, I think the error is href="../resources/bs2/css/style.css"

When I use JSF I write the reference with the request.contextPath, like this <link rel="stylesheet" href="#{request.contextPath}/css/personal.css" type="text/css" />

In my cases, the CSS is inside the application root, if your resources dir is in your root, try to use this code.

P.S: My I miss my JSF rules and I don't test this solution, but should be a test.

If you want an example, you can try this code

@Override    public void actionPerformed(ActionEvent e) {        Frame frame = (Frame) App.getInstance().getInstanceObject(IFrameApp.class);        PanelPresentation presentation = (PanelPresentation) App.getInstance().getInstanceObject(IPresentationPanel.class);        JFileChooser fileChooser = new JFileChooser();        if(JFileChooser.APPROVE_OPTION == fileChooser.showSaveDialog(frame)){            String path = fileChooser.getSelectedFile() + ".png";            int w = presentation.getWidth();            int h = presentation.getHeight();            BufferedImage bi = new BufferedImage(w, h, BufferedImage.TYPE_INT_RGB);            Graphics2D g = bi.createGraphics();            presentation.paint(g);            g.dispose();            File outputfile = new File(path);            try {                ImageIO.write(bi, "png", outputfile);                //MaterialTost.makeText(frame,"Image stored :)", MaterialTost.SUCCESS).display();            } catch (IOException ex) {                LOGGER.error(ex.getMessage());                frame.doShowMessage(MessageLevelError.ERROR, ex.getMessage());            }        }    }

You can found a demo here

How you load the CSS inside your error page?

Hi all.

I hope you are safe and healthy.

I want to talk about a problem with load personal font inside application java Swing.

I'm developing a new Open-source L&F that import material style in swing, now in at this time I'm losing with a problem with a Java font.

I will describe the problem.

I'm loading the font with this code

private FontUIResource loadFont(InputStream inputStream, boolean withPersonalSettings) {        float size = this.doOptimizingDimensionFont(this.defaultSize);        if (withPersonalSettings && fontSettings.isEmpty()) {            fontSettings.put (TextAttribute.SIZE, size);            fontSettings.put(TextAttribute.KERNING, TextAttribute.KERNING_ON);            //int style = whatIsTypeFont();            //fontSettings.put(TextAttribute.FAMILY, (style & ~0x03) == 0 ? style : 0);        }        try {            Font font;            if(withPersonalSettings){                font = Font.createFont(Font.TRUETYPE_FONT, inputStream).deriveFont(fontSettings);                return new FontUIResource(font);            }            font = Font.createFont(Font.TRUETYPE_FONT, inputStream).deriveFont(size);            System.out.println(font);            return new FontUIResource(font);        } catch (IOException | FontFormatException e) {            e.printStackTrace();            throw new RuntimeException("Font " + inputStream.toString() + " wasn't loaded");        }    }    public float doOptimizingDimensionFont(int dimension){        if(defaultSize <= 0){            throw new IllegalArgumentException("\n- The dimension should be positive (>= 0)");        }        return dimension * Math.min(Toolkit.getDefaultToolkit().getScreenResolution(), 96) /72;    }

I think after you read the code, you have a question, Why you calculate the dimension font with this formula:   dimension * Math.min(Toolkit.getDefaultToolkit().getScreenResolution(), 96) /72;

The answer at your question is because if I only the dimension inside the font, I see the pixeled result, like this



If I use the screen resolution I can fix this problem and the result is this



But, now I have a problem with dimension font with a display with high resolution, the font is very small, as these pictures



Now I'm thinking of building a solution, as to create a set of default dimensions, For example, XXX_DISPLAY, XX_DISPLAY, X_DISPLAY.
This solution was implemented inside the android framework when adapting the icon at different screen dimensions.

But Before starting work I want to talk and exchange ideas about this problem.

I'm losing somethings to calculate correctly the font dimension?

P.S: I noted that with the JDK version >= 10 the pixel effect if not present but with JDK 8 is present.

Hi, I lose this message, sorry.

Today I will try this solution and I will return here to know the result.

Thanks for your time.

Thanks for your time.

I added this this.tabPane.setToolTipText("TEST"); and don't have any result.

I'm sorry :/

HI,

I want to add mouse hover on the Tab Pane, the mouse hovers effect desired is very simple, it should change the cursor when the mouse is over the tab name.

I'm doing an example, I have the component MateriaTabblePaneUI with this mouse event:

protected class MaterialMouseHoverTab implements MaterialMouseHover {        private Rectangle[] rectangles;        public MaterialMouseHoverTab(Rectangle[] rectangles) {            this.rectangles = rectangles;        }        @Override        public void mouseDragged(MouseEvent e) {        }        @Override        public void mouseMoved(MouseEvent e) {            MaterialLogger.getInstance().debug(LOG_TAG, "Called method mouseMoved inside MaterialMouseHoverTab class");            JComponent mouseGenerate = (JComponent) e.getSource();            if (!mouseGenerate.isEnabled()) {                return;            }            if (mouseGenerate.getCursor().equals(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR))) {                return;            }            Point point = e.getPoint();            for (Rectangle r : rectangles) {                if (r.contains(point)) {                    mouseGenerate.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));                    return;                }            }            mouseGenerate.setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));        }     //other empity method    }

I add the method when the component is painted, so this @Override    protected void paintTab(Graphics g, int tabPlacement, Rectangle[] rects, int tabIndex, Rectangle iconRect, Rectangle textRect) {        // for some reason tabs aren't painted properly by paint()        super.paintTab(MaterialDrawingUtils.getAliasedGraphics(g), tabPlacement, rects, tabIndex, iconRect, textRect);        //TODO Should be the cause of StackOverflowException        if (mouseHoverEnabled != null && mouseHoverEnabled && mouseHoverTab == null) {            mouseHoverTab = new MaterialMouseHoverTab(rects);            tabPane.addMouseMotionListener(mouseHoverTab);        }    }

But this event run on all JTabbledComponent and I want to add this effect only on the text of the jTabbledPane, like "Panel1" or "Panel2"

I found this answer on stack overflow, but not use the component BasicTabbledPaneUI https://stackoverflow.com/a/4228349/10854225

I want to make this change because I want optimized the code and I need to help to find some good idea.

The desired effect is

MouseHover effect



Thanks for your time

public boolean canDisplay(char c) {  return font1.canDisplay(c) || font2.canDisplay(c); }

That would be tedious but I'm sure it's not beyond your abilities. The only problem you would have would be when you had to load that "font" from a TTF file, but possibly that wouldn't happen.

Hi, thanks for your help, I will examine your solution to create the personal font; I will return here with the result.

Hi guys,
I have a question on adding the support of the Emoji to my personal look-and-feel, I'm the developer of  material-ui-swing and I'm using the "Noto Sans" for font and it doesn't support the emoji (like ♥).
I'm loading the font, Noto Sans, with code like this
try {     GraphicsEnvironment ge =         GraphicsEnvironment.getLocalGraphicsEnvironment();     ge.registerFont(Font.createFont(Font.TRUETYPE_FONT, new File("A.ttf"))); } catch (IOException|FontFormatException e) {     //Handle exception }

This is the actual visive effect


Well, now I want to add Noto Color Emoji inside the look-and-feel but I don't know a method for using "Noto Sans" and "Noto Color Emoji" together.
PS: I know only one method for support this, and I must join the file fonts described inside this question on stack forum.
Exist another solution to this problem with Java?
Thanks your help.

This question onreddit

I want a solution to this post,

The problems were two

In my personal look and feel I have used the Color and not the ColorUIResources

The JFileChooser was created in the action and not was add inside the JFrame, so when I got to change theme the look is weong

You already have an answer. So why have you not replied to this question stating the answer so people don't spend time answering a question that already has an answer?

I would have done it, as soon as I returned home, because I don't have my PC behind, on other occasions I always kept my questions updated in case of solutions in other forums. I just need some time, questions of hours, sorry

I'm developing a new look and feel and now I have a bug with the component JtextField, when to use it inside the JTabbledPane component.

So the bug is this

The button Border is painted with method paintBackground() inside the BasicButtonUI, you can change the border with the graphics object
