I'm designing an application and I want to set a space on the side. My problem now is, I'm using the FormLayout, and the FormAttachment can only define the percentage of the layout; so whenever the editor get wider(i have scrolledComposite in the background), the side space gets wider too, in which I hope it can remain as a same size. Does anyone has idea about how to solve this problem? thanks in advanced.
FormData data = new FormData();
data.left = new FormAttachment(5);
data.top = new FormAttachment(5);
data.right = new FormAttachment(95);
Label1.setLayoutData(data);
You can specify an offset value on the FormAttachment to specify the number of pixels to offset the attachment, so:
data.left = new FormAttachment(0, 50);
data.right = new FormAttachment(100, -50);
positions at the left and right with a fixed 50 pixel offset.

I am using a TextButton to create a dialog bubble effect in my game.
I have created the nine patch file as on the picture
everything seems to be fine until I try to use this bubble.9 with LibGDX, the TextButton is not stretching correctly based on the text height.
You can see that a multilines text extends the TextButton height but not correctly.
Here is the code
Load the bitmap font
FileHandleResolver resolver = new InternalFileHandleResolver();
assetManager.setLoader(FreeTypeFontGenerator.class, new FreeTypeFontGeneratorLoader(resolver));
assetManager.setLoader(BitmapFont.class, ".ttf", new FreetypeFontLoader(resolver));
FreetypeFontLoader.FreeTypeFontLoaderParameter dialogFont = new FreetypeFontLoader.FreeTypeFontLoaderParameter();
dialogFont.fontFileName = Conf.ASSET_FONT;
dialogFont.fontParameters.size = 8;
Initialize the TextButtonStyle
NinePatch patch = atlas.createPatch("bubble");
NinePatchDrawable dialogBoxPatch = new NinePatchDrawable(patch);
buttonStyle = new TextButton.TextButtonStyle();
buttonStyle.up = dialogBoxPatch;
buttonStyle.down = dialogBoxPatch;
buttonStyle.checked = dialogBoxPatch;
buttonStyle.over = dialogBoxPatch;
buttonStyle.font = dialogFont;
buttonStyle.fontColor = Color.BLACK;
actual rendering
dialogBox = new TextButton("some\ntext", buttonStyle);
dialogBox.draw(batch, 1);
Does someone see what the problem is?
I finally found the problem.
I have decided to test the ninepatch with another font and it worked like a charm. To understand what was going on, I have opened the two fonts with glyphrstudio. It appears that the problematic font is not correctly designed.
Bad font
Good font
You can see that the base line and capheight are not correctly setted on the bad font.
I hope this will help other people facing the same problem.
I want to move text with iText7. I have a source bounding box, that can be somewhere on the page and I have a target bounding box, that has a fixed position (incl. width and height). I'll stay on the same page. The source and target boxes can overlap. The source bounding box can also be larger than the target box. In this case I have to reduce the font size. The text should retain font, color and so on.
There is a cut and paste example on the iText website . But in the result pdf file you can select the text at the new and old position (tried it only with a normal pdf reader). I don't want the text to be selectable at the old position.
I thought, that maybe I could select the text and just place it at the new position and remove it from the old position. For the latter i would need pdfSweep, but this is ok. Adding the text at the new position should be no problem. Even if the text has different fonts, sizes and so on. There are plenty of examples on the iText website. The only way I know to select the text is like shown in this example. This gives me only the text. But to place it at the target position with the same font, color and so on, I need all those informations, too.
I know, that pdf is not meant for editing. This is often mention in answers on StackOverflow.
Is there a way to do this with iText7?
There is no high level API in iText allowing you to move page content, in particular not all content from some rectangle. One reason may be that in general this is no mere moving. PDFs often contain structures influencing larger areas, and such structures would not simply have to be moved but instead copied, and each copy restricted to its area.
It is indeed possible, though, to combine the cut and paste example the OP found with the pdfSweep module already considered by the OP to a solution which prevents the text from being selectable at the old position, e.g. like this:
public void moveCleanSection(PdfReader pdfReader, String targetFile, int page, Rectangle from, Rectangle to) throws IOException
{
LicenseKey.loadLicenseFile("itextkey-multiple-products.xml");
ByteArrayOutputStream interimMain = new ByteArrayOutputStream();
ByteArrayOutputStream interimPage = new ByteArrayOutputStream();
ByteArrayOutputStream interimSection = new ByteArrayOutputStream();
try ( PdfDocument pdfMainDocument = new PdfDocument(pdfReader);
PdfDocument pdfPageDocument = new PdfDocument(new PdfWriter(interimPage)) )
{
pdfMainDocument.setCloseReader(false);
pdfMainDocument.copyPagesTo(page, page, pdfPageDocument);
}
try ( PdfDocument pdfMainDocument = new PdfDocument(pdfReader, new PdfWriter(interimMain));
PdfDocument pdfSectionDocument = new PdfDocument(new PdfReader(new ByteArrayInputStream(interimPage.toByteArray())),
new PdfWriter(interimSection)) )
{
List<PdfCleanUpLocation> cleanUpLocations = new ArrayList<PdfCleanUpLocation>();
cleanUpLocations.add(new PdfCleanUpLocation(page, from, null));
cleanUpLocations.add(new PdfCleanUpLocation(page, to, null));
PdfCleanUpTool cleaner = new PdfCleanUpTool(pdfMainDocument, cleanUpLocations);
cleaner.cleanUp();
cleanUpLocations = new ArrayList<PdfCleanUpLocation>();
Rectangle mediaBox = pdfSectionDocument.getPage(1).getMediaBox();
if (from.getTop() < mediaBox.getTop())
cleanUpLocations.add(new PdfCleanUpLocation(1, new Rectangle(mediaBox.getLeft(), from.getTop(), mediaBox.getWidth(), mediaBox.getTop() - from.getTop()), null));
if (from.getBottom() > mediaBox.getBottom())
cleanUpLocations.add(new PdfCleanUpLocation(1, new Rectangle(mediaBox.getLeft(), mediaBox.getBottom(), mediaBox.getWidth(), from.getBottom() - mediaBox.getBottom()), null));
if (from.getLeft() > mediaBox.getLeft())
cleanUpLocations.add(new PdfCleanUpLocation(1, new Rectangle(mediaBox.getLeft(), mediaBox.getBottom(), from.getLeft() - mediaBox.getLeft(), mediaBox.getHeight()), null));
if (from.getRight() < mediaBox.getRight())
cleanUpLocations.add(new PdfCleanUpLocation(1, new Rectangle(from.getRight(), mediaBox.getBottom(), mediaBox.getRight() - from.getRight(), mediaBox.getHeight()), null));
cleaner = new PdfCleanUpTool(pdfSectionDocument, cleanUpLocations);
cleaner.cleanUp();
}
try ( PdfDocument pdfSectionDocument = new PdfDocument(new PdfReader(new ByteArrayInputStream(interimSection.toByteArray())));
PdfDocument pdfMainDocument = new PdfDocument(new PdfReader(new ByteArrayInputStream(interimMain.toByteArray())), new PdfWriter(targetFile)) )
{
float scale = Math.min(to.getHeight() / from.getHeight(), to.getWidth() / from.getWidth());
pdfSectionDocument.getPage(1).setMediaBox(from);
PdfFormXObject pageXObject = pdfSectionDocument.getFirstPage().copyAsFormXObject(pdfMainDocument);
PdfPage pdfPage = pdfMainDocument.getPage(page);
PdfCanvas pdfCanvas = new PdfCanvas(pdfPage);
pdfCanvas.addXObject(pageXObject, scale, 0, 0, scale, (to.getLeft() - from.getLeft() * scale), (to.getBottom() - from.getBottom() * scale));
}
}
(From MoveSectionCleanly.java)
Beware: Due to the nature of pdfSweep, text being on the border of the source area is removed both from the source and the copy of it.
In the code it is pretty easy:
// Clip
Rectangle rect = new Rectangle(168, 168);
rect.setArcHeight(30);
rect.setArcWidth(30);
rect.setEffect(new Reflection());
imageView.setClip(rect); //where imageView is an ImageView
I am trying to do it using SceneBuilder but i don't know
how..Any help will be appreciated.
If i well understood you are trying to populate a node (like a box or box or a pane or whatever you want)with your object rectangle, i think it's not possible doing it from the Scene Builder, you must do it from the code.
If you want to do it you have add it to a subScene i think!
PerspectiveCamera camera = new PerspectiveCamera();
ImageView imageview = new ImageView();
Rectangle rect = new Rectangle(168, 168);
rect.setArcHeight(30);
rect.setArcWidth(30);
rect.setEffect(new Reflection());
imageview.setClip(rect);
Group g = new Group(imageview);
SubScene subSceneInsertion = new SubScene(g, 919, 600, true, SceneAntialiasing.BALANCED);
subSceneInsertion.setFill(Color.DARKSLATEGREY);//yourcolour
subSceneInsertion.setCamera(camera);
Group groupForSubScene = new Group(subSceneInsertion);
groupForSubScene.autoSizeChildrenProperty().setValue(Boolean.TRUE);
groupForSubScene.setAutoSizeChildren(true);
hBoxForRectangle.getChildren().add(groupForSubScene);
I'm need to modify letter-spacing (font tracking) in a JTextPane, and I can't get it to work.
When I'm using a JTextArea, I can just do:
Font font = new Font("Courier New", Font.PLAIN, 10);
HashMap <TextAttribute, Object> attrs = new HashMap<TextAttribute, Object>();
attrs.put(TextAttribute.TRACKING, -0.1);
font = font.deriveFont(attrs);
textArea.setFont(font);
but as I need to change line spacing, I need to use a JTextPane, and doing:
textPane.setFont(font)
as I did with the JTextArea doesn't work. another thing I tried was:
MutableAttributeSet set = new SimpleAttributeSet();
StyleConstants.setLineSpacing(set, -0.2);
StyleConstants.setFontFamily(set,"Courier New");
StyleConstants.setFontSize(set, 10);
set.addAttribute(TextAttribute.TRACKING, -0.1);
ta.setParagraphAttributes(set, true);
But the tracking attribute doesn't work.
What am I doing wrong?
Do you mean kerning? This one shows how to specify custom kerning and some more text effect

I am trying to make GUIs in SWT using Jigloo and when I want to set images to Labels or Buttons, I can see them in the preview pane. However, when i compile and run it, it throws
SWTResourceManager.getImage: Error getting image img/game/front/test.png, java.lang.IllegalArgumentException: Argument cannot be null
The code it generates looks like this:
opIcon = new Label(this, SWT.NONE);
FormData opIconLData = new FormData();
opIconLData.width = 64;
opIconLData.height = 64;
opIconLData.left = new FormAttachment(0, 1000, 12);
opIconLData.top = new FormAttachment(0, 1000, 12);
opIcon.setLayoutData(opIconLData);
opIcon.setImage(SWTResourceManager.getImage("img/game/front/test.png"));
The SWTResourceManager class seems to be largely undocumented so I'm kinda lost here. Any help?
This method requires an absolute path,
SWTResourceManager.getImage("/home/img/game/front/test.png");
